What is the maximum distance that lath or reinforcement should extend in showers from the floor according to ANSI standards?

According to ANSI (American National Standards Institute) standards for tile installations, the correct guideline states that lath or reinforcement in shower areas should extend a maximum of 6 inches from the floor. This requirement ensures adequate support for the tile and helps prevent issues like cracking or moisture infiltration. The distance is specified to maintain sound structural integrity and proper drainage in wet areas, which is crucial in preventing water damage and ensuring longevity in tiled shower environments.

While the provided answer states 2 inches, this is not in alignment with the ANSI standards, which emphasize a 6-inch extension to adequately support the installed materials above the floor level.
