Before understanding what a 1.5 bathroom is, I think we need to comprehend what a 0.5 bathroom is.
A 0.5 bathroom is called a half bath. I don’t mean half bath in terms of its size in square feet. A half bath offers a sink and a toilet but no shower or bathtub.
You can use it as a basic bathroom but not to shower, well, unless you can shower in a sink. Half baths are usually for guests, also called powder rooms.
They are mostly located around the corner of the kitchen or under the staircase.
Now that we know what a half bath and a full bath is let’s do simple addition. Full Bath + Half Bath = 1.5 Bathroom. Yes! There it is, we did it.
I hope I have made it easier for you. Now when you scroll AirBnb or Zillow, there should not be any confusion while reading 1.5, 2.5, or 3.5 bathrooms.
Simply consider the number before the decimal point as full baths, and you will be good to go!
