I built this mini bar for a friend. The electric heater niche was empty, and it seemed like a great idea.
The body is 19mm structural plywood, sanded and finished with wipe-on polyurethane. The face frame and the doors are made of some recycled Pacific Maple I had laying around the shop, finished with hardwax oil. The back mirror and the glass in the doors are acrylic.
The overall depth of the niche is 180mm. The cabinet effective depth is 150mm. The doors are inset into the face frame, which is 19mm thick.
All the joinery of the box and the face frame is pocket holes, while the doors were made using a router and stile-and-rail bits.
I ordered the polished-brass snake hinges specially. The door handles are also polished brass.
