As residential and commercial bath spaces continue to upgrade globally, the bathtub,spa and shower markets are experiencing steady growth—driving widespread demand for replacement parts and customized solutions.
Hydrorelax's product main range spans across bathtubs, spas, and shower rooms, offering a variety of components including spa covers, water pumps, heaters, spa pillows, shower rollers, and bathtub pipes, etc.
In today's highly competitive market, standardized products are no longer sufficient to meet the increasingly diverse needs of global buyers. That's why Hydrorelax goes beyond supplying components—we've developed a multi-tiered customization system, ranging from visual OEM to system-level ODM solutions. This empowers our partners to achieve faster market recognition, enhanced product functionality, and greater brand value.
OEM: Visual Identity
Without altering the product itself, your brand identity can be quickly integrated through basic logo printing, standard color application, and packaging design—this is OEM, the most direct and cost-effective form of product branding, ideal for bulk orders and rapid market launch. Hydrorelax offers a variety of OEM services across different categories, including bathtub components, spa , and shower room components & accessories.
Custom Logo Marking
Through custom labels and engraved nameplates, your brand identity can be prominently, clearly, and permanently displayed on products, highlighting both brand presence and aesthetic differentiation. We offer a variety of marking techniques suitable for diverse surface materials across bathtub components, spa components and peripherals, and shower enclosure accessories.
1.Screen Printing
Principle: Screen printing transfers ink onto surfaces through a mesh stencil, followed by natural or UV curing to form a durable pattern.
Effect: Long-lasting, wear-resistant, and water-resistant with excellent color retention, making it ideal for outdoor and humid environments.
Common Applications: Spa covers, spa steps, bathtub and spa control panels, and plastic housings of controllers.
It can also print custom images and QR codes.

2.Inkjet Coding
Principle: Tiny ink droplets are ejected through nozzles onto the surface to form text or patterns.
Effect: Clear printing, high production efficiency, and flexible printing of specifications and batch numbers, suitable for large-scale assembly lines.
Common Applications: spa and bathtub hoses, PVC pipes, and similar components.
3.Nameplate Sticker
Principle: Through processes such as screen printing, digital printing, heat transfer, or etching, the brand pattern is precisely transferred onto plastic or metal substrates, then coated with a protective layer to create a durable, adhesive nameplate.
Effect: Offers a variety of textures and colors, with excellent wear and fade resistance, enhancing brand recognition and a premium look.
Common Applications: Logos and product information display on components such as water pumps, air blowers, ozone generators, and controllers.
4.Other Logo Printing Methods
In addition to the common techniques mentioned above, we also support UV printing, laser engraving, and other logo marking methods.
Whether it's bathtub, spa, or shower room accessories, anywhere visible and suitable for processing, your brand identity can be perfectly showcased.
We welcome you to provide us with your detailed requirements.

Color Customization
Hydrorelax products generally come with a ''standard color palette'' that allows you to make quick selections. These colors and patterns have been market-tested to ensure that the product's appearance aligns closely with brand recognition, without altering core elements such as materials, production processes, or surface treatments. This approach enables rapid implementation and consistent presentation of your brand's visual identity without adding extra development costs—especially suitable for mass production and entry-level OEM customization.
Please note that color customization for components is subject to a minimum order quantity (MOQ). For example, pump color customization requires an order of at least 300 sets. For more detailed information,feel free to contact us!

Product Upgrades
Hydrorelax does not view product issues as isolated defects but as opportunities for innovation. Through ''customized upgrades'' we develop tailored improvement solutions based on pain points and needs revealed during actual use, ultimately creating universal optimizations suitable for the entire market.
1. Optimization Suggestions from Engineers
For older temperature and lighting control systems, Hydrorelax's professional product engineers adopted new sensors paired with temperature displays. This solution achieves perfect compatibility with legacy systems through standardized interfaces and modular designs, making replacements easy. Additionally, with high-precision detection, intelligent recording, and bi-directional linkage between temperature and lighting control, it comprehensively enhances device performance and user experience.
2. Feedback from Users and Clients
Long-term use and placement in extreme outdoor environments caused weakening of the PVC body of the air jets, resulting in unstable bubble output. We promptly initiated a professional upgrade program, fully replacing the PVC material with 304/316 stainless steel, significantly improving nozzle stability under harsh conditions. Building on this success, we have promoted the upgrade to other products with similar material issues.
Advanced ODM: System Solutions
This is Hydrorelax's unique service advantage, thanks to our extensive product categories, professional engineering mindset, and profound experience. We firmly believe these are the key reasons why we are chosen and remain irreplaceable.
