  • Oooh plumbing talk. I need to get this vanity unit out before I can replace the flooring (the usual fascination with carpeted cloakrooms...)

    I figured I need to cut through the yellow dotted lines (if there's no other way of removing that back board separately... there doesn't seem one so far) but what about the drain pipe? Do I just cut the pipe (say, in the "???" marked section) as well, to join later with some kind of joiner piece (with glue or whatever)? First time doing that, although last month I took a whole WC out in the upstairs bathroom, for the same flooring reason (it had 3 separate vinyl layers on top of each other... better in theory but was actually worse to "demo")

  • Probably solvent welded pipe, so they would have had that 32mm white waste coming up from the floor or out of the wall hidden below that shelf, then glued it in place once unit was sat down.
    Empty trap out etc before you move it.
    If your putting it back, would get a 32mm straight coupler (compression if you don't have a pot of floplast glue), then cut that waste about a third up from the bottom of the shelf. Then lift off entire unit. For putting it back, cut out however many cm of pipe is requiered by the straight coupler and then compress back together, simples*

    Those chipboard vanity units, back panel will be held by 4 screw cam locks on the back surface that you can't get to. The whole unit either sits on teh floor and screwed back to wall, or hangs off some sturdy metal plates up at the top/back.

  • Thanks, will do, been procrastinating for a few months now. The OD of that white stuff seems to measure 36mm btw. Maybe 32mm is the reference to the inner diameter, or maybe I need another size of coupler.

    (edit: yeah, plumbing forums say it's the bore size... will try with 32mm first, if not, it's 40mm + bunch of sealant everywhere)

    Yes it's screwed to the back wall.
