Browse Forums Bathrooms and Laundry 1 Oct 09, 2015 3:51 am Do I want a floor waste in the separate toilet? We have a 'wet area foyer' with powder room, laundry and main bathroom off it. This area is tiled. Rest of the flooring is timber. Plumber said may not need it if powder room sink has an overflow but for us to think about it. Tiles are 300 in the powder room. Seems better to have one just in case? Re: Powder room floor waste 2Oct 09, 2015 1:21 pm I'm in NSW and I thought you had to have a floor waste in every wet area? If you are having a wall hung vanity/ sink, you could put the floor waste underneath. Not as visible then, depending on where the vanity is located. We did this in our ensuite and main bathrooms. You can't see them because the vanity is located beside the entrance to the bathroom Re: Powder room floor waste 3Oct 10, 2015 2:31 am dolphinblu I'm in NSW and I thought you had to have a floor waste in every wet area?

He seemed pretty clear on the options, maybe there's a small detail to it that means is not technically required. Our ensuite and bath have floor grates due to the long open showers and 600 tiles. I might go for one, anyway. Thanks for the tip. Re: Powder room floor waste 4Oct 10, 2015 6:32 pm From here... http://hia.com.au/hia/content/Builder/r ... rooms.aspx "Floor wastes in bathrooms - are they required? (Nat) One of the more contentious issues in relation to bathroom construction is the provision of floor wastes and when they are required. There is much anecdotal evidence out there in relation to this, but what are the facts? There are two primary documents in relation to wet areas construction: • the Building Code of Australia (BCA) 2008 and • AS 3740 – 2004 ‘Waterproofing of wet areas within residential buildings’ is the relevant Australian Standard referenced by the BCA. Both contain information on materials and methods required in relation to waterproofing bathrooms and wet areas such as WCs and laundries. The BCA has two parts: Volume 1 for Class 2 - 9 buildings and Volume 2 ‘Housing Provisions’ for Class 1 and 10 buildings. AS 3740 contains the wet area provisions relevant for Class 1 buildings (houses), residential buildings, such as apartments, and commercial buildings. The diagrams in AS 3740 indicate floor wastes for floor areas outside the shower enclosure for buildings that require this. The information in AS 3740 was subsequently transferred into BCA Volume 2 for houses unaltered and because of this it may be assumed that floor wastes are required in houses, but this is not strictly the case. Unless stipulated by State or Territory legislation or adopted as traditional practice, floor wastes are only required under BCA Volume 1 in apartment buildings, residential buildings such as boarding houses or motels and residential parts of commercial buildings, if the bathroom is located above a sole occupancy unit or public space. There is no requirement for houses. The intent of this provision is to provide protection to those other buildings and areas outside the immediate building, potentially being separation occupancies, in the event of flooding.

What do you recommend? We have one in the bathroom next door and the laundry obviously. I'm leaning towards putting it but don't really understand the benefits or disadvantages or how necessary it is. I guess if the toilet backs up.. Re: Powder room floor waste 6Oct 12, 2015 9:49 am That's exactly right. To me any wet room should have a central floor waste - laundry, bathroom, powder room etc. 99.9% of the time those rooms will be fine but in the case of a laundry where the washing machine hoses may burst or a sink in any of those other rooms overflows, then a floor waste may stop a lot of water damage to adjoining rooms or those below if it is a two storey house. I have even seen floor wastes in kitchens for the same reasons. Stewie Re: Powder room floor waste 7Oct 13, 2015 1:12 am Stewie D That's exactly right.
