I agree with having access,  I HATE crawling under cabinets to do plumbing.

Unfortunately Splint, that is the finished floor.  It will get cleaned and a final top coat after all construction is finished.
I don't get why people do the things they do.  Maybe it saved some money. Contractor said they like the "industrial" look.
Everything has to be scribed to the lumpy concrete floor.
