Providing power to the oven often involves holes in the floor/wall, which breaks the kitchen aesthetic to have a massive pipe coming in to deliver power. It would be nice if the power could be plumbed to the floor (either immediately below the oven, or to some other tile of the multiblock floor).

Current workaround: using entangled blocks from the Entangled mod

A lot of cable/pipe mods have support for facades one way or another, which I believe is the better solution than reinventing the wheel in Cooking for Blockheads for the sole purpose of the electric oven upgrade.
