Progress pics....Down stairs bath and that second shower in same house as last post. Tile is almost the same tile as the first. Marazzi....Vesale "Sand"-or somethin. Hate the 12x12's. They just look so "fake". (see niche for contrast, loves me some travertine) 3rd Kerdi shower.......starting to get comfortable (kinda). I used Kerdi shims (a 3x20 strip of Band) to get the mitered outside 45 in the shower to be dead on. Is that insane? Seems it would be just as good as any seam. We framed the house and planed our studs before wallboard and CBU, but it still needed a little help. I could definitely see how this could be very helpful on jobs with less than perfect walls, or floors for that matter. Should I stop now before I break something.....or is this accepted practice? oh....and I still can't even fathom putting Kerdi on drywall.
