Shower waterproofing with window

[craigoss_]

Hi Guys,

Any waterproofers on here able to provide some advice on meeting the regulations of waterproofing a shower area with a window 1800 sill height.

See below an image I found which would be close to our new shower area design.

Certifier will need a certificate to comply with ABCB Housing Provisions 2022 which states 1800mm high waterproofing and anything within 1500mm of the shower rose to be waterproofed. However AS3740 - 2021 states you need to waterproof up to 100mm above the shower rose, which in my case you would require floor to ceiling waterproofing and therefore making any window in the shower area not comply. My certifier was not able to tell me how to handle this situation and referred me to a water proofer to provide certification.

The shower head would be somewhere between 2000-2400 from floor. I'm a bit early in the process to get the actual waterproofer involved, but need to know the details as to what shower tapware we end up going with.

Thanks guys.

Not a waterproofer so hope there is someone with first hand experience but reading the NCC regulations (section 10.2.2 b in first link) it is only required up to 1800 above floor substrate
