Four series, from a two-seat plug-and-play to the eight-seat Cantabria with 74 jets. All at 230 V, all with the FreshWater care system, all on display in Nerja.
Answer what you know. We narrow the twenty-three down to the ones that fit, and you can still change your mind in the showroom.

Nothing fits every answer at once. Loosen one — usually the budget — or ask us: there is nearly always a way.
Caldera's wellness team recommends fifteen to twenty minutes, four to six days a week. Here is what that does, wherever in Spain or Europe the tub ends up.
Water at 38 °C raises circulation. Buoyancy takes most of your weight off joints and spine. The jets work the muscle groups one seat at a time. And because the body cools slowly afterwards, it gets the signal it needs for deep sleep.

Phones do not come in. Twenty minutes every night, facing each other in warm water, is the cheapest couples' therapy there is, and the only one you will actually keep up.
The tub the kids beg for at seven and the one you sink into at ten. Splashing, then floating, then talking: it is the rare thing a six-year-old and a sixteen-year-old want to do together.
Steam over the terrace on a winter night is what a hot tub is for. On the Mediterranean coast no month is too cold; inland and further north, full-foam insulation and a fitted cover hold the water at 38 °C for little more than it costs in summer.
A hot tub is furniture, not building work: no licence, no architect, no project. It needs a flat, level base, a 230 V supply and a way in. We survey first, crane it in if we have to, fill it and hand it over running.
It makes the terrace a place you go to, not through. In a holiday rental, “hot tub” is a filter guests tick before they look at the price. In your own house, it is the thing every visitor asks about first.

A Caldera holds 38 °C under its cover for pennies; reheating from cold is what costs. Set it once and forget it.

No. A hot tub is a movable piece of equipment, like a piece of furniture: no licence, no architect, no project. If it goes on a roof terrace or a communal area we help you with the neighbours' paperwork, but the tub itself needs nothing.
230 V single phase, never three-phase. The Fantasy series plugs into a normal socket. Vacanza models and the Kauai run on a dedicated 16 A line. Utopia and the larger Paradise models want a 32 A line. We tell you exactly what your model needs and can send our electrician.
It depends on the model, the temperature you keep and how often you use it. Full-foam insulation and a fitted cover are what keep the bill down: holding the water at 38 °C costs far less than reheating it from cold. Ask us for the monthly figure of the model you like, calculated for where you live.
About fifteen minutes a week: rinse the filter, dip a test strip, adjust. With the FreshWater Salt System the tub makes its own sanitiser from a cartridge you change every four months, and the water lasts up to a year. If you would rather not, we do it for you on a monthly plan.
We survey first, in person on the Costa del Sol and from photos and measurements elsewhere: a door, a side passage, a garden gate. When there is no way through, we lift it over with a crane; roof terraces and upper floors are routine. We deliver anywhere in Spain, and to Portugal, France, Germany and beyond by arrangement. Placement, filling and start-up are in the price.
A filled spa with people in it weighs two to three tonnes spread over its footprint. A ground-floor terrace or a garden slab takes that without a second thought. On a roof or an upper terrace we ask for the building's load figure, or have it checked, before you buy.
Yes, and you should. Hot tubs are filled and heated in both showrooms in Nerja. Bring a swimsuit, sit in the seats you are comparing, and stay as long as you like. It is the only way to choose between a lounger and a seat.
Up to 36 months, with a decision the same day in the showroom. We show you the monthly figure for any model on this page.
Models marked In stock are installed within 24 hours of purchase. Built-to-order models and finishes come from the factory; ask us for the current lead time, and we reserve the delivery slot the day you order.
It is the most searched-for extra on the booking platforms, and the one guests mention in reviews. We set it up for rental use: a locking cover, simple controls, and a water-care plan so it is clean for every arrival without you being there.
Caldera's ComfortGuard: ten years on the shell structure of Utopia and Paradise, five on Vacanza, plus surface, components and cabinet cover on top. Warranty work is done by our own factory-trained technicians, or by our partner crews across Spain, with parts from stock.
