Curvilinear Spa

摘要

A curvilinear spa shell includes a top edge defining four rounded concave corners and four convex side walls in a "clover leaf" like arrangement. Each rounded corner has a radius that exceeds twelve inches. The top edge is substantially symmetrical about an axes that extend through the center of opposing side walls as well as through the center of opposing corners. The curvilinear spa shell can accommodate a water feature for generating a pleasing rushing water sound. The water feature includes a ridge in an interior area of the spa and having a top disposed near a water line of the spa. The water feature utilizes a water inlet adjacent to the ridge opposite a main body of water area in the interior area. The water inlet is placed lower than the top of the ridge. The water feature also includes a slope descending from the top of the ridge in the direction of the water inlet. The slope includes a patterned top surface configured to interact with water flowing over the ridge, down the slope and toward the water inlet to produce the pleasing rushing water sound.
