Could someone tell me what the normal size for a wall tile would be and what gap has been used on my picture below? I've just had my kitchen redone including floor and wall tiles, and I was a bit suprised by the size of the grout gap on the walls which appears to be exactly the same as the floor tiles. I thought the gap would be slightly smaller on the walls? Compared to Wickes product pictures of these type of tiles (pink ones below) the gap seems quite a bit bigger to me. I am not completely happy with the appearance of the tiles but I'm not completely sure if it's just that I didn't pick the right tiles for the look I was going for, or if perhaps the grout gap is changing the overall effect. I just didn't expect the grout to be quite so visible :/ I liked way they looked when they were first fixed up on the wall but once the grout went in, not so much. Thanks!
