Top 3 Product Recommendations
1. Toto S550e Washlet+ (Best Overall)
Price: $1,049 (2026 MSRP)
Rating: 4.8/5
The Toto S550e Washlet+ is the gold standard for smart bidet seats, and for good reason. Toto has been perfecting the bidet experience for decades, and the S550e represents the pinnacle of their engineering. This elongated seat features Toto’s proprietary EWATER+ system, which uses electrolyzed water to clean the bowl and nozzle, reducing the need for harsh chemicals. The heated seat offers multiple temperature settings, and the warm air dryer is surprisingly powerful, drying you completely in under a minute.
Performance: The S550e’s oscillating and pulsating spray patterns are a game-changer. The front and rear wash modes are customizable with five pressure settings and five temperature settings. The “Soft Wash” mode is gentle enough for sensitive skin, while the “Power Wash” provides a deep clean. The seat automatically opens and closes with a motion sensor, and the remote control is intuitive with backlit buttons.
Smart Features: This bidet seat integrates seamlessly with Amazon Alexa and Google Assistant, allowing voice commands like “Alexa, turn on the heated seat” or “Hey Google, start the bidet.” The Toto Washlet+ app lets you create user profiles, set schedules, and monitor water usage. Installation is straightforward for a DIYer with basic plumbing skills, though professional installation is recommended for the water supply connection.
Pros: Premium build quality, excellent cleaning performance, robust smart home integration, self-cleaning nozzle
Cons: High price point, requires a nearby electrical outlet, elongated seat only
2. Bio Bidet BB-2000 (Best Value)
Price: $599 (2026 MSRP)
Rating: 4.6/5
If you want luxury features without breaking the bank, the Bio Bidet BB-2000 is your best bet. This sleek, elongated seat offers heated seat, warm water wash, and a warm air dryer, all controlled via a wireless remote. The BB-2000’s standout feature is its “Enema Wash” mode, which provides a high-pressure stream for thorough cleaning—ideal for those with digestive issues or post-surgery needs.
Performance: The dual stainless steel nozzles (one for rear wash, one for front wash) are self-cleaning and retract automatically after each use. The water pressure has 10 levels, and the water temperature has 6 levels, giving you granular control. The seat is ergonomically designed with a slow-close lid, and the heated seat is adjustable from 86°F to 104°F. The dryer is effective but takes about 90 seconds for a full dry.
Smart Features: While the BB-2000 lacks voice control, it does include a nightlight that illuminates the bowl in soft blue light—a surprisingly useful feature for nighttime bathroom trips. The remote control is wall-mountable and has a magnetic holder. There’s no app integration, but the unit is compatible with most standard toilets (elongated only) and installs in under an hour.
Pros: Excellent value for money, powerful wash modes, easy installation, durable build
Cons: No voice control or app, elongated fit only, dryer could be faster
3. Kohler PureWash E930 (Best for Smart Home Integration)
Price: $1,299 (2026 MSRP)
Rating: 4.7/5
Kohler’s PureWash E930 is a masterpiece of design and technology, targeting the discerning homeowner who wants their bathroom to be a fully connected sanctuary. This bidet seat features a heated seat, warm water wash, and a powerful dryer, but its real strength lies in its integration with Kohler’s Konnect smart home platform. The E930 also includes a built-in deodorizer that uses a carbon filter to neutralize odors instantly.
Performance: The “Pre-Mist” function sprays the bowl with water before use to prevent waste from sticking, reducing the need for scrubbing. The wash modes include “Rear Wash,” “Front Wash,” “Oscillating Wash,” and “Massage Wash,” all with adjustable pressure and temperature. The seat is heated and has a “Sit & Wait” feature that keeps the seat warm for up to 8 hours after your last use. The dryer is the quietest on the market, operating at just 45 decibels.
