Would this truly be the suggested set up though? An inflatable pool in your dining room? I used to have hydrotherapy until I found it too difficult to actually get there. They recommended warm baths, not that I DIY one in my house!
This setup in the image looks crampy and sketchy, but in general the property owner build and maintain the pool and rent it to hydrotherapy therapists (or use it for its own such business). Normally (well, excluding cases we see in this community) one does not build one just for themselves in their livingroom or kitchen.
Imagine paying to use someone’s “hydrotherapy pool” only to turn up and see this! 😂 yeah, there’s a house near me that has a small indoor swimming pool that’s rented out for hydro. It’s really expensive though.
