Is a bidet spray legal in the UK?
Yes. A handheld bidet spray is legal in the UK, but it must be installed so it cannot contaminate the drinking water supply. That is what the rules are about.
Under the Water Supply (Water Fittings) Regulations 1999, a spray on a hose that can reach into the toilet pan is treated as a high backflow risk, known as fluid category 5. Backflow is when water flows the wrong way, back into the supply pipes. If a spray head was left in the pan and the mains pressure dropped, dirty water could be drawn back towards the pipes that feed your kitchen tap.
To prevent this, the spray needs the right backflow protection for the product and setup. Some kits sold online come with little more than a hose and a tap connector, which may not be enough on their own. Before you buy, send us a link or photo and we will advise which products comply. WRAS (the Water Regulations Advisory Scheme) approves fittings that meet the regulations, so WRAS-approved or regulation-compliant products and arrangements are the safest route.
What types of bidet spray can be fitted?
The most common choice is a handheld spray, or shattaf, on a hose next to the toilet. There are also options that sit under the seat or replace it.
Bidet sprays are common in many Leicester homes, and more people add one when they update a bathroom. Which type suits you depends on the space, the toilet and whether you want warm water:
- Handheld spray (shattaf)
- A spray head on a flexible hose, with a valve and wall holster beside the toilet.
- Bidet attachment under the seat
- A slim unit fitted between the pan and seat, with a nozzle and side control.
- Combined bidet toilet seat
- A replacement seat with a built-in wash. Some models need a power supply nearby.
- Handheld spray with a thermostatic mixer
- Delivers warm water at a steady, safe temperature.
Can a bidet spray have warm water?
Yes, if it is connected through a thermostatic mixer rather than to the cold pipe alone. Cold-only is simpler to fit, and many people are happy with it.
A thermostatic mixer blends hot and cold water to a set temperature and stops it getting too hot. That matters for a spray used on the body, especially for children or older relatives. To fit one, we need a hot water pipe close enough to reach. In a small cloakroom with only a cold supply, warm water may mean running a new hot pipe, which adds to the price. Your photos show us what is possible before you decide.
Why does a bidet spray need its own shut-off valve?
So the hose is not under mains pressure all the time. Turning the valve off after use takes the strain off the hose and spray head, which lowers the risk of a slow leak or a burst.
A handheld spray sits on a flexible hose that gets moved, twisted and dropped many times a day. Hoses that stay pressurised around the clock are more likely to weep or split over time, often behind the toilet where you will not see it straight away. A small quarter-turn valve within easy reach makes switching it off a habit rather than a chore. It also lets you change a worn spray head or hose without turning off the water to the whole house.
Where should the bidet spray holder go?
Within easy reach from the seat, usually on the wall beside the cistern. The hose should hang without kinking, and the spray head should not rest inside the pan when it is put away.
We look at which hand you use, how close the wall is and where the pipework runs. Then we plan the neatest layout:
- Holster height and side
- Set where you can reach it without twisting.
- Hose length
- Long enough to use comfortably, without trailing on the floor.
- Hidden pipework
- Run behind the toilet or inside boxing where possible, not across the wall.
- Valve position
- Easy to reach, so turning it off after use becomes routine.
- Tiles
- Drilled with care, with fixings sealed to keep water out.
What photos do I need to send for a bidet spray quote?
A few clear phone photos are usually enough for us to give you a fixed price. Take them in good light, and include one wide shot so we can see the whole room.
The photos that help most are:
- The whole toilet and the wall beside it
- Shows where the holster and valve can go.
- Pipework below and behind the cistern
- Shows where we can connect to the water supply.
- Any hot water pipe nearby
- Needed if you want warm water through a mixer.
- The kit you have bought, if any
- A photo of the box or a product link lets us check it complies.
How do I stop limescale blocking a bidet spray head?
Clean the spray head regularly and soak it in descaler when the flow starts to weaken. Leicester has hard to very hard water, so limescale builds up faster here than in many parts of the country.
Scale blocks the small holes in the spray head, which makes the jet weak or uneven. Rubbing the nozzles with your thumb every few days helps. Every month or two, unscrew the head and soak it in a vinegar or descaler solution, following the maker's instructions. A spray head with soft rubber nozzles is easier to keep clear. If the head is badly scaled or the hose has started to weep, a replacement is often the simplest answer.
