    Default Regs for building showers

    Long time reader, first time poster...

    I'm about to build a shower base into floor joists and within a timber studded frame. To make my life easier with construction and tiling I've purchased one of those grates that go along the back of the shower.

    I have two major questions:

    1) What gradient is required for the water to flow into my grate? An answer in angle degrees or the depth at the back of a 900mm wide base would be great.
    2) What is the maximum distance for timber studs around the shower?

    If anybody can direct me to where I can find the building regulations that are quoted but not specified on any documentation would be great.

    Many thanks.

    Default Regs and falls

    In South Australia, the recommended ratio of fall in a shower area is between 1:60 and 1:80 and the
    recommended ratio of fall in other wet areas that are required to drain to a floor waste is
    between 1:80 and 1:100. I suspect these recommendations would be very similar nationally but I really do not know that for sure.



    Cheers
    Juan

    Your outcome needs to be at the end of the day will be "the water must go down the hole"
    No pooling or ponding. No matter what the regs say that is the ultimate goal.
    Find the Australian standard. Someone will have it.
    c2=a2+b2;
    When buildings made with lime are subjected to small movements thay are more likely to develop many fine cracks than the individual large cracks which occur in stiffer cement-bound buildings. Water penetration can dissolve the 'free' lime and transport it. As the water evaporates, this lime is deposited and begins to heal the cracks. This process is called autogenous healing.
