A corner spa for two, 162 cm on each side, 575 litres and a single 16 A socket: the Aventine is the Caldera you can put almost anywhere. Fourteen jets in a lounge seat and a LumbarSsage seat.
Scroll to turn the Aventine, or drag it. Seventy-two frames from Caldera's own 360° set.
Two seats, both with massage. Pick one to see where it works.
Every aspect of the spa’s construction — insulation, heater, circulation pump and cover — works together to keep the water hot and the energy bill low.
Available in three contemporary colours with wood grain and metallic accents, so the cabinet can be matched to what is already around it.
A moulded ridge anchors and holds you in position so the jets can work on sore muscles instead of pushing you off the seat.
Seats 2, each with its own jet layout.
Across 2 different types.
