I'm new at this...sorry. I have a vanity just shy of 6', with a 12" high soffit that is 29" deep. The vanity is 24" deep on two outer cabinets and 21" deep in center. Outer cabinets have countertop cabinets 18" wide and 15" deep. Center will have full mirror with two sconces at about 60" high. Not sure where to put recessed lighting in soffit, how many or what size they should be. If putting over countertop cabinets (15" deep) they would have to come out and not be centered. Any help would be much appreciated.

two sinks? are the out lets for the sconces above the sink or off to the sides? where are the upper cabinets going, on each side or in the middle? can you remove the soffit?

One sink, sconces installed at about 60" high through the center mirror which is about 30" wide, upper cabinets on each side of center mirror. Upper cabinets have trim that will butt up to soffit.

i wish you had a picture of this space, is this what it looks like?

Sorry right now there's nothing there. Demo began yesterday. We're now talking about removing soffit. They think it can be done. Your pic looks close, but mirror would cover entire space in center and have one single sconce on each side. They would be about 60" high.

that is great lighting for a 30'' mirror. i would put one recessed can centered over the sink on its own switch if you can.

if you can take it out, it will just be less to deal with, from what i can see you are going to have plenty of light for a 30'' mirror.

Thank you very much for the input. Very helpful!
