Final answer:
A bathroom with a separate tub and shower is called a full bath. It signifies a bathroom that has a toilet, sink, bathtub, and separate shower as its key components.
Step-by-step explanation:
When a bathroom has both a separate tub and shower, it is referred to as a full bath. These terms help to describe different types of bathroom layouts and features. A full bath typically includes four key components: a toilet, sink, bathtub, and a separate shower. On the other hand, a three-quarter bath usually includes a toilet, sink, and a shower but no tub, while a bathroom suite is a larger space often including a full bath and additional luxury features or sitting areas. A bath-and-a-half generally denotes one full bathroom plus a second bathroom with just a toilet and sink.
