I had my electrician put a plug inside the cabinet, on the wall behind the pull-out. Then we mounted a surge protector on the back side so the client has a sufficient supply of plugs. The cable from the wall to the cabinet is on a coil so it doesn't interfere with closing the pull-out. I hope this information is helpful.

Perfect solution! Thank you.

You're welcome. Here is another application with a different cabinet configuration. This is a great way to store those ugly electric toothbrushes. Now if someone could come up with a built-in waterpik, counters would totally free of hygiene devices!

You're good--

Thank you. I try to create functional and aesthetically pleasing spaces that maximize the use of the space.

Was this a custom built cabinet?

Yes, it was.
