Many times a spa needs to be visually and aurally quiet so that it does not disturb what has been done with the pool. This is usually accomplished by keeping the spa flush with the pool and making it part of the overall configuration of the watershape.
The more playful, organic, and natural the pool is, the more freedom one has with the spa. This type of pool design allows for flexibility with the spa, allowing it to be large and full of falling water. However, the spa must still be in scale to the pool. All too often a spa becomes too large (physically/visually or raised too high) for the pool and overpowers it. There is something beautiful about water only dropping several inches and gliding down to the lower pool. Think of a brook, where the stream water glides over the submerged boulders … not loud, but hypnotic.
