First of all, a division of the room areas must take place according to the different lighting torques. The bathroom gets the right atmosphere when the lighting is also tuned to the interior. "For this purpose, spatial peculiarities in terms of architecture, color scheme or surfaces should be determined and included in the conception," says the expert.
If you are planning a bathroom completely new, start planning the lighting in good time. Because once the bathroom has been tiled, additional power lines and connections can not be installed as easily.
"Optimal lighting results from different lighting levels with sometimes quite different requirements," says Bolz. Each level has its own function and so ideally, not just a single bulb should be in your bathroom. Because a single light source just can not take over all the functions at the same time.
This base should be bright, so that you can keep the overview in the bathroom. In the best case, a good general lighting in the bathroom replaces the daylight.
A diffuse basic lighting also illuminates every corner when cleaning. "Useful here is the use of particularly bright, evenly lit lamps on the ceiling or in the upper wall area," says the expert.
Tip: Bright colors visually expand a small bathroom. Dark wall tiles or tiles, on the other hand, swallow the light, so that bulbs or more lamps have to be used to strengthen them.
But even in large bathrooms you should not miss lighting on the mirror. Because the light comes only from a practical general lighting from above, when looking in the mirror unsightly drop shadows are thrown under the eyes, nose and chin. Which brings us to the second light level in the bathroom.
Functional light should be aimed specifically at the object to be illuminated, making details clearer, while at the same time creating a warmer atmosphere for the first time. In the area of the mirror, lights with opal glass cover are an advantage, too brighter halogen spotlights or spots rather less. Even illuminated small make-up mirrors with magnifying function are helpful.
In addition, glare-free, linear luminaires above the (large) mirror stretch the space significantly upwards.
For bright, scattered make-up light, however, 300 lux are ideal - but then it is less atmospheric. The remedy here is a dimmer, with which you can control the light intensity depending on your needs.
It is more complicated here by the rules for wet rooms that apply to light. "Particularly around the shower and tub - and also wherever humidity meets electricity - strict regulations must be observed," says Bolz. And you should definitely stick to it - after all, your safety in the bathroom has the highest priority!
In this area, the luminaires should therefore be protected against splash water (protection class IP X4) or jet water (IP X5) and may only be operated with safety extra-low voltage up to 12 volts.
Be sure to ask a specialist. Lighting planners or electricians are happy to help.
"If the on-site opportunity exists, it is attractive to work with niches in the walls. For example, they can then be used as storage and equipped with their own luminaires, "says Bolz. Through the contrasting and expressive light scenery, they not only enliven the overall impression of the room, but also provide the right choice for cozy accents.
If niches are not available, shelves can also be illuminated by indirect accent lighting. You can also use soft spotlights to stage wall surfaces, or an LED strip - just below the tub - attach. Colored light, for example in the shower, gives a bath the look and feel of a spa.
The expert advises against using exclusively accent lights: while indirect light creates an atmosphere, it casts too many shadows and illuminates too few corners of the bathroom.
