I’ve just had tiles fitted in my first home (new build) to the kitchen floor and the connected W.C. plus I added on replacement of toilet, sink and radiator including boxing in of concealed cistern with tiling halfway up the wall in wc. I went with the 1st quote as I thought with the tiler being a semi retired one he must have done this all his life. I don’t want to moan at all as I know he had a hard time with me ordering the incorrect radiator valves and needing to get a different toilet outlet and cutting in of the vanity sink as I had a floor waste instead of a wall waste outlet. But I’m not really happy with the edges of any of floor tiling. It seems messy and he’s used a darker grout than I had asked for. So it shows up against the white tiles more. He’s also done the tiles against the kitchen unit kick boards instead of under. Some of them were not even fixed so are sitting at an angle but the tiled are right up against them. My question is - can I change the edging grout to silicone? In white. So that it’s not as noticeable? Or any other solution to make the edges look better?
