Dear Readers, I'm renovating my bathroom: I removed the old cast-iron bathtub which was sitting directly on the wood subfloor. I=92m also removing the adjacent floor tile and its 1/4=94 plywood base, down to the subfloor as well. I plan to put down Durock and lay floor tile above that. Should I also put the Durock below the new cast-iron bathtub? Other than a minor increase in elevation of the tub, is there any reason why I shouldn=92t put Durock beneath the tub? All opinions appreicated. Thanks.
