How much weight can the average bathtub hold?
Just so, is there a weight limit on bathtubs?
The floor framing for bathtubs requires special attention. A standard bathtub can hold between 40 and 60 gallons of water. A gallon of water weighs approximately 8.35 pounds, so a standard tub filled with water can weigh between 335 and 500 pounds.
Similarly, it is asked, what is the capacity of a standard bathtub?
The capacity of a standard tub is directly related to its size. According to Alliance For Water Efficiency, a standard non-jetted bathtub holds between 25 and 45 gallons of water approximately. The average rectangular bathtub is about 30 inches wide and 5 feet long, according to Plumbing-Basics.
If the floor was built using the general 16-inch spacing, you can expect a bathroom floor to safely hold 40 psf. So, a 5-by-10 foot bathroom floor generally supports up to 2,000 pounds. This provides sufficient support for most cast iron bathtubs, which run under 500 pounds, even when full.
