The tile surrounding our bathtub is very old and cracked, and I’m thinking of having it replaced with horizontal rows of wood. This would start at the top of the tub and go up to a height of 5 feet, then would continue around the rest of the room. The wood would then be painted with exterior paint. There is a shower as part of the bathtub, but it is never used. The washroom is really small, about 5 by 7, with 12 foot ceiling. The upper portion of the room is wallpapered, but I want to do something different to break up the height of the room. Can anyone think of a reason this might not work? I have seen wood applied horizontally in a washroom before, but never in the tub area. Thanks for your help.
