I laid 1/4 hardy backer on my floor - now i have a fiberglass base ( shower ) and i need to tile the back walls of shower -- what is the best backer -- durrock or backer board Oppinions -- I do not want to ever screw with the bathroom for another 15 years -- so quality over price !
Use the durrock it is real good stuff, it hold up real well and is easy to use.
