i think this is fairly newe to the industry, i have not seen in person only on the net...The only thing is the steps that are usually used with the tub are designed to go with the height of the spa on the ground , with it being raised you may have to do something diiferetn for steps... I still like the idea of the spa on the ground,, with it raised the other thing is the junk that will end up under neath to clean out....
