A MASSAGE TAILORED TO YOUR BODY
This model is equipped with 3 different types of hydromassage jets of varying sizes, which precisely target specific muscle groups. This ensures a comprehensive massage of the neck, shoulders, arms, back, and legs.
The jets are made of high-quality materials, which guarantees their long service life. A unique feature of JJSPA hot tubs is the ability to remove the jets. This allows you to swap jets of the same size and customize the massage to your own preferences.

Balboa - Top-tier electronics
The JJSPA Gamma 307 whirlpool bathtub is equipped with electronic components from leading manufacturer Balboa, along with a SpaNet (AUS) SV Mini 1 control unit. Optimal temperature is maintained by a 3 kW SpaNet (AUS) heater, which features two precise sensors that detect water temperature during flow. This allows for accurate readings and precise temperature regulation.
Managing the functions and status of the jacuzzi is quick and easy thanks to the SpaNet SV-MT Touch control panel, which further enhances the device's prestigious appearance. The SpaNet SV-MT Touch control panel offers optimal configuration for temperature, massage jets, filtration cycles, music, timer settings, and other bathtub functions. The panel can also be locked to prevent unauthorized access to the controls.

Energy saving with the Eco+ system
The energy efficiency of hot tubs is becoming increasingly important as consumers are becoming more aware of the importance of reducing energy consumption and protecting the environment. Energy consumption is limited by the ECO+System, which constantly maintains the water temperature. This ensures the hot tub is ready for use whenever you want it.
The tub is equipped with the ThermaCoat insulation system, in which the entire bottom surface of the shell is covered with foam of a higher density than that used in other spa products. All JJSPA brand tubs feature an ABS base, which protects the pool and its components from underneath and reduces heat loss. The thermal cover provides excellent insulation as it perfectly fits the hot tub. In this way, heat is retained, which prevents energy loss and allows you to enjoy the hot tub at any time.

JJAQUAPURE TREATMENT SYSTEM
Water purity is crucial for comfortable and safe relaxation in a hot tub. The modern JJAquaPure system has been designed to provide consistently clean and hygienic water through the use of advanced, integrated filtration and disinfection components.
One of the key elements of the system is the Ozone-Fresh ozone generator, which introduces dissolved ozone into the water to act as a natural disinfectant. Ozone effectively supports the water purification process, ensuring high disinfection efficiency while reducing the need for large amounts of chlorine or other chemical agents.
The use of an ozonator in a hot tub also allows for the elimination of unpleasant odors, keeping the water fresh, clear, and pleasant to use for a long time. The JJAquaPure system is a guarantee of hygiene, comfort, and complete relaxation in every soak.

Chromotherapy - color therapy
RGB LED lighting is more than just a visual element. Chromotherapy is an alternative method of color therapy combined with luxurious relaxation in a sauna. It helps achieve inner balance and experience positive changes in well-being.
RED: Brings warmth, energy, and stimulation. It energizes the heart and blood vessels and stimulates the senses.
YELLOW: Increases neuromuscular tension. It purifies the blood, supports digestion, and has a cleansing effect. It strongly promotes joy, brings a sense of security, and a deep sense of well-being.
BLUE: A cool, calming color. It stimulates the parasympathetic nervous system, lowers blood pressure, and calms breathing and heart rate. It helps in treating sleep disorders and headaches.
GREEN: A cool, soothing color that helps reduce swelling in joints and tissues; it calms the nervous system.
PURPLE: Promotes the proper functioning of the lymphatic system and is very helpful during menopause. It is a color that neutralizes emotional wounds and supports spiritual growth.
TURQUOISE: Increases intuition and sensitivity, and relaxes. It has a tonic effect and harmonizes the function of the lungs and the large intestine. It promotes spiritual development.

Quality is certainty
The Beta 616 model is based on a sturdy frame made of INOX pipes, which ensure high stability and durability for the entire structure. The hot tub casing is made of UV-resistant material, available in various wood-imitation finishes and colors, allowing it to perfectly match any garden or relaxation area.
Reliable operation is ensured by advanced Balboa™ electronics, combined with an efficient heating system and a modern filtration system. All these components create a cohesive system that guarantees trouble-free and long-lasting operation of the device, covered by a relevant manufacturer's warranty.
Additionally, the user has the option to choose the color of the shell, which allows for an even more luxurious and individual character of the hot tub. The shell is made of high-quality acrylic and coated with a premium layer, which ensures its high resistance to weather conditions and long-term durability even with intensive use.
FAQs
Does the number of nozzles matter?
Quantity does not always mean quality. The key is the balance between the number of jets, air flow, and the number of pumps. If these elements are not properly matched, the jets may work too weakly, resulting in an ineffective massage.
It is also worth considering which part of the body is most important to you. For example, if a back massage is not a priority, you can choose a model with jets aimed more at your legs, feet, neck, or hands.
Each seat in a hot tub has strategically placed jets, so by changing your position, you can massage different muscle groups and areas of the body, ensuring effective hydrotherapy.
How to maintain hot tub water?
When choosing a spa tub, pay attention to the filtration system. An efficient purification system not only facilitates use but also ensures hygiene and safety. You should also use water treatment products - just like in a swimming pool.
When purchasing a spa tub, you will receive a starter set of water chemicals from us.
Do I need a special installation?
Every hot tub requires access to an electrical supply, while most do not require a connection to a plumbing system. Hot tubs are typically filled using a garden hose - so the distance to a water source is a factor.
However, water drainage is important - when planning the location for your hot tub, remember that you will need to change the water from time to time. A garden hose can be attached to the drain valve to discharge the water.
You will find detailed information regarding installation requirements for each product.
How to prepare the base for a spa tub?
The base must be, above all:
- perfectly level and even
- stable and load-bearing (capable of supporting significant weight)
- resistant to moisture and weather conditions
- constructed in a way that eliminates the risk of settling
A concrete slab approximately 10-15 cm thick or paving stones will work well here. If you plan to place the hot tub on a wooden or composite deck, be sure to check the load-bearing capacity of the structure.
