Houzz is the new way to design your home.
I like the border in this design with the pencil liners flanking the 1" x 1" tiles
Different sized stone tile. Using 12" x 24" on floors and walls, 1" x 1" on shower floors with a listelle accent on walls and shower.
Nice, clean 12" x 12" shower tile with 2" x 2" shower floor tile and a listelle for an accent in the shower
This is very similar to your layou. Not that I am crazy about the design elements, but the tile height around the tub will be similar to yours, and I like the chair rail that caps it off.
This floor is interesting. A travertine looking 12" x 12" tile with a blue 2" x 2" insert.
Here's the framed accent shower wall like what I had in the design.
Here's a framed accent wall on the left and a niche with 1" x 1" tiles.
This is a nice style idea
