Calacatta Octagon Marble Tiles 406x406mm for Floors & Walls

A masterpiece of rustic elegance, these genuine Calacatta marble tiles combine the iconic bright white background and bold grey veining with a soft, tumbled finish. The classic 406x406mm octagon shape creates a sophisticated, geometric pattern perfect for crafting floors and walls with enduring character and enhanced slip resistance.

Experience the Soul of Italian Design

Step into a world of timeless luxury with Intmarble's Calacatta Tumbled Octagon Marble Tiles. Sourced directly from the prestigious quarries of Italy, this tile embodies the spirit of classic design. Calacatta marble is celebrated globally for its luminous, milky-white field, which serves as a pristine canvas for the dramatic and graceful grey veins that sweep across each piece.

What sets this collection apart is its exquisite tumbled finish. Through a gentle process, the tiles are softened to create a velvety, matte texture and subtly rounded edges. This gives the stone an authentic, lived-in character reminiscent of historic European villas, while also making it wonderfully tactile and less slippery underfoot—a perfect blend of beauty and practicality.

The Enduring Appeal of the Octagon & Dot Pattern

The octagon shape is a design classic, synonymous with elegance and bespoke flooring. These 406x406mm tiles are specifically cut to be installed with smaller "dot" tiles (sold separately), creating the iconic octagon and dot pattern. This geometric interplay adds visual depth and a custom-tailored feel to any space.

Create your signature look:

• Classic Contrast: Pair with Nero Marquina black marble dots for a bold, timeless statement.
• Subtle Sophistication: Use Bardiglio Grey marble dots for a softer, more contemporary aesthetic.

Versatile Applications for Modern & Classic Interiors

The robust 12mm thickness and durable, non-slip tumbled surface make these tiles an exceptionally versatile choice for both residential and commercial projects.

• Luxury Bathroom Floors: The enhanced grip of the tumbled finish provides peace of mind in wet environments without sacrificing style.
• Statement Kitchen Floors: Create a stunning foundation in the heart of your home that is both beautiful and forgiving.

Care and Maintenance for Lasting Beauty

To protect your investment and ensure your marble stays beautiful for decades, we recommend the following:

1. Seal After Grouting: Tumbled marble is porous. Apply a high-quality penetrating stone sealer before and after grouting to protect against stains and moisture.
2. Use pH-Neutral Cleaners: Clean spills promptly and use only cleaners specifically formulated for natural stone. Avoid acidic or abrasive products.
3. Professional Installation: For best results, we advise hiring a tiler experienced in fitting natural stone. Always dry-lay the tiles first to create a balanced and beautiful pattern.

🔄 Tab 2: Returns & Refunds Policy

Because marble is heavy and fragile, we have clear rules for cancellations and returns.

1. The Natural Stone Rule (Please Read)
Marble is a 100% natural product. Every single tile has unique colors, shades, and veining. These variations are not defects—they are the natural beauty of the stone. If you decide to return your tiles because you do not like the natural veining, it counts as a standard return, and you must pay for the return shipping.

2. How Long You Have to Decide

• Everyday Shoppers (B2C): You have a legal right to change your mind within 14 days of delivery. If you live in the EU, you can do this instantly by logging into your account profile.

• We cannot accept returns for custom-cut stone, clearance items, or opened boxes.

intmarble.com Guide to Installing Natural Stone & Marble Tiles

Achieve a perfect, beautiful finish with our expert technical guide. Installing genuine natural stone requires careful planning. This guide helps homeowners and professional installers follow British Standards (BS 5385) for a flawless result.

✅ Important Pre-Installation Checklist

• Check for Transit Damage: You must inspect your delivery completely. Any shipping breakages must be reported to cs@intmarble.com with photos within 24 hours of delivery.
• The "Dry Run" Rule (Crucial): Before using any glue, unpack tiles from 3 to 4 different crates and lay them out loose on the floor. This lets you blend the natural colors and veining beautifully. Do not skip this step.
• Installation Means Acceptance: Always inspect your tiles during the dry run. Once a tile is glued down or sealed, it is officially accepted. We cannot accept returns, issue refunds, or handle claims for variations or defects after the stone has been installed.

🔧 Essential Materials & Tools

For the best results, we recommend using these professional-grade materials:

• Adhesive: Always use a high-performance, white flexible adhesive (Class S1 or S2). Using grey adhesive can bleed through and permanently stain light-colored marble from behind.
• Grout: Use a high-flexibility stone grout. We recommend a 2mm to 3mm grout joint.
• Sealer: Natural marble must be protected with a high-quality impregnating sealer before and after grouting, alongside pH-neutral stone cleaners.
• Tools: A wet-diamond bridge saw is required to cut marble cleanly without chipping.

📋 General Installation Rules

• Mix Your Boxes: Never tile out of a single box. Mix tiles from multiple crates as you go to ensure a balanced, natural distribution of veining across the room.
• Follow TTA Guidelines: Adhere strictly to The Tile Association (TTA) UK standards.
• Safety First: Always wear protective gloves, safety eyewear, and a dust mask when cutting stone.

🏠 Where Can This Stone Be Used?

• Bathroom Walls & Floors: Yes (Satin or Polished finishes).
• Kitchen Floors & Splashbacks: Yes (Sealing is mandatory to prevent food stains).
• Showers & Wet Rooms: Yes (Always verify the slip rating fits your project).
• Underfloor Heating: Yes (Marble holds and distributes heat beautifully).
• Outdoor Patios & Gardens: No. Natural polished marble is prone to frost damage and slipperiness outdoors and is not advised.

🚨 Liability Disclaimer & Variation Note

Natural stone is a unique masterpiece created by the earth; every single tile is different. Expect natural variations in veining, color shading, and crystal markings. This guide is for informational purposes only. intmarble.com accepts no liability for installation issues, installation mistakes, or stone damage caused by installers. For specific project requirements, always consult a certified professional tiler.

📋 The intmarble.com "Dry-Run" Rule

To get the most beautiful layout in your room, you must follow the Batch Calibration process. Before any glue or adhesive is applied, we require all customers and tilers to follow these steps:

1. Unpack Everything together: Open all your delivery crates or boxes at the same time.
2. Do a Dry-Lay: Arrange the tiles loose on a clean floor. Mix tiles from different boxes together.
3. Balance the Look: Move the tiles around until the colors and veining patterns flow naturally and beautifully across the room.

🚨 Legal Disclaimer & Quality Standards

It is important to understand that natural variations, shading differences, or mineral markings are not flaws or defects—they are the authentic signature of genuine stone.

• Installation Means Acceptance: In line with UK and European stone industry standards, installing the tiles means you fully accept them as they are.
• Our Claims Policy: Once the stone is fixed to the floor or wall with adhesive, we cannot accept returns, issue refunds, or handle any claims regarding color, shading, or veining.
• Delivery Damages: If any tiles are physically broken or cracked during shipping, this must be reported with photos to cs@intmarble.com within 24 hours of delivery, before installation begins.
• Change of Mind: If you decide to return your uninstalled tiles within your legal 14-day window because you do not like the natural variation, you are responsible for organizing and paying for the heavy pallet return shipping back to our Kilkeel yard.
