I have a new bathroom, and I bought a new light to go above vanity. I have an old-work circular box and was just about to cut the circle in the wall when I reviewed a pre-drywall picture and realized that there is a stud dead center of where I need to mount this light. Therefore, putting the circular box in place is impossible. Moving the light is also impossible. How can I mount it to code; what's the proper approach (other than planning properly when I built the wall)?

Thanks!

 

Perhaps a pancake box.

More characters.

 

Yup, Pancake box. They come in plastic or metal. Either will work. Screw the box to the stud.

 

Thanks guys, I just looked up what those are and it's definitely the solution

 

Here is an old work pancake box for when there is no stud. Why didn't I think of this?

3-1/2" Round 1/2" Deep, Pan Box with (5) 1/2" Conduit Knockouts and Old Work Ears

Sorry, about no image, but it has a flat plate behind the box that extends out past the hole. You just angle it in and center the box.

 

there is also this if you need more room for wires.
