I like the cardboard under my knees better than a towel, it’s from the new toilet packaging. The new Buckethead shop vac from Home Depot was compact and easy to use for emptying the toilet and cleanup. Use a chisel to remove old caulking from floor, and old wax ring from flange before putting in new bolt hardware and seal. Click all parts of the new tank and bowl together, and you’re good to go. Always test flush at least three times before caulking in the base. American Standard makes the best toilets.
