There likely is such a thing but, they are not common. Typical sizes start at 12' round.
A 22-foot round pool that is 4 feet deep holds about 43,238.5 liters of water.
If the circumference of the round pool is 29 feet, then the volume of the pool (area times depth) is about 267.7 cubic feet.
It would be about 1.8535 feet deep.
About 17,950 gallons.
Three feet of water in a 12-foot round pool is about 2,550 gallons.

This pool can hold up to 1,689.7 gallons of water.
Twelve feet of water in a 10-foot round pool is approximately 7,080 gallons.
Here is a start. 1000 gal = 133.680 cubic feet/ for volume of a round pool...... remember Pi, 3.14?
That would depend what shape and how deep the pool is.If it is a round pool, 18 feet across and 4 feet deep, you would have 1000 cubic feet (pi R squared D), which is 28,300 liters.
6,200 gallons.
3,398.4 gallons.
