Cal Spas Freestyle F-1437

Every Cal Spas swim spa makes its current with jets on 6-brake-horsepower pumps: two "rip current" jets on the 13- and 14-foot models, plus three "power stream" jets on the 16- to 18-foot ones. Air valves and aimable nozzles change the feel, but Cal Spas publishes no speed settings, flow or current width, and variable-speed pumps are an extra-cost option. On some models a swim pump also runs seat or wall jets, and the 13-foot Family Fun is, in Cal Spas' own words, "not designed as a fitness spa".

Applies to: All nine current models; pump sharing differs by model as described.

Cal Spas' 2026 drawings label the swim area: 96 inches on the 13-foot models, 101 on the 14-foot, 138 on the 16-foot Commander, 113 on the 16-foot Depth-X and 95 on the 18-foot Olympian, whose hot tub takes the rest. That is 45 to 69 percent of the cabinet length. Water depth isn't published; the cabinets are 51 inches tall, 63 on the Depth-X.

Applies to: All nine current models.

Cal Spas builds its swim spas on a pressure-treated wood cabinet frame with galvanized steel fasteners, corner gussets and vertical bracing, under an acrylic shell it calls "Fiber Steel", a patented laminate reinforced with steel and wood. It gives the laminate as 5 layers on the swim pages and 7 on its brand page, publishes no patent number or thickness, and its warranty covers the wood frame for 2 years against 10 for the shell structure. Filled, these spas weigh about 15,000 to 26,000 pounds by Cal Spas' own figures.

Applies to: All nine current models.

Cal Spas' 2026 pre-delivery guide says all swim spas must be set by crane, which isn't part of standard delivery, on a level 4 to 6 inch slab that extends a foot past the spa, with 3 feet clear on every side. Its manual gives other slab figures, and its 150-pounds-per-square-foot rule for decks is below its own swim spas' filled weight spread over their footprint, about 153 to 190 pounds before anyone gets in. Power is one 50- or 60-amp 240-volt circuit, two circuits on the Olympian.

Applies to: All nine current models.

Standard insulation is Thermo-Shield panels in the cabinet walls plus an ABS-lined insulated floor; full foam is an upgrade. California's listings put the swim spas at 405 to 474 watts of standby, 68 to 75 percent of the limit for their size, roughly 3,550 to 4,150 kWh a year before any swimming; those tests used a 4-to-2.5-inch cover, not the 5-to-3-inch cover now standard, and the Depth-X has no listing. Cal Spas says the spas can't cool the water.

Applies to: All nine models; no California listing for the Depth-X F-1680X.

The Olympian F-1868DZ walls off a three-seat hot tub with its own control pack, pump, blower, filter and ozonator, so the swim side can sit at 80°F while the hot tub runs up to 104°F. The hot tub side runs on a separate 15-amp, 120-volt circuit, which can deliver at most 1.8 kW even though Cal Spas lists a 5.5 kW heater for it, and the swim lane shrinks to 95 inches. The other eight models are single-zone.

Applies to: Olympian F-1868DZ only; the other eight models are one body of water.

The current comes from standard 6-brake-horsepower pumps and Balboa or Gecko control packs, not a hydraulic drive, and the standard wall-panel insulation leaves the plumbing reachable. Cal Spas makes 3 feet of clearance on every side mandatory, shows where each model's pumps and control box sit, and warns that cranes, deck removal or other work to reach the equipment are billed to the owner. Its warranty allows only designated representatives and genuine Cal Spas parts.

Applies to: All nine current models.

Cal Spas' 2026 swim spa warranty reads 10 years structural, 7 surface, 5 each on equipment, plumbing and cabinet, 3 on the cover and 2 on jets, diverter valves and the wood frame, with labor included. The dealer may still charge travel and diagnostic fees, you pay freight, cranes and access, a spa that can't be repaired is replaced at 1% of current retail per month you've owned it, and coverage ends if you sell or move it.

Applies to: All nine current models.

Every model ships with a tapered 5-to-3-inch Cal Armor cover with locking tie-downs, and the Olympian gets one per zone; Cal Spas describes rigid foam and metal but not how the cover folds. No lifter is listed as standard, and Cal Spas sells manual and hydraulic-assist lifts separately without saying which fit swim spas. The cover is warranted 3 years, but after 90 days a claim pays only for a new vinyl sleeve or foam, and California's energy tests used a thinner 4-to-2.5-inch cover.

Applies to: All nine current models.

Cal Spas says its spas are made in the USA from components sourced worldwide; its only published address is a 40-acre headquarters in Pomona, California. Warranty work goes through the selling dealer or a Cal Spas-designated representative, who may charge travel and diagnostic fees, and Cal Spas publishes no dealer count or service map. Recent swim spa owners on a review site describe claims denied or stalled and parts on back order.

Applies to: All nine current models.
