Spa Bottoms

[dazedandconfused]

Can anyone post a picture of the bottom of a Sundance or HS?

Unless you're living in the swamps of Louisiana, I think maybe you're worrying a bit too much here and even in wet environments like Fla and La a well designed tub shouldn’t have much of an issue. There are multiple ways used to make a spa bottom but I doubt it rarely comes into play unless someone is using untreated lumber.

i am intrigued by the spa bottoms.I do like the rewards bottom dish like thing..its a good concept.....

i also like that coleman uses steel reinforcement instead of wood,,....seems like a good gimic although wood may retain heat longer then steel.....but strength wise steel is better.......

I don't think the thermal properties of either material really matter.  And wood is not automatically inferior to steel, it all depends on the engineering.  
I'd let other criteria steer my decision.  Unless you insist on steel framing, which narrows your options considerably.

Sundance uses treated Redwood or cedar. isolated from the insulation by a liner.

Have you ever moved an old tub (ten years plus) they all have rot on the wooden structure. The bottom sits on the ground where moisture begins to eat at the wooden structure. Even redwood or pressure treated pine will eventually rot, but is sped up by leaks in the spa. I have moved hundreds of spas and when tipping them on edge a lot of them are rotted throughout. Even the pressure treated ones. The thicker the frame the longer it last's. 2x4 out lasts 2x2 and steel outlasts 2x4.
