All about waterproofing…..

Could someone out there in the blogger world help me out?

One very quick question regarding wet areas waterproofing.

I’ve been told the BCA’s 8.3.1.1 or something similar requires all wet areas to be fully waterproofed including the entire floor area especially where bathrooms (wet areas) are upstairs on timber flooring – not just the shower recessed area. What has been your experience?

This is a questions well ahead of where we are up to in our build but keen to get an idea of what is the correct process and what is the approach / experience of others.

Thanks in advance.
