Are the gray tiles on the walls opposite the tub (pictured) too much of tile? I know wainscotting/beadboard would be a wise choice but then my friends have told me it looks fine. Also - I dislike the flooring but will need to spend >$1000 to remove and replace. I've tried to wash flooring with acid but the dirt in the grout is hard to get rid off. See the pic I've posted with a close-up. I'd like some advice on 1) the existing tile color and placement 2) if I should change the tiles all over walls and around the tub (I like subway tile - simple looks) and 2) flooring options (floating resilient floors an option/concrete?) if I don't want to spend that much to get rid of it.
As an aside, this bathroom is on the main floor and is used more as a powder room. Occasional overnight guests would use it (tub) as well.
