We have had various Jacuzzis over the years.
We have settled down now to a ‘Spa-n-a-box’ It breaks down into two cardboard boxes for easy setup. It takes about thirty minutes to setup. We had it in our motorhome for a year, and now it is setup in our living room. In fact my chair as I type this is two feet from it.
I am in it twice a day. My wife once or twice. The kids too.
We had a big [8-person] Jacuzzi in our home in Washington, it was in our basement. We learned there about the H2O2 based chemicals. So we generally use them.
You can not smell it, or taste it. In fact to all human senses you would think it was faucet water just heated to bath-tub temps, but it is really spa water. Right now where it sits I filled it in March. It had been in our motorhome, but we moved into the new house in March. So that was when I filled it. I do change out the filters each week, I soak them in filter cleaning goo, and rinse them out. It takes two filters at a time, I have a total of six filters. I have had these filters since 2003. So they do last a long time.
We use the Baqua-spa chemicals, though I supplement it with cheap H2O2 from a ‘sallys supply house’, where I get it cheap.
Shop around and you can get these for right around $1,000.
