Most Common Waterproofing Mistake in Showers
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.
