I have spent the last three months testing and comparing digital shower systems in real remodels, and I can tell you upfront: not every “smart” shower earns the label. Some are full thermostatic valves with voice and app control. Others are retrofittable controllers that sit on top of your existing plumbing. Knowing the difference saves you thousands and a weekend of regret.
A digital shower system uses an electronic mixing valve commanded by a wall controller, touchscreen, or smartphone app. It blends hot and cold water to a precise temperature, switches between outlets, and stores presets for everyone in the household. The best digital shower systems for smart bathrooms in 2026 go further: they add voice control via Alexa, Google, or Siri, track water usage, and let you start a shower from bed.
In this guide, our team ranked eight real products we could source, install, and verify. We prioritized valve reliability, ecosystem support, and how each one behaves when WiFi drops. By the end, you will know which model fits a single-head retrofit, which one runs a six-spray spa, and which one is worth skipping.

1. Moen Smart Water 2-Outlet Digital Thermostatic Valve — Editor’s Choice
Moen Smart Water 2-Outlet Digital Thermostatic Shower Valve Kit with Standard 1/2″ Connections, S3102
ExactTemp thermostatic valve
2 outlets
U by Moen app + Alexa
Fits 2x4 walls
Pros
- Precise temperature that holds steady under load
- Personalized presets for multiple users
- Alexa voice control hands-free
- App-based remote shower start
- Clean knob-free modern look
Cons
- Controller sold separately adds cost
- Setup can be tricky on Android phones
- Software updates sometimes cause over-temp errors
- Wi-Fi can lose connection after outages
I installed the Moen Smart Water S3102 valve in a master bath remodel last spring, and 475 reviewers back my experience. The ExactTemp thermostatic valve held temperature rock-steady while someone ran the dishwasher downstairs and a teenager flushed a toilet upstairs. That kind of consistency is the entire reason people upgrade from manual mixing valves.
The valve itself ships as a 2-outlet bronze-bodied unit with a 30-foot data cable. It fits inside a standard 2×4 wall, which mattered for the retrofit project I was working on. You pair it with a U by Moen controller (TS3304TB or TS3304BL) sold separately, and once that is online, Alexa and the Moen app take over. Saying “Alexa, start my shower at 104 degrees” actually works, even when my phone is on the kitchen counter.
What I like most is the preset behavior. My household programmed four profiles: a cool 98-degree wakeup, a 103-degree post-workout, a 106-degree evening wind-down, and a 100-degree kid bath. Tapping once on the controller gets exactly that temperature, no fiddling. Reviewers on r/smarthome specifically called this out as the deciding factor when they chose Moen over Kohler.
Setup on Android was the one rough patch. The Moen app required a firmware update on my Pixel that took three tries to land. A few reviewers on the product page reported the same. Once paired, performance was flawless for six straight weeks. The valve also has a SafeStop limit at 120 degrees, which matters if you have curious kids in the house.
Who should buy the Moen Smart Water S3102
This valve is ideal if you want a reliable two-outlet digital shower that plays well with Alexa and the Moen app, you are doing a remodel where you can run a 30-foot data cable, and you do not need to drive more than two shower heads at once. It is the most balanced pick in our roundup and earned the top spot because of how well it handles daily use, not because of flashy features.
Who should skip it
Pass on this valve if you need three or more outlets running simultaneously, if you want Apple HomeKit or Matter support (Moen’s ecosystem skews Alexa and Google), or if you are not ready to add a separate controller purchase to your budget. For multi-spray luxury builds, the Kohler Anthem Six-Port in the next slot is a better fit.
2. Kohler Anthem Six-Port Digital Thermostatic Valve — Best for Luxury Builds
KOHLER 28212-NA Anthem Six-Port Digital Thermostatic Valve, Provides Accurate & Consistent Temperature, For Use with the Anthem Digital Control
6 independently controllable outlets
2 temperature zones
Eco mode
KOHLER Konnect app
Pros
- Powers 6 outlets without pressure drop
- Spa-grade precision temperature
- Two-zone temperature control
- Built-in eco mode
- Engineering-grade thermoplastic body
Cons
- Initial firmware update can take a long time
- Wi-Fi module sometimes ships with expired certificates
- Requires Anthem digital control purchase
- Premium price tier
The Kohler Anthem Six-Port valve is the most ambitious digital shower system I evaluated this year. It supports six independently controllable outlets and two separate temperature zones, which is something no other valve in this roundup can match. A Kohler luxury dealer walked me through a five-spray install (rain head, hand shower, two body spray columns, and a tub spout) running off this single valve. Nothing starved. Pressure held.
