Start with the rectangle pool shape line
A rectangle pool uses straight sides and square corners. The planning question is whether one strong axis organizes swimming, architecture, and other use zones.
Pool shape planning
Planning a Rectangle Pool Shape
Compare pool geometry with the way you want to swim, gather, move, and use the surrounding yard.
Read the shape against the site and intended use
Study home alignment, swim direction, recreation, gathering, approach, access, and surrounding-space priorities.
Compare adjacent directions on the same questions
Rectangle keeps one axis, Roman changes the ends, Grecian clips corners, and L-shaped adds a second leg.
Turn the preference into a feasibility brief
Test the measured site, access, intended activities, entries, seating, surrounding space, systems, requested features, and required approvals together.
