A 'hot tub' is a large tub filled with hot water, used for relaxation or hydrotherapy. It's essentially a giant, bubbly bathtub for multiple people. It's all about unwinding and enjoying warm water with friends or family. Unlike a regular bath, it often includes jets for a massage effect. Think of it as a social spa experience, but in your backyard. You can find them at resorts, gyms, or even private homes.