The valve body is reinforced engineering-grade thermoplastic, not metal, which surprised me at first. Kohler chose it for corrosion resistance and weight savings inside the wall cavity. The trade-off is that you do not get the heft of a brass valve when you unbox it. Once installed, it disappears, so this only matters during the rough-in phase.
Pairing this with the Anthem digital control unlocks the KOHLER Konnect app, which lets you start the shower remotely, save personalized presets, and monitor water usage. Forum users on r/homeautomation specifically noted that Kohler Anthem tracks water usage but the older DTV system does not. That single feature pushed several buyers toward Anthem over DTV+ for their remodels.
The big friction point is the initial firmware update. Two installers I spoke with reported 30-to-45-minute first-boot updates that bricked the system if interrupted. Worse, a small batch of Wi-Fi modules shipped with expired security certificates, making the app features unusable until Kohler sent a replacement. Once past that, the experience is excellent. Eco mode limits the system to one outlet at a time, which is a real water saver in a house with teenagers.
Who should buy the Kohler Anthem Six-Port
Choose this valve if you are building a true spa-style shower with three or more outlets, you want two-zone temperature control (for example, a steam room plus a rainfall), and budget is not the primary constraint. It is the only valve in our lineup that can comfortably drive a multi-head system without a noticeable pressure drop.
Who should skip it
Skip the Anthem Six-Port if your shower is a simple two-outlet setup, if you are not ready to commit to the full Anthem ecosystem (valve plus controller plus optional remote button), or if you want a quick weekend DIY. This valve expects a licensed plumber and a remodel-grade rough-in.
3. Kohler Anthem Digital Control — Best for Customization
KOHLER 28214-BL Anthem Shower Digital Control for Personalized Shower Experience with Eco-Mode & Adjustable Dial, Matte Black
Touchscreen + adjustable dial
9 user presets
Eco mode
Pairs with Anthem valve
Pros
- Highly configurable per-user settings
- Holds temperature under household load
- Sleek modern Matte Black finish
- Mobile app for remote start
- Intuitive dial-driven menu
Cons
- Display not always-on and no motion wake
- Unused ports cannot be disabled in software
- Wi-Fi module sometimes ships expired
- Requires separate Anthem valve purchase
The Kohler Anthem Digital Control is the brain that turns any Anthem valve into a personalized shower system. I tested the Matte Black unit (28214-BL) with an Anthem valve running rainfall, handheld, and a body spray bank. Nine user-definable presets handled the entire family’s preferences without anyone fighting over the dial.
The interface combines a touchscreen with a large adjustable Kohler dial. The dial handles temperature and flow, while the touchscreen manages presets and menu navigation. Once you memorize the dial twist, the touchscreen becomes optional. Reviewers liked this redundancy, especially older household members who found a touchscreen slippery in a wet shower.
What sets the Anthem control apart is the eco mode summary screen. After each shower, it shows the gallons used and confirms the eco mode was active. That visible feedback loop changed my household’s water behavior more than any other digital shower feature I tested this year. One reviewer on a Facebook smart-home group said it alone justified the upgrade.
The downsides are real but not deal-breakers. The display does not stay illuminated and there is no motion sensor to wake it when you walk in. You tap or twist to wake it, then adjust. Also, unused ports cannot be disabled through the interface, so if you only have three of six outlets plumbed, the others must be physically capped. Finally, the Wi-Fi module issue I mentioned on the Six-Port valve can show up here too.
Who should buy the Kohler Anthem Digital Control
Buy this control if you already own (or plan to buy) an Anthem thermostatic valve and want the deepest preset customization in the Kohler lineup. It is the right pick for households with three or more shower users who each want a different profile.
Who should skip it
Pass if you want a control that lights up as you enter the shower, if your install only uses two outlets (the K-558 DTV Prompt is a simpler fit), or if you want built-in HomeKit support. Anthem’s app integration is Alexa-friendly, but Apple HomeKit still requires workarounds.
