Thanks, onelady! Our overall bathroom dimensions are about 15 1/2' x 10' with about 6' x 6' of open floor space. I agree with mydreamhome about laying tiles on the diagonal. With the larger tiles you'll have less grout lines so that helps visually enlarge the space also. We decided on a 1/3 offset for our shower tiles because I wanted to stagger the grout lines more and, because of the size of our tile (12 x 18), being a multiple of three, the math worked out great. I'm happy with the way our tilesetter laid it out so that it looks like one tile just continues around the corner to the next wall. This is how it looks before grout, which will blend with the tile color. I definitely struggled with the tile pattern decisions since I knew that they would really impact the way the room would look. Good luck!

If there is any still out there, I'm looking for 600+ sq ft. of either 12x12 or 18x18 Dal Tile - Mardi Gras to complete a living room area. Thanks!

Bigger's better, but there are some technical considerations as you get up to those larger sizes. The requirements for flatness and deflection of the subfloor increase as the size of the tile increases. Make sure you get a tile guy who knows what he's doing so you don't end up with a bunch of lipped and cracked tiles.

I'm in the camp that thinks larger tiles make a small room look bigger. My master bath is a longer than 8 ft. but the tiled floor area is only 5-1/2 ft wide. We used 18" square tiles on the floor and put them on the diagonal. Laying them diagonal uses a bit more tile but I think it makes the room look wider. Not the best picture but maybe it will help you visualize My daughter's bathroom floor space is only 76 x61. She used 24 x 24 tiles. I think it looks look great. For comparison, here is my narrow hall bath with 12 x 12 tiles. When I redo this bathroom I plan on using bigger tiles.
