I believe it is an Ikea Holvikken sink. The casework is by an awesome cabinet shop here is Seattle called Kerf. Countertop is paperstone.

Fivedot Design: did you guys design and do all of this work? I would LOVE a really similar job done in my similarly set up and what appears to be a similarly sized bathroom in our Mid-Century home. Can you share a ballpark cost for a job like this? Thank you so much.
