If you're on the fence about using one due to the expense/lack of hot water option, I'd recommend trying one of the cheap ($30-50) inline cold water bidets with customizable pressure. People have a misconception that the cold water is shocking or uncomfortable, but in my experience it's actually quite soothing, and you can modify the pressure down to just a trickle to reduce that cold feeling.
I've gotten so used to it that I find myself reaching for it when I'm out in the world, even installing them in (willing) friends houses! It really does feel barbaric to use TP alone nowadays.
