We recently redid our upstairs bathroom (I was a bit perturbed because we had JUST redone the flooring in there, from tile to vinyl plank, and had a feeling she'd want to remove the vanity in the future, just not this soon). It took a few weeks DIY, roughly mid August until the Friday before Labor Day. Well, we bought two vanities off of Wayfair to replace the one upstairs and then the one downstairs.
She was tired of looking at the new vanity downstairs, so she gave the let's go sign for the downstairs bathroom, but before we started demo, she asked how long I think it'd take us (this is 9/15). Given what I knew would be busy fall, I said we should be comfortably done by Halloween. She scoffed, and said something to the likes of Well, I know you, and I'll be happy if it's done by Thanksgiving. We had to reroute the plumbing (farmed that part out), then redo the drywall around the plumbing, texture behind the vanity and mirror, redo the flooring in the bath. Plumbing, drywall, texture, and flooring was done by the end of the Kansas game (spend my timeouts laying flooring). She got pretty upset around 10/13 that the bathroom wasn't done (as we had been out of town or busy the two weekends prior). 10/18: all the final touches were completed, and the original estimate of Halloween was beat by almost 2 weeks...
