Abstract: A set of caissons for use with wave generators for swimming pools has its vertical walls prefabricated out of stainless steel prior to installation. These vertical walls include a stainless steel end wall at each end of the caissons and a stainless steel back wall extending transverse to the back of the caissons. Partition walls extend to the floor between adjacent caissons and to the ceiling of these caissons as required by the wave generator with which they are used. Stainless steel baffle dividers can also be installed within selected caissons to inhibit the production of waves within individual caissons. Additionally, a stainless steel front wall traverses the front of the set of caissons and extends from the ceiling of the caissons to a selected distance above the floor of the caissons.
