Presumably that's not from the centre of the pipe? eg add 55mm?

Allow for tiles?]]> Toilet drain position in floor https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12898&Focus=215651#Comment_215651 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12898&Focus=215651#Comment_215651 Sun, 21 Dec 2014 21:10:58 +0000 djh Posted By: Chris P BaconMy advice would be to wall hang toilets and wash basins. No dirt traps around the base and much easier to mop floor.
Hmm, my wife wanted the same for the same reason. But the frames make wall-hung significantly more expensive, and in our case we can't (well, don't want to) hang from externall walls. So now we're going with back-to-the-wall pans. They're at least as smooth and less total surface area, if you add up the pan and exposed floor.

My soil pipes are very close to the wall, which is a pain. Especially if you want to add airtightness sealing. We'll have to add offsets to get them far enough away from the wall to pass through the first floor joists.]]>
