Simple setup. Portable design. Flexible wellness. Refreshingly easy spa ownership.
Caldera Fantasy Series hot tubs combine an affordable rotationally moulded shell, straightforward water care and efficient insulation with the comfort and dependable performance expected from Caldera Spas.
Each Fantasy model is made using a rotational moulding process to create a durable, stylish unibody shell that is budget-friendly and designed for years of enjoyment.
Lightweight yet strong, Fantasy spas are easy to move when empty. They are ideal for patios, smaller gardens, balconies and second homes, and can move with you when your plans change.
Fantasy Series spas are ready for the FROG® sanitising system. Prefilled cartridges automatically release bromine and self-regulate according to the water’s sanitisation needs, helping keep the water soft, clean and clear with less effort.
Full-foam insulation, an internal heater and a locking thermal cover help maintain consistent warmth efficiently. Every model meets the strict portable-spa energy standards of the California Energy Commission.
