Questions about the onyx collection
Quick answers about the look, feel, and care of your new shower.
What does the onyx surface feel like?
The solid-surface panels are smooth and warm to the touch, not cold like tile or stone. The non-porous finish has a slight satin sheen that resists water spots and feels clean.
How is the color and pattern applied?
Color is integral to the full depth of the material, ensuring lasting consistency. Engineered aggregate patterns are cast throughout the entire sheet, so any chips or scratches remain virtually invisible — with no contrasting layer exposed beneath the surface.
Are the walls easy to keep clean?
Yes. The non-porous surface means soap scum and mildew have nothing to grip. A quick wipe with a mild cleaner and a microfiber cloth is all it takes to restore the original look.
Does it sound hollow when you tap it?
No. The solid construction has a dense, quiet feel. Water running on the panels sounds softer than on tile, and the walls don't echo like thinner surrounds.
Can you match the shower base and walls exactly?
Yes. The shower bases are cast from the same material and color formula as the wall panels. The entire enclosure—floor, walls, corner shelves, and soap dish—reads as one continuous surface.
Will the color fade over time near a window?
No. The Onyx material is UV-stable and resists yellowing. The color stays consistent even in bathrooms with natural light exposure throughout the day.
