has the cabinet held up with the weight of the concrete? or is it supported seperately? Thank you!

Great job! How did you integrate the custom top with the IKEA vanity? Usually it relies on their proprietary slim drain, any other drain interferes with the top drawer.

We're happy to hear you like our work. We specified a p-trap and drain assembly that would work with a plumbing drawer and modified the drawer interior.

At last, an opaque glass enclosure! In much of France, where we often travel, the water is very, very hard, and the French cleverly handle the hard water spot problem by manufacturing the glass or synthetic doors somewhat opaque (and a bit more private) with built-in patterns like raindrops, snowflakes, flowers, etc. Kudos to this designer!
