Adding a bidet to your bathroom will add an aesthetic yet practical feature that will instantly elevate your bathroom design. Bidets will help to make your bathroom routine much more hygienic and installing one in your bathroom will make your bathroom feel more luxurious. 

But when it comes to installation, adding one to your bathroom is easier than you think! Installing a bidet can seem overwhelming at first, but by following the steps below, you will be able to successfully install your new bidet all by yourself!


Installing a Bidet

We recommend that you only attempt to install a bidet yourself if you are confident with your DIY and basic plumbing skills. Otherwise, we recommend hiring a professional to install one for you!


1. Water Supply

Before you start to install your new bidet, make sure that you have turned off your main water supply, otherwise you will be left with a big mess which could cause a lot of damage in your bathroom.

The first thing you will need to do is decide where you are going to place your bidet, this is usually placed next to the toilet for convenience. Once you know where you are going to install your bidet, you can have the new water supply pipes for the bidet installed.


2. Position The Bidet

Once you have water supply pipes installed for your bidet, you can start to install your new bidet. When positioning the bidet, make sure that the water supply and drain pipes are correctly aligned with the bidet. Once you’re happy with the placement, attach a braided metal riser for both the hot and cold supply lines.


3. Attach Bidet Mixer

The next step is to secure the bidet mixer at the tap mounting hole on the bidet. To secure the tap, the washers should be threaded underneath the mixer to ensure that it is fitted tightly against the bidet.

For extra sturdiness, you can add some plumber’s putty which will make the tap fasten to the bidet base much more effectively.


4. Drill Holes

Now you can drill the holes that will secure the bidet in place. If you are adding a floor standing bidet to your bathroom, you can draw an outline of the bidet on the floor and mark out where the hold-down bolts will be placed. Carefully drill some pilot holes as a guide, using a good quality carbide-tipped drill to prevent any damage to your tiles.

You’ll find that these drill bits will be much more effective at going through tiles. Once this is done, insert the hold-down bolts and tighten them.


5. Connect Pipes 

Now you want to make sure that everything is connected properly. Attach the hot and cold water supply risers to their correct positions. These should first be hand tightened thoroughly before being further tightened with a wrench to make sure they are fully secured.

With this done you can install the P trap. This is an integral aspect as it allows for effective drainage. Make sure it is fitted the correct way around, and attach one end to the drain tailpipe and the other to your drain line and tighten fully to prevent any leaking.


6. Sealing

With the bidet in place, you can go in with some silicone sealant to secure the base of the bidet to the floor. This is easy enough, as long as you make sure you remove any excess before it is allowed to try as you may struggle with this later if you don’t.

Then, you can turn on the main water supply and check for any leaks before you start to use your new bidet. If there are no leaks present, you are done! You can now use your bidet and make your bathroom routine much more hygienic.
