The 1.28 GPF flush system meets WaterSense certification while maintaining strong performance through TOTO’s TORNADO FLUSH technology.

Understanding Smart Toilet Benefits

Smart toilets with bidets represent a significant upgrade from traditional bathroom fixtures in terms of both hygiene and comfort.

These devices combine automated flushing, heated seats, and precision cleansing for a complete bathroom experience.

The environmental impact is significant too, with most users reducing toilet paper consumption by 75-80%.

I calculated that our household saves approximately $45 per year on toilet paper costs.

How to Choose the Best Smart Toilet with Bidet?

Integrated Smart Toilet vs Bidet Seat Attachment

The first decision is whether to replace your entire toilet or just add a bidet seat to your existing fixture.

Integrated smart toilets like the TOTO WASHLET+ offer a seamless appearance but cost $2000-3000 and require professional installation.

Bidet seat attachments cost $150-800 and install in under an hour, but have visible hoses and power cords.

We recommend starting with a bidet seat if you’re new to the technology.

Essential Features to Prioritize

• Heated Seat: Essential for cold climates, with 3-5 temperature settings being ideal
• Warm Water Washing: Tankless heaters provide unlimited warm water versus reservoir models
• Adjustable Pressure: At least 5 settings accommodate different preferences and needs
• Self-Cleaning Nozzle: Stainless steel nozzles with EWATER+ or UV cleaning are most hygienic
• Air Dryer: Reduces toilet paper use, though premium models dry faster than budget options

Installation Requirements

All smart toilets and bidet seats require a GFCI electrical outlet within 3-4 feet of the toilet.

If you don’t have an outlet near your toilet, hiring an electrician typically costs $150-300 depending on your location.

Water supply connection uses a standard T-valve that splits from your existing toilet fill valve.

Integrated smart toilets require removing your old toilet and installing the new one, which typically costs $200-500 for professional installation.
