Steam shower: Experiences, DIY

Hi, so far I have only read as an unregistered user, now I have questions about steam showers.

House construction start possibly in a few months with precast concrete.

My wife and I are enthusiastic sauna/steam bath visitors (Therme Erding) and now we also want to have such a thing in the house, but combined with a shower, so an actual wet room. The prefabricated cabins were not convincing and that’s why it will be built ourselves.
Planned was:

[*
4 people seated or 2 people lying down
[*]There should also be enough space at the shower so that two people can fit there as well.
[*]Space for the steam shower area: 2.8m x 1.6m (without seat/lying bench, shower, insulation, tiles) could still be enlarged
[LIST]
[*]I estimate about 6-8 m³, with bench and suspended ceiling

I have already read some tips:

[*]Leave 3cm open below the glass door for fresh air and circulation
[*]Make the door low so that the steam can accumulate above the door and does not escape at the first opening.

The questions would be:

[*]Has anyone had experience with a steam shower in a private home in general


[*]e.g. seating surfaces flat or body-shaped seated/lying
[*]I have read and already tried that after a steam bath session one can "neutralize" the steam with cold water (mist or atomizer), does anyone use something like that.


[*]After a few hours of searching on the web I came across a device called TOLO Ultimate Plus 12.0 kW, 12 kW so that I reach my desired temperature faster. Has anyone already gathered experience with it?

Thanks in advance for the upcoming contributions.

I just came across your topic. How far along are you? I also have a project running right now. Can you already share your experiences with me? I’m also interested in how you did your ceiling? Liquid sealing and then tiles laid?

We are not any further, we were recently at the notary, the LRA has been surveying the plots and we did not know if it concerned our plot as well and it has now dragged on.

Due to various prices, we switched to bricks and my wife wants a bathtub, so the steam shower will be smaller - 2 seats. The volume will therefore be smaller and can rely on a smaller steam unit.

Overall, the building application has not even been submitted yet and is therefore still in the planning phase.

I will design the ceiling slanted and lower, not vaulted.

I will definitely waterproof the entire shower and possibly also half a meter around it. I have not researched whether tiles can be applied directly on it either, maybe I will do it completely with microcement (keyword: seamless). You just have to make sure that it is suitable for steam baths.

How far along are you? Which generator are you taking?

Half a year has passed since then, is there anyone who has implemented something like this?

We have now reached the point where our financing is approved, the steam shower is being prepared so that the generator only needs to be installed, currently savings are necessary.
