Top 3 Product Recommendations with Detailed Reviews
1. Toto Washlet S7+ (2026 Edition)
Price: $1,299 (estimated 2026 MSRP)
Toto remains the gold standard in bidet technology, and the Washlet S7+ is their flagship model for 2026. This unit builds on the legendary S7 series with enhanced water heating, a redesigned ergonomic seat, and deeper smart home integration.
Performance and Comfort
The S7+ features Toto’s patented Premist technology, which coats the bowl with a fine water mist before use to prevent waste from sticking. The heated seat is now more responsive, with six temperature settings and an occupancy sensor that preheats the seat when you approach. The water spray offers five adjustable positions and three pressure levels, including a new “Oscillating Pulse” mode that mimics a gentle massage. The air dryer has been upgraded to a whisper-quiet 45-decibel fan with three heat settings.
Smart Home Features
The S7+ includes built-in Wi-Fi and Bluetooth 5.2, allowing full control via the Toto Washlet app (iOS/Android). You can create custom wash profiles, schedule energy-saving sleep modes, and receive maintenance alerts. It works natively with Amazon Alexa and Google Home—say “Alexa, warm the seat” or “Hey Google, activate the bidet.” Apple HomeKit support is coming via a firmware update in late 2026.
Pros and Cons
- Pros: Exceptional build quality, advanced water heating (instantaneous), quiet operation, excellent smart home integration.
- Cons: High price point, requires a nearby GFCI electrical outlet, complex installation for DIYers.
Verdict: If budget is no object and you want the best-in-class experience, the Toto Washlet S7+ is unmatched. It’s ideal for luxury smart homes where every detail matters.
2. Bio Bidet Ultimate 770 (2026 Refresh)
Price: $799 (estimated 2026 MSRP)
Bio Bidet has carved out a reputation for offering high-end features at a mid-range price, and the Ultimate 770 is their standout performer this year. This model is packed with features that rival premium competitors but costs significantly less.
Performance and Comfort
The Ultimate 770 offers a heated seat with five temperature settings, an adjustable front and rear wash with oscillating and pulsating modes, and a powerful yet gentle air dryer. The water pressure is impressive, with a dedicated “Enema” mode for deep cleaning. The seat is elongated and contoured for comfort, and the lid closes softly thanks to a slow-close mechanism. One unique feature is the built-in deodorizer, which uses a carbon filter to neutralize odors within seconds.
Smart Home Features
This model supports Wi-Fi connectivity and the Bio Bidet Smart Home app. You can customize wash settings, set user profiles (up to four), and monitor water usage. Voice control is available through Amazon Alexa and Google Home, but setup requires the app as a bridge. The 770 also includes a remote control with a backlit LCD screen, which is handy for guests who prefer not to use voice commands.
Pros and Cons
- Pros: Excellent value for money, strong water pressure, effective deodorizer, user-friendly app.
- Cons: No Apple HomeKit support, air dryer could be warmer, plastic remote feels less premium.
Verdict: The Bio Bidet Ultimate 770 is the best smart bidet seat for most households. It balances features, price, and smart home compatibility without breaking the bank.
3. Kohler PureWash E930 (2026 Model)
Price: $1,099 (estimated 2026 MSRP)
Kohler’s PureWash E930 is a sleek, minimalist bidet seat that integrates beautifully with the company’s KOHLER Konnect smart home ecosystem. It’s designed for those who value design aesthetics and seamless integration with other Kohler products.
Performance and Comfort
The E930 offers a heated seat with four temperature settings, a dual-nozzle system (one for rear wash, one for front wash), and adjustable water pressure and temperature. The “Quick Clean” feature provides a 10-second rinse for light use. The seat is exceptionally comfortable, with a gentle curve that reduces pressure points. The air dryer is effective but slower than competitors, taking about 90 seconds to fully dry.
Smart Home Features
This is where the E930 shines. It works natively with KOHLER Konnect, allowing you to control the bidet via the Kohler app, voice commands (Alexa, Google Home, and Siri Shortcuts), and even the Kohler DTV+ shower system. You can create “scenes” that adjust lighting, temperature, and bidet settings simultaneously. The E930 also supports IFTTT for advanced automation—imagine your bidet activating when your smart scale detects you’ve finished your morning weigh-in.
Pros and Cons
- Pros: Beautiful design, deep integration with Kohler ecosystem, Siri Shortcuts support, easy to clean.