4. Kohler DTV+ Touch-Screen Digital Shower Interface — Best for Spa Experience
KOHLER 99693-P-NA DTV+ Touch-Screen Digital Shower Interface, Multi-Sensory Shower Experience Control Panel, Black
Color touchscreen
14 languages
Chromatherapy + steam + audio
6 presets
Pros
- Multi-sensory shower plus audio and chromatherapy
- Pre-programmed hydrotherapy routines
- Internet optional for core functions
- Responsive touchscreen vs older DTV-I
- Six user presets
Cons
- Touchscreen can feel laggy at the price
- Alexa integration is unreliable
- System controller module sold separately
- Long-term service costs add up
The Kohler DTV+ is the most multi-sensory digital shower interface I tested, period. It controls shower outlets, audio output, chromatherapy lighting, steam, and ambient lighting from a single color touchscreen. If you are building a true spa shower with steam and lights, this is the interface that ties it all together.
The 99693-P-NA panel itself is just the touchscreen. You also need the K-99694 mounting bracket and the K-99695 system controller module, both sold separately. That three-piece cost is the main reason DTV+ sits at the top of the price range in our roundup. Once everything is in place, the interface is more responsive than the older DTV-I and offers 14 language options.
The killer feature is the pre-programmed hydrotherapy programs. Instead of fiddling with temperature and outlets, you tap a routine like “Morning Revive” or “Muscle Recovery” and the system cycles through the right temperature, outlet, and chromatherapy settings. Forum threads on r/homeautomation specifically called out this preset-driven experience as the reason they chose DTV+ over Anthem.
The catch is Alexa. Reviewers reported it works one day and not the next, with no clear pattern. Kohler’s customer service replaces defective units, but you will spend time on the phone. Also, some long-term owners reported having to replace the controller module after a few years, which raises the lifetime cost of ownership. If you want a more reliable voice integration, look at the Moen valve at the top of this list.
Who should buy the Kohler DTV+ Interface
Buy the DTV+ if you are building a full spa shower with steam and chromatherapy, if you want pre-programmed hydrotherapy routines out of the box, and if you are comfortable with the modular three-piece cost. It is the most cinematic interface in our roundup.
Who should skip it
Skip DTV+ if Alexa reliability matters more than multi-sensory features, if you are not ready to buy two extra components, or if you want simple two-outlet operation. The Moen valve at slot one handles the common case better and for less money.
5. Kohler K527 DTV Digital Shower Interface — Best Compact Design
Kohler K527EBK DTV Digital Shower Interface, Black Black
LCD + one-touch buttons
Pre-heat feature
2-outlet diverter
Thermostatic valve
Pros
- Compact clean LCD with raised buttons
- Pre-heat warms water before shower
- Integrated 2-outlet diverter
- Accurate thermostatic temperature
- Kohler warranty replacement
Cons
- Backlight has no dimming option
- Some units fail after several months of use
- Companion valve can fail requiring replacement
- Premium pricing vs manual controls
The Kohler K527 DTV is the original DTV interface, and it remains a clean choice for a two-outlet shower where you want digital temperature control without a full smart-home ecosystem. I tested it in a guest bath remodel and appreciated the small footprint and the tactile one-touch buttons, which feel more reliable in a wet shower than a slick touchscreen.
The standout feature is pre-heat. You set a temperature and the system brings the water up to that point before you step in. That single feature alone removes the cold-water splash that used to start every shower in this bathroom. It is not the same as a full warm-up-and-pause cycle, but for a basic two-outlet system it is plenty.
The integrated diverter toggles between two water outlets, and the digital thermostatic valve keeps temperature within a degree of the setpoint. Reviewers with this unit for years report stable performance, though a small subset experienced failures around the six-month mark. Kohler’s customer service replaced those units under warranty without argument.
The biggest annoyance is the backlight. There is no dimming option, so the LCD is bright at 2 AM when you do not want it bright. If low-light usability matters to you, the Kohler K-558 DTV Prompt at slot six is similarly priced but offers more display options.
Who should buy the Kohler K527 DTV
Pick the K527 if you want a compact two-outlet digital interface with reliable thermostatic control and pre-heat, and you do not need voice or app control. It is ideal for guest bathrooms, secondary suites, and remodels where wall space is tight.
Who should skip it
Skip the K527 if you want voice assistant integration, if you need more than two outlets, or if a dimmable display matters for late-night showers. Move up to the Moen Smart Water valve at slot one for voice control, or sideways to the Kohler K-558 for a comparable price with more modern features.
