Hi everyone. I am redoing a tub/shower combo. Granite tile will be used on and above the tub, vertically transitioning to Oceanside Glass 4×8 field tiles (0.25 in thick), then transitioning to a 12-in wide border of ceramic tile mosaic (.375 in thick), and back to 4×8 glass field tiles up to the ceiling. Vertical edge will be done with the Schluter Rondec in stainless. My concerns are cracking, the thickness variation, and installation of a frameless glass shower door afterward. Cracking: I will be following Oceanside’s installation instructions, but notice that Interstyle recommends a crack suppression membrane. I will be using Schluter Kerdi membrane – will this be sufficient or do I need a separate crack suppression membrane? Is it also a good idea to put Kerdi flex between the glass zones and the granite & ceramic zones to allow for variation in expansion/contraction modulus? Is it even better to put something like Schluter Deco between the different tile materials or am I then adding just another material into the mix? Shower door: should I have the glass tile pre-drilled before installation at the glass shop so the drilling for the shower door mounts does not have to be done post installation (with possible cracking & messy replacement issues)? Thickness: Since Schluter Ditra is 1/8 in thick, AND uncouples the stresses between the substrate and tile (to some extent), can I use this in just the glass tile area and solve both the cracking and thickness issue together? Thank you in advance for any advice you can give on these subjects!_________________
