From our lighting expert “Designer Erke” with 10 years of industry experience

The bathroom is a place for relaxation and daily routines—yet its lighting is often neglected. However, bathroom lighting plays a decisive role in creating the atmosphere, functionality, and even the perceived size of the space. In this blog, we will reveal how modern bathroom lighting can transform a basic bathroom into a premium retreat. And of course, we will introduce our high-quality IP44-certified lights, which combine safety and style.

1. Lighting in the Bathroom: Defining Functional Zones

A well-thought-out lighting concept should be tailored to the needs of each area in the bathroom—a realization also emphasized by experts from Paulmann and Lampenwelt.

A. Washbasin & Mirror Cabinet: Precision Lighting for Daily Routines

This is where the morning routine takes place—shaving, applying makeup, and skincare. For shadow-free illumination, we recommend:
  • LED mirror lights or built-in light strips above and below the mirror. Tip: Our Tillume IP44 wall lights offer glare-free light with 4000K for true-to-life color reproduction.
  • Ceiling as a basic connection: A central spot with a dimmable function creates flexibility between task lighting and ambiance.
Why 4000K?
This color temperature simulates daylight and prevents “makeup fails” due to overly warm tones—a trick also recommended by Schöner Wohnen.

B. Toilet Area: Relaxation Meets Hygiene

Whether reading the newspaper or cleaning—this area requires multifunctional lighting:
  • A discreet ceiling light with IP44 protection:provides basic brightness.
  • For ambiance: A wall-mounted LED reading light next to the toilet—ideal for nighttime visits without glare.

C. Shower & Bathtub: Wellness with Electricity

Waterproof lighting is a must! Our recommendations:
  • IP65-certified recessed lights in the shower niche.
  • Indirect LED strips along the wall joints for soft accent lighting while bathing. Try our Tillume IP67 light strips—they are easy to install and completely waterproof.

2. Color Temperature & Brightness: The Science Behind the Mood

Color Temperature: 3000K vs. 4000K
  • 3000K (Warm White): Creates a cozy evening atmosphere, perfect for relaxation.
  • 4000K (Neutral White): Optimal for precise tasks like applying makeup—eliminates yellowish tones.
Designer Trick: Combine both color temperatures via smart home control! Activate 4000K in the morning for a fresh start, and dim to 3000K in the evening for a wellness feeling—a concept also supported by Reuter.
Lux Values: How Bright It Should Be
  • Washbasin: 300–500 Lux (comparable to office lighting).
  • Shower/Toilet: 100–200 Lux is sufficient.
Measurement Tip: Use a Lux meter app to identify “dark corners”—a tip also shared by Lampen1a.

3. Choosing the Right Lights for Bathroom Ceiling Lighting & More

A. Mirror Lighting: No Room for Compromise

Avoid ceiling floodlights that cast unfavorable shadows! Instead:
  • Wall lights on both sides at eye level (about 1.60 meters).
  • Tillume IP44 spots as additional ceiling light—waterproof and with a slim design.

B. Shower: Safety First

Use lights with at least IP44 (splash-proof). For shower cabins, we recommend IP65. Our bestseller: The Tillume round housing—impact-resistant, mold-resistant, and with a lifespan of 50,000 hours.

C. Setting Accents with Light Strips

Modern bathroom lighting thrives on layers:
  • Under cabinets: Emphasizes the floor level and creates a floating effect—a trend also picked up by IKEA.
  • Behind mirror edges: Creates a holographic depth.

4. 5 Mistakes That Make Your Bathroom Look Cheap

  • A single ceiling light: Creates a cave-like feeling—always use zonal lighting!
  • Cold white light (5000K+): Appears clinical and uninviting.
  • Missing dimmer: Fixed brightness never fits every time of day.
  • Visible cables: Use wireless LED solutions or recessed installation.
  • Neglected IP classes: Rust stains and short circuits are not decoration!
Note: According to Emero, poor IP classes are one of the most common causes of bathroom accidents.

5. Tillume Solutions: Where Technology Meets Aesthetics

Our bathroom lighting combines German engineering with Scandinavian design:
  • IP44/65 certification: Absolute safety in high humidity.
  • Dimmable versions: Controllable via app or wall switch.
  • Plug-and-play systems: Easy retrofitting without drilling.
Highlight Product: The Tillume IP44 luminaries with spot impress with recessed installation for low ceiling, high light output, and three color temperatures to choose from.

6. FAQ: Important questions about bathroom lighting

Q1: Can I use normal lights in the bathroom?
A: Only outside of splash zones. IP44 is mandatory within 60cm of water sources.

Q2: How do I calculate the required luminous flux?
A: Formula: Room size (m²) x 100-150 lumens = total amount of light. Example: 8m² x 120lm = 960lm. If you choose our 6W or 8W LED Spot, recommend quantity is 2pcs.

Q3: Are LED bulbs dimmable?
A: Yes, our models support PWM Dimming.