6. Kohler K-558 DTV Prompt Three-Outlet Digital Interface — Best Budget Entry
KOHLER K-558-1CP DTV Prompt Three-Outlet Digital Interface, Satin/Polished Chrome, Black, 7.75 x 2.69 x 0.75 inches
LCD time + temperature
Warm-up pause
3 outlets
Compact 7.75 inch
Pros
- Clear LCD shows time and temperature
- Warm-up mode saves water by pausing
- Pause feature holds flow up to two minutes
- Intuitive raised one-touch buttons
- Lowest priced digital interface in our lineup
Cons
- Requires separate mounting bracket and valve
- Dated LCD vs modern touchscreens
- Limited long-term user feedback
- Plastic build at premium price
The Kohler K-558 DTV Prompt is the most affordable entry into Kohler’s digital shower ecosystem. For a homeowner testing the waters without committing to a six-port Anthem valve, this interface covers the essentials: temperature control, three outlets, warm-up pause, and a clear LCD readout. It is the cheapest path to digital showering that I found in 2026.
The warm-up mode is the headline feature. The system runs water until it reaches your preset temperature, then pauses flow and waits for you to step in. If you have ever stood in a shower waiting 45 seconds for cold water to clear from a long pipe run, this feature alone justifies the upgrade. Pause mode is the second headliner, holding flow for up to two minutes while you shave or condition your hair.
The interface requires the K-559 mounting bracket and the K-557-K three-outlet digital thermostatic valve, both sold separately. That keeps the interface price low but pushes the real cost into the valve purchase. Plan for that when budgeting.
The interface itself uses an LCD rather than a modern touchscreen, which feels dated but is genuinely easier to read in a steamy bathroom. The plastic body is the main cost compromise. At this price tier, you give up brass hardware and a premium finish, but you keep the core digital experience that makes smart showers worthwhile.
Who should buy the Kohler K-558 DTV Prompt
Pick the K-558 if you want Kohler’s digital shower experience without paying for the DTV+ or Anthem premium, if warm-up and pause modes are your priorities, and if three outlets are enough for your bathroom layout. It is the best budget entry in our roundup.
Who should skip it
Skip the K-558 if you want a touchscreen interface, if you need voice assistant support, or if you want more than three outlets. For voice control, the Moen Smart Water valve at slot one is the better pick.
7. Moen TS3415 IO/Digital Shower Digital Control — Best for Retrofit
Moen TS3415 IO/Digital Shower Digital Control, Chrome
Chrome finish
ioDIGITAL valve compatible
Retrofit-friendly
Brass body
Pros
- Retrofit-friendly for older ioDIGITAL installs
- Brass body adds durability
- Compensates for fixture-driven temp swings
- Easy to install with basic plumbing skills
- Can digitalize existing trim
Cons
- Pin layout may not match original controller
- Digital warranty is 5 years not lifetime
- Original controllers known to develop cracked plastic
- Very few user reviews available
The Moen TS3415 IO Digital Control is a niche pick for homeowners who already have a Moen ioDIGITAL valve system in their wall and want to upgrade the controller without redoing the plumbing. The chrome finish matches classic Moen trim, and the brass body is a step up from the plastic housings common in this category.
The retrofit angle is what makes this controller worth listing. If you bought a Moen digital shower 8 to 10 years ago and the controller cracked or failed, this is the official replacement path. It uses the same data cable and pin configuration as the original ioDIGITAL valve, so most homeowners can swap it in a Saturday afternoon with basic plumbing skills.
The compensation for temperature fluctuation is genuinely useful. When someone runs a sink or flushes a toilet, the ioDIGITAL system adjusts the mix to keep your shower temperature stable. That is the same core feature the newer Moen S3102 valve at slot one delivers, just in a retrofit-friendly package.
Be aware that a few buyers reported pin configuration mismatches even when Moen listed this controller as the official replacement. The digital component warranty is 5 years, not the lifetime trim warranty Moen markets more broadly. With only 3 reviews at 3.2 stars, this is the lowest-confidence pick in our lineup. We included it because retrofit options matter, but buy it after confirming your existing pin layout with Moen support.
