I don’t know why I can’t post the drawing. I’m trying here.

if I am understanding this, you are 'Framing' the tile on the back wall?

For me, it isn't necessary to include the bullnose tiles, the 12x24 tiles can die into the corners, the glass will hide any raw edge... Unless you want a framed look?

As for the tile pattern, I might suggest, yes random out of the box, but each vein headed in the same direction, like up and to the right, for a less random or busy pattern, there are generally only about 5-7 different pieces, so watching so you don't put the same piece ndirectly next to each other helps, it will look more like a solid piece of marble, it's a personal thing.

What sizes are the bullnoses? Sometimes they do not follow the pattern direction you want. Please show what you have selected.

Lyn, the problem is that the glass for the shower does not go all the way to the ceiling and I would need a piece of schluter edge in the part not covered by the glass and I don’t lije that, that’s why I opted for the bullnose.

I can find bullnose with pattern going on the right direction

A or B is the question!

You are going to get a mess of results as your A and B are reversed in your two drawings!

Going by that last photo, A is how I have always seen it done.

Definitely A. The pattern is disrupted in B and your eye will be drawn to that instead of the tile.
