an inflatable air chamber defined by the top wall, the bottom wall, the internal wall, and the external wall;
a water cavity defined by the bottom wall and the internal wall;
a jetted water pipe network that delivers jetted water to the water cavity, wherein the jetted water pipe network is substantially concealed within the inflatable air chamber;
a control system; and
a single water inlet pipe between the water cavity and the control system, wherein the water inlet pipe includes a first water passageway and a second water passageway.
12. The inflatable spa of claim 11 , wherein the control system includes a drain assembly having:
a filtered water drain passageway in fluid communication with the first water passageway of the water inlet pipe;
a jetted water drain passageway in fluid communication with the second water passageway of the water inlet pipe; and
an outlet in fluid communication with both the filtered water drain passageway and the jetted water drain passageway.
13. The inflatable spa of claim 11 , further comprising a filtering cover that covers both the first water passageway and the second water passageway of the water inlet pipe.
14. The inflatable spa of claim 11 , wherein the jetted water pipe network includes a plurality of spray nozzles, a first connecting pipe that delivers water to the plurality of spray nozzles, and a second connecting pipe that delivers air to at least one of the plurality of spray nozzles, wherein the plurality of spray nozzles, the first connecting pipe, and the second connecting pipe are substantially concealed within the inflatable air chamber.
15. The inflatable spa of claim 14 , wherein the first and second connecting pipes are flexible.
16. The inflatable spa of claim 14 , wherein the plurality of spray nozzles are spaced apart annularly about the internal wall of the spa.
17. The inflatable spa of claim 11 , wherein the air chamber is inflated to a pressure greater than about 0.8 psi.
18. The inflatable spa of claim 17 , wherein the pressure is about 1.5 psi.
19. The inflatable spa of claim 11 , wherein:
the internal wall defines a single opening for the water inlet pipe, such that both the first and second water passageways extend through the single opening in the internal wall; and
the external wall defines a single opening for the water inlet pipe, such that both the first and second water passageways extend through the single opening in the external wall.
20. The inflatable spa of claim 11 , wherein the water inlet pipe includes a separating wall between the first and second water passageways, and wherein the first and second water passageways are parallel to each other.
