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.

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.

Installation safety — qualified electrician recommended

Although the unit ships ready to plug into a standard household socket, TwoRelax strongly recommends having a qualified electrician inspect the circuit, verify correct RCD/FI protection and earth bonding, and confirm the socket is rated for continuous spa use before first start-up. This protects you, your home, and your warranty.
