The city of Commerce, CA, recently completed work on a $15 million aquatorium/recreational center that promises to serve as the state-of-the-art role model for future metropolitan recreational facilities across the nation.

Whether it’s the custom-cut Rosa stone exterior that was imported from Arizona or the exposed, custom-installed ductwork that keeps the swimming space conditioned and dry, this Los Angeles suburb has cut no corners in the 56,000-sq-ft Rosewood Park Community Center’s construction. The aquatorium has a 117- by 35-ft competition pool with a moveable bulkhead, plus a 75- by 20-ft warm-up pool.
