We have the 3 door 48” x 32” model .which were recessed. That required taking out studs and building a 2x4 frame with a 2x6 header to transfer the weight bearing. 

 We love the look and functionality. The inside and outside lights and inside and outside mirrors are beautiful. 

Design changes I’d make are
 1. Make the inside lights dimmable for night time.
 2. Make the color temperature of the lights adjustable from the 5K supplied. I’d like to make them closer to 3K like the other LED 
lighting I’m installing in the ceiling. 
 3. Make the controls on the front dimmable because they are too bright at night. 

Overall we love the product.
