I am currently facing the challenge of arranging LED ceiling spots for two small bathrooms (each about 4 square meters (43 square feet)).
The lights each have approximately 500 lumens, which should be sufficient for that size, right? I have often read that around 250-300 lumens per square meter are recommended. Additionally, each bathroom will have an illuminated mirror that can be turned on separately.
The following plan is the electrician’s layout. The bathrooms appear larger on the plan than they actually are, just under 4 square meters (43 square feet).
From our perspective, the LEDs are placed too far to one side. Our idea would be to position the spots centrally, so closer to the middle towards the sink and shower.
The first spot should probably remain centered over the sink, correct?
What do you think?

Thank you for your support.

Additionally, in bathroom 2, the spotlight is exactly at the height of the window, where natural light already enters. In contrast, next to it at the height of the shower, there is no window light.
I also forgot to mention that the spotlights are about 15 centimeters (6 inches) wide and have a wide beam angle.

Is there a mirror above the sink? Is there no lighting planned specifically for this mirror?
If not, I would try to position the spotlight as close as possible above the sink. Place the second one directly in the shower. Not everyone has that.

the spotlight is exactly at the height of the window, where light already comes in anyway.

Thank you for your support. I would like to. But honestly, with 4 sqm (43 sq ft), it’s not so much about lighting a dark corner, but rather about placing such an outlet exactly in line—either centered above the door, along the room’s diagonal, or at the shower edge—so that it visually harmonizes on a small ceiling area. Your drawing is too rough and, with the window and door, basically represents 12 sqm (129 sq ft) or more.
