What is the maximum height for the tile line on dark colored surfaces in a commercial pool?

The maximum height for the tile line on dark-colored surfaces in a commercial pool is set at 2 inches minimum. This specification is crucial for maintaining proper visibility and safety in the pool environment. The tile line serves as an important visual marker for swimmers and is particularly vital in areas where the pool surface may absorb more heat and cause discomfort.

The rationale behind this standard relates to the operational aspects of visibility. On darker surfaces, a higher tile line helps in creating a contrast that allows swimmers to easily discern the water's edge. A 2-inch minimum ensures that there is adequate differentiation between the pool's surface and the surrounding area, which contributes to both aesthetics and safety.

In commercial pools, where the volume of users is typically high, adhering to such standards is essential. It aids in preventing accidents by providing a clear visual cue, particularly in situations where lighting may be suboptimal. This requirement also reflects industry best practices, ensuring that pools remain both functional and safe environments for recreational activities.
