Summary
In today's hot tub industry, manufacturers are placing greater emphasis on production efficiency and system reliability.
In today's hot tub industry, manufacturers are placing greater emphasis on production efficiency and system reliability. However, sourcing dozens of separate components such as pumps, jets, hoses, valves, and lights can be time-consuming and often leads to compatibility issues.
That's why Hydrorelax developed our Integrated Spa Accessories Kits, complete and system-tested combinations designed to save time, reduce costs, and ensure stable performance for OEM hot tub builders.
Integrated System Concept
In the past, OEM had to buy each component separately: jets, air blowers, water pumps, pipes, valves, LED lights, and control boxes. Even when every part met quality standards, small differences in size, voltage, or materials often caused installation troubles.
Hydrorelax simplifies this process by packaging common spa systems into complete kits, such as:
1.Whirlpool System Kits
2.Bubble System Kits
3.LED Lighting Kits
4.Electric Control System Kits
Each kit works perfectly on its own and can also be combined with others, giving manufacturers greater design flexibility and easy customization options.
Typical Spa Kit Examples
Spa Whirlpool System Kits
The whirlpool system is the heart of the spa experience. Hydrorelax standard kits usually include:
1.6 to 12 stainless steel or chrome jets with optional rotating, directional, or massage types
2. A matched high-performance water pump with multiple power options and US or EU plug choices
3. Suction fittings, check valves, pipe connectors, and air control valves
4. High-temperature, corrosion-resistant PVC piping
All jets and pump flows are carefully matched to ensure balanced water output and even massage pressure. This prevents any side from being too strong or too weak. All connections meet US ANSI and European EN standards, making the kits ready for markets in the US, Canada, Poland, Lithuania, and the UK.
For the North American market, we offer 60Hz motor versions, while for Europe, we provide 230V/50Hz configurations. Both are designed to ensure full electrical compatibility and compliance with local safety standards, including CE, TÜV, and RoHS certifications.
Bubble System Kits
The bubble system focuses on gentle relaxation and is often used by OEM for mid-to-high-end spas or home massage tubs. Hydrorelax bubble system kits include:
1.6 to 12 micro-air jets with optional LED versions
2.A UL-certified blower with thermal protection
3.Manifolds, PVC hoses, and clamps
4.Optional smart control module for adjustable bubble intensity
The design of the bubble system balances airflow and the number of air outlets. Hydrorelax calculates pump power (300W to 900W) and pipe flow during the design phase to ensure consistent bubble density and distribution across different tub sizes.
LED Lighting Kits
Mood lighting is an essential element of modern spa design. Our lighting kits focus not only on brightness but also on color consistency and waterproof safety.
Standard configurations include:
1.4 to 8 high-brightness waterproof LED lights (IP68 rated)
2.Controller board and remote control
3.Multi-core waterproof extension cables
4.Power adapter module
LED lighting kits support multiple colors, gradients, and synchronized modes. The light housings are sealed with corrosion-resistant resin, making them suitable for long-term use in hot and humid environments.
Hydrorelax lighting systems are also compatible with multiple brand controllers, including Balboa and Gecko platforms, allowing true plug-and-play installation.
Electric Control System
The electric control system is the core of the entire spa setup. Hydrorelax control kits include:
1.Main control box and electric heater module
2.User interface panel with push-button or touch controls
3.Temperature and water level sensors
4.Cables and safety connectors
The control system integrates seamlessly with our jets, bubble systems, and lighting kits to create a complete spa solution.
Different regions have different compliance requirements:
US and Canada: must meet UL certification with clear wiring and built-in safety redundancies
UK and EU: must meet RoHS and CE standards with cables passing moisture resistance tests
The control system also supports optional WiFi modules for remote start, stop, and temperature adjustment via an app, compatible with global power standards.
Other Systems
In addition to the four core kits, Hydrorelax offers OEM a range of auxiliary systems to create more complete and premium spa setups. These systems can be purchased separately or combined with Whirlpool, Bubble, Lighting, and Control kits to ensure design flexibility and market adaptability.
Typical systems include:
1.Circulatory System
Includes a low-noise circulation pump, filter cartridge, heater, suction, ozone generator, UV lamp and venturi to maintain clean water and balanced heat. Multiple filter areas (23–50 sq.ft) and power options are available to suit water conditions in the US, Canada, UK, and Eastern Europe.
2.Thermostatic System
Uses high-precision temperature sensors and energy-efficient heating units for accurate temperature control with automatic reheating. The system meets CE and UL safety standards and can be customized for local voltage (110V/230V) and power needs.
3.Water Feature System
It offers decorative water features like waterfall spouts, fountain jets, and lighted outlets. Paired with the main or a separate pump, they create smooth or dynamic flow effects that add both relaxation and visual appeal.
Adding these other systems allows Hydrorelax to offer a complete spa component solution. OEM manufacturers can mix and match modules according to product positioning and market demand to ensure system compatibility, stable performance, and unique market differentiation from the design stage.
The Systematic Advantages of Wholesale Kits
Every Hydrorelax spa system kit is not just a random mix of parts but a fully engineered and tested solution.
For example:
1.A standard Whirlpool System Kit with 10 jets and a 2HP pump has internal pipe lengths, elbow counts, and pump head carefully calculated to ensure even water flow under maximum load.
2.Bubble System Kits are designed so the number of air jets (usually 6 or 12) matches blower power (300W to 750W), allowing adjustable bubble density without losing airflow efficiency.
3.Lighting Kits use integrated waterproof connectors, reducing installation time by about 30 %.
4.Spa Control Kits come with pre-wired harnesses and sensors, allowing system connection by simply plugging in the modules.
This systematic wholesale approach helps OEM customers:
1.Cut their parts list (BOM) by around 40 %.
2.Save 20 to 30 % on assembly time.
3.Avoid mismatched interfaces or incompatible power from different suppliers.
4.Improve overall production consistency and simplify after-sales service.
Most importantly, Hydrorelax performs simulated assembly tests on every system before shipment to ensure coordinated flow and reliable sealing between pumps, pipes, jets, and valves.
