The shower is much too small for the tile that you chose. Compromises had to be made.

I’d be much more concerned about that puddle.

It all comes down to price...it it were perfectly centered the design would be right down the middle and twice as many tiles would have to have been cut and half of each tile probably no used...just guessing, but if the tile setter quoted plain non patterned tile and you changed to pattern that needed matching, then the tiler gave you what he quoted....only you can answer the question and only you can decide it you want it ripped out and redone exactly as you would draw it on paper....tilers tile, they do not design I done think....just my opinion.

You should not address the layout now. You should have discussed upfront. I handed my contractor a picture showing where I wanted the grout joints and what should be centered on each wall.

It’s definitely off center. These decisions must be made between the tiler and the homeowner before any tile is installed. If you just went off to work and let the tiler make the decisions, it’s your fault that it isn’t the way you envisioned it. If you told the tiler how you wanted it and your instructions were ignored, it’s the tiler’s fault.

Not a good combination with any install, perfection or not. Sorry. WAY too much "feature", not great with shower floor. Based on that alone I'd rip it.

You can’t just rip it out because it will compromise the waterproofing. Meaning you rip it out and the whole shower will need to be redone, not just the one wall. It should have been addressed either before the first tile went up or when the first couple of tiles went up. Too late now

Exactly................"rip" implies DO over.Unfortunately. Or live with it. But the dark shadow on the shower floor doesn't appear encouraging, either. Or its the camera and photo.

That dark spot is a concern I think as for feature bad choice of tile for such a small shower.
