One SwimEx pool owner in Seattle is enjoying an early summer swim thanks to their SwimEx swim spa pool! A gorgeous view and nice grill set up completes the summer package! His 600 S pool (with 2ft extension) was installed in 2005 and is still running strong! The 60-inch deep 600 S home swim spa one of the deepest and most powerful resistance pools on the market. The 600 S utilizes “side channels” as a water return system enabling a greater water depth and faster water speeds. These channels can also be used as exercise benches for a great workout before you have friends over for an all-you-can-eat BBQ!
