I'm trying to choose a new bath and can't decide whether to go for steel or acrylic. We have a shower over the bath, so I know in theory this means we should go for steel (does it? or does any one know anything to the contrary), but wondered about ease of cleaning, weight on the floor joists, slipperiness, speed with which it's ruined - any opinons would be greatly appreciated. What do you have and why do like/dislike it?
