Rough-In Box | ChromaSteam

Mr. Steam ChromaSteam, Rough-In Box Mr Steam provides a secure foundation for installing ChromaSteam lighting, protecting wiring and terminations while simplifying placement behind finished tile, stone, or glass.

Lightweight at 1 lb, Model 104116 is easy to position in tight chases or overhead runs and supports tidy routing for future service. By standardizing the mount during rough-in, you enable even light distribution, cleaner sightlines, and a polished final presentation once trims are installed. Choose this dedicated box to streamline installation, safeguard components, and ensure your ChromaSteam system performs to specification from day one.
