A business model for zero entry commercial hot tubs

that would be automatically cleaned after use.

My mom has a tumor in her spine that causes her great pain. One of the recommendations by her doctor would be a walk in tub for home use. She is moving out of her house to a retirement apartment before she could add one. No where in our community did the retirement apartments offer such a feature.

I was wondering if that could be a business model for a retirement community or an ancillary business set up to do it. The best option given to my mom at the first choice retirement community was the hot tub at the Y which definitely would not work (the furthest walk in the facility, screaming kids, and no zero entry but steps).

She went with the alternative - a heated pool at the number two facility that maintains a relatively high temperature (still not bath temperature level). She also still needs to contend with steps, but the walk is much shorter and she doesn't have to leave the facility.

I would add one to our house, but our shower/tubs are all on the second floor. I still might add one for my wife and myself, but it doesn't do my mom any good since she can't navigate the steps.

Any suggestions?
