Claim 16:
17. A fluid-containing vessel comprising:
a wall defining a fluid-containing portion;
at least one jet extending through the wall for expelling pressurized fluid into the fluid-containing portion of the vessel;
a fluid circulation system comprising: a pump and a plurality of conduits for conducting fluid between the fluid-containing portion of the vessel, the pump, and the at least one jet; and
a massage pillow configured to be positioned over at least one fluid jet, the massage pillow comprising:
a cushion comprising a front surface, a rear surface, side surfaces extending between the front surface and the rear surface, and at least one drainage opening extending through the side surfaces of the cushion for draining fluid from an interior of the cushion, wherein the rear surface comprises an annular edge defining a jet opening providing access to the interior of the cushion sized to at least partially cover the at least one jet; and
a retainer assembly comprising an opening configured to align with the at least one jet and a peripheral edge that engages the annular edge of the cushion thereby providing an annular seal between the rear surface of the cushion and the retainer assembly, wherein the retainer assembly further comprises:
at least one retainer plate connected to the cushion, which comprises the jet opening configured to align with the at least one jet and the peripheral edge engaged to the annular edge of the cushion, and
at least one snap-fit connector comprising (i) a first end comprising a bulbous portion inserted through a through-hole of the at least one retainer plate for removably securing the at least one snap-fit connector to the at least one retainer plate and (ii) a second end opposite the first end, the second end comprising a threaded portion configured to be received within a threaded grommet mounted to the wall of the vessel for mounting the at least one snap-fit connector to the wall of the vessel, and

wherein the retainer assembly is configured to be removably fixed to the wall of the vessel with the at least one jet aligned with the opening of the retainer assembly and the opening of the cushion, such that fluid expelled from the at least one jet passes into the interior of the cushion, so that the massage pillow provides at least massage and/or warmth due to the expelled fluid.
