Planning to put drywall on the walls in an upcoming bathroom and then have the floor layer put up new waterproof wallpaper.

The existing studs vary from 300mm to 650mm in center-to-center measurements, all according to the previous owner's wishes and standard. :rolleyes:

I've concluded that the easiest thing is probably to screw up horizontal battens at 300mm center-to-center before putting up the drywall. However, I don't want it to add too much depth for various reasons, so I'm wondering what dimension you can safely reduce the battens to without losing too much stability? In some areas, the battens will also serve as fastening points for mounting bath mixers, towel warmers, radiators, etc.

The building standard seems to be 45x45, but I got the impression that this is mostly to accommodate insulation and electricals. In the ceiling, 28x70 works well, and in some cases, even 22x70. Can you safely go down to any of these dimensions for the battens on the walls?
 
28x70 is guaranteed to hold!

Aren't you going to have plyfa behind?

Why not incorporate a rule where it is needed instead.

Great! Just what I wanted to hear.

Plyfa instead of the slats or both slats and plyfa before the plasterboard?

Needs to be inserted in many places if so. Additionally, a lot of fiddling on two of the outer walls which partially consist of horizontal logs up to waist height where the studs have been fastened onto the logs. I end up with the same work if I have to stud vertically.
 
Having trouble finding wider gles than 28x70 for the short studs. It would have been nice with 28x140 at least for that purpose.
Is it advisable to put together two pieces of 28x70 where the mixer is to be screwed on? What happens if you accidentally place the screws right in the gap, will it hold properly or is it a risky construction?
 
28x145 is available as decking timber for 16;-/lm, it should be possible to use it here as well.

Hi, I would probably recommend using 16mm ply or my own favorite, 17mm råspont behind the drywall.

Would like to thank for all the great tips :)

My local building supply store happened to have paneling in both 28x120 and 28x145 lying around, look at that, sometimes you get lucky.
The roof is done, walls are underway.
Haven't quite decided yet what type of boards to put up. Plyfats or not. Double plasterboard or single plasterboard.
At least one wall will have to suffice with just one layer of plasterboard. Can't build too much. Just have to keep fingers crossed that no one will crash through it.

All these choices... :x

Decking wood is usually treated, right? You should never use that indoors.
 
Impregnerat should probably be avoided indoors.

What do the industry regulations say about råspont behind drywall?
