Gypsum + OSB + Gypsum

[Appeplan]

I'm planning to start my kitchen renovation in the near future. On the current wall where I intend to hang wall cabinets above the sink, there's only a framed drywall. The room on the other side of this wall is the bathroom. I'm wondering if you see any problems with measuring out the studs on the wall, i.e., the drywall, and then adding OSB+drywall. It would then be drywall+OSB+drywall.

The reason I'm considering doing it this way is that I'm a bit worried the bathroom's surface/waterproofing might be affected if I start tearing too much in the kitchen. The bathroom has fabric with Beckers painting system + vinyl flooring.

Are there any direct drawbacks to my thinking?
How would you have done it?

No problem. However, I would have chosen a 15mm plywood board, which provides better fastening for the wall cabinets.

Thanks for the response, sounds reasonable.
Is it okay to put up plywood+gypsum regardless of the wall's cc measurement?
And is 6mm renovation gypsum on the plywood enough or should I use 12mm? I will be tiling 60cm up from the countertop, tile length about 2.3m.

Max 60/60 C/C would recommend 13 gips as it is more solid and dead than 6 mm, which can become bumpy because it is thin.

Hardly likely to become wavy with plywood behind it? You can screw the gips every 15cm if that's the case.

That's possible too, but there needs to be a bit of material for the screw head to go into. It's easy for it to go through the plaster and stop against the board behind.

Yes, of course. But if one doesn't know how to screw drywall, I don't think 13mm will help.

The thin renovation plasterboards I've encountered have a reinforcement layer and are thus harder. This means they are significantly more difficult to screw correctly for us "DIYers" and get the screws properly tightened. Since they are harder, you have to apply a bit more force so that the screw head doesn't end up above the surface, and if you apply a bit more pressure, it's easy for it to sink into the plasterboard. With 13mm, it's easier to get the screw properly tightened for the "inexperienced".

You should hit the studs fairly well.
If possible, use 12mm standard gypsum.
