We used the same tile in 4 x 4's on the shower floor and 12 x 18's on the walls. We decided on the larger tiles for the bench and were able to have a 24 x 24 tile cut to fit the front of the bench to avoid grout lines.

Oh nice, treasure. That looks lovely. Love your baseboard effect as well.

We have decided to use the large format white subway tile on the front of the bench, so it blends in with the walls.

Thanks.
