Hello looking for some advice. We bought two different size tiles which the tile place assured us that the grout lines won't be an issue but the tiler thinks it will look bad. We have a black Terrazzo feature tile for wall and tub (tub is built in) and for the rest of walls and floor we are going for a plain grey tile. Issue is that the terrazzo tiles are 1cm shorter in width and 2 cm shorter in length than the other plain tile. Is there anyone here who maybe can throw a few ideas and solutions? Returning them is not an issue and I'm going crazy! This is our first home and can't help but I feel like I was an idiot for accepting the tiles.
