The complete guide
Buying Guide
There are three ways to put a bidet on a toilet you already own, and the choice usually comes down to whether there is a plug socket next to it.
A handheld sprayer is the cheapest and most flexible, but you aim it. An electric seat does everything, including warm water and warm air, but it replaces the seat and needs power within reach, which a great many European bathrooms do not have.
This sits in the middle.
What it actually is
A thin panel that lives between your toilet pan and your existing seat.
You unbolt the seat, lay the panel on the pan, and bolt the seat back on top. The nozzle sits tucked at the back and swings out under the bowl when you turn the dial, then retracts when you turn it off.
Nothing about your toilet is permanently changed, and the whole thing comes off again if you move.
Reading the materials list
This category is full of products that are moulded plastic from end to end, so the specification is worth going through.
The housing is ABS, which is the standard and sensible choice for a moulded bathroom part. The adapter is brass. The hose is braided steel rather than plastic. The valve cores are metal and ceramic.
That last one is the detail. Ceramic discs are what modern taps use, and they are the reason a tap still shuts off cleanly after five years instead of weeping. On a fitting that holds mains pressure permanently, it is the difference between one that lasts and one that starts dripping into the pan.
Fitting it
The same arrangement as our handheld sprayers. Close the isolator under the cistern, put the brass T between the flexible supply and the cistern inlet, and run the braided hose along to the panel.
Nothing is cut. Nothing is permanent. Allow half an hour, most of which is the seat.
The water is cold
Worth saying plainly rather than leaving you to find out.
It comes from the same cold feed that fills your cistern, because that is the only water there is at a toilet. Plenty of people find that completely fine and stop noticing after a week. Some people do not, particularly in winter.
If warm water is the thing you actually want, the product that provides it is an electric bidet seat, and it needs a socket.
Cleaning it
Wipe the nozzle area when you clean the toilet. The one thing to avoid is bleach and thick cleaners sitting directly on the plastic housing, because strong cleaners dull ABS over time and the housing is the part you look at.
In hard water, a wipe with a descaler on a cloth keeps the nozzle holes clear.
