Fifty years of hot tubs. Nothing else.

Caldera Spas has designed and built hot tubs in California since 1976, and only hot tubs. Today it is part of Watkins Wellness, the world's largest spa manufacturer, and every Caldera we sell is made in North America and serviced by our own factory-trained team.

The story

From a two-spa order to a million spas.

Caldera never made pools, saunas or anything else. Fifty years on one product is why the seats fit, the shells last and the parts are still there when you need them.

1976
Custom Fiber Engineering, a small fibreglass shop in El Cajon, California, builds a couple of custom spas for a customer. They sell faster than anything else in the shop.
1977
David Ingram buys out his partners and launches Caldera Spas as a hot-tub company.
1999
Watkins Wellness, the Vista, California company behind Hot Spring and Endless Pools, buys Caldera. Engineering, testing and warranty move to the largest spa factory in the world.
2019
The FreshWater Salt System arrives: sanitiser generated from salt, water that lasts up to a year, on every Utopia and Paradise.
Today
Four series, twenty-three models, designed and built in California and made in North America. In Nerja since the first showroom opened, with the whole range on the floor.

What every Caldera shares

Six things you get on every model, from € 3,795.

Hot Tub Circuit Therapy

Every seat massages a different muscle group. Move around the spa and the whole body gets done, from feet to neck.

Seats you stay in

Deep, cradling contours and the textured Foot Ridge keep you seated when the jets are on full.

FreshWater care

Salt-generated sanitiser (Utopia, Paradise, Vacanza) or FROG cartridges (Fantasy): fewer chemicals, softer water, less of your time.

Built to hold heat

FiberCor insulation, EnergyPro low-wattage circulation and locking covers on the acrylic series; thick rotomoulded shells on the Fantasy. All meet the California energy standard.

ComfortGuard warranty

Up to ten years on the shell structure and seven on the surface, honoured by our own technicians.

The product

What a Caldera is made of.

The three acrylic series share one construction: a cast acrylic shell bonded to a reinforced structure, FiberCor insulation blown in at 32 kg/m³, a base pan that keeps the spa off the ground, and a maintenance-free EcoTech cabinet that never needs staining. Under the water line the seats are the point: every station targets a different muscle group, from the UltraMassage lounge and the Euphoria jet to the Sole Soothers and the textured Foot Ridge that keeps you seated when the pumps are on.

Water care is where Caldera pulled ahead: the FreshWater Salt System makes its own sanitiser from a cartridge you change every four months, and on the Utopia the FreshWater IQ version tests the water for you and tells you what to do. Everything runs through the EnergyPro circulation pump on a few watts, under a 100 mm locking cover, which is why a Caldera meets the California energy standard and why the bill stays boring. The Fantasy series takes a different route to the same idea: one piece of rotomoulded polymer, a normal socket and FROG cartridges.
