I’m not a plumber, but as someone who bought one of these, there are a few things you need to know that aren’t explained here, or anywhere. 1. Although Roger fits this frame on what looks like standard wall studs (63mm x 38mm, or 2 1/2” x 1 1/2”) , it has a total depth of approx 95mm. This is measuring from the front face of the plywood to the back of the nuts on the angled blue plates, which hold the grey trap box in place. So if like me you were hoping to place it in the 63mm deep studded wall cavity, you can’t, as it is supplied. Even on the Abacus schematics it never gives a depth measurement, just height and length of the bracketed plywood front face. So you either need to bring out your wall studs by 30mm minimum, which for me would’ve pushed the tiled/finished wall out to far over the window, or as I did, remove the blue angled brackets, reattach the pipe elbows to the same holes, and fit the trap against the the back of the plasterboard. I had to screw from the inside of the grey trap housing into a studwork frame I made, as attaching it to the back of plasterboard wasn’t something I trusted. 2. Waste connection on the grey trap is 50mm OD, with a 50mm compression to 2” adapter supplied, which is no use when trying to adapt it to 40mm solvent weld pipe (43mm OD). So I took it to my local plumbing merchant to find out how to connect. So after watching this being fitted to a floating mock up, trying to research its dimensions, purchasing it thinking it would fit, I had modify it to squeeze it in. I like Rogers videos, I just think the full dimensions need giving somewhere so that it can be accurately designed into a bathroom wall, to remove the guesswork. Hopefully this info helps anyone thinking of purchasing one.

Your the best roger 👍👍👍

Roger the outlet is a 2" external diameter pipe but the adaptors to take a 40mm pipe are not included. Where did you get them from and if not what size will fit.

Where can you buy this basin frame? can't find one anywhere.

will take u 25 years to adapt those systems , u far behind
