A carpenter would make that existing basin fit into a purpose made cabinet and then get a worktop.

Hi, I am looking for a company that sell/make bathroom vanity units with a work surface to match a marble travertine floor. The splash back will be fired earth marrakech (the background perfectly matches the existing marble floor). And the vanity unit can be left as a base as i intend to paint in farrow and ball railings. Any advice please?

I can’t see any images but it might be my internet connection as I’m in the middle of the North Sea on route to Norway. At home my vanity unit was bespoke made with a drawer pack each side and 2 full height doors under the basin in the middle. Worktop was sourced by us and then loo was purchased separately. Ask a local carpenter to do it. Easy job.

Hi, It's hard to tell without seeing photos of the tile & vanity unit colours. If you're going for a tonal bathroom look, a vanity unit in a colour close to the wall tiles will stand out the least and create a soothing look. I think you are right in thinking a dark grey unit will be too strong given the presence of anthracite on the window & towel radiator. Would you consider a wood effect vanity unit? They pair beautifully with grey and give the look warmth.
