We are remodeling a small bathroom, about 60 x 90 inches. We are removing the tub and replacing it with a shower, and decided on off-white tiles with some grayish veins. Tiles come in 12x24 and 24x48 inches, which size would you use? I think the larger ones will keep the veins , the design together, less broken, but I'm not sure large tiles is a good idea in a small bathroom. What do you suggest/recommend? Thank you.
