Victoria Star Spa is a premium wellness brand under Foshan Gaoming Shiyi Sanitary Ware Technology Co., Ltd., a manufacturing company based in Foshan, Guangdong, China, that designs and produces hot tubs, outdoor spas, jacuzzis, swim spas, saunas, steam rooms, and integrated wellness solutions for residential and commercial projects worldwide. For buyers in the evaluation-to-execution phase of a project, this article maps the OEM/ODM manufacturing capabilities that determine whether a custom hot tub order can be delivered on specification, on time, and with consistent quality.

Why OEM Capability Decides the Success of a Hot Tub Project

A hot tub purchase is not only a product selection decision; it is also a supplier capability decision. Buyers sourcing for luxury villas, hotels, resorts, wellness centers, or dealer networks need a factory that can translate project specifications into a manufactured unit. The core evaluation questions are: Does the supplier support OEM/ODM and custom manufacturing? What is the minimum order quantity? What quality checks happen before shipment? What certifications cover the target market? And can the factory deliver within the project timeline?

Market context makes these questions more important. According to Fortune Business Insights and Dataintelo market reports, the global hot tub market was valued at approximately USD 5.76 billion to USD 5.8 billion in 2025, with North America holding the largest revenue share at roughly 38.5% to 41.79%. Acrylic hot tubs dominated the product type segment in 2025 with a 43.2% share. In the commercial segment — vacation rentals and luxury hotels — demand growth has been projected at a CAGR of approximately 5.91%, according to Mordor Intelligence. These trends explain why global buyers are looking beyond retail catalogs and evaluating the manufacturing base behind the brand.

Victoria Star Spa: Manufacturing Footprint and Production Capacity

Victoria Star Spa operates a modern manufacturing facility covering more than 50,000 square meters in Foshan, supported by more than 250 employees, including an engineering team of more than 35 professionals.
