Bidet installations in NorCal range from simple T-adapter bidet seats (done in under an hour) to full standalone bidet fixtures requiring dedicated hot/cold supply lines and a drain connection. Electric bidet seats (e.g., TOTO Washlet, Brondell) need a nearby GFCI outlet — if one doesn't exist, we coordinate with an electrician. Our plumbers ensure all connections meet code and test for leaks before finishing.

Bidet Installation in Kerman — FAQ

Do I need a plumber for a bidet seat installation?+

Simple T-adapter bidet seats can be DIY, but hiring a plumber ensures leak-free connections and proper GFCI outlet verification. A plumber is recommended if you need a new outlet or hot water supply line.

Will a bidet seat fit my toilet?+

Most bidet seats fit standard elongated toilets. Round bowls have fewer options. We measure your toilet before ordering to confirm compatibility.

Do electric bidet seats require a dedicated circuit?+

Most bidet seats draw 1,000-1,400 watts and can share a 15A GFCI circuit if nothing else is on it. A nearby bathroom GFCI outlet within 3 feet of the toilet is ideal.
