Installation & Smart Home Integration
Installation Overview
Most smart bidet seats are designed for DIY installation, but there are a few key requirements:
- Electrical Outlet: You need a GFCI-protected outlet within 3–4 feet of the toilet. If you don’t have one, hire an electrician.
- Water Supply: A standard 1/2-inch water supply line is required. Most kits include a T-adapter.

- “Alexa, turn on the bidet seat.”
