A half bathroom is a bathroom with a toilet and sink , but no bathtub or shower. It’s also commonly called a powder room or guest bath.

What It Includes

  • Toilet.
  • Sink.
  • No bathing fixtures like a tub or shower.

Where You Usually See It

  • Near a home’s entry or main living area.
  • On the first floor for guests.
  • In smaller homes or additions where space is limited.

Why It Matters

A half bath is useful because it gives guests a convenient restroom without using a full bathroom. In real estate listings, it’s often counted as part of the total bathroom number, so a home described as “1.5 baths” has one full bathroom plus one half bath.

Simple Example

If a house has a master bath with a shower and tub, plus a small bathroom near the hallway with only a toilet and sink, that hallway bathroom is the half bath.

Bathroom type Typical fixtures

A half bath is basically the **smallest practical bathroom setup** for handwashing and restroom use.
