Cost to redo tub surround.with backer board ceramic tile in thin set motar?
Spock (rhp): correction
correction: in humid surroundings, you have to use green board to prevent tiny water leaks from swelling the board behind the tile and ruining the work. we have no idea where you are and so don't know the cost of skilled labor. suggest you check craigslist or homeadvisor for local handymen with experience and get three quotes. btw, who is doing the removal? you or them? makes a difference to the cost, you know
Mortar is porous and there is not a product worse for wetting, especially in a shower. Adding in the cost of all the extra cleaning required to remove the mold, resetting broken mortar, etc., you should add about $10,000 for using it.
