Adding waterproof LED lights for a shower niche turns a simple recessed shelf into a striking focal point while making it easier to find your shampoo in a dim shower. Because the niche sits inside a wet, splash-prone zone, the lighting you choose has to be genuinely rated for moisture and, ideally, run on safe low voltage. Done right, niche lighting is a small upgrade that looks custom and high-end. Done wrong, it is a safety hazard or a strip that fails after a few months. This guide explains IP ratings, light types, safe wiring, and how to install niche lighting the right way.

Why IP Rating Matters Most
The single most important spec for shower niche lighting is the IP (Ingress Protection) rating, which tells you how well the fixture resists dust and water. The rating has two digits: the first for solids, the second for water. For a shower niche you want a high water rating:
- IP65: protected against water jets—good for the splash zone of a niche.
- IP67: protected against temporary immersion—a safe margin for wet areas.
- IP68: protected against continuous immersion—overkill for most niches but ideal if the light could sit in standing water.
Do not use standard indoor LED strip (often IP20) inside a shower niche—it is not sealed against moisture and will corrode or short out. Look for strips or fixtures explicitly labeled for wet or shower use, ideally IP67 or higher for the niche interior.
Low Voltage Is the Safe Choice
Water and electricity are a dangerous mix, so shower niche lighting should run on low-voltage DC power, typically 12V or 24V, supplied by a transformer or driver located outside the wet area. Low-voltage LED lighting carries far less shock risk than line voltage, which is why it is the standard for shower and steam applications. Key safety practices include:
- Use a UL-listed 12V or 24V driver mounted in a dry, accessible spot (an adjacent closet, vanity, or attic).
- Keep all splices and connections outside the wet zone, in a junction box.
- Protect the circuit with a GFCI, as required for bathroom circuits.
- Follow the manufacturer’s instructions and local electrical code; hire an electrician if you are unsure.
Never wire a 120V fixture directly inside a shower niche unless it is specifically listed for that location.
Strip Lights vs. Puck Lights vs. Recessed
There are a few ways to light a niche, each with its own look:
- LED strip (tape) lights are the most popular. Run a waterproof strip along the top inside edge (behind the front lip) so the light washes down over the contents without glaring in your eyes. Choose a strip with a sealed silicone jacket rated IP67 or higher.
- Puck lights give a spot of light and can be recessed into the top of the niche for a clean look, good for a single small niche.
- Recessed mini-downlights rated for wet locations offer the most finished look but require more planning and depth in the niche wall.
For most bathrooms, a hidden waterproof strip along the top front edge gives the best glow with the least glare and the easiest install.
Color Temperature and Dimming
The look of the light matters as much as the fixture. Color temperature is measured in Kelvin (K):
- 2700K to 3000K (warm white): cozy, spa-like, flattering—popular for relaxing showers.
- 3500K to 4000K (neutral/cool white): crisp and bright, closer to daylight, good for a modern look.
- Adjustable/RGBW strips: let you change color for accent or mood lighting.
If you want to fine-tune brightness, choose a dimmable driver and a compatible dimmer, and confirm the LED strip is rated as dimmable. Many homeowners set niche lighting on its own switch or a smart control so it can glow softly as a nightlight.
Installation Overview
Niche lighting is easiest to plan before the tile goes up, but it can be added during a niche build. The general steps:
- 1. Plan power. Decide where the low-voltage driver will live (dry, accessible) and run the low-voltage wire to the niche during rough-in.
- 2. Waterproof the niche with a proper membrane or a pre-formed waterproof niche, sealing around the wire penetration.
- 3. Mount the strip. Adhere the waterproof LED strip along the inside top front edge, ideally in a small channel or behind the lip so the diodes are hidden.
- 4. Seal the wire entry where the low-voltage lead passes through the waterproofing, using the membrane maker’s sealant.
- 5. Connect to the driver outside the wet area and to a GFCI-protected switch.
- 6. Test before tiling over anything, then tile the niche and finish.
Because waterproofing and electrical both matter here, many homeowners handle the tile and hire an electrician for the power side.
Common Mistakes to Avoid
- Using indoor IP20 strip—it will corrode and fail in a wet niche.
- Placing the driver inside the wet zone—it belongs in a dry, accessible spot.
- Skipping the GFCI—bathroom circuits require ground-fault protection.
- Mounting the strip where it glares—hide it behind the front lip so you see the glow, not the diodes.
- Poor waterproofing at the wire—an unsealed penetration lets water into the wall.
Powering Options: Battery, Plug-In, and Hardwired
How you power the light shapes both the install difficulty and the long-term convenience. There are three common approaches:
- Hardwired low-voltage: the cleanest, most permanent option. A driver mounted in a dry spot feeds low-voltage wire to the strip, controlled by a wall switch. Best done during a remodel when walls are open.
- Plug-in low-voltage: the strip’s driver plugs into an outlet outside the wet area. Easier to retrofit but you need an accessible outlet nearby.
- Battery or rechargeable puck lights: no wiring at all—rated waterproof puck lights with motion or touch control stick inside the niche and run on batteries. The easiest retrofit, but you must recharge or replace batteries periodically.
For new construction or a full remodel, hardwired low-voltage gives the most seamless result. For an existing shower where you do not want to open walls, waterproof battery pucks are a surprisingly effective shortcut.
Choosing a Waterproof Strip That Lasts
Not all “waterproof” LED strips are built the same, and the wet, warm environment of a shower is punishing. When shopping, look for a strip with a fully sealed silicone jacket (not just a thin conformal coating), a wet-location or IP67-plus rating, and corrosion-resistant solder points. Choose a reputable low-voltage strip with a good CRI (color rendering index) of 90 or higher so your towels and tile show true colors. Make sure the strip’s cut points and connectors are also sealed, since an exposed cut end is the most common failure point. Pair it with a driver rated for slightly more wattage than the strip draws so the power supply is not running at its limit, which extends its life. Spending a little more on a genuinely wet-rated, well-sealed strip pays off in a light that keeps working season after season instead of corroding within months.
Frequently Asked Questions
What IP rating do I need for a shower niche light? At minimum IP65, but IP67 or higher is recommended for the splash-prone interior of a niche. Standard indoor IP20 strip is not safe or durable in a wet area.
Are LED strip lights safe in a shower? Yes, when you use a waterproof strip rated for wet locations, run it on low-voltage (12V or 24V) power, keep the driver outside the wet zone, and protect the circuit with a GFCI.
Where should the light go in the niche? Along the inside top front edge, hidden behind the lip, so the light washes down over the contents without shining in your eyes. That placement gives the cleanest, glare-free glow.
Do I need an electrician? The low-voltage strip itself is simple, but connecting the driver, switch, and GFCI to the home’s wiring should follow code. If you are not confident, hire a licensed electrician for the power side.
What color temperature is best? Warm white (2700K to 3000K) gives a relaxing, spa-like feel, while neutral white (3500K to 4000K) is crisp and modern. Adjustable strips let you switch between moods.
Can I add niche lighting to an existing shower? It is much easier during a build or remodel because of the waterproofing and wiring, but a skilled installer can retrofit it by opening the niche, running low-voltage wire, and re-waterproofing.
