Also, it may be important to consider whether the type of shower pan this entry-level- option shower floor tile will be installed on is water-in / water-out (thick-bed system with a liner and pre-slope i.e TCNA Handbook Method B-415) or if the tile will be installed on top of a sloped pan with a surface-applied membrane. If it will be installed on top of a surface-applied membrane, it is important to consider whether the draining water may be absorbed by the body of the tile as it percolates through the grout and into the bond coat and body of the tile as it makes its way to the surface- applied waterproofing layer. I do not know for certain if this will lead to an issue with bond or performance of the tile or of the system. I ran your question past a Recognized Consultant for a quick opinion. Here is the slightly paraphrased answer: “In a per- fect world, it would work, but I wouldn’t do it. Soft absorbent body, unforgiving of installation error, glazed surface. I don’t see any cost savings. Why not a cheap porcelain? Wet is one thing; soak- ing absorbent tile in soapy water is another.” – Mark Heinlein, NTCA Training Director ASK THE EXPERTS –––––––––––––––––––––––––––––––––––––––––––––––––––– CASABLANCA by VERACERAMICS.COM TileLetter | July 2019 31
