Bidet installation cost guide

Bidets aren’t as popular here in the UK as they are in other parts of Europe. However, there are many very good reasons to have one in your bathroom.

For example, a bidet is great for boosting hygiene in the bathroom, as they offer hands-free cleaning. You can also reduce your use of toilet paper, which is better for the planet and helpful for people whose skin is irritated by toilet paper.

Here, we’ll look at the average bidet installation cost, so you can start planning and pricing your bathroom improvement project.

Costs to install a bidet

Cost itemLow costHigh costAverage cost
Professional installation - bidet£100£150£125
Douche kit/bidet shower£46£131£88.50
Toilet seat spray£19£124£71.50

First things first, you’ll need to choose a bidet for your bathroom. Depending on the style and quality, a bidet can cost between £150 and £450.

To install a bidet, you’ll need to call in a plumber or bathroom fitter with experience of fitting bidets. Experience is quite important here, as bidets are not very common in the UK and not all plumbers deal with them.

You can expect to pay around £100 and £150 for a professional fitting. However, the total bidet installation cost will depend on the complexity of the job. For example, it can cost more if new pipework or plumbing is needed.

An alternative to a bidet unit is a bidet spray fitting. This is known as a douche spray kit, but you can also find toilet seat spray attachments.

A douche is like a small, hand-held shower, which is installed within easy reach of the toilet. These can cost from £46 to £131 and can be attached to your toilet’s water tank.

A toilet seat spray can cost as little as £19 for a simple attachment, through to £124 for a replacement bidet toilet seat.

Can I install a bidet myself?

If you have the plumbing know-how, it should be relatively straightforward to install a bidet. If you’re not confident though, professional installation is recommended to avoid leaks and drips.

What’s involved in installing a bidet?

Once the mains water supply is turned off, the water and drain pipes will need to be aligned with the bidet. The bidet’s mixer/tap will need to be attached, the bidet unit bolted to the floor and all pipework properly connected. This ensures that fresh water enters the bidet and drainage water can leave, without any leaks or drips.

How much space do I need for a bidet?

You’d need to leave about as much space for a bidet as you would for a toilet. But don’t worry if you have a small bathroom, as you can go for a wall-hung bidet to save floor space. Alternatively, you can choose a bidet spray shower or toilet seat attachment – as these hardly need any extra space at all.
