Hello all, I'm tiling my bathroom and using 360 x 240mm white tiles on the main walls, and 100 x 300 green subway (not metro) in the shower area. Can someone please tell me, what's the best way to manage the join where these two meet? Should I just butt them together with a 2mm grout joint, (the two types are the same thickness), or is there a tile trim i should use? TIA
