Thinking about it in these terms an 18 round above ground pool offers the same swimming area as a 12 x 24 oval above ground pool but for the same model often times up to 1 000 less.
Oval pool vs round pool.
The 24 round is generally only a few hundred dollars more than the 18 round but it s twice as big.
The 15 x30 oval is 1500 more than the 24 round and it has essentially the same amount of space and water.
The advantages of a round pool over an oval are just to significant.
The only reason an oval pool costs more than a round one is because of the oval s buttress structure.
They are 48 52 and 54 walls with the 54 above ground pool being the tallest and newest design of the three.
The braces add an additional five to six feet to the total width of the pool so an oval above ground pool takes up almost as much space as a round pool.
For example a 12 by 18 foot above ground.
A 24 round and a 15 x30 oval both hold around 15 000.
Round pools provide more swimming area at a lower price meaning you re getting the best price per gallon.
These straight sides need a structure to keep the wall from pushing out when the pool gets filled with water.
This support system will either be a buttress or buttress free system depending on your pool model.
The only time we see the oval as an advantage over round is when the customer s yard is longer than wide or when only an oval shaped pool could fit due to property line set backs garages septic systems and home layout.
That structure is called a buttress system and it has to be heavy duty and built well.
All above ground pool models are available in both round and oval shapes.
An 18 round pool holds around 8 000 gallons.
