If you want the wall and floor tiles to be the hero in your bathroom I recommend you keep the vanity very simple. The white cabinet you have will be least obtrusive with a 'white' top. I love the elegance of stone and man-made stone is generally more durable. Check out Caesarstone Organic White or Frosty Carina. Although Frosty Carina has more pattern than Organic White, it's quite discrete so shouldn't compete with pattern on the tiles. If the tiles are charcoal or a dark brown/grey then either should work. Love to see a photograph when it's finished, whatever you decide.

I would attach it to the vanity, it is awkward to try and reach behind you if you attach it to the wall or you could try a freestanding one that you could put anywhere though they might take up a bit of room when space is a bit tight

Hi Helen, if you are to compare these products, their quality (which are both very good) is much the same, they just produce some different styles / paterns/ colours and textures, that are unique to their own brand. Hope this helps, Malcolm.

The tiles will just mounted on the kicker of the vanity and then caulked at the bottom to stop water seeping under them. Shouldn’t be hard to remove. Just cut along the caulking first. They look like the match the rest of the skirting and shower. Are you retiling everything?
