Ocean homeowners have a unique perspective on the therapeutic and restorative power of water, with wave upon wave of skin-tingling saltwater lapping at their doorsteps. But what happens when summer turns to fall, the air and water temperatures drop and it’s too cold to splash in the sea?

Savvy coastal dwellers reach for their swim spas and hot tubs, exercising or simply relaxing year-round in a mind- and body-soothing pool of hydrotherapy.

Cutting-edge innovations are taking spas and hot tubs to a new level of style and sophistication, with four industry leaders impressing the judges of Ocean Home’s Platinum List 2015.

Located in Fort Wayne, Indiana, Master Spas has Olympic swimming legend Michael Phelps lending his name and considerable star power to its Signature Swim Spas.

For our judges, the company’s standout product line is the Twilight Series, a premium portfolio of hot tubs featuring the calming effects of hydrotherapy, mood lighting and music.

The spa’s contemporary flowing lines, hydrotherapy jets, neck and shoulder massage and underwater Orion Light System combine to deliver the perfect antidote to a stressful day. masterspas.com

Our judges also loved the eye-catching swimming pool, spa and hot tub collection of Colorado-based Diamond Spas.

Featuring durable and sanitary copper and stainless steel in place of traditional materials such as fiberglass and gunite, the firm offers an array of custom pools, swim spas and water features to complement any ocean home. diamondspas.com

Bullfrog Spas, headquartered in Salt Lake City, Utah, is another market leader, incorporating the patented JetPak Therapy System into its collection of premium spas and hot tubs.

JetPaks are modular jetted spa seats that allow users to customize, interchange and upgrade their hot tub’s jetted massages at any time, offering powerful, reliable and energy-efficient hydrotherapy in any indoor or outdoor setting. bullfrogspas.com

Our judges were also impressed by California-based Cal Spas’ holistic approach to coastal living. Its Home Resort collection of swim spas, hot tubs and other wellness and lifestyle products includes indoor and outdoor saunas, gazebos, high-end barbecue grills, outdoor fireplaces and fire pits. calspas.com