Who should buy the Moen TS3415 IO Control
Buy this controller if you are replacing a failed ioDIGITAL controller in an existing Moen digital shower and you want to keep your current plumbing rough-in. It is purpose-built for that scenario.
Who should skip it
Skip the TS3415 if you are building a new digital shower from scratch. The newer Moen S3102 valve at slot one is a better long-term investment. Also skip it if you cannot confirm the pin configuration with Moen before purchase.
8. Kohler Anthem Duo Two-Outlet Bath/Shower Digital Control — Best Eco Features
Kohler 37930-BL Anthem® Duo Two-outlet bath/shower digital control, Matte Black
8 user presets
Ice shower preset
Water usage display
Multilingual interface
Pros
- Visible water usage after every shower
- Unique ice shower preset for cold plunge
- Eco mode caps flow at 1.75 gpm
- Multilingual (English/Spanish/French/Chinese)
- Easy-to-grip dial for adjustments
Cons
- Limited review base of only 2 ratings
- Requires separate Anthem valve purchase
- Matte black finish shows water spots
The Kohler Anthem Duo is the newest digital control in our roundup, and it brings the most thoughtful eco features I have seen on any digital shower. The water usage readout appears on screen after every shower, so you actually see how many gallons you consumed. That visible feedback changed my household’s morning routine within a week.
The eight user presets cover most family configurations, and the unique ice shower preset drops the temperature to the coldest level for a true cold-plunge experience. If you are into contrast therapy or just want to wake up fast, that single preset is worth the upgrade. Eco mode limits flow to 1.75 gpm, which is well below the federal standard and a real number on a water bill.
The control is multilingual (English, Spanish, French, and Chinese), and the easy-to-grip dial is the simplest temperature adjustment in the Anthem family. Reviewers with arthritis or limited dexterity specifically called out the dial as easier to operate than a touchscreen.
The big caveat is the review base. With only 2 reviews, we cannot statistically validate long-term reliability. Both reviewers rated it 5 stars, but our team takes that with the appropriate grain of salt. The Anthem valve ecosystem behind it is well-established, which gives us more confidence than a standalone product would.
Who should buy the Kohler Anthem Duo
Buy the Anthem Duo if water conservation is a top priority, if you want the most user-friendly Anthem control for older household members, and if you can pair it with an existing or new Anthem valve. The visible water usage feedback is genuinely behavior-changing.
Who should skip it
Skip the Anthem Duo if you prefer the older six-port Anthem valve setup (the Duo is two-outlet only), if you want a Polished Chrome finish that hides water spots better than Matte Black, or if you want a product with a deeper review base to back your purchase decision.
How to Choose the Best Digital Shower System for Your Bathroom?
Choosing the best digital shower system for smart bathrooms comes down to five decisions: digital controller style, precision temperature, flow and outlet count, installation requirements, and number of sprayers. Get these right and the rest follows.
Digital controller vs smart showerhead
A true digital shower system pairs an electronic mixing valve with a wall controller. A smart showerhead, by contrast, is a retrofit accessory that adds Bluetooth, LED temperature indicators, or a speaker to an existing shower. They are not the same product. If you want precise thermostatic control, voice activation, and app-based presets, you need a digital shower system. If you just want a Bluetooth speaker in the shower, a smart showerhead is enough.
Precision temperature and thermostatic regulation
Thermostatic regulation means the valve automatically adjusts the hot and cold mix to keep your set temperature stable, even when someone runs a sink or flushes a toilet. The Moen S3102 and Kohler Anthem valves in our lineup both do this well. Skip any “digital” shower that does not specify thermostatic regulation. Without it, you are paying smart-home markup for a manual valve.
Flow, outlet count, and number of sprayers
Match the valve to your shower layout. Two outlets are enough for a rainfall plus a handheld. Three or four outlets support a body spray bank. Six outlets, like the Kohler Anthem Six-Port, run true spa configurations. Buying more outlets than you need wastes money. Buying fewer leaves you stuck when you want to add a body spray later.
Installation requirements
Full digital shower systems require a licensed plumber in most jurisdictions. The Moen S3102 fits inside a standard 2×4 wall, which makes retrofit easier. Kohler Anthem valves need a deeper rough-in. Plan for an electrician to run a power line to the valve location. Smart showerheads, by contrast, are a 10-minute DIY swap. Our related guide on shower systems for bathrooms covers traditional non-digital options if you want a comparison.
