Hi, we are having a large kitchen and utility room re tiled and I want white flat metro tiles with pale grey grout. Just after opinions on which size to go for. I want a traditional look (old house, wood effect worktops, painted units) and I'm thinking the bigger times look more "modern" somehow...the smaller ones in the pic are more of a "standard" size, 100mm x 200 mm I think and the others are 300mm long. Thoughts please?
