Buying Guide
Who Should Buy a Smart Toilet?
- Tech Enthusiasts: If you love automating every room, a smart toilet with app control and health tracking (like the TOTO Neorest NX2) is a must-have.
- Families with Small Children: The Kohler PureWash E930’s soft-close seat and dual-flush are safer and more water-efficient.
- Elderly or Disabled Individuals: Heated seats, bidets, and auto-open lids reduce physical strain. The BioBidet Flow X2 offers basic comfort at an affordable price.
- First-Time Buyers: Start with the BioBidet Flow X2 to dip your toes—you can always upgrade later.
Budget Considerations
- Under $1,000: Stick with BioBidet or a similar budget model. You’ll get a heated seat and bidet, but no smart features.
- $1,500–$3,000: This sweet spot offers excellent quality (Kohler, American Standard, TOTO’s mid-range). You’ll get app control and self-cleaning.
- Over $5,000: Premium models like the TOTO Neorest NX2 offer health monitoring, advanced self-cleaning, and best-in-class comfort. Only buy if you plan to stay in your home for 10+ years.
Installation Considerations
- Rough-in Measurement: Standard US toilets require a 12-inch rough-in (distance from wall to bolt centers). Measure yours before buying—10- and 14-inch options are less common.
- Electrical Outlet: Most smart toilets need a nearby 120V outlet. If you don’t have one, factor in an electrician’s cost ($150–$400) to add one.
- Water Supply: A standard 3/8-inch compression fitting works for most models. Some high-end units require a 1/2-inch supply.
Installation & Smart Home Integration
Installation Tips
- DIY vs. Professional: Models under $1,500 (like the BioBidet Flow X2) are usually DIY-friendly—just follow the manual and use a wax ring. For premium models with complex electronics, hire a licensed plumber ($200–$500).
- Check Your Floor: Smart toilets are heavier than standard ones (up to 100 lbs). Ensure your floor can support the weight, especially for tile or vinyl.
- Smart Home Setup:
- TOTO Neorest NX2: Syncs via Wi-Fi to the TOTO Wellness app. Works with Alexa for voice commands like “Alexa, warm the seat.”
- Kohler PureWash E930: Uses Kohler Konnect, which integrates with Google Home and Alexa. You can create routines (e.g., “Good morning” triggers seat warming and nightlight off).
- BioBidet Flow X2: No smart home integration—good for those who prefer simplicity.
Integration Challenges
- Wi-Fi Interference: Bathrooms with thick walls may need a Wi-Fi extender for reliable app control.
- Power Outages: Most smart toilets have a manual flush override, but bidet and seat heating won’t work without power. Consider a backup battery for high-end models.
- Privacy: Health data syncs to the cloud. Ensure the manufacturer offers encryption—TOTO and Kohler both use 256-bit AES.
Conclusion & Final Verdict
The smart toilet market in 2026 has matured to offer something for everyone—from the budget-conscious to the luxury seeker. After extensive testing, here’s my final recommendation:
- Best Overall: TOTO Neorest NX2 – If you have the budget, it’s the most comfortable, hygienic, and feature-rich smart toilet on the market. The health monitoring is a game-changer for proactive wellness.
- Best Value: Kohler PureWash E930 – It delivers 85% of the premium experience at 35% of the cost. Perfect for families and tech-savvy homeowners who want app control and reliable performance.
- Best Budget: BioBidet Flow X2 – An excellent entry-level smart toilet that doesn’t skimp on essentials like a heated seat and bidet. Ideal for renters or those new to smart bathrooms.
Final Verdict: Don’t overthink it—if you can afford the Kohler PureWash E930, buy it. It’s the sweet spot for 2026. But if health tracking is your priority, the TOTO Neorest NX2 is worth every penny. And if you’re just starting out, the BioBidet Flow X2 will make you wonder why you waited so long to upgrade.
Your bathroom is about to get a lot smarter. Choose wisely, and enjoy the flush.
