Carpentry, lowering baseboard.

The outlets are 12 inches off the floor. The base is 14 inches high. This house was built in 1900s and God knows when the electrical boxes were installed.

I didn't hang the boxes, didn't pick the base, I'm just working with what I've got.

Ripping the base is not ideal because in the areas where there are no outlets the base would have to be short there to.
