Any suggestions on what the best material is for putting an inset wash basin into? I am looking at an area that is probably 1.5m x 0.5m, this will have the basin inset into it. I won't be doing the work but I don't want to specify something that causes too much pain for either me or the builder doing the work. Specifically, I guess it needs to be relatively easy to cut the hole in it and it won't end up rotting and falling to bits with a bit of moisture ingress.
What are the options?
