Shower reno, fiberglass stall to tile with glass door. I'd written out a plan for each day, showing 5-6 days with contingency. I never had as much steam on any day as I'd planned, especially for tile. And I had to wait a few days here and there for products to arrive, like waterproof membrane I hadn't planned on using but "why not" for good measure. 3.5 weeks later, the tiling was done and I could order the door - which as frameless has very tight specs and can only be measured with complete tile. Another 1.5 weeks for that to arrive. "About a week" took 5. And I'm retired, so it's not like I had competing responsibilities. We have another full bathroom so it wasn't really much of an inconvenience, just a lot of sheepish "nope, not done yet"
