Fast and Reliable LED Seal Solution for Bathtub Systems
We recently received feedback from a well-known bathtub manufacturer in Lithuania. After installing a batch of our bathtub kits, they asked to adjust the mini LED light seal to better fit their tub design.
With years of experience and strong technical know-how, our team quickly reviewed the request, confirmed the materials, and shipped the updated parts in no time.
In the end, we provided an L-shaped gasket solution that fit their structure perfectly. This case might give you some useful ideas for improving your bathtub lighting.
Bathtub Project Details
This Lithuanian client is a leading local tub manufacturer with high standards for looks, waterproofing, and assembly details. For a recent order, Hydrorelax supplied components like tub pillows, metal handles, mini LED light kits,etc.
During installation, the client told us:
"We have problems with LED and need to change the seal. We had sample with this type of seal."
They wanted the LED units to use a seal type they were familiar with, the same as in their previous sample, to match their existing design. Their feedback was quick, clear, and even included diagrams and sample photos.This showed us it wasn't a quality problem, just a small design adjustment.
Compatibility Challenges
Even though mini LED lights are designed for the same waterproof function, small structural differences exist between manufacturers. These differences often come from:
Installation angle and fit
Tub edges vary slightly by maker. Even small differences in LED hole slope, corner radius, or surface thickness can change how well the gasket fits.
Flat gasket vs L-shaped gasket
Our original gasket was flat and round, fitting most standard tubs. But the client wanted a tighter seal, one that could press firmly in both vertical and horizontal directions to block water more effectively.
Humidity and material expansion
Some European areas have higher humidity. Rubber with a slightly lower expansion rate can create tiny gaps over time in hot water. These factors affect the seal.
Our Fix and What We Did
After reviewing the client's sample photos, our engineers measured and compared them with our current designs.
By comparing, we found that the gasket the client needed has a vertical edge that fits flush against the tub wall, while the horizontal part presses onto the LED base, improving the seal and reducing the risk of leaks.
Luckily, Hydrorelax already had L-shaped gaskets with matching specifications, allowing us to quickly provide the perfect solution.Then we produced a small batch from existing molds, tested them, and shipped within two days. Tests confirmed IPX waterproofing and full suitability for installation.
This adjustment helped the client complete their replacement smoothly and also improved our LED component database. Future product matches can now be done faster and easier.
Better Experience with the Update
After getting the L-shaped gasket, the client quickly tested installation. The results showed clear improvements:
Better fit
The L-shape lets the gasket fully touch the tub curve, no extra adjustments needed.
More stable waterproofing
The vertical and horizontal seal stops moisture from reaching the LED.
Faster installation
Workers can follow the original assembly process without moving holes or adding extra sealant.
The client wrote back:
"The new L-shaped seal fits perfectly with our bathtub design and installation process."
This feedback showed we were on the right track. The client also plans to use this seal type as the standard for future LED kits, strengthening their partnership with Hydrorelax.
Tips for Bathtub Component
For bathtub brands, system integrators, or OEM partners, LED waterproofing might seem small, but it directly affect the end-user experience. From this case, we suggest:
Set seal standards early
Decide on gasket shape and material hardness during the sample stage. This avoids repeated adjustments after mass production.
Test in real-life conditions
LED in tubs face hot water and humid air over time.It's essential to conduct durability tests that replicate real operating conditions, not just standard waterproof tests.
Keep open communication with suppliers
Sharing information between suppliers and manufacturers helps spot design differences and find the best solutions faster.
Focus on continuous improvement in materials and craftsmanship
New silicone materials or dual-injection molding can boost sealing reliability. Staying updated helps extend product life.
Choose responsive, flexible suppliers
Good suppliers deliver on time and can adjust to needs. Fast adaptation is key for projects with multiple batches or different designs.
Mini LED Light Buying Tips for Bathtubs
For bathtub OEM/ODM manufacturers or brand clients, picking the right mini LED isn't just about looks or lighting,it also affects reliability and maintenance costs. Based on years of experience, Hydrorelax offers these quick tips:
| Key Point | Recommended Standard | Notes / Advice | Common Mistakes |
| Seal design | L-shape or double-layer gasket | Fast-response, custom-sample capable | Focus only on lamp body, ignore seal type |
| Material | Flexible silicone or other high-quality sealing rings | Good heat resistance and anti-aging for long wet/hot use | Hard materials like PVC can fail |
| Installation | Thread + gasket combo | Easy to install, easy to replace later | Glue-based installation is hard to maintain |
Waterproof rating | IPX6 or higher | Handles tub overflow and short-term immersion | Only checking IPX4 or lower |
Light & driver | Low-voltage (≤12V) constant current | Safer and keeps brightness stable | Ignoring current control can cause dimming |
Supplier support | Fast-response, custom-sample capable | Quick adjustments if issues appear | Price-oriented purchasing; lack of technical support |
