Portable spa

A spa, comprising:

• (a) a bath having an upstanding wall;
• and
• (b) a pump assembly removably mounted to the wall of the bath, the pump assembly comprising:
• (i) a U-shaped cover having a dry, substantially concave shell coupled to a wet, substantially concave shell, and a mounting groove formed therebetween, the groove being configured to receive the wall of the bath such that the wet shell is received within the bath, the wet shell of the cover having an inlet port and an outlet port extending therethrough;
• (ii) a pump disposed within the dry shell of the cover;
• (iii) an inlet conduit extending from the inlet port to the pump;
• and
• (iv) an outlet conduit extending from the outlet port to the pump.

A self-contained, portable, spa pump assembly configured to be removably mounted to a liquid-filled container, the spa pump assembly comprising:

• (i) a pump having an inlet end and a outlet end;
• (ii) inlet plumbing having a pump end coupled to the inlet end of the pump, an inlet end configured to be disposed within the container, and an intermediate portion coupling the pump end to the inlet end;
• (iii) outlet plumbing having a pump end coupled to the outlet end of the pump, an outlet end configured to be disposed within the container, and an intermediate portion coupling the pump end to the outlet end;
• and
• (iv) a first shell defining a cavity therein, the first shell coupled of the inlet plumbing and the outlet end of the outlet plumbing;
• and
• (v) a second shell defining a cavity therein and coupled to the first shell and configured to receive the pump end of the inlet plumbing, the pump end of the outlet plumbing, and the pump within the cavity of the second shell, wherein the first shell and the second shell selectively flex outwardly to receive a peripheral wall of the container therebetween.

A spa pump assembly for use with a spa bath having a perimeter wall, the pump assembly comprising:

• (a) a first, substantially concave shell configured to be placed within the spa bath, the first shell having an inlet port and an outlet port extending therethrough and defining a cavity therein;
• (b) means for heating liquid within the spa bath, the means for heating the liquid comprising a pump;
• (c) an inlet conduit extending from the inlet port to the pump;
• (d) an outlet conduit extending from the outlet port to the pump;
• (e) means attached to the first shell for removably securing the pump and the first shell to the wall of the spa bath such that liquid from the bath flows between the first shell and the wall into the cavity;
• and
• (f) a temperature sensor electrically coupled to the means for heating the liquid for sensing the temperature of the liquid within the spa bath, the temperature sensor located within the cavity of the first shell outside of the inlet and outlet ports and conduits to thereby directly contact the liquid within the spa bath.

A spa pump assembly configured to be selectively, removably mounted on a spa bath, the pump assembly comprising:

• (a) a pump;
• (b) an inlet conduit extending from the pump to the spa bath, an inlet end of the inlet conduit configured to be disposed within the spa bath;
• (c) an outlet conduit extending from the pump to the spa bath, an outlet end of the outlet conduit configured to be disposed within the spa bath;
• (d) means for heating liquid within the spa bath;
• (e) a temperature sensor electrically coupled to the means for heating the liquid, the temperature sensor configured to be disposed within the spa bath;
• (f) first and second shells, each shell defining a cavity and an opening, the opening of each shell configured to be placed adjacent a wall of the spa bath when the assembly is selectively, removably mounted on the spa bath, the temperature sensor being disposed within the cavity of the first shell, such that the temperature sensor is located within liquid in the bath when the pump assembly is mounted on the bath, the pump being coupled to the second shell within the cavity of the second shell, such that the pump is located outside the bath when the pump assembly is mounted on the bath;
• and
• (g) a plate having opposing ends, the first and second shells coupled to opposing ends of the plate such that the first and second shells flex outwardly, then grip the wall of the spa bath when the assembly is mounted on the spa bath.
