Abstract: A spa pool assembly has a pool that has an enclosing wall defining an interior. The assembly further includes a jet nozzle unit removably coupled to the enclosing wall and positioned in the interior, the jet nozzle unit housing a plumbing system and at least one jet nozzle. The assembly further includes a control unit that houses a pump that is coupled to the jet nozzle unit. Alternatively, a pump unit is removably received inside a channel provided in the wall and has a jet nozzle that is directed at the interior of the pool when the pump unit is received inside the channel. The jet nozzle unit, the control unit, the pump unit and the pool are separate modular units that can be assembled together quickly and conveniently.
