It's not waterproof. Absolutely pointless putting hb in a wet area. If you want it waterproof, you'll have to tank it now. Hb is mis-sold as suitable for wet areas. What it does is allow water to pass through to the background.

I thought it was waterproof, heard a lot about it. If that is the case, then it is better just to usetanked plasterboard

Tanked plasterboard is waterproof, and if hardiebacker also needs to be tanked, what is the difference between them, apart from the price?
