I'm not able to install anything like this in my current home but if you live somewhere reasonably warm (so it's not super unpleasant to get a wet bum) I can hugely recommend something like this. (I want everyone to get one since I can't).

Living in Asia where the "bumgun" (bidet on a hose) is popular made me realise how barbaric toilet paper is. It's really quite disgusting and also very uncomfortable!

In India it's relatively common to see these retrofitted bidets that fit under the seat. Personally I think they're inferior to the hose but that's a personal preference, these things still work great, and they are less intrusive and probably easier to install. One of my Indian colleagues has one at his home in Europe too.
