Top 3 Product Recommendations for 2026
1. Toto Neorest NX2 – The Gold Standard
Toto continues to dominate the high-end smart toilet market, and the Neorest NX2 remains a benchmark for 2026. This model builds on Toto’s legendary reputation with a sleek, skirted design that hides all plumbing for a clean, modern look. The star feature is its “Tornado Flush” system, which uses dual nozzles to create a powerful, water-saving whirlpool that cleans the bowl without leaving streaks. The heated seat is infinitely adjustable, and the integrated bidet offers temperature-controlled water, adjustable pressure, and oscillating spray patterns for a spa-like experience.
What truly sets the NX2 apart is its “eWater+” system, which electrolyzes tap water to create a mild, non-chemical cleaning solution that sanitizes the bowl and the bidet wand after every use. This is a game-changer for hygiene-conscious users. The auto-open and close lid is responsive, and the remote control is intuitive. However, at an estimated $6,500–$7,200 (2026 pricing), it’s a significant investment. Installation requires a dedicated GFCI outlet and a water supply, but the unit is designed for DIY-friendly rough-in compatibility.
Verdict: If you want the best of the best and have the budget, the Neorest NX2 is unmatched in reliability, comfort, and hygiene. It’s the Rolls-Royce of smart toilets.
2. Kohler PureWash E930 – The Smart Home Champion
For those who prioritize smart home integration, the Kohler PureWash E930 is a standout. It works seamlessly with Amazon Alexa, Google Assistant, and Apple HomeKit, allowing you to control the bidet, seat temperature, and even the nightlight with voice commands or your phone. The “Kohler Konnect” app gives you full control and usage statistics, making it a true IoT device.
The E930 features a comfortable heated seat with multiple temperature zones, a warm air dryer, and a deodorizer. Its “Comfort Height” design matches standard chair height, making it accessible for all users. The bidet wand is self-cleaning and offers front and rear wash modes. The flush is quiet and efficient, using just 1.28 gallons per flush (GPF). Installation is straightforward, though you’ll need a nearby electrical outlet and a water line. At an estimated $1,800–$2,200 (2026 pricing), it’s a strong mid-range contender that doesn’t compromise on tech.
Verdict: Ideal for tech-savvy homeowners who want voice control and app integration. It’s a smart toilet that truly fits into a connected home ecosystem.
3. Bio Bidet Ultimate U520 – The Value Powerhouse
Bio Bidet has carved out a reputation for offering high-end features at lower price points, and the U520 is their flagship model. It includes everything you’d expect from a luxury smart toilet: a heated seat, adjustable bidet with oscillating and pulsating modes, a warm air dryer, and a deodorizer. The “Spa Seat” design is ergonomic and comfortable, even for extended use.
What makes the U520 exceptional is its “Triple Action” cleansing system, which combines a powerful flush with a fully enclosed, self-cleaning wand. The “Smart Seat” technology automatically adjusts water and seat temperature based on ambient room temperature, which is a thoughtful touch. The remote control is backlit and easy to use. Installation is similar to other models, requiring a GFCI outlet and standard water hookup. At an estimated $1,200–$1,500 (2026 pricing), it offers 90% of the features of a $6,000 Toto for a fraction of the cost.
Verdict: The best bang for your buck. If you want premium features without breaking the bank, the Bio Bidet U520 is the smart choice.

Buying Guide
Who Should Buy a Smart Toilet?
- Tech Enthusiasts: If you love controlling everything from your phone, the Kohler PureWash E930 is a no-brainer.
- Hygiene-Conscious Users: The Toto Neorest NX2’s eWater+ system is unmatched for sanitization.
- Budget-Minded Shoppers: The Bio Bidet U520 delivers luxury features without luxury pricing.
- Elderly or Mobility-Impaired Users: Heated seats, bidets, and auto-open lids reduce physical strain.
- Eco-Conscious Homeowners: Smart toilets use significantly less water per flush than traditional models (1.0–1.28 GPF vs. 1.6 GPF).
Budget Considerations
- Entry-Level ($500–$1,000): Look for bidet seat attachments or basic all-in-one units. These lack advanced features like warm air dryers or smart home integration.
- Mid-Range ($1,000–$2,500): You get heated seats, bidets, dryers, and some smart features. The Kohler PureWash E930 lives here.
- Premium ($2,500–$7,500+): Top-tier build quality, advanced hygiene systems, and premium materials. The Toto Neorest NX2 is the flagship.
Pro Tip: Factor in installation costs ($150–$400 if hiring a plumber) and potential electrical work (adding a GFCI outlet). Many models require a nearby outlet, which may not exist in older bathrooms.
Installation & Smart Home Integration
Installation Basics
- Measure Your Rough-In: The distance from the wall to the toilet flange bolts. Standard is 12 inches, but 10 or 14 inches exist. Most smart toilets are designed for 12-inch rough-ins.
- Electrical Requirements: A grounded GFCI outlet within 3–4 feet of the toilet is essential. If you don’t have one, hire a licensed electrician.
- Water Supply: A standard 1/2-inch water line is sufficient. Some models include a T-connector for easy hookup.
- Mounting: All-in-one smart toilets are typically floor-mounted, similar to traditional toilets. Follow the manufacturer’s instructions carefully.
Smart Home Integration
- Voice Control: The Kohler PureWash E930 works with Alexa, Google Assistant, and Apple HomeKit. You can say, “Alexa, start the bidet” or “Hey Google, warm the seat.”
- App Control: Kohler’s Konnect app allows scheduling, usage tracking, and remote control. Toto and Bio Bidet do not offer app integration.
- Automation: With smart home hubs, you can create routines. For example, “When I enter the bathroom (motion sensor), turn on the nightlight and warm the seat.”
- Future-Proofing: Look for models with OTA (over-the-air) firmware updates. This ensures your toilet stays current with new features.
