Anybody know where I can get a box trim 15mm wide in chrome or aluminum? Have scoured the internet but can only find 10mm. I've tiled our hallway and then ran the tiles straight through into the study off the hall. I set the tiles out for a grout line to run down the centre of the hall but this has created a problem in the study - the tiles finish at a sliding door and at one end of the sliding door there is a full tile into the cill but at the other end there is about a 20mm gap after the last row of tiles. The problem arised I think because the hallway isn't perfectly square so although I set it off on the centre of the hall, it was gradually running out down the length of the hall. It's not really noticeable in the hall but where it meets the sliding door in the study, it's very noticeable. I could cut a 20mm slither of tile to fill the gap but I think this will look pretty bad as it will gradually run to 0mm along the length of the sliding door. So my other thought was to put a 15mm box tile trim in the gap, but I can't find any 15mm wide trims. If anyone has better ideas how to address the problem, I'd be glad to hear it. Thanks.
