underlayment for bath tubs.
Posted by manju on May 11, 19100 at 20:13:26:
I am building a custom house in austin,Texas. I have 3 bathrooms on the 2nd floor. The flooring is 3/4 inch plywood. I am afraid of water seeping from the bath tub onto the plywood with age. Do people use some sort of underlayment on which the Bathtub is mounted such as Durock or felt or both. In this case can u guys also tell me how to do it.
