My neighbor was right about caulking tubs before tiling, I gotta eat crow
Old Mr. Harrison three doors down told me two years ago to always caulk the gap between the tub and the backer board before I put tile up. I laughed at him, said it was a waste of time and silicone, that the tile and grout would handle it. Well, last month I had to rip out a shower I did in my own house because water got behind the tile and rotted the green board. I was in there with a hammer and pry bar for a full Saturday, cussing myself out. He came over and handed me a tube of 100% silicone, didn't say I told you so but the look said enough. That little extra step of filling that gap first would've saved me a weekend and $200 in materials. Has anyone else had an old timer give you advice that you ignored and paid for later?
