ᐅ Safe Electrical Installation in the Shower

.... I love brightness and would like to have a light fixture above the shower.
It is clear and sensible that electricity and water must be kept separate.
My plan is to cover the electrical components – including the LED bulb – with an acrylic glass enclosure, so that even if someone directs the shower spray upwards, there would reliably be no contact.
Does anyone know where I can find the regulations, or how I can find out exactly what is actually prohibited?

I wouldn’t choose a very small spotlight with a narrow beam angle; it just creates shadows and causes glare.

He needs it for his mirror setup anyway.

I don’t really understand all the fuss. You can just install any lamp on the ceiling. Unless you have a steam shower with jets shooting from bottom to top, nothing really comes into contact there...

You’re not aiming the beam directly at it anyway. It also seems there are no children (anymore)...

I am less concerned about the safety of someone showering than about the regulations, which, as mentioned above, I want to comply with as much as possible.
The electrician who installed the system said that a “regular lamp” in the spot above the shower is not allowed.
To avoid having to get a definitive answer on this issue, the idea of using a reflector would be a simple solution, and personally, I think it would be fun—if it provides usable light.

The way I imagine it now, the spotlight itself would barely be visible. It would be installed so that it can’t be looked at directly and would shine onto a matte reflector—a flat, spherical segment-shaped disc that becomes the actual light source.
How the lights and shadows will actually look, I can only judge once it is installed.
Whether I try this depends on finding a spotlight that “fits”: small, bright, focused, and with a replaceable LED.

This is covered by DIN 57100/VDE 100 Part 701, which distinguishes four zones:

Zone 1 – Area above the bathtub or shower tray
This zone includes the spaces above the bathtub or shower tray up to a height of 2.25 m (7 ft 5 in) above the floor. Within a radius of 60 cm (24 inches) around the showerhead or bathtub/shower tray, light fixtures must be at least rated IP X5 (protected against water jets).

Well, maybe this will help.

I have two spotlights in the shower operating at 230V. Since my electrician (from the general contractor) was not very skilled, he simply ran a cable to the fixtures to bypass the issue, and I connected them myself to the light switch / spotlights. The spotlights have an IP44 rating. They are installed at about 2.5m (8 ft) height, with the terminals and cables well hidden in the drywall ceiling. The spot itself is well sealed and covered with a glass shield; the housing fits relatively tightly. The only potential weak point I could identify is a very small gap around the ring.

However, I still plan to convert these two spotlights to low voltage with a transformer—better safe than sorry. You never know when the kids get older and start using the shower if they might come up with some unsafe ideas...

By the way, the beam angle is 120°, which I find better than, for example, 30°. It provides a more pleasant light, especially since it illuminates the walls higher up / the light reaches further up.

Sounds good 🙂

Any photos available?

That way, it's easier to picture it.

Stay away from this. Only 12 volts with an external power supply located outside the hazardous area should be used in the shower.

In the shower, you are perfectly grounded, your skin is softened, and the resistance to electrical current is very low. This alone makes a 230V supply very likely to cause a fatal electric shock.

Such a shock causes muscle contractions, leading to slipping, falling, hitting your head, breaking bones, and so on.

Anyone who installs a 230V lamp in the shower might as well dry their hair with a hairdryer while in the bathtub.

PS:
You should not rely 100% on the residual current device (RCD, also known as a ground-fault circuit interrupter, GFCI). Even if it prevents ventricular fibrillation, a fall in the shower can lead to a head injury so severe that you may never get back up.
