shawnm.....
Congrats on your new
Master Spa!
I recommend this.
Shawn you're spending thousands of dollars on a nice new spa.
It's like an investment....don't "scrimp" on the foundation.
That would be like buying a nice new home and then telling
the builder.....can ya cut any corners on the foundation?
Get a small concrete pad poured.....it'll cost about $500-$700
which is not very much compared to your new hot tub.
Best of luck and enjoyment in your new tub.
