Medicine cabinets are great for storing items you use everyday. Mine don't have lights , but they have power inside and that is where I keep and charge my electric toothbrush. The ones I used in my master bathroom are from Robern 24" W x 48" H.

In my previous house I used a lighted Kohler medicine cabinet in my teen's bathroom.

I'd forget the integrated light and get two frameless mirrored medicine cabinets

a light over each mirror or sconces on either side and between.

storage of daily use items is everything, not to mention a clean countertop.

Start by showing the bath you now have and the plan for the bath : )

Sophia makes a beautiful lighted recessed or surface mount medicine cabinet. We have also installed Kohler recessed medicine cabinets. Trending towards the single mirrored look over each sink lately and it offers more lighting options. Use caution, there may be a need to relocate the vent hidden in the wall.
