Hello everyone,

The ceiling height in our basement is 204cm (80 inches). We are both 188cm (6 feet 2 inches) tall, so there isn’t much room for a dropped ceiling.
One of the rooms will have a sauna with reclining benches. Currently, the ceiling is exposed raw concrete.
The walls will be covered with drywall.

Do you have any good ideas for the ceiling? Just skim coat it? Wouldn’t that feel too cold?
Are there panels with a click system that have a low profile?

Putty it well. First the joints, then apply a full surface layer in the second pass. Sand, paint. Panels are rather unattractive.

It doesn’t feel cold – plastered and painted white, it looks like living space...

If the room height is that low, it might be a good idea to ensure that installation is possible before purchasing the sauna. Reputable manufacturers can usually make adjustments, but if it’s a kit for self-assembly, the overhead space is a critical factor. Log cabins are not suitable in this case; panel-built saunas would still be an option. Typically, ceiling panels are lifted in from above.

Plenty of indirect lighting would be beneficial to prevent the ceiling from feeling oppressive. Calm surfaces in cooler colors could help create a sense of spaciousness. In my experience, the cool tones don’t bother anyone coming out of the sauna heated.

Enjoy your build

Fill joints and holes with filler, wait overnight, then sand.
Fill again, but this time extend the filler about 40cm (16 inches) beyond each side, covering a larger area.
Wait another night, then sand again.
If you want a very smooth and even surface, you can apply filler over an even larger area and sand once more.

I wouldn’t recommend lowering the ceiling given the very limited height. For panels, you would need to lower it anyway unless you want to drill around 100 holes into the concrete. There is also ceiling fleece, which creates a smooth surface and covers the filled joints. When painting directly, the joints might show through the paint in a different shade from the rest of the ceiling (according to two painters we consulted).
