Most common waterproofing mistake I still see in showers It’s not the tiles. It’s not the grout. It’s what’s hidden behind them. The mistake: 👉 treating waterproofing like a “layer”, not a system. No proper corner detailing. No continuity behind benches and niches. No understanding where the water actually goes. Result: Looks perfect for 6 months. Then comes the smell, mold, and leaks. Question for you: What’s the most common waterproofing mistake you still see on jobs? Post a photo or describe it.
