Spa construction and installation system

Abstract

A system for easier manufacture and installation of a spa using a unitary base with molded integral electrical chaseways and with vertical support members.

1 . A foundation for spa construction comprising:
 a generally flat horizontal base with a generally vertical outside wall around the periphery of the base; the flat horizontal base configured with a bottom surface to lie upon a horizontal ground surface and provide foundation for a spa;   
     the base having a pump area adjacent a first side of the base configured for location of a pump chamber
 indentations molded into the bottom surface, the indentations forming one or more chaseways from or near the pump area to or near the one or more respective second sides of the base, the indentations dimensioned for passage of electrical conductors through the formed chaseway. 
 
   
   
       2 . A foundation as in  claim 1  wherein the chaseway has a closed end by extending to a point near one or more of the respective second sides, and the chaseway and second side are constructed such that removal of material from the base at or near this point renders the chaseway in communication with outside the wall for passage of one or more electrical conductors. 
   
   
       3 . A foundation as in  claim 1  wherein the chaseway has a closed end by extending from a point near the pump area, and the chaseway is constructed such that removal of base at or near this point renders the chaseway in communication with the pump area for passage of one or more electrical conductors. 
   
   
       4 . A foundation as in  claim 1  where the base additionally comprises at least one set of paired upwardly extending indentations near the vertical wall, the upwardly extending indentations configured to form a saddle in the base, 
     the saddle dimensioned to receive a vertical structural member for support of the vertical wall and configured to assist in registration and alignment of the vertical structural member. 
   
   
       5 . A foundation as in  claim 4  wherein at least one of the paired upwardly extending indentations is configured to extend near and along the first or second side of the base to provide a finger hold.
