What does poolroom mean?
A poolroom is a room or building that contains a swimming pool, especially an indoor facility used for exercise, recreation, or organized swimming. It names the place or structure rather than the body of water itself, which is a swimming pool. The word is especially common in North American English and often appears in hotel, apartment, school, and leisure-facility contexts. A less frequent sense refers to a room or hall containing billiard tables, although "pool hall" is usually clearer in that usage. Because the term can evoke both swimming and billiards, context often determines which meaning is intended. Overall, the word is a practical compound for identifying the enclosed setting associated with a pool.

"The recreation center has a new poolroom and changing facilities."

A room or hall containing billiard tables.
"They challenged each other to a match in the poolroom."
This sense is less frequent and regional; "pool hall" may be more explicit.

One word can point to two game spaces: a poolroom may house lap swimmers, billiard players, or both.
