Metal stud walls - grounds for sinks etc


Conor

Recommended Posts

Our stud wall guy has recommend full 18mm ply on bathroom walls for hanging basins, cisterns etc. This does seem the best option, but with four bathrooms and the price of ply still through the roof and no availability of OSB... Can I use 63x43mm timber to frame within the studs? Metal studs are 70mm. We also have a couple gerberit concealed wall hung cisterns which I understand come with their own frames then bolt to the floor. Do they need any additional support?

 

Cheers.

You don’t need to fully ply 

Just put them where they are are needed 

We normally put high pieces in 

Its easy to mark a drawing up accurately 

 

just use the cheap ply £8 a sheet

So you use 12mm ply then? Do you double board the rest of the wall to bring it out to match the plyed part?

@nod how do you fit the ply? Is it within the studs?

Yeah Normally directly onto the back of the PB 

In your case you should board the inside of the bathrooms first Drive a dozen or so screws through The board to grab the ply

If you need to fix the pattres to the metal 

Point the studs in opposite directions 

So you can fix through the face of the stud intro the ply

and through the side of the stud at the other side

The cheapest 18mm ply I can get is £40 a sheet, and I'd need 30 sheets! There is no OSB anywhere!

 

Could I use 3x2s within the stud channels and then use 12.5mm OSB (have loads on site) on the face?

You need to figure out where the fixings are for accessories and put a rectangle of ply in for that item, ie towel rail, a piece bigger than the towel rail fixed to the wall.

same with the sink, WC, toilet roll holder etc

I'm more worried about the 1200mm wide wall hung vanity unit... surely it'll need something more substantial?
