Here's the tub surround and the slab on the counter.
We put a 5' tub in the bathroom. Typically for a master bathroom this size, you'd put in a larger tub. Why the small one? The client really wanted a large shower, and we ran out of inches for a larger tub.
To make sure that the tub did not feel skimpy, we did a few things:
1) We used a deep tub by Bain Ultra.
2) We built a larger box to house the tub. I had the contractors make the space for the tub wider.
3) We used granite for the top so you notice the material, not the size.
P.S. The blue tape marks are for the drilling of the faucets. The glass will sit on top of the tub surround.
