Planning a small loft bathroom with a freestanding bath which will be almost (but not quite) touching the wall. No shower attached to the bath - it is just for luxuriating in and will be used by adults rather than splashy kids. This won't be a heavily used bathroom (main bathroom with shower is downstairs) - just for guests and the odd occasion when I have time for a long soak.
So - wise minds of Mumsnet... Do I need to tile the wall behind / around the bath? Or can I get away with just using bathroom paint? Would the paint be likely to peel / stain with occasional splashing? Would I regret not having tiles?
