Knowing how much water your bathtub holds is important. Perhaps you are in the market for a new bathtub, planning out its location in the home where you will need to know how much it weighs to ensure the floor will hold the weight.
Once you know how much water it will hold, you can determine the weight.
Not all bathtubs are the same in regards to how much water they will hold. Some are larger than others and they can be different styles and shapes.
On average, a standard-size bathtub will hold 80 gallons or 302.83 liters of water.
Smaller bathtubs will hold 40 gallons (151.46 liters) and large ones will hold 100 gallons (378.541 liters).
1 gallon of water = 3.78541 liters.
