when i had my bath fitted after a few months i noticed the ceiling below getting damp, i re sealed the bath surround with unibond sealer and after a few weeks the sealent has come away from the bath, a friend told me that i would have to take the bath out remove the bottom row of tiles and start again. big problem there... the bath has been set into the wall and housing has been made at the side of the bath for some pipes...help!!
