RTB insulation

Effective insulation is extremely important for hot tubs in order to reduce running costs to a minimum.

The triple “Reflective Thermal Barrier” (RTB ) insulation of WELLIS spas utilises thermal gains from the spa’s equipment, collecting any waste heat energy and reflecting it back into the plumbing and shell, whilst keeping out the colder outer air.

Insulating Cover

We manufacture all our own covers to ensure consistent quality and the highest level of thermal insulation effectiveness. This helps to keep our customer’s energy costs to a minimum. Our covers include features like a full length hinge buffer seal, internal vapour seal, and a marine grade UV resistant outer cover. The top surface slopes like a house roof so that rain can easily run off.

PULSAR Massage System

Enhances the experience! The PULSAR Massage System lets you choose from 9 different massage programs in one of the spas seats or beds.
Simply select the program and speed and the jets will pulse on and off to send the massage up and down your body.

– FM Radio
– Waterproof controller with the spa cabinet
– Subwoofer (120W)
– 2 built-in or Pop-Up speakers (35W each)


Wellis Vario Pods

A brand new technology from Wellis that brings physical massage into your spa. Imagine the fingers of your very own massage therapist pressing on your back. Very similar to the effect from a massage chair, these pods are not water jets but moving massage pods that provide a physical shiatsu type massage to the deeper tissues of the back.

Several massage programs and intensities can be easily selected from a convenient touch panel and controlled independently from the hydro jets.


Wellis REDOX System and FREE Chlorine

There is nothing more restful than the soothing environment of a Wellis spa. Especially if it is equipped with the most sophisticated, automatic spa water sanitation device.

Wellis redox and Wellis FREE CHLORINE dosing systems offer a smart, simple and economic solution that keeps your spa water safe, crystal clear and wonderfully pleasant for a whole year between water changes. The system measures directly and controls the ph value and level of free chlorine by redox probe.

We can fit Wellis REDOX to selected Wellis models for domestic use and Wellis FREE CHLORINE for public use.

In.clear Automatic Water Treatment System

Easy to use and built to last, the in.clear in one of the most efficient water sanitation systems offered to the spa and hot tub industry today. In.clear generates and releases bromine in the spa water, rapidly destroying any microbiological contaminants such as waterborne bacteria, algae, and organic matter given off by spa bathers.

The in.clear system eliminates the need to add products to your spa on a regular basis. The in.clear system does not produce any offensive odours, it does not cause eye or skin irritation and it is easy to use, making it the best choice for hot tub sanitisation.

Spas using the in.clear system need very little maintenance, and in.clear can be easily installed on new or existing spas.


Additional Heater (3kW)

An extra heater is available for colder winter climates. This effectively doubles the heaters capacity to maintain high water bathing water temperatures in exceptionally cold environments. Please ask your dealers advice.


Scandinavian Insulation

For extreme climates we offer the option for our “Scandinavian” insulation. This has a much higher insulation rating with triple layer Polyfoam panels and additional under spa rim and floor pan insulation. Only recommended for extreme sub zero temperatures and not for more temperature climates.
1) Poliurethane spa rim insulation
2) 3.5 cm thick polyfoam insulation between spa cabinet and floor pan
3) 3.5 cm thick polyfoam spa cabinet insulation



Tyrol Thermowood Cabinet




A great fitness and rehabilitation appliance.

The Aquabike is recommended to those who seek a general fitness training, need exercises for rehibilitation, or simply enjoy cycling. Its stainless steel structure and outstandinly stable construction offer safe user-experience. It is perfectly balanced, four PVC feet are responsible for avoiding sliding on the bottom of the pool. The Aquabike is completely submerged in water, therefore the resistance of the water makes training harder, which helps faster shaping of muscles and the acceleration of heartbeat. Release the plates that can be found on the pedals to increase resistance and to make your training even more dynamic and efficient.




Training and Rowing set

The expander combined with the paddles offers the experience of real rowing. At the same time, the expander alone, fixed to the attachment on the side of the pool, can be used for a number of different fitness trainings.




An indispensable accessory to gentle training.

New opportunities in hydrotherapy. The Wellis underwater treadmill provides its users the intensity of a running training on sports grounds or on a traditional treadmill while being lenient, as moving in the water eliminates the harmful and demanding effects of running on joints. It is equally appropriate for people seeking fitness training, for rehabilitation purposes or for those who simply enjoy running. Its stainless steel structure makes is resistant to ageing and its outstandingly stable construction allows easy usage.



Aqua Training Set




The W-Power Turbine – instead of the 3 hydromassage pumps- is capable to spin 50-160 m3 water per hour. In contrast to standard swim spa pumps Rio Grande’s turbine produces by 75% less power consumption while delivering twice the amount of water. The incredible performance combined with energy efficiency.


Quality Assurance

Our quality is continuously benchmarked against the highest German production standards un the TUV Certification Protocol that we subscribe to. This ensures we constantly meet and exceed all relevant international quality standards.



CE Label

On all our products reassures our customers that the design and build meets or exceeds all relevant EU standards


Poli-Max™ shells are a technological triumph, WELLIS have developed an entirely eco-neutral Acrylic/Abs/ polymer laminate system that results in a stronger, lighter, more stable, eco friendly and ultimately bio degradable product. It even self insulates for both heat and sound, significantly lowering running costs as well as making our spas probably the quietest as well as safest for your family you can buy. Ecologically sound product, easily degradable, (unlike fibreglass it does not give off any hazardous styrol gas). Thus it is not classed as hazardous and meets all relevant EU standards.

Effective insulation is extremely important for hot tubs in order to reduce running costs to a minimum. The triple “reflective thermal barrier” insulation of Wellis Spas utilises thermal gains from the spas equipment, collecting any waste heat energy and reflecting it back into the plumbing and shell. whilst keeping out the colder outer air.

The spa heat map picture is an infrared image of a Wellis spa which shows the efficiency of the RTB system. The persons face is red, indicating a high heat loss, whilst the pastel green and blues of the WELLIS spa indicate a very low heat loss as almost all the heat is kept inside the spa and cabinet.

The Wellis Spa produced excellent results in the Heatmap test

The temperature of the water in the spa visible in the picture is 35 °C, while that of the outer covering and the thermal cover is merely 4 °C. The outdoor temperature is -5 °C.

Reinforced moulded ABS floor pan

The insulated one piece moulded floor pan forms the foundation upon which we build our spas.

The pan sides extend upwards and form a moisture and insect proof barrier to protect the spas structure from the detrimental effects of damp ground.

Our reflective barrier insulation system extends across the floor pan to prevent valuable waste heat being drawn through the base by the “cold sink effect” that is created by damp floor.



WPS (Wellis Polystyrol) cabinet frame immortality for the spa cabinet’s frame

The special polymer ensures exceptional stability and life for the Spa’s structural frame – Protecting and extending the life of your investment even further.
