My contractor is pretty useless and can't advise me. Tile shops tell me different things. So i'm hoping you guys can help! I'm going to tile a kitchen splashback wall and also the return wall which requires going into and around a window reveal. I've ordered bevelled metro tiles that are 7mm at their thickest point. Looks like i could use 8 or 10mm size trims. Which size would be best allowing for the adhesive? And which profile: straight or round? Seems straight is most common, but wouldn't round be better with beveled edges? Also, i have read that it's best to use 1/4 and 3/4 cuts so only cut (vertical) edges go in the trim. But what do you then do when you reach an internal corner? Also, what about horizontal edges, i.e. the top row of the tiles? How would you suggest using trim there? Cut or leave bevel if possible? PS: before anyway suggests mitre cuts, contractor suggested that would require a stonemason lol, so i'm pretty sure he'd squeeze a lot more money out of me for that!
