Welcome to our forum.
Well, living in upstate NY we get quite a few little critters (field mice) in our cellar in the winter, trying to escape mother nature's cold. I'm sure with my nice warm hot tub they will seek refuge there as well so we wanted a spa with an ABS pan, a sealed bottom, or 90%+ sealed bottom. Had decided on Caldera and called the factory today. Tech support person says none of their spas--Caldera, Hot Springs or Hot Spot have the bottom enclosed. Just "a sheet of thin plastic stapled to the bottom frame of the tub." What a disappointment. So now we're seriously re-thinking what we want to buy. Suggestions please on 3/4 person tub with a lounger with straight back, another seat with armrests and wrist and back jets. To be used 90% of time by two people but want a variety of seats we can use. Who makes spas enclosed on the bottom??? Or have others retro-fitted their spa bottom to keep unwanted vermin out before laying it down on the deck?
To clarify, the Caldera factory tech said the Caldera Kauai (the one I'm interested in) only has a sheet of poly film "stapled to the underside." just told me none of their spas have anything more than a sheet of plastic which we all know critters can chew through easily.
