I'm desperate for this info, too. Help!

HI --- Good bathroom lighting should light the your face when at the mirror --- if it can not be at the sides then down lights over the mirror. Then general lighting for the rest of the space and a water proof light in the shower if needed. A night light under the vanity if the vanity is elevated. And - everything on DIMMERS.

I totally understand actully what you say.

I Understand. That's a common concern with my clients. But if you choose to have a 3-inch false ceiling, it will not kill the height. you need a minimum of 3 inches for the electrical conduits to pass. And as for the unhygienic environment, it is only created if you have a tray ceiling for cove light. If you install a plain ceiling after a thorough cleaning, there will be no hygiene problem. I hope this helps you all the best
