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.
Colours and cover
Fog Stone or Natural Taupe shell with Honeycomb or Waves cabinet treatments. Locking thermal covers are available in Cocoa or Grey.
