Pain? Like from them being too small or causing you to fall over or something? I’ve used them, they’re fine. IIRC quite large. I don’t remember them being amazing, so the water pressure was probably just at the ‘acceptable’ level. They have the usual drawbacks of shared showers - water and dirt creeping into the dry areas because people aren’t careful - so if I were designing a new luxury sleeping train car I’d try to get one per cabin, or maybe one per pair of cabins.
