Questions about this item

What does the ASTM B117 and ASTM B368 rating mean for the black onyx finish?

These standards confirm the finish resists salt-spray corrosion and meets coating-thickness requirements, so the black onyx surface keeps its appearance under daily bathroom humidity.

How does the pressure-balanced cartridge work with my existing plumbing?

The ceramic cartridge automatically adjusts hot and cold flow to maintain a steady temperature when supply pressure changes, and it fits standard single-hole rough-ins with the included deck plate.

What mounting hardware is needed to install this tub and shower set?

The unit is designed for single-hole mono-block installation; the supplied deck plate covers the opening and the screwdriver stops let you service the valve without shutting off the main water.