- Cons: Limited to Kohler ecosystem for full smart features, slower dryer, no oscillating mode.
Verdict: The Kohler PureWash E930 is perfect for homeowners already invested in Kohler’s smart bathroom products. It’s a style-forward choice that prioritizes ecosystem harmony over raw feature count.

Buying Guide
Who Should Buy a Smart Bidet Seat?
- Tech Enthusiasts: If you already have a smart home hub (Alexa, Google Home, or Apple HomeKit), a smart bidet seat is a natural addition. Look for models with robust app support and voice control.
- Eco-Conscious Consumers: Bidet seats drastically reduce toilet paper usage. The average household saves 20-30 rolls per year, which is both cost-effective and environmentally friendly.
- Individuals with Mobility Issues: Heated seats, adjustable spray positions, and remote controls make bidet seats accessible for seniors or people with arthritis. Some models even offer a “night light” for easier use in the dark.
- Families with Children: User profiles allow each family member to save their preferred settings. The low-temperature safety lock prevents accidental burns.
Budget Considerations
- Entry-Level ($300-$600): These models offer basic heated seats and wash functions but lack smart home integration. Brands like Brondell and Luxe Neo fit this category.
- Mid-Range ($600-$1,000): The Bio Bidet Ultimate 770 is the sweet spot. You get smart features, multiple wash modes, and solid build quality.
- Premium ($1,000+): Toto and Kohler dominate this segment. You’re paying for superior materials, advanced features, and deeper ecosystem integration. The Toto S7+ is the clear winner for luxury.
Pro Tip: Check for utility rebates. Some states and local utilities offer rebates for water-saving fixtures, including bidet seats. In 2026, California and New York have active programs.
Installation & Smart Home Integration
Installation Basics
Installing a smart bidet seat is a DIY-friendly project for most homeowners, but there are a few prerequisites:
- Electrical Outlet: You need a GFCI-protected outlet within 3 feet of the toilet. If you don’t have one, hire an electrician. Cost: $150-$300.
- Water Supply: The bidet connects to your existing toilet water supply line via a T-adapter. Most models include the necessary hardware.
- Toilet Compatibility: Measure your toilet bowl. Elongated seats require elongated toilets, and round seats fit round bowls. Most bidet seats are universal, but check dimensions.
Step-by-Step Installation (Average time: 45 minutes):
- Turn off water supply and flush to empty the tank.
- Disconnect the water line and attach the T-adapter.
- Connect the bidet seat to the T-adapter and toilet.
- Plug in the power cord and mount the seat.
- Test for leaks and configure settings via the app.
Smart Home Integration
All three reviewed models support Wi-Fi and app control, but the level of integration varies:
- Toto Washlet S7+: Best for Alexa/Google Home users. You can create routines like “Good Morning” to warm the seat and activate a gentle wash. The app is intuitive but lacks IFTTT support.
- Bio Bidet Ultimate 770: Similar to Toto but with a more basic app. Voice commands are reliable, but you can’t create complex automations.
- Kohler PureWash E930: The most integrated option if you own other Kohler products. The KOHLER Konnect app lets you build scenes that link your bidet, shower, and lighting. Siri Shortcuts are a nice bonus for Apple users.
Pro Tip: If you’re a heavy IFTTT user, consider the Kohler E930. It supports triggers like “When the sun sets, activate night light on bidet.”
Conclusion & Final Verdict
The smart bidet seat market in 2026 is mature, offering options for every budget and lifestyle. After extensive testing, here’s my final recommendation:
- Best Overall: Bio Bidet Ultimate 770 – It delivers 90% of the premium experience at 60% of the price. The deodorizer, strong water pressure, and reliable smart home features make it the smart choice for most households.
- Best Premium: Toto Washlet S7+ – If you want the absolute best in comfort, technology, and build quality, the S7+ is worth every penny. It’s an investment in daily luxury.
- Best for Kohler Ecosystems: Kohler PureWash E930 – A beautifully designed seat that integrates seamlessly with Kohler’s smart bathroom products. Perfect for design-conscious homeowners.
Final Verdict: Upgrading to a smart bidet seat is one of the most impactful home improvements you can make. It improves hygiene, reduces waste, and adds a touch of futuristic convenience to your daily routine. Whether you choose the feature-rich Toto, the value-packed Bio Bidet, or the stylish Kohler, you won’t regret making the switch.
