Thassos White Marble 5/8 x 5/8 Mosaic Tile – Polished or Honed (A1) brings a pristine, radiant canvas to any indoor space. Crafted from Greek Thassos marble, this mosaic pairs cool, pure white with the subtle depth that only natural stone delivers. Available in two exquisite finishes, you can tailor the mood from bright and reflective to soft and contemporary, all with the same timeless elegance.
Why this mosaic stands out:
- Two finishes for true design flexibility — choose polished for a high-gloss, light-maximizing surface or honed for a matte, slip-resistant feel that’s ideal for wet areas.
- Consistent white, with natural character — Thassos marble offers a clean, bright backdrop with gentle variation that adds depth without competing with your décor.
- Compact, easy-to-install mosaic — 5/8 in x 5/8 in square tesserae arranged on a mosaic format minimizes grout lines and simplifies layout for kitchens, baths, and feature walls.
- Versatile applications — ideal for kitchen backsplashes, shower walls, bathroom niches and floors (with proper sealing), fireplace surrounds, and accent walls that demand a luxe, airy feel.
- Grout and installation considerations — light-gray or matching white grout pairs beautifully with the marble’s cool tone; for wet areas, consider epoxy grout for enhanced stain resistance. Professional installation with a suitable stone adhesive and a penetrating sealer is recommended.
Best used in spaces where brightness and clarity are key. The polished option amplifies light, making small rooms feel more expansive, while the honed finish softens glare and provides a sophisticated, modern texture that hides fingerprint marks a bit better—perfect for countertops splashes, shower enclosures, or feature walls that deserve attention without glare.
Care and longevity tips to keep your Thassos mosaic looking its best: seal the tile and grout after installation and re-seal as recommended by your installer, clean with pH-neutral stone cleaners, and blot spills promptly to avoid staining. Avoid acidic or abrasive cleaners that can etch the marble’s surface. With proper sealing and maintenance, this A1-grade mosaic maintains its luminous appearance for years, making it an enduring choice for both contemporary and classic designs.
Ideal for homeowners, designers, and renovators seeking a monochrome, high-end aesthetic that pairs beautifully with metals, glass, and light woods. If you’re envisioning a clean, timeless backdrop that elevates any space—this Thassos white mosaic delivers that unmistakable, luxurious glow.
Installation Guidelines
The owner or owner’s representative is responsible for determining the acceptability of the product prior to installation. All Installations should be done by a professional tile installer.
1. Measuring: Measure coverage area, make sure to purchase at least 10% extra material than is required. This will account for any breakage or mis-cuts during installation, and ensure you have extra material should you have to replace any tile elements in the future.
2. Verifying Dye Lot Consistency: The owner or end user is responsible for determining the acceptability of the product. Due to the handmade, artistic nature of our product, variation in color, shade, tone, and size is normal.
- Upon delivery, open and inspect each box of tile.
- Verify dye lot consistency in the following manner. To establish color control samples, randomlyselect 5 pieces from your order from different boxes.
- To assure shade variations are acceptable check, the remaining sheets or field tile in your order againstthe control samples, prior to installation.
- If ordering additional materials. Sample shall be sent to help attempt to match previously orderedmaterial.
3. Setting Material: Because of the translucent nature of glass, the color of the bonding material will impact the ultimate look of the tile. We highly recommend the use of white polymer modified white thin-set.
Acceptable Thin-Sets (White Color):
- CUSTOM BUILDING PRODUCTS: Premium Glass Tile Thin-Set Mortar
- BOSTIK: Glass-MateTM GLASS TILE MORTAR
- BOSTIK: ReFlex Ultra-Premium Latex Modified Thin-Set Mortar

4. Cutting: Plan the placement of the tiles on your wall prior to installation. If you need to cut a mosaic sheet, cut from the back using a utility knife between tiles along the grout joints. Should you need to cut across tiles in a fashion that is not possible with a utility knife, use a wet saw with a diamond blade to cut through the tile.
5. Drilling: Using a drill bit designed for glass is recommended. When drilling the hole, keep the bit and hole lubricated to prevent chipping. Start by drilling from both ends of the tile, starting with the back and drilling half the depth of the tile. Then, turn the tile over and complete the hole is recommended. This will prevent the glass from chipping as the drill bit exits the tile.
6. Applying Setting Materials:
Apply setting material using the notched side of a V-notched trowel. Using the flat side of the trowels, smooth out all ridges to achieve a consistent, even 1/8” (3mm) coverage.
- Apply glass mosaic sheets, mesh -side down, firmly into freshly laid setting material. Mix and match from assorted sell units to achieve consistent variation. Using a rubber grout float gently press the tile into adhesive to ensure complete contact.
- Natural Stone should be sealed prior to grouting. A premium penetrating sealer is recommended for a natural look. Please refer to sealer manufacturer’s recommendations for application instructions.
7. Cleaning: Clean all excess grout immediately with a damp sponge. After 12 hours polish off any remaining haze with a dry cloth or towel. For tough stains, we require the use of PH Neutral cleaner to clean the tile and grout, such as Grout & Tile neutral cleaner.

Maintenance, Care & Cleaning (Marble and Natural Stone Products)
Cleaning marble surfaces requires gentle care as they are easily scratched and can be damaged by acidic substances.
1. **Regular Cleaning**: Dust the surface regularly with a soft, dry cloth. For a more thorough clean, use a damp cloth and a little mild soap. Make sure you thoroughly rinse the surface after to remove any soap residue and dry it with a soft towel to prevent water spots.
2. **Deep Cleaning**: You can buy a pH-neutral stone cleaner specifically designed for marble. Dilute the cleaner according to the instructions, then apply it to the marble. Use a soft, damp cloth or sponge to clean the surface. Rinite with clean water and wipe dry.
3. **Stain Removal**: If there's a stain, try to identify what caused it, as different types of stains require different treatments. In general, a poultice made from baking soda and water can help lift the stain. Apply the poultice to the stain, cover with plastic wrap, and leave it overnight. Clean off the poultice with water the next day and pat dry.
Remember not to use vinegar, lemon juice, or other cleaners containing acid on marble surfaces, as they can etch the marble surface. Also, avoid using abrasive cleaners or tools that might scratch the marble. It's always a good idea to test any cleaning method on a small, inconspicuous area first to ensure it doesn't damage the marble.
We strongly recommend customers to use a licensed tile contractor to do the tile installation and always use TCNA tile installation handbook as the installation guidance
