Hi Moz
Here's the problem. The tiles are 15mm thick - huge buggers as well I'm afraid. Here lies the problem, as the customer and female tile trim is a new concept, bath, sink, shower door, shower, taps shower tray, tiles, adhesive, grout, basin, wc and even remembered the wc seat. I thought I'd done really well but no I failed to buy the tile trim and this is where the problems began. I/we have not been able to source a trim chunky enough, so the tiles have gone on without tile trim (and the tile trim was holding up the whole bathroom job) hence my query about the aluminium strip. I have been forced to buy Porcelanosa "Perfils" for the window sills and stud wall but I need a metal strip to go along the top of the tiles as I have not tiled floor to ceiling.
