This facility was built to attract people of all ages, blend in with surrounding buildings, and provide a sheltered aquatics environment during the Seattle area’s many rainy days — all while embracing the natural beauty so cherished in the state.

A partnership between the City of Sammamish and the YMCA of Greater Seattle resulted in this 6,000-square-foot indoor facility with plenty of natural light and outdoor views. Features include a leisure pool with zero-depth entry, current channel, geysers, spray features and a water table; indoor/outdoor flume slide; a six-lane, 25-yard lap pool; and a spa.

A glass wall separates the lap and leisure pools, promoting interconnectedness while reducing distraction for serious sport swimmers. The current channel can support leisurely floating or resistance walking.

In addition to boasting the state’s first fully LED-lit pool, the design incorporates a heat-recovery system to save energy. A rainwater collection system under the parking area takes what has flowed through vegetation to be used for flushing toilets.

The aesthetic was formulated for a loose representation of nature. Curved edges on the pool contour around each other, similar to how a river bends. Muted earth tones subtly evoke sand, rock and water, while bolder accents of yellow, red and blue mark areas meant for younger swimmers.

The deck is covered with small tiles in grays, tans and off-whites to recreate a beach walk. Soft gray tiles cover the exposed portion of the pool walls to evoke the natural rock formations found near lakes and rivers.
