How to Install a Bidet (3 Different Types!)


Thinking about adding a bidet to your bathroom but unsure where to start? You’re in the right place. This guide will walk you through the installation process for three types of bidets: standalone bidets, bidet seats, and handheld bidet sprayers. We’ll break down each step to make your installation as smooth as possible.

Standalone Bidets


Standalone bidets are separate fixtures, typically placed beside your toilet. They offer a luxurious bathroom upgrade but require more space and a bit more effort to install.

Equipment / Tools Needed

  • Eye protection
  • Tape measure
  • Pencil
  • Cordless drill
  • Crescent wrench
  • Drill bits
  • Laser level (optional)

Materials Needed

  • Bidet
  • 2 3/8-inch shut-off valves
  • 2 Braided water connectors
  • Silicone sealant

Step-by-Step Guide

  1. Choose the Location
    • Ensure your bathroom has enough space for the bidet. Typically, you need a footprint of 18 inches from the wall and 16 inches side-to-side. Provide at least 8 inches of clearance on both sides.
  2. Rough-In the Water Supply Lines and Drainage
    • Measure and install the plumbing. The lines should be 6 1/2 inches above the floor or as per the manufacturer’s specifications.
    • Install 3/8-inch shut-off valves and a drain outlet at the indicated point.
  3. Install the Faucet and Drain
    • Attach the faucet and drain on the bidet fixture. Use the rubber washers and avoid over-tightening.
  4. Mark the Position of the Bidet
    • Place the bidet at the desired spot on the floor. Mark around the base and in the mounting holes with a pencil.
  5. Drill the Mounting Holes
    • Using a 3/16-inch bit, drill two holes at the marked spots. For concrete or ceramic tile floors, use a hammer drill and special tile bit.
  6. Apply the Sealant
    • Apply silicone sealant around the base of the bidet. Position the bidet over the floor bolts and rest it on the floor. Wipe away any excess sealant.
  7. Bolt Down the Bidet
    • Secure the bidet with washers and nuts using a wrench. Avoid over-tightening to prevent cracking the porcelain.
  8. Connect the Water Supply
    • Connect the water supply lines to the bidet by hand and ensure they are tight. Turn on the water and check for leaks.
  9. Test the Bidet
    • Test the bidet controls to ensure everything works properly.

Bidet Seats

Bidet seats are a convenient alternative that fit onto your existing toilet. They are less space-consuming and easier to install than standalone bidets.

Equipment / Tools Needed

  • Eye protection
  • Tape measure
  • Pencil
  • Wrench
  • Slip-joint pliers
  • Screwdriver

Materials Needed

  • Bidet seat
  • T-valve
  • Flexible water supply hose
  • Mounting bracket and bolts
  • Plumber’s tape (optional)

Step-by-Step Guide

  1. Prepare the Toilet
    • Turn off the water supply and flush the toilet to empty the tank.
    • Remove the existing toilet seat.
  2. Install the Mounting Bracket
    • Attach the mounting bracket using the provided hardware. Ensure it aligns with the bolt holes.
  3. Disconnect the Water Hose
    • Detach the water supply hose from the toilet tank. Place a towel underneath to catch any drips.
  4. Install the T-Valve
    • Connect the T-valve to the water supply valve. Attach one end of the bidet’s supply hose to the T-valve and the other end to the bidet seat.
  5. Mount the Bidet Seat
    • Slide the bidet seat onto the mounting bracket until it clicks into place. Ensure it is secure.
  6. Connect the Water Supply
    • Turn on the water supply and check for leaks. Adjust connections as necessary.
  7. Power Up the Seat
    • If your bidet seat requires electricity, plug it into a GFCI outlet. Use an extension cord if necessary.
  8. Test the Bidet Seat
    • Test all functions and settings of the bidet seat to ensure it operates correctly.
