Kota Stone Sizes, Thickness & Finishes

Why size, thickness and finish matter together

With Kota stone, the same colour can perform very differently depending on how it is cut and finished. A 25 mm polished 2×2 ft tile is a very different product from a 30 mm rough random slab, even if both come from the same quarry bed. This guide explains each choice so you can match the stone to the area, the load it will carry and the look you want.

Standard tile sizes

Square sizes such as 16×16, 18×18, 20×20, 22×22 and 24×24 inches are common for rooms and corridors. Smaller squares suit small rooms and older homes and are easier to handle; larger squares give fewer joints and a more open look. 24×24 inches is often called 2×2 ft and is one of the most requested formats for homes and offices.

Rectangular formats such as 24×12, 24×18 inches and 4×2 ft work well for long corridors, verandahs and outdoor paths, and can be laid in staggered or herringbone patterns. Large 4×2 ft pieces need careful handling and a well-prepared base to avoid breakage.

Random slabs versus cut tiles

Random or uncut slabs come in irregular dimensions and are cut at site. They are usually cheaper per square foot and allow the installer to make large pieces fit large rooms, but wastage and labour are higher. Cut tiles arrive in exact sizes, are faster to lay and give neat, uniform joints. For big public areas, contractors often prefer cut sizes for speed; for budget projects with skilled local masons, random slabs can be economical.

Choosing thickness

Kota stone is commonly supplied from about 15 mm up to 40 mm, with custom thickness possible on request depending on availability. As a general guide:

• 15–20 mm: light residential floors on a solid, level base; wall cladding.
• 20–25 mm: standard home and office flooring.
• 25–30 mm: commercial floors, stairs, treads, outdoor paving and terraces.
• 30–40 mm: parking, driveways, industrial floors and areas with heavy loads.

Thickness and the base

Thickness alone does not make a floor strong; the base matters more. A thin slab on a well-compacted, level concrete base can outperform a thick slab on a weak or uneven base. For vehicle areas and industrial floors, the base, bedding mortar and joint design should be decided by your engineer. Calibrated stone, which has uniform thickness, makes levelling easier and is useful when stone is fixed with adhesive rather than a thick mortar bed.

Finish options in detail

Polished and mirror-polished finishes give a glossy surface that highlights colour and is easy to mop; they are best for dry interiors. Semi-polished and honed finishes have a softer sheen and slightly more grip. Matte finishes reduce glare. Natural and sawn finishes are the stone as split or cut, with good grip. Rough and hand-dressed finishes are coarser and suit outdoor and industrial use. Textured, leather and anti-skid finishes are mechanically treated surfaces designed to stay grippy when wet.

Remember that polished stone becomes slippery with water, oil or dust. For stairs, ramps, entrances, bathrooms, pool surrounds and terraces, use a textured or anti-skid finish, or add anti-skid grooves to step nosings.

Maintenance by finish

Polished surfaces lose shine over time in heavy-traffic areas and can be re-polished by a floor polishing contractor. Natural and rough surfaces hide wear well but can hold dirt, so periodic scrubbing helps. All finishes should be cleaned with neutral, non-acidic cleaners, because acids etch limestone. Sealing can help reduce staining in kitchens and dining areas.
