This blog gives you a quick look at the market potential of bathtub lights, how to choose them, and how they can make your brand stand out.
Market Potential of LED Bathtub Lights
In the past, bathtubs stood out by jet count, pump power, or massage features. Today, consumers care more about visual and sensory experience. With lighting, a bathtub becomes a space for relaxation, not just cleaning.
1.Design upgrade trend: In Europe, over 35% of high-end bathtubs now feature LED mood lighting.
2.Premium shift: Hotels, B&B，luxury home brands use lighting systems as a selling point.
3.Accessory-driven value: OEM feedback shows adding LED lighting can raise overall product value by 10–15%.
What's Included in a Complete LED Light Kit?
A standard LED bathtub light kit usually includes:
LED Light Body
The light source, available in single color or RGB, with waterproof and corrosion-resistant housing.
Controller
For power, color, and brightness control, operated by button, remote, or app.
Power Supply
Low-voltage converter, typically 12V or 24V for safety.
Waterproof Connectors & Sealing Rings
Keep the light fully sealed to prevent leaks.
Optional Modules
WiFi or Bluetooth for smart control
Music sync for lighting effects
Fiber extension for larger tubs or room lighting
Different brands may vary slightly in structure, but the core logic remains the same: lighting, control, power, and waterproof protection.
How to Choose the Right LED System?
For bathtub buyers, the best lighting system depends on your product positioning.
Here are three common setup options:
Entry Level: Single-Color Light + Manual Control
Ideal for basic massage or budget tubs.
1.Simple structure, easy to install
2.Single-color light (warm or cool white)
3.Low cost and easy maintenance, great for OEM or price-sensitive markets
Mid Range: RGB Light + Remote Control
Best for home brands or hotel projects.
1.Multi-color effects (fade, jump, or fixed color)
2.Wireless remote operation
3.Can link with massage, air, or audio systems
This is the most popular choice in Europe and North America.
High End: Smart Control + Music Sync System
For premium and custom smart bathtubs.
1.WiFi/App control (works with Google Home, Alexa, etc.)
2.Syncs light with music
3.Allows remote scene presets
Perfect for high-margin models or custom projects, helping build a smart brand image.
Make Your Brand Stand Out
A standard product is just the start. Real value comes from differentiation. A reliable supplier should offer flexible OEM/ODM customization to help brands launch tailored lighting systems faster and enhance their unique image.
Custom Options:
| Item | Description |
| Light Color & Control | Single color, RGB, App control, or music mode |
Housing Material & Color | Stainless steel, ABS, or clear PC |
Branding on the nameplate or packaging | |
Cable Length & Connector | Adjustable to fit bathtub design |
Certifications | CE, RoHS, UL, SAA, and more |
Installation and After-Sales Support
In LED bathtub projects, the quality of installation and after-sales support often determines the sustainability of your supply chain. This is not an "extra service" but a key sign of whether a factory truly has system integration capability.
Ease of Installation
A well-designed LED kit should avoid complex wiring or extra sealing. The light body usually features quick-connect waterproof plugs and standard low-voltage interfaces. For finished product importers, this directly affects labor time and after-sales cost. If installation requires too many steps, special tools, or professional electricians, even a low-priced system can lead to higher risks and complaints.
Documentation & Technical Support
Before purchasing, confirm that the manufacturer provides clear installation diagrams, wiring schematics, technical data sheets, and video guides. These not only help assess quality but are also essential for local certifications such as CE or UL.
Maintainability
An ideal design allows easy replacement of the light or cable without removing the entire system. If the light and housing are sealed as one, any damage means a full replacement, raising costs and harming brand reputation.
Factory Testing Process
Most lighting issues occur during assembly, not transport. Reliable suppliers conduct waterproof (IP) tests, temperature aging, and brightness consistency checks before shipment.
Tips:
Beyond price, focus on three key factors: standardized installation, traceable after-sales, and verifiable testing. Meeting all three ensures a stable, long-term partnership.
