Here’s how to install a bidet toilet seat:

- turn off the water supply to your toilet.
- install the t-valve in your existing toilet supply line. </li
- mount bidet toilet seat to toilet.

see below for more detailed instructions.
first, remove the old toilet seat:
- The seat will be attached to the rim with a couple of large mounting bolts. There may be little plastic covers over the tops of these bolts, so you’ll need to pry them open with a flathead screwdriver.
- Once you can access the tops of the bolts, use your screwdriver to remove them. you may need to reach under the toilet to unscrew the nuts that hold them in place. the mounting bolts on some toilet seats are actually part of the seat itself and have no “top” to unscrew. however, these seats should still have a couple of nuts under the rim, so you should be able to unscrew them and free the seat.
- once the nuts and bolts are removed, lift the seat up and It should be nicely off. clean the rim to prepare it for your new bidet seat. some bidet devices, like tushy, use the existing toilet seat, so don’t throw it away.
then turn off the water supply to your toilet:
- To locate the toilet shutoff valve, look behind the toilet, near the floor. a supply hose should run from the bottom of the toilet tank to a water supply pipe in the wall, connected by an oval-shaped valve. this is your toilet shutoff valve.
- turn the toilet shutoff valve clockwise until it stops.
- flush the toilet to drain the remaining water in the tank.
Install the t-valve into your toilet’s existing supply line:
- Included with your new bidet seat should be a tee valve, called a “tee valve”. this will divert the water between the toilet and the bidet sprayer. Most of the components in this step should be made of plastic, so hand-tightening them should be all you need to get them a snug fit. use your wrench on any metal fittings you are having trouble tightening.
- unscrew the supply hose from the bottom of the toilet tank. A small amount of water left in the tank could leak, so have a bucket and towel handy.
- Connect the tee valve to the bottom of the toilet tank where the supply hose was connected. </li
- reconnect the supply hose to the bottom of the t-valve.
mount the toilet seat with bidet on the toilet:
- Included with the bidet seat there should be a flat plastic mounting plate. Attach this mounting plate to the back of the rim, lining it up with the existing bolt holes. if you are installing a bidet device like the tushy, the entire unit is one mounting plate.
- insert the included mounting bolts through the bolt holes and secure in place with their nuts under the edge. Depending on the seat of your bidet, these nuts and bolts may be metal instead of plastic. if so, use your wrench and/or screwdriver.
- slide the bidet seat onto the mounting plate, toward the back of the toilet, until it snaps into place.
connect the bidet seat to the water supply:
- Your bidet seat will have its own water supply hose. connect one end of this hose to the remaining opening of the t-valve.
- connect the other end of the bidet hose to the connection on the side of the bidet seat. double check that all hose connections are tight. you are now ready to open the shutoff valve you closed earlier.
- open the toilet shutoff valve by turning it counterclockwise. this will fill the toilet tank and supply the bidet seat with the water it needs to function. check for leaks and tighten hose connections if necessary.
- if you have an electronic bidet seat, plug it into a grounded gfci outlet (these are designed to prevent accidental electrical shock and are usually found in the home). bathrooms and kitchens). if no outlet is within reach, use an extension cord.
