Correction for The Spruce
Hello - firstname.lastname@example.org
In this article you mention requirement of 2 dedicated circuits for bathroom:
This does not appear to be true, there is an exception where everything can be on a single dedicated breaker (circuit) (as long as that circuit serves nothing outside of the bathroom). This is from https://www.ecmag.com/section/your-business/article-210-branch-circuits-2 or from https://www.hunker.com/13725552/electrical-code-for-bathroom-lights-a-homeowners-guide.
This is worth correcting, because the cost difference in wiring the 2 dedicated circuits compared to one can be substantially higher - if one cares about installation/labor costs.
