How to install a bidet seat – 5 Simple Steps

Bidet seats are a great way to upgrade your toilet to a bidet toilet without having to remove the whole unit.  You save money and you save the hassle of having to take out and install a new toilet.

Installing a bidet seat is very simple.  You don’t need any fancy tools other than a screwdriver and wrench.  When you purchase a bidet seat it would already come with all the parts (like a t-adapter) that you will need to install the bidet.  It would also come with some instructions.  But here, we’ll teach you how to install a bidet seat in 5 simple steps.

Step 1 – Remove your old toilet seat.  You can do this by unscrewing the bolts on your existing toilet seat.

Step 2 – Connect the water source.  First, shut off the water supply to your toilet.  You can do this by turning the shut off valve located next to your toilet.  Once you turn the water supply off, drain the toilet tank completely by flushing.  Then disconnect the toilet tank supply hose.

Attach the T-valve that you got with your bidet seat with the toilet tank supply hose and the bidet seat supply hose.  This T-valve will divert water between the toilet tank and bidet spray.  The bidet seat supply hose would attach to the T-valve on the side, and the toilet tank supply hose would attach to the T-valve on the top.  It should look something like this:

Step 3 – Install the mounting plate.  The method of installation will vary slightly between bidet seats, but here you are fastening the mounting plate for the bidet seat to the toilet.  The bidet seat will then slide onto the mounting plate.  This is what the mounting plate should look like after installation:

Step 4 – Attach the seat.  After you attach the seat you can plug it into your electric outlet and turn the water supply back on.

Step 5 – Check for leaks.  Make sure that the supply hoses are not leaking.  Tighten any loose parts if necessary.

If you don’t already have a ground-fault circuit interrupter outlet near your toilet to plug in the bidet seat, you will have to install one.  Consider hiring an electrician to do the job.
