Aquaterra Spas

Calavera, 21-Jet, 110v Hot Tub


Enjoy family time with the Calavera, a 110v Plug-N-Play spa with room for up to 4 adults. The unique shape and faux-wood siding makes it a perfect fit for any space. Choose one of the comfortably sculpted bucket or bench seats and let the spa’s 21 stainless steel jets lull you into relaxation.

A 1.5 HP dual-speed pump delivers soothing massages through every jet and powers a cascading, adjustable waterfall, while the 1.0 kW heater ensures your perfect temperature for every soak. Delight your friends and family with the underwater multi-color LED lighting. Control the Calavera through a stress-free, intuitive, digital control LCD panel for the ultimate hot tubbing experience.

Rest well knowing the Calavera’s included Ozone water care system provides crystal clear water with the need for fewer chemicals.

Every Aquaterra spa is designed to be extremely energy efficient with full foam insulation and included thermal locking cover with hinge seal, keeping the water hot and energy bills low. Your purchase includes a thermal locking cover and initial filter. Step not included. The Calavera is convertible to 230v (by a licensed electrician only).
