The depth of the pool is a crucial consideration based on its intended use. For recreational purposes, a depth of 91 to 152 centimeters (3 to 5 feet) is recommended, while 91 to 183 centimeters (3 to 6 feet) is ideal for active swimming and water sports. A depth of 76 to 107 centimeters (2.5 to 3.5 feet) is suitable for children's safety.
