How To Install Waterproof Shower Niche Lights (LED)
How to Choose LED Strips for Bathroom Niches
Picking the right LED strips for your bathroom niche isn’t just about aesthetics – it requires careful consideration of waterproofing, lighting quality, and compatibility with controls. Bathrooms are humid and wet, so you’ll need LED strips specifically designed for these conditions. Let’s break it down, starting with waterproofing.
Waterproof Ratings: What You Need to Know
The IP (Ingress Protection) rating is key when it comes to bathroom lighting. This two-digit code tells you how well the LED strip is protected against dust and water.
For bathroom niches, go for LED strips with a minimum IP65 rating. The first digit (6) ensures the strip is completely dustproof, while the second digit (5) means it can handle water jets from any direction. If the strip will be exposed to direct water contact, look for IP67 or IP68 ratings for added durability.
- IP67: Handles submersion in up to 3.3 feet of water for 30 minutes.
- IP68: Designed for continuous submersion beyond 3.3 feet.
For example, Thunder Bunny’s shower niche LED kits are built specifically for wet environments and provide long-lasting reliability. Make sure the LED chips are sealed with a smooth, uniform silicone coating. Avoid strips with uneven or thin coatings, as they can let water in and fail prematurely.
Choosing the Right Color Temperature and Brightness
The color temperature of your LED strips, measured in Kelvin (K), can greatly impact the atmosphere of your bathroom.
- Warm white (2700K-3000K): Creates a cozy, spa-like vibe.
- Cool white (5000K-6500K): Offers bright, crisp light for tasks like grooming.
- Neutral white (4000K): Balances functionality and comfort, making it a popular choice for modern bathrooms with white or gray tiles.
When it comes to brightness, measured in lumens per foot, the right level depends on how you’re using the niche lighting:
- 150-300 lumens per foot: Ideal for accent lighting that’s noticeable but not overpowering.
- 100-150 lumens per foot: Great for ambient lighting or nightlights.
For ultimate flexibility, consider RGB or tunable white strips. These let you adjust both color and brightness, giving you the option to create different lighting moods throughout the day. They cost more upfront but offer unmatched versatility.
Controllers and Dimmers: Getting It Right
LED strips typically run on 12V DC power, so you’ll need a compatible dimmer system. Avoid using standard 120V AC wall dimmers, as they can damage the strips. Instead, opt for PWM (Pulse Width Modulation) dimmers, which deliver smooth and flicker-free dimming. Look for controllers with at least 256 dimming levels for precise adjustment.
For added convenience, smart controllers are a great option. These connect via Wi-Fi or Bluetooth, allowing you to control your lighting with a smartphone app or voice commands. You can set schedules, adjust colors on RGB strips, and integrate the lighting with your home automation system.
Thunder Bunny’s LED kits are compatible with standard dimmer switches but require a separate light switch installation. This setup makes it easy to control your niche lighting alongside the rest of your bathroom’s electrical features.
When choosing a controller, check its wattage capacity. For example, a 16-foot LED strip drawing 4.8 watts per foot requires a controller rated for at least 77 watts. Always leave some extra capacity to prevent overheating, especially in the warm, humid conditions of a bathroom. Undersized controllers can fail prematurely, so it’s better to err on the side of caution.
Required Tools and Materials
Before diving into the installation, gather everything you’ll need to make the process as smooth as possible. Having the right tools and materials on hand can save you from those frustrating mid-project trips to the hardware store. While many of these are common household tools, a few specialized items will help ensure a polished, professional-looking result.
Basic Tools List
Start with a measuring tape to get precise dimensions for your niche. For cutting LED strips, use scissors or wire cutters specifically designed for the job – regular scissors can damage the copper contacts. A level is essential to ensure mounting channels are straight, which helps achieve even light distribution.
For surface prep, have cleaning supplies ready, like isopropyl alcohol (70% or higher) and lint-free cloths. Clean surfaces are key to ensuring the adhesive on mounting channels and LED strips sticks properly. If your installation involves screws, grab a drill with bits and a screwdriver set for secure connections.
