I can't tell for sure, but are we also seeing that the drywall corners are rounded and not squared corners? We also can't tell how this looks all the way up the wall - does it go all the way to the ceiling or does it stop short of the ceiling? What is planned to go on the top of the tile in the tub surround? Is it just supposed to be the raw edge showing?

This is where the design wasn't completely thought through in the beginning. Using the natural stone makes it even more difficult to now correct. I think I would have them remove the 4x4 tumbled marble on the face of the wall and repair the wall. It is too late to use a Schluter strip to cap off the tumbled marble raw edge so that is not an option unless you have even more tile removed. You could possibly use a small pencil liner to cover the raw edge and that will put much more space between the two types of tile and make it look more like it was planned.

Ouch. That's painful to view. You should run the floor tile (a different one if possible) into the shower and then choose a smaller scaled similar tile and do everything else. Have them tile the little bit of wall between the tub and the shower (That little bit of baseboard looks silly) and just continue it around the tub. Tile the front of the tub too. Ditch the wood. Keep it simple, since you already have plenty of shapes going on.

To echo keenplanner's post and with all due respect, there are too many tile types, styles and formats in this space (I count 7) without any thought given to transitions between them or how they work together. I would fire whoever did this and see if you can file a claim for damages since the best solution would be to tear it out and start over. The detailing is completely lacking in this layout. Maybe keep the floor tile, but the shower and floor transition is hard to stomach as is the exposed edge of the wood access panel (where is the deck overhang?). I suggest you go with solid stone pieces (not tile) for horizontal surfaces on wing wall and tub deck (can't tell in the photo if it is).

Lastly, did you get an opportunity to review this prior to installation? We always walk the owner through the tile layout since it is very expensive to fix it once grouted in (tear it out and start over at the frame/substrate). I will almost always try to find a workable solution but this looks like several displays at a tile store tossed together. Sorry about the feedback if its sounds harsh but I could not live with this.

Best way to remedy is to take the tile off the side of the wall and do not put any back on it

Thank you everyone for the input. Here is the link to the model home so that you can have a better feel of what the master bathroom is like:

The top of the tub will be granite. However, the back wall will not have the 4x4 to the ceiling. This was not explained in the design center and neither was anything else. As much as we are spending on the house, it would have been nice if somebody could tell us this is what it would look like. The model home has upgrades galore but we thought the wall would be straight and not curved. At this point, we called the builder and have a meeting with them tomorrow. I hope that we can find a solution to this.
