If you are looking for a house to buy you may want one that has more than one bathroom. You may find a listing for a home that has two bathrooms only to find that one of the bathrooms is a 1/4 bath which consists of a shower in the basement.
It is helpful to understand bathroom definitions.
A full bath, which counts as one bathroom has a shower, tub, toilet, and sink.
A three-quarter bath has a toilet, and a sink, and a shower or a tub and counts as one bathroom.
Most half baths sometimes called a “powder room” have a toilet and a sink and counts as one bathroom.
Quater baths which also count as one bathroom may have a toilet, or a sink, or a shower, or a tub.
In the older parts of the city quarter baths in basements are more common than they are in other parts of the region.
The most unusual combination of baths I have ever seen in a house was one where there were a tub and a sink on the second floor and a toilet and a sink on the first. That house had 2 half baths and was listed as having two bathrooms.
Bathroom definitions are likely local so don’t take this too seriously if you are house-hunting outside of Minnesota.
