We have a very small main bathroom. It used to be covered in a floor to ceiling mural, had a deep but small tub enclosed in glass (so claustrophobic!) and carpet on the floor (why???).
We worked with the small footprint and incorporated a few tricks to make the room feel light and bright as possible.
In keeping with the rest of our home, we wanted the bathroom to be an updated vintage look. Things like the decal (from Etsy seller Elephannie), the bridge faucet, and the traditional subway tile walls added traditional character. We mixed them with more modern elements like the marble floor tiles and oversized shower head.
