ᐅ Bathroom lighting design with ceiling spotlights

Hello,

here is my first draft for the lighting design of my bathroom. The main idea was to achieve a symmetrical layout with wall distances of 60 cm (24 inches). I am considering spotlights with a beam angle of 65°. With a luminous flux of 500 lm per spot, I get an undimmed value of 400 lm/m² (37 lm/ft²).

I am unsure if the arrangement is ideal:
- The toilet and bathroom users are illuminated directly from above
- Is a 60 cm (24 inches) distance from the mirror problematic?
- Users at the washbasin might also be illuminated directly from above
- Are ceiling spots with a diameter of 68 mm (2.7 inches) suitable for bathroom areas, or are there better alternatives?

The floor plan is 3.8 m x 2.8 m (12.5 ft x 9.2 ft), so about 10 m² (108 ft²).
The walk-in shower is separated by a wall 2.2 m (7.2 ft) high. On top, there is an RGBW LED strip installed. At the toilet/bathtub area, there is a knee wall about 1 m (39 inches) high.
The vanity is 160 cm (63 inches) wide. Above it, a mirror of the same width with LED circular lighting is to be installed.
The bathroom already exists; now the lighting is to be installed in the suspended ceiling.
All light fixtures are powered by ballasts controllable via DALI.

And I fully agree with Climbee... separately switchable.
In my small bathroom (4.5 m² (48.4 sq ft)) I have spotlights above the shower area and mirror lights on the mirror… each can be switched separately or both turned on together.

And regarding the distribution, I agree with Müllerin.

I can’t find any with CCT from Ansorg. I found some from Deko Light. They have 24V, 64 and 95mm (2.5 and 3.7 inches) diameter. Why choose larger fixtures and where would you position them?

Basically, you can get any model from Ansorg with DALI light control – no problem. The manufacturer mainly specializes in professional lighting.
A light source with a larger diameter can deliver the same amount of light with less glare and create a very nice wide beam without donut holes or other unpleasant light pattern effects.
Check out the Ansorg Coray CMR. Unfortunately, ours aren’t installed yet, so I don’t have any pictures.
By the way, they’re not very expensive – just over 100€ plus VAT and the DALI module. Three of these would be enough, plus one damp-rated fixture in the shower.

The Ansorg Coray CMR require 170mm (6.7 inches) of space above; I haven’t lowered the ceiling that far. Also, you need to choose a fixed light color.

I installed fixtures with CCT throughout the whole house, allowing me to adjust the color temperature during the day. I don’t want to give that up in the bathroom.

The spotlights aligned with the door in front of the mirror are really misplaced. You need lighting above the washbasin, in front of the mirror. When entering the bathroom, you shouldn’t be illuminated from above.
