The capacity of a standard tub is directly related to its size. According to the Alliance for Water Efficiency, a standard whirlpool tub without contains between 25 and 45 gallons (110 to 200 L) of water approximately. The average rectangular bathtub is about 30 inches (75 cm) wide and 5 feet (1.5 m) long, according Plumbing-Basics. They come in many different forms, however, such as circular or rounded models, and this may affect the ability.
Water consumption varies significantly depending on how high you fill the rectangular bathtub. If you fill it halfway, you’re using about 20 gallons (90 L). If you fill up or above the overflow valve, you are using 40 to 50 gallons (180-220 L). Compare this with a shower, using a 20 gallon (90 L) over five minutes.
