The last thing i want are little angled tile pieces running along that side.
Tiling a wall that is not square.
When you get to the corners you will need to do the cutting free hand since the corner is not square any miter gage or sliding feature on the saw will not line up correctly.
With the uneven ceiling level you would normally level or laser a horizontal line that runs around the shower enclosure at the top of the tile if leaving a top border tile free see below then measure your row lines down from there to the bottom and start with any bottom trip and cuts and actually place the tile from bottom up to the top.
If you have a curved or angled wall you need to act as if the curve or angle were not there and pretend that it is a rectangle.
But obviously it s still not even close to being square.
Lippage can be eliminated on most walls by hanging new drywall or backerboard before tiling.
The general rule for laying tile is to start from the center of the area that you are going to be tiling.
However some tile layers will actually lay the top row first then work down from there to the bottom easier to get eye level rows perfectly level.
If you re tiling directly onto the wall however leveling clips and wedges will force the edges of the.
You will then want to add approximately 10 percent to that number so that you can have enough for waste.
This happens to be the side of the bathroom where a tiled shower will be and since we re using 2 x2 floor tiles i m concerned about how this is going to look with that much of a running angled gap on that side.
