Could you attach a piece of clear acrylic sheet over it?

Generally it has to be Quartz, though we do love others, as sometimes they can give the right feel for the design you want. Different metals can look amazing and Quartz can't replicate these. We are just starting a project that has mainly Quartz but one side of the island will be copper . . . Can't wait to see the finished look

Hi, do you have photos of the space? Is it a light or a dark room? I would personally choose a white or light grey quartz or something like Silestone. Maybe a marble vein in it, like Calacatta Gold. You need to get some samples to see the colours in situ. But if it is a very light filled room, you could also go for a darker granite or quartz.

I love the tiles and shower!!! I think it also depends on your budget and your style. Parker Howley have some lovely painted vanities and I think this one would look fab: https://www.parkerhowleynco.co.uk/product/vanity-unit-the-italian-2-drawer/#size-countertop-material. I also think wood could look good too and tikamoon have some nice ones: https://www.tikamoon.co.uk/cat-bathroom-washbasin-unit-329.htm
