About White Onyx Honed Onyx Slab
White Onyx Honed Onyx Slab Random brings the luminous character of white onyx into a clean, modern slab format. Crafted from onyx with a honed finish, this rectangular slab presents a softly refined surface rather than a high-polish appearance. Its white color and White Onyx color group create a restrained material foundation for interiors centered on light, texture, and natural stone.
Supplied in a random size format with a 3/4-inch thickness, this slab is designed for applications that benefit from the visual continuity of large-format stone. The straight-cut edge provides a crisp, architectural outline that works well with tailored detailing and contemporary compositions. Natural variation is part of the character of onyx, giving each slab its own visual expression.
White Onyx Honed Onyx Slab Random is listed for residential interior walls, commercial interior walls, shower walls, and residential countertops. It can be considered for bathroom, kitchen, and living room settings where a white onyx surface supports the overall material palette. The honed finish offers a quieter visual effect that complements modern design schemes.
Whether used as a feature wall surface, a shower wall treatment, or a residential countertop material, this onyx slab provides a substantial stone presence. Its rectangular shape, honed finish, and straight-cut edge allow the natural qualities of white onyx to remain the focus within a composed interior design.
At Marble Systems, we pride ourselves on offering the highest-quality natural stone slabs, including marble, limestone, quartzite, and travertine. To ensure the beauty and durability of your stone investment, proper installation and ongoing maintenance are essential. Please review the following guidelines before handling or installing any Marble Systems slabs.
1. Slab Inspection & Fabrication
- All slabs must be inspected upon delivery for color variation, veining, structural soundness, and finish quality.
- Any cracks, fissures, or natural features should be reviewed with your fabricator prior to cutting.
- The final layout, cutting, and installation of the countertop or stone application must be determined by a licensed and experienced stone fabricator.
- Bookmatching and vein alignment must be planned prior to fabrication.
2. Installation Guidelines
- All substrates must be level, structurally sound, and properly reinforced for the weight of natural stone.
- Use appropriate backer boards, supports, and adhesive systems recommended for natural stone slabs.
- Expansion joints should be incorporated where applicable.
- Ensure all cutouts (sinks, cooktops, etc.) are properly supported.
- Avoid dragging heavy equipment or materials across the slab surface during install.
3. Sealing & Surface Protection
- All natural stone slabs must be sealed prior to or immediately after installation with a high-quality penetrating sealer appropriate for the stone type.
- Resealing should be performed every 6–12 months, depending on usage and exposure to moisture or staining agents.
- Acidic substances (e.g., citrus juice, vinegar) can etch marble and limestone. Clean spills promptly.
4. Sealing & Surface Protection
- Use pH-neutral, stone-safe cleaners only.
- Avoid abrasive scrubbers or harsh chemicals.
- Use coasters, trivets, and cutting boards to preserve the surface.
- Wipe down countertops daily with a soft cloth or sponge.
5. Disclaimer
- Natural stone is a product of nature and may feature inherent color and texture variations.
- Marble Systems is not responsible for wear and tear, etching, or staining on finished stone slabs once installed.
- All final fabrication, handling, and installation decisions must be made by a qualified stone professional or licensed fabricator.