Smart Features: The PureWash E930 works with Amazon Alexa, Google Assistant, and Apple HomeKit. You can set personalized presets for multiple users, schedule the heated seat to turn on before your morning routine, and even receive maintenance alerts via the Kohler Konnect app. The remote control is sleek and waterproof, and the unit has a “Nightlight” mode with customizable colors.
Pros: Superior smart home integration (HomeKit support), quiet operation, Pre-Mist function, excellent odor control
Cons: Very expensive, requires professional installation for water and electrical, some users find the seat firm

Buying Guide
Who Should Buy a Smart Bidet Seat?
Smart bidet seats are ideal for a wide range of users:
- Tech Enthusiasts: If you already have smart lights, thermostats, and speakers, adding a bidet seat with voice control completes your smart home ecosystem.
- Health-Conscious Individuals: Bidets provide a more thorough clean than toilet paper, reducing irritation and the risk of infections. They’re especially beneficial for those with hemorrhoids, IBS, or post-surgery recovery.
- Eco-Conscious Homeowners: Bidets significantly reduce toilet paper usage, saving trees, water (in production), and landfill waste. The Toto S550e’s EWATER+ system also reduces the need for chemical cleaners.
- Families with Multiple Users: Models with user profiles (like the Toto S550e and Kohler E930) allow each family member to save their preferred settings.
- Elderly or Mobility-Challenged Users: Heated seats, remote controls, and hands-free operation make bathroom visits safer and more comfortable.
Budget Considerations
- Entry-Level ($200–$400): Basic models with cold water only or limited features. Brands like Luxe Neo and Brondell offer reliable options, but expect no smart features.
- Mid-Range ($400–$800): The sweet spot for most buyers. The Bio Bidet BB-2000 falls here, offering heated seat, warm water, and dryer. Some models may include basic remote controls.
- Premium ($800–$1,500+): High-end models like the Toto S550e and Kohler PureWash E930 include voice control, app integration, advanced wash modes, and superior build quality. Expect longer warranties and better customer support.
Hidden Costs: Factor in installation costs if you’re not handy (professional installation typically runs $150–$300) and potential electrical work if no outlet is near your toilet.
Installation & Smart Home Integration
Installation Overview
Installing a smart bidet seat is a DIY-friendly project for most homeowners, but preparation is key.
What You’ll Need:
- A nearby electrical outlet (GFCI-protected is recommended)
- A standard toilet with an elongated bowl (most bidet seats only fit elongated toilets)
- Basic tools: adjustable wrench, screwdriver, and a bucket (to catch water)
Step-by-Step:
- Turn off the water supply valve behind the toilet and flush to empty the tank.
- Remove the existing toilet seat and install the bidet mounting plate using the provided hardware.
- Connect the T-adapter to the water supply line and attach the bidet’s water hose.
- Plug the bidet into the electrical outlet and snap the seat onto the mounting plate.
- Turn the water back on, check for leaks, and test the functions.
Pro Tip: If you’re uncomfortable with plumbing or electrical work, hire a licensed plumber or electrician. Many brands offer professional installation services through third-party providers.
Smart Home Integration
The real magic of a smart bidet seat lies in its ability to integrate with your existing smart home setup.
- Voice Control: Both the Toto S550e and Kohler PureWash E930 work with Amazon Alexa and Google Assistant. You can create routines like “Good morning” to turn on the heated seat and start the bidet at a preset temperature.
- App Control: The Toto Washlet+ app and Kohler Konnect app allow remote control, user profiles, and usage tracking. The Kohler app is particularly robust, offering maintenance alerts and integration with other Kohler products.
- Apple HomeKit: The Kohler PureWash E930 is one of the few bidet seats with HomeKit support, enabling Siri voice control and integration with your HomeKit scenes.
- IFTTT Compatibility: Toto and Kohler both support IFTTT, allowing advanced automations like “If the bathroom humidity sensor detects moisture, turn on the bidet fan.”
Note: The Bio Bidet BB-2000 lacks smart home integration, making it a better choice for those who prioritize value over connectivity.
