ᐅ Are electrical cables allowed to be installed under a shower?

Hello everyone,

we are currently building, and the electrician has installed a cable under our shower. The cable then runs up through the shower wall and through the exterior wall (outdoor light).

Now I’m wondering if this is actually allowed?
The electrician says it is.

So the cable lies on the base slab.
There will be screed and insulation on top of it, and plaster and tiles on the wall.
(The cable is chased into the masonry.)

So what? What is the objection?

I’m still not quite sure what to make of this. The cable runs along the floor, and the shower will later be installed on top of it. Now the cable goes up the wall, chiseled into the masonry, and this wall is directly inside the shower area?

Yes, it goes up the wall, channeled into the exterior wall (Ytong), then through the outer layer.

This means it will be filled in, then covered with 15 mm (0.6 inch) of lime-cement plaster, plus tiles. The shower will be installed there.

and that is completely safe. The cable is insulated. There is plaster over it. Tiles on top... just think about it.

An electrical outlet has no place in a shower; the cable is completely irrelevant.
