From 8:30 a.m.-7 p.m. to almost finish the tub replacement with a step-in shower. We spent 2 hours the next day cleaning up the dust from surfaces not covered by the drop cloths, which in no way reflects on the installers. We knew we would have work to do and it inspired cleaning out the medicine cabinet and washing curtains! The installers asked questions, followed our requests, and were unobtrusive as possible in completing the transformation using the materials we selected.
