Will it fit my UK toilet?

A bidet attachment will fit most UK toilets if:

• Your toilet seat uses a standard 2-bolt mounting
• You can access the water supply at the cistern (standard shut-off/valve area)
• You’re using a standard UK water connection (1/2″ – included)

May not be suitable if:

• You have a fully concealed cistern with no access to the water supply (may require extra installation effort)
• You want warm water / heated seat features (this is non-electric, cold water)

“No plumbing” — what that really means

Most customers install an under-seat bidet attachment without a plumber because you’re not changing the toilet — you’re simply adding a T-valve and hose to the existing water feed.

Typical install steps

1. Turn off water at the valve
2. Connect the included UK 1/2″ T-valve
3. Attach the hose to the bidet unit
4. Mount the unit under your seat
5. Turn water on and test

What a bidet attachment is NOT

To avoid buying the wrong thing:

• Not a replacement toilet seat
• Not an electric bidet seat (no heating / dryer)
• Not a handheld sprayer / “bum gun”

It’s an under-seat attachment that adds a targeted wash using your existing water supply.
