NIAGARA 7 Person Hot Tub Features


Complicated water care is a thing of the past with the FROG® system. Replace bromine cartridges monthly and minerals 4x a year to maintain sparkling clear water.

Each seat in a Caldera spa is designed with jets in specific anatomical configurations, giving each of your major muscle groups a completely satisfying massage.

Enchanted evenings are yours with the SpaGlo® multi-zone LED lighting system. Illuminate the Acquarella® waterfalls or transform the water in your Utopia Series spa to a tranquil teal or radiant red for added drama.

Utopia light zones:

  1. Underwater light, Euphoria® jet and assist bar
  2. Diverter and air valves, speakers (select models)
  3. Acquarella® waterfall(s)
  4. EcoTech@reg; cabinet sconces

Fiber Cor

All Caldera Spas feature FiberCor®, an innovation that revolutionizes spa insulation. Applied at a 2lb. density, FiberCor® is 4-times denser than regular ½ lb. urethane foam.

Shells and Cabinets

The exclusive EcoTech® cabinet, with its rich colors and embossed grain, offers the aesthetic appeal of real wood while providing the durability and easy care.

Foot Ridge

The Foot Ridge® support provides a convenient anchor point to help you remain stationary while powerful jets work their magic.

Air Jet System

The Air Jet System produces a gentle soft-tissue massage through strategically located air jets.

Ultramasseuse Lounge

The UltraMasseuse® system, an exclusive feature of the Cantabria® spa, has an impressive range of options for customizing your hot tub experience. Each of the six sequence modes are adjustable, letting you melt away tension at your own pace.

Advent Control Panel

The Advent control panel gives you command of the spa’s functions at your fingertips. An auxiliary control panel, on Utopia Series spas, lets you operate your spa’s components from a second location within the spa.


The cabinet’s natural stone-like beauty and durability comes in a popular gray/earth tone palette that blends with the outdoors. It is an ideal and affordable style complement to a growing hardscape trend.
