Round Pools
Water pressure distributes evenly — no extra bracing needed. Simpler, faster, and less expensive than oval at equivalent volume.
No A-frame buttresses — simpler installation
Lower price at equivalent water volume
Available in more sizes — 12' through 30
Works in square or irregular yards
Shorter swim lane than oval at same footprint
For Rectangular Yards
Oval Pools
Better for long, narrow yards. Requires A-frame buttresses that extend 2–3 feet beyond the pool wall on the long sides.
Fits rectangular yards more efficiently
Longer swim lane — better for exercise
More complex installation — buttress assembly required
Buttresses extend 2–3 feet beyond pool edge
Higher price than round at equivalent volume
