How to Install a Bidet Seat

A cold-water bidet seat installs in 20 minutes; warm-water versions need a nearby GFCI outlet and a warm-water tee.

Common causes

• No electrical outlet within reach
• No warm-water source at the toilet
• Odd toilet shape (French curve, D-shape)
• Non-standard bolt spacing

Step-by-step

1. 01Shut off the toilet supply and drain the tank
2. 02Remove the existing seat and install the bidet mounting plate
3. 03Install the tee on the supply line — warm-water tee if applicable
4. 04Plug into a GFCI outlet and test at low flow first

When to call Northbridge

• No GFCI outlet near the toilet
• Warm-water tee requires new tubing to the vanity
• Toilet bowl shape isn't standard round or elongated
• Multiple units for the whole house
