We actually did get an earlier quote which was... wait for it....$23K. So maybe the third will be lower!!!
I would get 2 more estimates and then consider the middle one. We got a quote to redo our bathroom, 2 years ago, and it was $12-$14,000, then. We chose to have them do our kitchen, instead, so I am trying to save for the bathroom, now. The longer we wait the more it will cost, but I would never pay $18 or more for a small bathroom.
