Spa System

Abstract

A spa system includes a reservoir having a side wall and a bottom defiling a spa cavity. The side all defines an upper portion heaving an upwardly-opening cavity. The upper portion of the side wall further includes a channel from the cavity providing drainage of fluid from the cavity. A fluid circulation system includes a powered pump and a plurality conduits connected to fluid outlets/jets in the spa cavity. The side wall includes at least one upwardly-opening channel above a waterline in the spa cavity. A light is positioned in the channel to provide indirect lighting for users of the spa system. The channel has an open portion configured to drain fluid splashed into the channel back into the spa cavity.

 the inner Surface of the side wall includes a step-like portion with an upwardly facing surface that forms the channel.   
   
   
       4 . The spa system of  claim 3 , wherein:
 the channel includes a central portion and opposite end portions, wherein the central portion is higher than the opposite end portions such that water drains from the central portion to the opposite end portions.   
   
   
       5 . The spa system of  claim 4 , wherein:
 the light is positioned in the central portion of the channel.   
   
   
       6 . The spa system of  claim 1 , wherein:
 the channel includes a base surface and side surfaces having a generally U-shaped cross-sectional profile.   
   
   
       7 . The spa system of  claim 6 , wherein:
 the light is mounted to the base surface and faces upwardly.   
   
   
       8 . The spa system of  claim 1 , wherein:
 the light defines a light-transmitting outer surface;   a side wall of the channel extends upwardly adjacent the light and defines an upper edge, wherein the upper edge is above the light-transmitting outer surface of the light.   
   
   
       9 . The spa system of  claim 1 , wherein:
 the side wall has four straight portions defining a generally quadrilateral shape in plan view, and wherein:   each straight portion includes at least one upwardly-opening channel and a light positioned in each channel.   
   
   
       10 . The spa system of  claim 1 , wherein:
 the side wall defines an upwardly facing surface having at least one upwardly opening beverage-retaining cavity having a lower surface, the lower surface having an upwardly extending portion, and including:   at least one light in the cavity proximate the upwardly extending portion of the lower surface.   
   
   
       11 . The spa system of  claim 10 , wherein:
 the light defines an outer surface, and the upwardly extending portion of the lower surface is above the outer surface of the light.   
   
   
       12 . The spa system of  claim 10 , wherein:
 the beverage-retaining cavity has side walls having a generally cylindrical inner surface.   
   
   
       13 . The spa system of  claim 12 , wherein:
 the side wall includes at least one upwardly-opening channel therethrough to the spa cavity to provide drainage for the beverage-retaining channel.   
   
   
       14 . A spa system, comprising:
 a reservoir defining a generally upright side wall having inner and outer surfaces and a bottom portion closing off a bottom of the reservoir, the side wall and the bottom defining an upwardly-opening spa cavity configured to retain fluid and receive one or more users;   the side wall defines an upper portion having an upwardly-opening cavity and a channel from the cavity and providing drainage of fluid from the cavity; and   a fluid circulation system including a powered pump and a plurality of fluid outlets in the spa cavity of the reservoir, and a plurality fluid conduits fluidly connecting the powered pump to the fluid outlets;   an audio speaker positioned in the cavity.   
   
   
       15 . The spa system of  claim 14 , wherein:
 the audio speaker comprises a first audio speaker;   the side wall has a generally quadrilateral shape in plan view and includes four corners, each including an upwardly-opening cavity and a drainage channel; and including:   an audio speaker positioned in each of the upwardly-opening cavities.   
   
   
       16 . The spa system of  claim 15 , wherein:
 the upwardly-opening cavity defines a bottom surface, and the channels define lower surfaces that are below the bottom surfaces of the upwardly-opening cavities.   
   
   
       17 . The spa system of  claim 15 , wherein:
 at least one of the channels extends from the upwardly-opening cavity to the outer surface of the side wall of the reservoir to drain fluid out of the spa system.   
   
   
       18 . The spa system of  claim 15 , wherein:
 each corner includes two drainage channels extending from the upwardly-opening cavities to the outer surface of the side wall of the reservoir.   
   
   
       19 . A method of making a spa system, comprising:
 providing a plurality of spa tubs, each having a side wall with an upper edge having an upwardly-opening cavity and a drainage channel extending from the cavity, each upwardly-opening cavity having a bottom surface having an upwardly extending portion;   providing a plurality of audio speakers;   mounting audio speakers in some of the upwardly-opening cavities.
