wall angles

As a veteran watershape engineer, Dave Peterson has reviewed plans for countless vanishing-edge projects. Along the way, he's developed a preference for a specific approach to angling the top of the edge wall, offering guidance here that applies in nearly every case.

Making Edges Vanish

There are two common options when it's time to design the wall for a vanishing-edge swimming pool: cut it in or cut it away. With a cut-in approach, the top of the wall is cut down into the pool so that the water surface extends to the outside edge of the wall - effectively submerging it even when the water is not flowing over the edge. By contrast, a cut-away wall is one where the top of the wall angles down and away from the pool so that the water surface terminates at the inside edge of the wall. This results in the
