kinda hijacking the op thread....
i find a used jacuzzi for free or cheap, then either remove the wall (not so good) or the roof/ceiling (much better) and install the jacuzzi after leak testing it. Then i convert the pumps to small 110 volt clear water pumps from northern tool, like this one:
I use a plate heat exchanger to heat the water utilizing engine coolant:
in one bus a small residential fuel oil boiler to heat water when parked.
if you put a cover on the jacuzzi, you can heat 400 gallons of water in under an hour of driving utilizing engine heat. In the summer you don't even need a cover.
craigslist is a good place to find used jacuzzi's. They are pretty easy to fix if they are broken...they are mostly made of standard pvc pipe, if not, you can use a "fernco" fitting
to adapt to standard pvc size. Since you are removing the pump and control board it makes it easy to find a cheap broken jacuzzi.
and you can buy a cheap temperature controller off of ebay so you can control the temp of the jacuzzi.