Safety is a priority, so include a voltage tester or multimeter to confirm the power is off before working with electrical components. If you’re working in tight spaces, like bathroom niches, a flashlight or headlamp can significantly improve visibility. Don’t forget safety gear – wear safety glasses and rubber gloves for added protection.

Installation Steps
With your materials and tools ready, follow these steps to properly install your LED strips. Careful preparation and attention to detail will help you achieve a polished, long-lasting result.
Testing and Measuring First
Before committing to installation, test your LED strips. Connect them to the power supply and controller to confirm they light up and respond to dimming controls as expected.
Next, measure the niche with precision. Use a measuring tape to account for corners, edges, and any obstacles that might affect placement. Determine how much strip you’ll need for each section and mark the cutting points on the LED strips. This step helps minimize errors and avoids wasting materials.
"You can see here there’s a positive and negative terminals right here on my finger positive and negative and so that’s where the wire attaches so on these strips you can actually cut at any one of these junctions right here where the copper terminals are." – Isaac Ostrom, Tile Expert, O. Tile
Cut the strips only at the designated copper junctions, which are typically spaced at regular intervals (often every 12 inches). Cutting elsewhere could damage the strip. Use sharp scissors or electrical wire cutters to ensure clean, precise cuts.
Once your strips are ready, prepare the surface for a strong adhesive bond.
Surface Preparation
Begin by thoroughly cleaning the niche. Use isopropyl alcohol and a lint-free cloth to remove dust, grease, or residue, especially in corners and edges where debris tends to accumulate. A clean surface is crucial for the adhesive to stick properly.
Make sure the area is completely dry before moving forward – any lingering moisture can interfere with adhesion and cause the strips to peel over time. If the niche was recently tiled or grouted, allow at least 24 hours for curing before proceeding.
For textured surfaces, lightly sand the area with fine-grit sandpaper (220 grit or higher) to create a smoother surface for the adhesive. After sanding, remove any remaining dust to ensure a clean application.
If you’re using mounting channels like the Schluter DECO-SG Profile, this is the time to install them. These channels not only give a polished, professional look but also provide added waterproofing and make replacing the LED strips easier down the line.
Installing and Connecting LED Strips
Start at one end of the niche and work methodically toward the other. Peel off only a small section of the adhesive backing – about 6 inches at a time – to maintain control as you position the strip. Once adhered, repositioning the strip is difficult and can weaken the adhesive.
Press the strip firmly along its length, paying extra attention to corners and edges to ensure it stays securely in place. If you’re using mounting channels, make sure the strip fits snugly without any gaps or bulges.
For connecting sections of the strip, consider using Thunder Bunny’s IP67 quick disconnects. These waterproof connectors snap together securely and can be easily disconnected later for maintenance or adjustments. Always double-check that the positive and negative terminals align correctly; reversing the polarity could damage the LEDs.
When navigating corners or making turns, avoid sharp bends that might harm the internal wiring. Instead, cut the strip at the nearest copper junction and use a connector to bridge the gap. This approach maintains the strip’s electrical integrity while allowing it to contour smoothly around the niche.
Once the strips are in place, move on to wiring and final testing.
Wiring and Final Testing
Connect the LED strips to the dimmable power converter, carefully following the polarity markings. Thunder Bunny’s 24V system is forgiving, but incorrect wiring can still cause issues. Double-check all connections before powering up.
Route the wiring through dry areas and keep connections away from potential water exposure. Install the power converter in a dry, easily accessible location, such as under a vanity or inside a nearby cabinet. This placement ensures safety and makes future maintenance simpler.
Test the system by turning the lights on and off several times and adjusting the dimming controls. Check that all sections light up evenly and address any flickering or dark spots while the connections are still accessible.
Finally, use a voltage tester to confirm that all connections are secure and free of shorts. This step ensures your installation is safe and ready to withstand the humid bathroom environment.
