Can I have the bath changed without damaging the existing tiles?

you could if you can get the bath out without disturbing the existing tilework.

There are several aspects : All depends on how strong the existing tiles are, how much time ago it was fitted , what type of a wall is behind ( is it a plasterboard or aqua panel ) and also the quality of the adhesive was used for when tiling the bathroom, some times its quite possible ,sometimes may not, a final answer could be given only if checked by professional.

Hello, generally the case is that at least the first row of tiles above the bath will have to be removed or up to the second. when the bath was originally installed the tiler would have come in after to butt the tiles straight on top of the bath and then sealed the two together with the use of silicone. Usually white tiles in a bathroom suite is easily matched up and can be purchased for a fair price as it is pretty much standard. Welwyn and Hatfield Plumbers

Ok depending on how the bath was fitted but to my knowledge most baths have a metal tap at the back wall screwed underneath tile so to remove this screw would be near impossible without popping a tile . normaly one each end fitted .if your lucky and the bath was just masticed / sealant bonded to the wall the bath legs could be lowered and standing it it would release the bath below the tile edge .would need sealant carefully cut on bath edge too ..do you have ant spare tiles if so it can be done both ways .?

Hi...sure is possible change the bath without disturbing the old tiles ....to the long wall under bath you can to use a waterproof timber for support (the old metal brackets leave under tiles)..thanks
