Wet room drywall and regular drywall different thicknesses?!

[Roland112]

I will be installing moisture-resistant drywall in the shower area and regular drywall in the rest of the bathroom. The thing is, when I browse around, I see that the moisture-resistant drywall is 12.5mm thick, while the regular wall drywall is 13mm. What's the idea behind this? I need the drywall to be the same thickness. Can't find anything on byggmax.se

If nothing has changed since I last used plasterboard, "all" boards are 12.5 mm. The fact that they write 13 mm is probably just a rounding to confuse consumers.

If there is a difference of 0.5mm in the thickness of the plasterboard, it certainly doesn't matter. You likely have a greater margin of error on the studs the boards will be attached to. I've also read that plasterboards are often 12-12.5mm thick due to manufacturing, but not all sellers provide this information.

0.5mm? Do you think you can see the difference there?

 

[verktygsgurun]

Isn't a plasterboard actually 12.7mm? That is, half an inch.
That's what they were originally, and then it's just been that they write 13mm to avoid confusion?

 

[Roland112]

so you should choose 12.5mm for wet room plasterboard and 13mm for the plasterboard?

 

[Nils82]

Yep!

 

[Roland112]

It's damn strange to choose to call the same thickness two different measurements.... not misleading at all...

What are the alternatives if you want a drywall that is "dead" but better for attaching things, except for wet room drywall?

 

[fremax]

No alternative, minerit is hardly better. You use plywood behind it, or like me (foolishly stingy) OSB, but with cc450 and reinforcement where you're going to hang things.

Kind regards, fremax

No alternative, minerit is hardly better. You use plywood behind it, or like me (cheap fool), OSB, but then with cc450 and reinforcement where you are going to hang things.

Hi, as I don't want the wall to extend more than it does today (small bathroom) and since I want to use the existing pipes that stick out into the shower today, the guy at bkr.se said that you can set studs with 30cc and then only regular plasterboard is needed. Otherwise, I would have to reroute the water pipes to the shower in the wall =/

 

[Allmänobildad]

You can have studs with 30cc and single plasterboard as long as you add nogging at all fixings.

Yes, just hope the old pipes are sufficient through the new wall now that they're applying adhesive and tiles instead of a vinyl floor?!
