I assume the vanity is a custom design - I love it, especially the storage drawers on the right. If it's custom, what's the finish / materials for the white part of the vanity?
Is it wood/MDF with a spray lacquer? If so, did your millworker do it themselves?

Laminate on wood?

Solid surface material like Avonite (seems unlikely since I see no seems, but it's a good choice for a wet environment)?

Thanks and nice work!
