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™️

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.

Aquasoul™ Pro 4.1

Upgrade your spa experience with the advanced Wellis AquaSoul™ Pro sound system, engineered with high-performance waterproof components for seamless integration. Say goodbye to outdated wired setups—thanks to the built-in Bluetooth receiver, you can stream music wirelessly straight from your smartphone.

Choose between the powerful 4.1 configuration, featuring a 288 W subwoofer and four discreet 30 W speakers, or the more compact 2.1 system with two integrated 30 W speakers. Both options deliver clear, immersive sound, perfectly suited to any spa setting.

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.

Smartphone App Spa Control

Control your hot tub from anywhere in the world with the Spa Control app. No matter where you are, you can stay connected to your relaxation by managing your spa directly from your smartphone. The app features an easy-to-use interface that lets you adjust temperature, manage water care, and control spa functions through a wireless or mobile internet connection. With just a few taps, you can select modes such as Beginner, Away from Home, Energy Saving, Super Energy Saving, or Weekender, and the system will handle the rest.

Hydrotherapy Jets

Wellis Spas are equipped with advanced hydrotherapy jets designed to deliver a powerful and relaxing massage experience. These jets combine strong water pressure with precise positioning to target different parts of the body, helping to relieve muscle tension, improve circulation, and promote overall relaxation. Many Wellis spas include a mix of rotating and fixed jets, allowing users to enjoy both gentle, wide-area massage and deeper, focused pressure on specific muscles. The jets can also be individually adjusted or turned on and off, giving you full control over the intensity and direction of the massage for a truly personalized spa experience.

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.
