Replacing old recessed medicine cabinet
I have an old, rusted recessed medicine cabinet with odd dimensions. Inside is 26.5 w by 16.5 h. Measurements from outside are 28.75 w by 18.75. Above the medicine cabinet are 4 vanity lights separately installed. Ive tried to find a replacement with same or similar dimensions. It has sliding mirror doors. I don't want to make it a major expensive installation as i Can't find a replacement with same dimensions at Lowes, Home Depot, Amazon or Menards. Id Like to avoid cutting more into wall as electrical outlet is very close to left of cabinet. What are my options?
