If you like the second layout you would have find a coordinating mosaic to go with the rest, no cut tiles in middle of the wall.

1st one..clean look

Second one, it's more symmetrical, the first one looks like the right edge was an afterthought (lack of planning) and tiles had to be cut to fit the space.

The 1st one in the 2nd the tile lines up with nothing and is not even symetrical as it the trimmed tile are not centered on the tub either

I like the second one also. I agree with A R's comment that it looks like an afterthought. I also think the second layout visually extends the width of the shower instead of emphasizing the narrow ledge area.

I think you could also add a decorative smaller tile to either side of the small middle tile(even if you need to cut it slightly smaller). The decorative tile should not be dramatically different in color but a different shimmer value as in a glass tile vs the ceramic of the others.

Well I did say MORE symmetrical meaning not 100% but eyeballing it, it looks more planned out and even spaced than the first layout.

the first

do you need visually, height or width in your bathroom? (To fool the eye)
1st one to me makes it seem wider, 2nd makes it taller

another option is to change the stacked bond. 1/3 perhaps

The second one! I agree, the third panel in the first row looks like an afterthought. Also, if there is any repairs that need to be done, it will be easier away from the baseboards and walls. It will look cleaner overall.

regarding a layout with some offset, maybe not. is this the entire wall, or does it continue to the left?

Najeebah- this is just the back wall.
For the right and left walls, also doing the same 10x30 tile.

yes I know this is only one wall. I'm asking whether it is the entire wall or a portion of it

Yes that is the entire wall Najeebah

Center the largest tile and have two equally cut lengths at each side. No cuts in the center. Keep it symmetrical.

I don't suppose you'd have a short length of tile running down the centre of any of the other 4 walls, so option 2 would look odd and out of place. You may well have offcuts at the end of a wall, it often works out so, thus option 1 would not look odd.
Also, you can add a shelf, cabinet, etc at the right end, above the ledge, which would make the offcut less noticeable at worst and seem deliberate and planned at best.
It's a different matter if you pick a different, decorative tile for the centre, in option 2. That would also then look deliberate and planned. but I'm of the opinion that would look better off centre in any case

Thank you all f or your comments! Will do center set as Dee recommended.
