Hi,
I am converting a little concave area of my house into a space for the washing machine and dryer. No wash tub or sink. Subfloor is concrete with tiles on top. I will also tap into the water and power from behind the wall (left wall of pic) which is the toilet with a hand basin. I will paint the walls in a bathroom paint with mold resistance however, within the Australian standards, do I need to waterproof this area or is this enough to be considered water resistant in this scenario. Just wanting to ensure I am doing the right thing legally. Thank you in advance.
