Bathroom lighting has many jobs to do. It needs to feel fresh and clean to get that zing in your step every morning, have the ability to wind you down each night, or make it easy and glamorous to primp for date night.
Try and see daylight and electric light as one scheme in the planning stages, rather than just replacements for one another.
Top-down/bottom-up blinds can filter light can be used with spotlight fixtures, ceiling lights, or vanity lights to change the look and feel during the days and changing seasons. (You’ll need to supplement your sunlight on dark winter mornings, but it will possibly need filtering on full summer sun mornings.)
Privacy is also key here, so look to control the light as well as the visibility rather than plump for standard water-resistant roller blinds (although these can be great, affordable, and tight-space solutions for small spaces).
