Bidets are utilized to replace or supplement the standard use of toilet paper and are a widely used mode of personal hygiene throughout the world.

Knowing the plumbing requirement for a bidet related to installing and using a bidet is essential. Bidet plumbing is much like that of a traditional standard toilet.

Are you considering installing a new bidet for your home? Perhaps you like to upgrade your existing commode? Check out our best bidet converter kits buying guide to help you in that matter.

What Are the Plumbing Requirements for a Bidet?

The initial step is finding the ideal location for your bidet. Ensure there’s sufficient room in that area, as cramped space may cause plumbing and installation problems.

Here are the plumbing requirements you must consider when installing a bidet in your home. 

1. Water Supply Lines

Your main water supply line must be turned off before starting the installation. 

As mentioned earlier, determine where you want your bidet to go. Normally, that is near the toilet for utmost convenience. Once positioned, ensure the drain and water supply pipes are aligned with the bidet.

Once you are good with the location, connect the braided metal riser for both the cold and hot water supply lines. 

2. Connect the Bidet Mixer

The next stage is to secure the fixer (or the faucet) to the bidet. You can utilize the mounting hole as a guide for that to guarantee it’s properly inserted.

The washers should be threaded into the mixer’s underside to tighten it to the bidet’s body. Plumber’s putty can also be added to the mixer’s base to fasten it to the bidet more effectively once you are good with how it fits.

Next, install all the drainage components based on the manufacturer’s instruments to prevent disasters. 

3. Drill the Holes

Outline the bidet on the floor and mark where you like to place the hold-down bolts. Drill some pilot holes as your guide using a carbide-tipped drill to avoid damage to the tiles.

You will find that those drill bits will be more efficient at going through tiles. Insert the bolts once it’s done and tighten them. 

4. Make a Connection

For the last plumbing requirement, use a silicone sealant to secure the bidet’s base to the floor. That’s simple enough, as long as you ensure you eliminate the excess before it’s completely dry. You may have a difficult time doing so if you don’t. 

With your bidet ready to go, you can turn on the water and check for possible leaks. Your bathroom will have an added elegance that will offer every family member a practical, stylish addition. 

Tip: We know that you may want to install the bidet independently. However, it may help if you hire a professional plumber, especially if you are not confident in your skills. That can also help you prevent the risk of anything going wrong. 

Do I Need a Plumber to Install a Bidet? 

Do I Need a Plumber to Install a Bidet

A plumber can help and guide you throughout the installation process. They can tell what components and equipment are necessary for the task.

You don’t need to hire a plumber to install a toilet convert kit, as they are also connected to existing fixtures. But if you’re unfamiliar with plumbing, you may need to hire one, especially if you’re setting up a stand-alone bidet. 

Further, you will need a plumber if you’re setting up a stand-alone bidet as it requires:

  • cold water supply pipe before installation starts
  • hot water supply pipes
  • plumbing connections for drainage 

If there isn’t any plumbing available near your bidet, you need to install a separate supply line or drain for it. Also, you’ll like to ensure that any plumbing line extensions are properly done. 

Direct connections must be made as close as possible to the original pipe, and it should not have any fittings between them. Remember that having too many fittings could cause back pressure that can result in:

  • flanges 
  • valves
  • water leaks at joints 

Is your toilet older than 10 years? Installing a bidet may pose a problem due to the changes in shape or size during those years. It will help if you change your old toilet before installing a new one. 


Q: Should I Inform My Water Supplier of Planned Plumbing Work for My Bidet?

It’s a legal requirement to give your water supplier a hands-up when installing a bidet, especially if it has a flexible hose or ascending spray. If you have doubt, you can call a competent plumber and local water supplier.

Q: What Is Involved in Installing a Bidet?

After the main water supply is turned off, the drain and water pipes should be aligned with the bidet. The bidet’s top or mixer should be connected, and the bidet unit bolted to the floor. All pipework should also be properly connected. 

That guarantees the freshwater enters the bidet, and the drainage water can leave without drips or leaks.

Q: How Much Space Is Needed for a Bidet Installation?

You would require as much space for a bidet as for a standard toilet. But you don’t need to worry if you have a small bathroom in your house. You can still go for a wall-hung bidet to save space. 

Meanwhile, you can select a toilet seat attachment or bidet spray shower—as those hardly need added space. 

Final Thoughts

There’s no doubt that bidets are a great option for people who struggles to shower or bathe. A bidet can offer a comfortable way to wash down there without flashing up any sensitivity or making things worse

The plumbing requirements for a bidet can be a simple or complicated task, depending on the bidet type you have. The installation process can differ but normally begins with removing your toilet seat and any components in its way.
