Question

A king size waterbed how much water does it take to full it?

Answer 1

I'd think about 150 gallons

Answer 2

I agree in part with all answers so far, and the math in how much is relatively easy, as suggested. You can probably assume the mattress as a rectangle, containing perhaps as much as 42 "CUBES" of water.

   Without doing the math myself, the conversions are easy to find online.

   I suspect more than 250 gallons, and I measure water at closer to 8.5 pounds per gallon, which as others state should be a consideration for you, depending on placement.

  Even at 250 gallons @ 2125 lbs. Plus the weight of the bed itself, you're over a TON sitting on a space approximately 6 ft by 7 ft. I think I'd want to know what the floor can hold, especially if not on a slab.

Just my two "sense"

Answer 3

i do not remember how many gallons , it did weigh 1200 pounds when full. make sure your floor can handle the weight  to , i had a mishap twice with that .

Answer 4

About 230-250 gallons.

Answer 5

Water weighs 8.3lbs/gallon 64lbs per cubic foot. Should be an easy math problem