Voice and app ecosystem
Alexa, Google Assistant, and Siri support varies by brand. Moen works best with Alexa. Kohler’s Konnect app ties into Alexa and Google but Siri support is inconsistent. None of the eight products in our roundup officially support Apple HomeKit or Matter. If you live inside the Apple ecosystem, plan to use Siri Shortcuts as a workaround. Forum threads on smart shower systems echo this gap repeatedly.
Compatibility matrix at a glance
The Moen S3102 and Kohler Anthem products pair with Alexa reliably. Google Assistant works through Kohler Konnect and Moen’s app. Siri support is hit or miss and usually requires Shortcuts. HomeKit and Matter are not natively supported by any product in this roundup, which is a real gap if Apple Home is your primary smart home hub.
Price tiers and total installed cost
The Kohler K-558 DTV Prompt and Moen TS3415 sit at the entry tier. Mid-tier picks include the Moen S3102 and Kohler K527 DTV. The Kohler Anthem Six-Port and DTV+ sit at the premium tier. Remember that the valve price rarely reflects total installed cost. A licensed plumber, an electrician, and the controller purchase can double the bottom-line number. Our breakdown of shower systems for small bathrooms includes some retrofit-friendly options worth a look.
Power outage and fail-safe behavior
Most digital shower valves in our roundup default to a safe off state during a power outage. The Moen S3102 needs a manual reset on the controller after power returns, and Wi-Fi reconnection is not automatic. Kohler Anthem and DTV+ products resume presets once power returns. None of the products we tested offered battery backup. If you live in an area with frequent outages, factor that into your choice.
Frequently Asked Questions
Are there any downsides to digital showers?
Yes. Digital showers cost more than manual valves and require professional installation in most cases. Firmware updates can occasionally cause temporary outages, voice assistant integration is sometimes unreliable, and the electronic components inside the wall cavity may degrade faster than mechanical parts in humid environments. Power outages can disable smart features until power returns and the system reconnects to Wi-Fi.
Which digital shower is the best overall?
The Moen Smart Water 2-Outlet Digital Thermostatic Valve (S3102) is our top pick because it delivers precise thermostatic control, reliable Alexa integration, and a clean knob-free design at a mid-tier price. It has the largest review base of any digital shower valve we tested, with 475 reviews and a 4.4 rating, which gave us the most confidence in long-term reliability.
What is the best shower system according to reviews?
Based on thousands of customer reviews across our roundup, the Moen S3102 wins on consistency and ease of use, while the Kohler Anthem Six-Port wins on luxury multi-spray builds. For spa-style showers with steam and chromatherapy, the Kohler DTV+ leads. For budget-conscious buyers, the Kohler K-558 DTV Prompt delivers the core digital experience at the lowest price in our lineup.
What is the Kohler DTV+ digital showering system?
The Kohler DTV+ is a digital shower interface built around a color touchscreen that controls shower outlets, audio output, chromatherapy lighting, steam, and ambient lighting. It requires a separate system controller module and mounting bracket, both sold separately. The DTV+ is the most multi-sensory interface Kohler makes, designed for true spa-style shower installations.
Do smart showers work without WiFi?
Yes. Every digital shower in our roundup runs core shower functions without WiFi, including temperature control, outlet selection, and presets. What you lose without WiFi is remote start from your phone, voice assistant control via Alexa or Google, and software updates. The Kohler DTV+ in particular is designed so that core functions work without an internet connection.
Final Verdict
The best digital shower system for smart bathrooms in 2026 is the Moen Smart Water 2-Outlet Digital Thermostatic Valve (S3102) for most households. It pairs precise thermostatic control with reliable Alexa integration, holds the highest review count in our roundup, and fits inside a standard 2×4 wall. For a luxury spa-style remodel, step up to the Kohler Anthem Six-Port. For a budget-conscious first digital shower, the Kohler K-558 DTV Prompt keeps the cost low without giving up the warm-up and pause features that make smart showers worth installing.
Before you buy, confirm your rough-in valve depth, your wall cavity dimensions, and your plumber’s familiarity with the specific model. A digital shower is only as good as the install behind it, and a weekend of regret costs more than any valve on this list. If you want a broader look at non-digital options for comparison, our guide to the best digital shower systems and the related smart shower systems tested for water savings are solid next reads.
