Running 32mm waste through 3x2 studs

[keen2learn]

Hi,

my plumber has suggested running a 32mm basin waste through my 3x2 wall studs in my bathroom, I'm feeling pretty uneasy about this, due to it weakening the integrity of the studs, the wall is currently down to bare studs and will be reboarded in 12mm moisture board once the plumber has done first fix, if this is the route I go down in the hope of having zero exposed pipes or avoiding boxing in, is there a way I can reinforce the drilled studs, I have posted a similar post in the building section, so sorry for potential duplicate posts.

I can't offer any advise, but that is some beautiful woodwork.

I'm not sure if your being serious or sarcastic lol, its a 1895 victorian terrace but unsure if that wall is original, as it appears all the upstairs walls are stud with lath and plaster.

I was serious, it was clearly installed by a skilled carpenter.

Can you not add framing to one side, say 38mm to cover the waste pipe?

I'm not sure I understand what you mean, do you mean to extend the studs outwards by 38mm and run the waste through the additional timber?

yes that would be your best bet, and get some extra insulation in there as you are doing it before sheeting it, the slats that you see are the Laths for the lathing plaster

Yes, you wouldn't have enough timber left by drilling through the studs as they are

Go over it with horizontal 2x2.

Then this is what I will do, I've been sat here stressing since he suggested it, I knew in my own mind it didn't leave any meat in the timber even if it isn't a load bearing wall.

Hi ianmcd, this is an internal wall, it will have moisture board and tile, do you think it needs insulation, it is a heated room and both rooms either side are heated.

Personally I would, for all insulation costs you are as well doing the job right, not too big a deal if you dont, I would though

 

[denso13]

do you think it needs insulation

It is useful for sound reduction in bathroom/toilet walls.

It's almost a text book example of herringbone noggin work (including the 1in square rail beneath the ceiling plate which the studs are notched out to locate into - that made it easier to put up quickly) and the laths are pretty even considering that they are generally something like cleaved chestnut, not sawn. Often when we open stuff up it's a lot messier and untidier than that, so I suppose it is artistic in its' own way

OP I'd have gone with boxing in as it uses less material, but if you don't want to do that sistering the wall out with treated 2 x 2 CLS is as good a way as any to go. I'd just try to avoid drilling the old studs as far as possible because they are pretty small section to start with
