I'm remodeling our bathroom and I'm putting up a larger mirror. The larger mirror covers an unneeded outlet for my needs. I'd still like to keep the outlet in case I decide to get a smaller mirror, need the outlets, or sell the house though. I originally figured the easiest way to deal with this is a blank wall plate. However, the ones I'm finding seem to protrude out too much so the mirror doesn't look flush against the wall.
Are there flat wall plates? If not, how would you suggest going about this? My other idea was simply cutting and painting a thing piece of plastic but it seemed janky.
