@kmkane... The "old thread" comments, at least from ME... aren't for any other reason than letting some contributors know, that the advice they might believe they are giving, may be moot. I know that when I 1st became involved on Houzz, I was glad when someone indicated that I may be addressing a question which had probably been answered months (if not years) ago. Helped me "learn" to check the original posting date before blathering on about an issue someone was no longer interested in.

Medicine cabinets have come along way in recent years. The best option is to get a frameless style and integrate it into a wall of mirror. You can mount sconces thru the mirror on either side of the cabinet. If you have walls on either side of the sink, you can put the cabinets to the side, integrated into mirror again. If you have an open wall in your bath, yo can get an extra tall medicine cabinet to hold loads of stuff. There are loads more on houzz photos. Just search medicine cabinet. Sometimes you have to hunt for the cabinet because they are so well integrated. Robern makes some of the best frameless styles, but there are a ton of others on faucetdirect.com. Many even come with integrated lighting for a very modern look.

This made me laugh: http://www.theguardian.com/environment/2016/jun/09/seagull-turns-orange-after-falling-into-vat-of-chicken-tikka-masala I couldn't copy the picture, but it's hilarious.

Have you tried looking through the Houzz professional's tag or asking the people who have posted the photos that you've seen where they got their cabinet from?
