When evaluating from a cost perspective, China is not the only option. Still, it's interesting to see that more and more international customers, especially from Europe and North America, are choosing China as their main supplier for spa components and finished products.
Why is that?
After all, the spa industry didn't start in China. Yet, from pumps and electrical controls to jet systems, covers, and lifters, many top European and American spa brands continue to rely on China as a core part of their supply chain. Some even get high-end custom products made in China.
Why is this the case? Let's explore a few factors.
Made in China: More Than Just Low Costs
Cost and technology are major factors, but China's strengths go beyond that. With modern infrastructure, efficient supply chains, and competitive labor costs, it stands out among Asian manufacturers.
What's more, Chinese factories are no longer just contract manufacturers. Many are actively involved in design and development, asking key questions about functionality, installation ease, and environmental impact.
In the spa industry, Chinese manufacturers now offer advanced equipment, standardized processes, and a clear product vision. They focus on user needs and turning complex tech into simple, effective products—making them valuable long-term partners.
However, we recommend clients carefully evaluate Chinese suppliers across five key dimensions.
Certifications
Spa components often include electrical control systems, external devices (like spa cover lifters), and plastic components. These products are subject to a wide range of regulations and market entry standards, making certifications crucial.
When it comes to certifications, here are a few things to consider when choosing a supplier:
1.Do they hold certifications like TUV or CE for electrical products?
2.Are they compliant with the EU's RoHS environmental directive?
3.Does the supplier provide their own testing reports, material data sheets, or third-party audit records?
A professional Chinese supplier won't be caught off guard by your certification requirements and will answer specific questions confidently.
Supply Capacity
While most factories can handle small sample orders, the real test comes when your orders involve hundreds or thousands of units per month. At this stage, the ability to supply consistently, stably, and with high quality becomes critical.
Here are a few points to assess supply capacity:
Does the factory have clear production capacity data? (e.g., daily output)
Do they agree to delivery deadlines and have penalties for delays?Can they provide pre-shipment videos or third-party inspection reports?
Does the supply chain have a material backup system? Are components made in-house or controllable?
Quality Control
When choosing spa accessories, quality control is crucial—it directly affects safety, performance, and compliance. Certifications are not only required for international market access but also to assess a supplier's ability to deliver. For example, accessories with electrical components often need third-party safety certifications like TÜV to be accepted in North American or European markets.
A solid quality control process includes material inspections, production monitoring, performance testing, and final compliance checks. The best suppliers also prioritize durability and efficiency testing, along with maintaining traceable technical documentation to ensure long-term stability.
When evaluating a potential supplier, be sure to understand their quality control system. Don't just rely on sample impressions or a few certifications. You should confirm:
1. Do they have a complete certification chain from third-party agencies, including reports from labs like TÜV or UL?
2. Do they have a comprehensive testing system, including durability, sealing, electrical safety, and structural stability tests?
3. Do they provide traceable quality inspection records and factory reports to ensure future quality control?
A good supplier passes the test not only in the short term but over time. When choosing, think long-term and ask the right questions.Quality isn't just about the product leaving the factory—it's about being reliable, taking responsibility, and maintaining consistency throughout the entire partnership.
Response Speed
One of the challenges of cross-border sourcing is the time difference and response speed. Many customers' main issue isn't poor quality, but rather "waiting too long"—emails go unanswered for 48 hours, sample follow-ups seem to disappear, and even at the production stage, problems keep cropping up.
Quick responses are actually a sign of respect for the partnership.
You can easily check:
Can they reply to your technical questions within 48 hours?
Do they proactively provide follow-up plans or progress updates?
Can they quickly offer changes to plans, samples, or delivery schedules to support your decision-making?
Hydrorelax Real Case
We once worked with a European client who urgently needed hot tubs for a large wellness chain, with jet assemblies that had water temperature-sensing lighting and a 60-day delivery deadline. The original supplier kept delaying the design and samples, which caused a big delay.
The client came to us, and within 3 hours of receiving the drawings, we quickly reassessed the design and used existing molds to ship the first batch of samples in just 4 days.
Their feedback: "You were the first Chinese supplier who didn't say 'It's impossible,' but said 'Let's give it a try.'
We delivered the project on time, with no issues in the first year, and the client handed us the next three batches.
