Top Features

Life Scandinavian Insulation

Designed for superior heat retention and energy efficiency, the system uses tightly fitted insulation panels and built-in air chambers in the base to help maintain the water’s warmth while reducing heat escape. A reflective inner layer redirects heat produced by the massage motors back into the water, helping it warm up more quickly. Enjoy a relaxing experience with improved comfort and smart energy use.

WellisGuard™️ Eco

Delivers water that stays up to 20% fresher when the recommended chlorine levels are maintained, offering a noticeable improvement over conventional systems. The advanced design helps maintain crystal-clear water for a consistently clean and refreshing experience.

Exclusive Light Colour Therapy

The exclusive chromotherapy lighting system features a built-in underwater mood light seamlessly integrated into the spa’s side wall. Equipped with 10 to 20 LEDs, depending on the spa model, it works in sync with the main underwater chromotherapy light to create a balanced and relaxing ambiance throughout the spa.

Energy Saving W-EC pump

The water circulation pump is designed for efficient performance with very low energy consumption of just 190 W/h. Engineered for quiet operation and long-lasting reliability, it continuously maintains proper water circulation while keeping power usage minimal. Its energy-efficient design not only helps reduce operating costs but also makes it an environmentally responsible choice for maintaining clean and balanced spa water.

Smart-In Step System

The integrated step system is designed to house a 3 kW heat pump discreetly beneath the stairs. Operating efficiently in temperatures from -5°C to +40°C, it can deliver heating energy savings of up to 70–75%. The steps also feature built-in storage compartments, along with convenient options for phone charging and subtle illumination for added functionality and style.
