You are asking the right questions!!! 1. Full Foam(must have)- it serves three puposes. Girst it supports you plumbing not your shell, to provent leaks. Second, it also supports you plumbing in shipping! Third and most important, it holds in the heat of the water so you dont spend more money on your electrice bill. 2. ABS and fiberglass are both great support to the shell! I would pay more attition to the quality of the manf.! 3. In my opinion D1 Spas are the best out there! Will Owner

The F2, F3, F4..... means filtration cycles. For example if you want the tub to filter 2 hours during the am and 2 hours in the pm set it to F2. More filtation for more use! Your unit is probaly a 110 unit and its going to take a while to heat up, maybe 4 degress an hour.

You need to fill the 6x6s due to it will flex the tub and it could crack the tub! check out our web page

I would recomind getting a mineral system for the tub, it will cut your chemical usage in half! Frog by king tech. is what i sell!

You might want to look at the diplomate by D1!

Yes you still need a GFCI ant time you are dealing with water and electrice you need one. yes you also need rebar or wire mesh, this keeps your slab from cracking with all the weight.

I would buy the tub, most manf will still cover the parts and then you can work with there tech department.

Only suggestion is check them out with the BBB!

Never heard of it! Have you tried minerals, ozone, and clorine?

Thats a very easy choice for me D1 ChairmanII! I am a D1 dealer in dallas and my LIST price for a Chairman II is 12,950. If you have a chance to by a floor model for 9950 I would jump all over it! Good luck check out

My only segestion would be check them with BBB! Check out our web page

Most of the brands that you are looking at are good brands. I sell Dimension One Spas and are very happy with them. In my opinion there are the best manf. out there.

Rubbing alcohol!

I would look up the dealers who have good standing on the BBB.

I sell AFS units by D1. Every case that i have ran into, any manf. of spas that try to convert a spa to a swim spa, the flow of the spa does not work well.
