tiles

[Elaine]

i want to buy white tiles to tile my window cill in the conservatory but can't find any that are 18cm deep, are all tiles standard 15/20/25/33 in size?

It is going to be nearly impossible to find tiles to fit your own specs - trimming a few centimetres off shouldn't be difficult with a tile trimmer

Have you thought of using mosaic tiles instead - they come in sheets (which I think you can cut to the size required) or individual little tiles - you could have great fun with a selection of different colours !
