Today you have the bidets you can install on your toilet, but traditionally they were a thing on its own, that required about as much space as a toilet and all the extra pipework associated with it.
In some European/ Mediterranean countries (I suspect France may have started the trend) this caught on well, and bidets were a must have in most houses that had toilets as part of their main architectural structure. Most people in South America had bidets this way, it's rare to see a house without at least one bidet, and this comes from the culture inherited from colonial times .
Now, things are different in othe parts of the world. England seems to traditionally have the toilet separate from the house and for some reason the bidet trend never caught on. This is in turn reflected both in USA and Australia. I don't know about bidet popularity across all of Europe, but this is definitely a cultural thing and I suspect distance and language may have kept UK without bidets until relatively recently. And as you know, old habits die hard, so... Yeah in Australia I use the shower.
That would never fly in the US. They complain about water usage so much that they regulate shower heads so that they barely drip water, and toilets so that they don't have enough water to flush solid waste. The bidet would just blow the regulators' heads with all the water usage.
can confirm. i sit on the side of the bath and wash my arse with the shower. The only house i have seen in the UK with a bidet was essentially a mansion
Look up the Tushy 3.0 bidet. Costs less than 100USD, and connects to both hot and cold taps at the sink. No electricity for a heater and you get the warm bum treatment! I got one for each bathroom
Also in the UK, the aftermarket toilet attachments are not in line with building codes because of the possibility of contamination of the water supply, so it's quite complicated if you don't have room for a separate bidet.
they make attachments you can add to your terlet for such activities, although i’m guessing the UK uses some special kind of non-standard HrH style plumping fixture to supply water (like a square pipe or something?) so maybe they don’t exist there?
