Browse Forums Renovation + Home Improvement 1 May 22, 2014 9:56 pm Hi All Since starting our reno I've been concerned about levels - excavation, footings, the backyard, step heights and now the bathroom screed. I need some help. If you're screeding a square room but the floor drain is off centre (much closer to one wall than the opposite one), how do I set the levels? I figure it's one of the below options: 1. Set the screed level around the perimeter (e.g. 35mm), set the screed around the drain lower to create fall of at least 1:100 (e.g. 25mm) and then slope to the drain - but this would see one section steeper than the other. or 2. Set the screed around the drain at 25mm, and then slope up away from the drain at 1:100, so that at the doorway the screed is 35mm, but as the drain is closer to another wall it would only be 30mm. This would mean the perimeter isn't level - does that matter? I hope the question makes sense and would really appreciate advice on what is the best method.

Most tilers will screed level all the way round the perimeter with the falls to the floor waste, that way you don't see sloping levels at the wall where it would look a bit out. Not always doable but generally the way to go. From the BCA... 2. The recommended ratio of fall within showers is between 1:60 and 1:80. 3. The recommended ratio of fall in other areas is between 1:80 and 1:100. 4. In some cases the fall in the floor finishes in the same area may vary. 5. Where falls steeper than 1:100 are not achievable, the effectiveness of the floor drainage should be confirmed to ensure that water does not remain on the finished floor in a manner that can adversely affect the health or amenity of the building occupants or deteriorate building elements. It will also be determined by how big your tiles are too. Stewie Re: Bathroom Screed/falls - help! 3May 23, 2014 7:20 am Thanks Stewie. Tiles are 300 x 300 rectified. Here is a quick layout of the floor area - my starting screed height is 37mm at the door (based on angle and floor level). Would you still use the first approach to keep the perimeter around 37/35mm, with the drain at 25mm? What you're saying about the perimeter being level makes sense, I'm just concerned that on one side the slope will be 1:100 and on the other it will be more like 1:50.

Cheers Tim Re: Bathroom Screed/falls - help! 4May 23, 2014 8:30 am That is pretty much a standard bathroom situation where the floor waste is not in the centre of the room nor is the shower waste in the centre of the shower area. Because you are only using 300 x 300mm floor tiles I'd expect you should be able to achieve those falls OK even though you may end up with some tiles cut on the diagonal in the shower to do that successfully. http://i1212.photobucket.com/albums/cc455/stewiesno1/DiagonalCutsinShower_zps3ee7fa77.jpg Another reason why floor grate channels have become popular. Stewie Levelling compound also works well for this, you can feather it and it doesn’t self level at this low thickness , you can build up in layers if need be. 2 5686 Before you rip it up, if you can in the grout lines, drill some holes and pour/inject techgrip by sika.
