Thanks.

Any Sundance dealers or owners out there?  What is on a bottom of a Sundance?

tony:
I am not a dealer, but Sundance uses a hard plastic sheet attached to the bottom, different than the Jacuzzi Premium ABS pan.

Tubber:
Sundance has a full plastic hard sheeting underneath.  With the front panels removed you can clearly see it.

"The bottom of a HotSpring spa is sealed with a layer of 60# density closed cell polyurethane foam. It is almost as hard as the shell material - but thinner. It works well - my delivery guys can't even ram the tips of the forks on my forklift through the stuff, and believe me - they try. "

This would make servicing the tub a little harder

So there is a definate plastic 'tray' under a Sundance?  

I looked inside the HS's and Sundances and was surprised to see 2x4's for support!  Wood!  How long will that last?

I am surprised!

Brewman:
Pressure treated pine will last a good long time.
So will naturally rot resistant woods like cedar and redwood.  
I really have not observed what type of plastic sheeting is underneath our Optima, or how thick it is.  But when I remove the service panel to access the drain, it seems good and dry inside.  
Unless the plumbing springs an internal leak, I'd suspect it would stay dry.
