Invite™ – Price Upon Application

Simple setup. Portable design. Flexible wellness.

The Invite™ combines four-person seating and 25 jets with a narrower 170 cm width, making it a flexible choice where garden or patio space matters.

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

This model is ready for the FROG® sanitising system. Prefilled cartridges automatically release bromine and self-regulate according to the water’s sanitisation needs, helping keep water soft, clean and clear with less effort.
