Drywall storage room / hobby room, tips

Hello everyone,

Over the holidays, I approached the topic more intensively again and also cleared the rooms accordingly in order to be able to start the project in the new year.

I would like to realize a drywall construction and cut the laminate at that spot accordingly with a plunge saw and a multitool so that I can set the profiles there.

I have already created a small sketch and also marked the cuts with the help of a cross-line laser.

It should be a drywall construction with gypsum boards – without OSB boards or similar, as I will not be hanging heavy loads or the like on the walls. I should manage up to 20kg.

I now have the following question:

I would like to create an area for a door, but for now leave the passage open, as it is simply more practical, and the room is to be separated purely for visual reasons and to increase the usable space. The appearance at the open "door spot" would not really be disturbing.

Since I obviously will not cut the laminate at this spot, I must of course know exactly how wide the "raw dimension" between the two rails must be. I would of course like to keep all options open for the future so that a door can still be installed later.

Would it still be possible to install a door frame without actually installing the door? That shouldn't be a problem, right?

What dimension would be sensible between the two rails so that an as inexpensive as possible standard sized door can be installed? Do I still have some "play" here or does the distance have to be exact? I would be very grateful for any guidance!

Second question:

What wall thickness makes sense? Since it is a purely visual room separation for us, we were thinking of 50mm profiles (standard sizes are 50, 75, 100mm). With double-sided single-layer cladding, we end up at just over 70mm wall thickness. Does that even make sense? Would there even be a door that would fit such a narrow wall? Or should I rather go for 75mm?

I look forward to any suggestions/tips!
Thank you all!

There are also standard rough opening dimensions for standard doors:


Standard frames start at 80mm with many online suppliers – that corresponds to a wall thickness of 80-95mm. So it is better to choose a 75mm wall plus plasterboard.

Stick to the shell dimensions, and then you won’t have any problems. Basically, you have enough tolerance; you don’t have to work to the millimeter – but it should be straight.

I can’t confirm now that there wouldn’t be affordable doors + frames for smaller wall thicknesses – both 50 (50–65 mm) and 70 (70–85 mm) are standard products from some online door manufacturers (Tuerenmarkt24 for example). But if you want more choice between cheap & cheap, then you need 80+ mm.

The most common drywall panels are 12.5 mm thick, so with UW/CW50 you definitely have 75 mm wall thickness. Personally, I wouldn’t go below that for single-layer cladding, even if you don’t want to hang anything on the wall.

By the way, gypsum fiberboards and also more specialized drywall panels are available in 15 mm thickness (=80 mm wall thickness with UW/CW50 profiles), but mostly not as stock items in the nearest hardware store.

If you actually want to hang something on the wall in the basement, I recommend you reconsider using double layering with drywall or also OsB. For your area, the drywall boards don't cost a fortune now, don't take significantly longer working time, and it makes the construction easier later on.

Yes, I have already heard that from several people and I will consider it again. That way, I could also easily use 50mm profiles, as the wall should normally be wide enough for standard door dimensions due to the double cladding.

For standard doors, there are also standard raw construction dimensions:


Standard frames start at 80mm with many online providers - that means 80-95mm wall thickness. So it's better to choose a 75mm wall + cladding.

Am I correct in understanding that with a raw construction width measurement of 760mm, I can't go wrong and keep all options open for a "normally wide" door?
