New to Reddit. I posted a problematic job (the battle rages on), so I figured I'd post something positive. Just wrapped up this job. Had the opportunity to build the bathroom around the tile format. Everywhere possible, full tile dictates the layout. Not speaking to the aesthetic (everyone has their own taste), more to the math/layout. Layout starts at the bottom right corner of the window with full tile horizontally and vertically. That dictated everything else. Full tile borders the bench, shampoo niche, towel cubby, shower dimensions, and we built a linen tower to balance out the buildout behind the bench (there is an air handler in there, so we were married to having something behind the bench). 108 mitres, 48 floor tile, 48 ceiling tiles, 239 wall tile, 269 cuts (I think, can’t keep track). Over half of those with no coverage (aka 1mm tolerance), 28 or so holes for pots, receptacles, plumbing, mirror, vanity, etc. More man hours than I’d like to remember. We were married to the receptacle/thermostat locations, but it is what it is. We dumped some passion and brain capacity into this one. Looking forward to a night of not waking up at 3am, paranoid about missing a grout line.

Edit. A further explanation as to what I mean by ‘full tile’

We measured and checked a few options. Window was in place, and running off that worked the best we could figure (full tile at the bottom of the window left an 8" piece against the floor, and basically a full tile at the ceiling). From there, we picked the right side of the window for a grout joint, because it gave us almost equal pieces from wall to wall, and accommodated the shower size we wanted. From there, 72" is the largest single plane drain available in our area, so we went full tile on the floor (off the window wall); 6 tiles got us close to 72" (we had to get funny to make 6 tile work — 12x24 tiles are more like 11⅝" x 23¾", without grout joints). This also afforded us a large piece at the door.

From there, we framed the bench out to meet the grout joint at 6 tiles, then 2 tiles deep (big for a bench, but worked for the layout). Built out the wall behind it to hit the 2 tile deep mark. The bench width was built out to land on a full tile, and create a ~38" shower floor. The shampoo niche was framed to hit a logical tile above the bench. The towel cubby was then just put in the void, landing on full tile. Linen tower was then framed to match the depth of the shampoo niche/towel cubby, and width was made so that the reveal between the door and the tower matches the towel cubby reveal. Linen tower shelf placement alternated between full tiles. The shelf width (while not on a full tile) has equal pieces (9⁵⁄₁₆", not to say that number is burned into my brain).

Put another way... with something like 400 pieces installed, there were only 3 'L' cuts. Two above the door and 1 above the left side of the window.

Hope that makes sense. It hurt to run through that all again in my head lol.

Full tile.
