H2O have a range of swim spas that are significantly less expensive than many rivals. 
One disadvantage of the range is that they use swim jets rather than the more powerful propeller based water current generators. 

They can still be a great place for relaxing and having fun but might not suit someone looking for the best swim experience.

H20 swim spas use acrylic shells and a steel frame.

The South Beach

This is a basic swim spa at a price of well below $20,000 . It has no molded seats, instead there are four seating ledges. Water currents are supplied by nine big hole swim spa jets with 5 Water Pumps- 3 x 3 HP, 2 x 1HP.

Revolution Swim Spa

The Revolution is a good sized swim spa with generous- and separate- swimming and relaxing areas. Separate heaters for these two areas will save you money and give you the chance to swim at a good workout temperature then slip into the hot tub for a relaxing soak and hydro massage.  

The swim area is deeper than most and there is good sized area of flat bottom space for exercise machines if you want to use them,

Overall dimensions:

19ft 6.25in x 7ft 2.61in x 4ft 10.27in/5ft 2.2in

Duo Max
The Duo Max is the largest setup from H2O. There is room for several people to use the hot tub at any one time and there are even two molded seats with hydrojets in the swim area.
