Having a bidet in your bathroom is a dream for many homeowners, but having one professionally installed can really put a dent in your wallet. Fortunately, you can install a bidet seat without any previous plumbing experience. Here's a quick guide on how to install a bidet in your bathroom without breaking your budget.

Step 1 - Choosing A Bidet System

There are three popular types of bidets on the market. The first option is an actual toilet seat that features bidet functionality. The second variety attaches to the existing toilet seat while the third is a handheld bidet sprayer that is installed near the toilet. A bidet seat usually runs around $300, while the add-on varieties are usually well under $200. All three types of bidets connect to the toilet's water line and are reasonably easy to install.

Step 2 - Cut Off Water

You need to turn off the water supply to the toilet before you install the bidet seat. There should be a main water supply valve located somewhere inside your home. If you cannot find the valve, you can always turn off the water at the street level as well. Once the water is off, flush the toilet to remove water from the tank and the bowl

Step 3 - Remove Old Seat

The new bidet seat will replace the old unit in its entirety. Remove the old seat by unscrewing the bolts holding it in place. These are usually hidden underneath a plastic tab. Once the old seat if off, clean the area to ensure a smooth installation of the bidet unit. Side note: If the bolts do not run through the toilet, you will need to purchase a top mount system to install the bidet.

Step 4 - Install Mounting Plate

With the old seat off, it is time to install a mounting plate for the new system. The mounting plate should be installed over the old screw holds, so make sure everything lines up before you tighten the bolts. If everything is correct, secure the plate in place before proceeding to the next step.

Step 5 - Attach The Bidet Seat

Once the mounting plate is in place, line up the bidet seat and click it into position. The mounting plate should have adjustable screws that enable you to line up the seat with the toilet. You may have to make several adjustments to get it to fit just right. You can also sit on the unit to make sure everything is aligned properly.

Step 6 - Water Supply Connection

Locate the flexible water hose near your toilet and disconnect it from the toilet unit. Do not unscrew the hose at the main valve. You can expect some leakage from the hose, but not too much. You can clean up any excess water with a clean towel. If the hose does not stop leaking, then the main water valve shut-off needs to be tightened a little more.

Step 7 - Install New Bidet Valve

Near the tank of the toilet, attach the bidet t-valve that should have come with the unit. Then attach the flexible water hose to the bottom of the new valve. Once the main water supply is in place, screw in the bidet's water supply line at the t-valve. The other end of the hose should be attached to the bidet if it is not already in place. Double check that all of the hoses are nice and tight.

Step 8 - Test Your New Bidet

With everything properly connected, it is time to test the bidet. Turn on the main water supply and inspect each hose for signs of leaks. If that checks out, test the bidet seat to make sure it is functioning properly. Most bidet seats have a special sensor that requires you to sit on it before it works. This is a safety featured to prevent any accidental discharges when nobody is in the bathroom.

Tips & Tricks

Use plumber's tape when connecting the hoses. The tape will help seal the connection and prevent future leaks. If the bidet seat comes equipped with electronic functions, make sure plug it into a GFI outlet. You may need to purchase an extension cord if an outlet is out of reach. When testing the bidet, you can usually get around the safety feature by placing your hand in contact with the seat. Just make sure you cover the nozzle with a towel or your hand to prevent getting sprayed.
