No power in master bath
Look around for a tripped GFCI - or just press the reset buttons on any GFCIs you can find.
Also, TRY turning the correct breaker (hopefully they are properly labelled, if not, correct that this week) off and then back on - sometimes they don't &quot;look tripped&quot; but they are. (or was that what you meant by &quot;turning everything off and back on again&quot; - not clear where you did that.) If it's a GFCI breaker, try the test/reset on it as well.
The GFCI may not be in the bathroom - people make odd choices when laying things out sometimes. It might be in another bathroom (since you can share a bathroom circuit) or some other room entirely.
