Simple setup. Portable design. Flexible wellness.

The Bloom™ is the most spacious model in the 2026 Caldera Fantasy Series, offering seating for six adults and 40 hydrotherapy jets in a square, sociable layout.

Designed for easy ownership

Caldera Fantasy Series hot tubs use a rotational moulding process to create a durable, stylish unibody shell that is budget-friendly and designed for years of enjoyment.

Portable and energy efficient

Lightweight yet strong, Fantasy spas are easy to move when empty. Full-foam insulation, an internal heater and a locking thermal cover help maintain consistent warmth efficiently.

Easy water care
