Using the toilet after unloading yourself could sometimes be tricky. If you are especially OC about hygiene, you should consider everything around you.

Your toilet amenities represent your priorities for comfort, easy use, and functional aesthetics. Among these, the bidet is something special.

For hygiene purposes, the bidet is indispensable in your modern lifestyle. These steps provide you with ideas on how to install a bidet toilet seat.

Bidet Toilet Seat Installation Steps

The following steps are advised when installing a bidet toilet seat. Take a read if you just installed one the first time.

Step 1: Prepare your toilet for the new bidet toilet seat

This may appear obvious but cleaning the toilet bowl well, including its seat and undersides, are essential for a very important reason: hygiene.

If you have an existing toilet seat installed, remove it first to expose all areas needing cleaning.

Use a brush and toilet bowl cleaner or muriatic acid to remove limescale deposits on areas usually hidden and where watermarks appear.

Remove all stains and discolorations in crevices and hidden areas if possible. Your new bidet toilet seat looks best with a neat, shiny bowl.

With a rag or towel, dry your toilet’s cleaned surfaces, especially its seat.

Step 2: Unpack the new toilet bidet seat

Before installing your new bidet toilet seat, read the accompanying instruction manual carefully. This should give you head-up ideas.

Remove any plastic protection cover of the new set, if there is any. Carefully unpack its supplied screws, mounting plate, and other attachments.

To ensure that your new bidet set fits well with your bowl, try placing it on the seat and determining its fitness before getting down to work.

Step 3: Install your new bidet toilet seat

  1. Shut the water supply valve off before flushing your toilet. Remove the hose connector from the water tank.
  2. Before attaching the supplied T-valve to the tank inlet, put Teflon tape on the thread. This ensures leak-free connection of the water supply to the tank and the bidet seat.
  3. With your screwdriver, mount the toilet seat bracket or plate following the instructions in the manual. Attach the new bidet toilet seat in place.
  4. Reconnect the water supply hose to the T-valve. Connect the new bidet toilet seat to the T-valve using the supplied hose.
  5. After hooking up your bidet toilet seat, test your installation for proper operation. Use a small basin or pail to deflect the water squirting out.
  • Note: If you install an electric bidet seat, make sure you locate a GFCI outlet and plug it in before using it.
