My mom had Crohn’s so she was on the toilet a lot, and my dad got her a toto washlet, the fanciest one possible. It uses the seat as a warm water reservoir (never a cold toilet seat), has a light, and has a heated air dryer. When I grew up and we redid a bathroom, that was my single ask…and outlet next to the toilet and that device. It’s absolutely key, we put an unpowered bidet in the other bathroom and no one will use it.
