In houses I've been in before with similarly places bathrooms, this halfbath is generally for guests, peeing, and basic washing of hands etc. If you're going to blow it up, that's for other places.
You want everyone washing their dirty hands in the kitchen sink?
Tbh that’s probably the confusion with this post, shoulda added the context, but yeah the rest of the photos showed it’s just a toilet, no sink or mirror.
Your aren't, it's all good. I'm just wondering what problems someone could have with this setup. Nothing comes to mind other than not liking small bathrooms.
