Spots in the wall panel in front of the bathtub

Hello everyone, after selecting the sanitary fixtures and chatting with the consultant, my wife came up with the idea that spots could be integrated into the bath panel, which will be tub-high and about 15cm thick, that would emit indirect light upwards. I can imagine it looking nice, but I have concerns regarding the moisture. Please discuss! :o) Regards

... spots could be integrated into the front panel of the bathtub, which will be as high as the tub and about 15cm thick, that basically emit indirect light upwards.

Sounds to me like direct light and glare. Have your wife google "Schutzbereich Bad".

everything is possible:

Within a radius of 60 cm around the shower head or bath or shower tray, the luminaires must have at least the protection class IP X5 (protected against water jets).

Even in the tub:

Only luminaires with protection class IP X7 (protected against the effects of immersion) may be used here.

Let your wife google "Schutzbereich Bad".

Command retracted.
Someone already did that.
