Modular pool

Abstract

A modular swimming pool includes a precast base unit and a precast riser unit that can be assembled at an installation site to define an interior volume in which a human can swim. The precast riser unit is secured to the base unit. The upper surface of the precast base unit and at least one internal surface of the precast riser unit define the interior volume of the modular pool when the precast base unit and the precast riser unit are secured together. A modular swimming pool assembly is also provided. A method of assembling a modular swimming pool is also provided.

What is claimed is: 
     
         1 . A modular swimming pool comprising:
 a precast base unit including an uneven stepped surface having a first surface having a first height and a second surface having a second height greater than the first height, the first surface extending to a perimeter of the precast base unit;   a precast riser unit separate from the precast base unit and secured to the precast base unit, the precast riser unit including at least one internal surface, an open upper end, and a lower surface configured to engage and align with the precast base unit so the lower surface of the precast riser unit and the first surface of the precast base unit are in facing engagement at the perimeter of the precast base unit and the at least one internal surface of the precast riser unit is laterally outward of the second surface of the precast base unit when the precast riser unit is seated on the precast base unit, with the precast riser unit encircling any portion of the precast base unit that is above the first height; and   at least one precast internal structure that is separate from the precast base unit and the precast riser unit,   wherein the second surface of the precast base unit and the at least one internal surface of the precast riser unit define an interior of the pool when the precast base unit and the precast riser unit are secured together, and   wherein the at least one precast internal structure is configured to be arranged within the interior of the pool as desired by a user.   
     
     
         2 . The modular swimming pool of  claim 1 , wherein the precast riser unit includes at least one sidewall. 
     
     
         3 . The modular swimming pool of  claim 2 , further comprising at least one precast internal structure. 
     
     
         4 . The modular swimming pool of  claim 3 , wherein the at least one precast internal structure includes at least one structure selected from a bench and a step. 
     
     
         5 . The modular swimming pool of  claim 3 , consisting essentially of the precast base unit, the one precast riser unit, and the at least one precast internal structure. 
     
     
         6 . The modular swimming pool of  claim 5 , wherein the riser unit is seated on the base unit and the at least one precast internal structure is positioned on the upper surface of the base unit. 
     
     
         7 . The modular swimming pool of  claim 1 , wherein the precast riser unit includes at least one port in fluid communication with the interior of the pool. 
     
     
         8 . The modular swimming pool of  claim 7 , wherein the at least one port includes a skimmer port. 
     
     
         9 . The modular swimming pool of  claim 7 , wherein the at least one port includes a channel configured to be connected to external piping. 
     
     
         10 . The modular swimming pool of  claim 1 , wherein the precast base unit and the precast riser unit are secured together by a joining material. 
     
     
         11 . The modular swimming pool of  claim 10 , wherein the joining material is an adhesive material. 
     
     
         12 . The modular swimming pool of  claim 3 , wherein the precast base unit and the precast riser unit are secured together by a joining material, and wherein the precast base unit and the precast riser unit are secured together by the joining material. 
     
     
         13 . The modular swimming pool of  claim 12 , wherein the joining material is an adhesive material. 
     
     
         14 . A method of assembling a modular swimming pool, the modular swimming pool of  claim 1 , the method comprising:
 delivering the precast base unit and the precast riser unit to an installation site;   positioning the precast base unit at the installation site; and   securing the precast riser unit to the precast base unit so that the precast base unit and the precast riser unit define the interior of the modular swimming pool.   
     
     
         15 . The method of assembly a modular swimming pool of  claim 14 , further comprising adding a liner that extends over the upper surface of the base unit and the internal surface of the riser unit. 
     
     
         16 . The method of assembling a modular swimming pool of  claim 14 , further comprising using at least one blank to form at least one port on the riser unit in fluid communication with the interior of the pool. 
     
     
         17 . The method of assembling a modular swimming pool of  claim 16 , wherein the port is a skimmer port. 
     
     
         18 . The method of assembling a modular swimming pool of  claim 16 , wherein the port is a channel configured to be connected to external piping.
