Buying Guide
Who Should Buy a Smart Toilet?
- Tech Enthusiasts: If you already have a smart home hub and enjoy automating everything, a smart toilet is the next logical step. The BioBidet Flow 9000’s Matter compatibility makes it ideal for this group.
- Health-Conscious Individuals: The Toto Neorest NX2’s health monitoring can provide valuable data for those tracking wellness metrics.
- Elderly or Mobility-Challenged Users: Features like heated seats, automatic open/close, and bidet functions significantly improve bathroom accessibility.
- Eco-Conscious Homeowners: Smart toilets use less water than traditional models, and many offer water usage tracking.
Budget Considerations
- Under $1,500: Stick with a high-quality bidet seat like the Kohler PureWash E930. You get most smart features without replacing your toilet.
- $2,000 – $3,500: This sweet spot offers full smart toilets with excellent features. The BioBidet Flow 9000 is the best value here.
- Over $5,000: Luxury models like the Toto Neorest NX2 offer premium materials, health monitoring, and the best warranty. Only consider this if you have a high budget and want the absolute best.
Installation Considerations
- Power Source: Smart toilets require a nearby electrical outlet (GFCI protected). If you don’t have one, factor in the cost of hiring an electrician ($150–$300).
- Plumbing: Most smart toilets use standard 12-inch rough-in measurements. Measure your existing toilet’s rough-in before purchasing.
- DIY vs. Professional: Bidet seats are generally DIY-friendly. Full smart toilets often require a plumber for proper installation and calibration.
Installation & Smart Home Integration
Installation Tips
- Check Your Rough-In: Measure from the wall to the center of the toilet flange. Standard is 12 inches, but 10-inch and 14-inch options exist.
- Electrical Requirements: Ensure you have a GFCI outlet within 3 feet of the toilet. If not, hire a licensed electrician.
- Water Supply: Most smart toilets use a standard 3/8-inch compression fitting. Check the manufacturer’s specifications.
- Floor Reinforcement: Some luxury models are heavy (over 100 lbs). Ensure your bathroom floor can support the weight.
Smart Home Integration
- Voice Control: All three recommended models work with Alexa and Google Assistant. Use commands like “Alexa, flush the toilet” or “Hey Google, warm the seat.”
- Routines: Create morning routines that trigger the toilet to preheat the seat and activate the bidet at a specific time.
- Health Data Integration: The Toto Neorest NX2 can sync health data with Apple Health and Google Fit, allowing you to track trends over time.
- Matter Protocol: The BioBidet Flow 9000 supports Matter, making it compatible with future smart home ecosystems. This is a future-proof choice.
Common Integration Issues
- Wi-Fi Connectivity: Some models struggle with weak Wi-Fi signals in bathrooms. Use a mesh network or Wi-Fi extender.
- App Updates: Keep the toilet’s firmware updated for optimal performance and security.
- Privacy Concerns: Health monitoring data is stored locally or encrypted. Review the privacy policy before purchasing.
