Some Frequently Asked Questions About Large Marble Tiles

What counts as a large format marble tile, and how are they made?

Any marble tile where both length and width exceed 600mm. Common sizes include 600x600mm, 800x800mm, 600x1200mm, and 1200x1200mm. Unlike standard tiles produced on automated tile lines, large format marble tiles are cut individually on a bridge saw from full slabs — the same slabs used for worktops and feature walls. This means each tile retains the natural veining, crystal structure, and colour variation of the original stone. The cutting, handling, and packing all require significantly more care and labour than standard tiles, because a single misaligned cut or careless movement can damage an entire slab's worth of material.

Why are large marble tiles more expensive than standard sizes?

Three reasons, all related to the production process. First, bridge saw cutting is slower and more labour-intensive than automated tile production — each cut is set up individually by a skilled operator. Second, large format tiles demand end-to-end careful handling: from slab selection through cutting, edge finishing, quality checking, and packing, every stage requires extra manpower and slower movement to avoid chipping or cracking. Third, yield rates are lower — more material is lost to offcuts and any flaw that would be invisible in a 300x300mm tile can render a 1200x600mm piece unusable. The result is a product closer in character to a slab installation than a standard tiled floor.

Can I have large format tiles cut from any slab in your collection?

Yes. You are not limited to the stones shown in this section. If you see a slab anywhere on our site — Calacatta, Carrara, Statuario, an exotic quartzite, an onyx — we can cut it into large format tiles to your specification. Simply send us a quote request naming the stone and the tile dimensions you need. We cut to order on our bridge saws, so there is no restriction on which material can become a large tile. The minimum order is 18m², which typically covers a standard kitchen floor or a bathroom floor-and-wall combination.

Can large marble tiles be used on underfloor heating?

Yes — and marble is one of the best natural materials for it. Calcite has a thermal conductivity of roughly 2.5–3 W/m·K, significantly higher than ceramic or porcelain. This means marble transfers heat from the underfloor system to the room surface more efficiently and responds faster to temperature changes. The key requirement is a slow, controlled commissioning process: the heating system should be brought up gradually over 7–14 days after installation to allow the adhesive to cure fully before thermal cycling begins. Large format tiles cover more area per piece, meaning fewer grout lines interrupting the heat transfer — an additional efficiency advantage.

How do grout lines affect the appearance of large marble tiles?

Dramatically. A 600x600mm tile with 3mm grout joints creates a visible grid that interrupts the stone's natural flow. Reducing to 1.5–2mm joints with colour-matched epoxy grout minimises the visual interruption and creates something much closer to a full slab effect. Rectified tiles (machine-cut to exact dimensions after sawing) allow tighter joints. For the most seamless look, 1200x600mm or 1200x1200mm formats mean fewer joints per square metre, and the veining reads as a continuous surface. The combination of large format and tight grout lines is the most cost-effective way to achieve the look of a slab floor without slab-scale installation complexity.
