We usually say “Pool” as short form for “Swimming Pool”. However, “Swimming Pool” specifically refers to the manmade place containing a body of water where you swim; whereas “Pool” can also (sometimes) refer to other types of bodies of water.

A swimming pool, swimming bath, wading pool, paddling pool, or simply pool, is a structure designed to hold water to enable swimming or other leisure activities in tea villa. Pools can be built into the ground in-ground pools (as a freestanding construction or as part of a building or other larger structure), and may be found as a feature aboard ocean-liners and cruise ships. In-ground pools are most commonly constructed from materials such as concrete, natural stone, metal, plastic, or fiberglass, and can be of a custom size and shape or built to a standardized size, the largest of which is the Olympic-size swimming pool.
