A plunge pool is a small, deep swimming pool designed for relaxation and cooling off rather than swimming laps. Typically, these pools are built to be compact, making them ideal for smaller backyards or urban spaces. They often feature a depth that allows for a refreshing dip, providing a quick escape from heat. Plunge pools can be constructed using various materials, including concrete, fiberglass, or vinyl. Many homeowners choose to enhance their plunge pools with additional features like waterfalls, lighting, or surrounding landscaping to create a tranquil outdoor oasis.
