I regret not getting clearer pictures to zoom in and see the words on the instruments but I felt the need to be discreet as I was just walking by, these ocean-front home garages are rarely/NEVER left open unattended. What is this mystery chamber?
One more different angle picture in the comments, you can see the seating bench in the chamber.
If I was filthy rich and had the space, I’d go for it. Be interesting to see how fast my flesh wounds heal, throw my wife in there when she has a headache.

According to this site, might not be too expensive (I was thinking 6 figures at least)
