We have Pleasure-Way Plateau TS with wet bath. We do not/not sit down to shower.We have plastic curtains on velcro which covers the vanity & area wall where toilet roll is located, When in the shower we face the toilet NOT the vanity/mirror to wash and plenty of room,standing up. I am 6ft1inch 190 lbs.No problem. While I make breakfast(I cook all meals), my wife removes the plastic cover from around the vanity & side wall, quickly dries off toilet seat and puts dry mat onto shower floor. Takes a couple of minutes. There is a ceiling vent and we dont have problems with much wetness anywhere. Some Bs have sitdown showers but many Bs are like ours. We never use public facilities.The demand heater provides enough hot water for our showers and by the time the dishes are ready to wash the water is hot again.I think having the plastic curtains across & covering vanity cupboards and on the back wall keep everything dry too. That is retro-fit and not standard but easy to do.
We use our bathroom throughout the day and if it is a bit wet it's not the end of the world and certainly doesnt stay wet for long. It is a non issue for us.
Hope this info helps.
