Hello,
I am planning to remodel our current laundry room in the basement of a house from 1971 into a combined bathroom/spa with a laundry area at one end. I would now like to build a new ceiling to easily and neatly run the electrical wiring and install recessed spotlights (Hide A Lite 20W, which only require about 25 mm). How should I frame for the new ceiling; can I use regular wooden studs 28x70 mm and then maybe use ventilated molding? Or should I use steel studs? Is a vapor barrier needed against the ceiling? We recently re-drained with 5 cm insulation and Platon membrane on the exterior this spring. We will also be using a humidity-controlled fan. Grateful for information on this question,

As far as I know, there are no requirements for moisture protection in ceilings?
I've even installed regular gypsum (paper) in ceilings in showers and saunas, so I think you'll be fine with wooden studs cc30 and regular gypsum in the ceiling, and you don't need to ventilate the moldings. What kind of ceiling do you have above? Joist bottom or insulation compartment or? If so, it's probably diffusion sealed there....

Ok, thanks! There is some form of concrete in the ceiling (it has been test-drilled by the previous owner to confirm there was no moisture in the ceiling). I am thinking of framing with a 28x70 mm wooden stud and attaching some form of white laminated chipboard (like from Byggmax) directly to the studs.

very old thread, so a long shot.. but I was wondering how this turned out? I am facing a similar project with the ceiling.
