300 × 300 mm Marble Slab — FAQ

How much 300 × 300 mm marble slabs should I order for a 100 sqft room?

Order 105–110 sqft for 100 sqft of net coverage — the 5–10% buffer covers cutting waste, breakage and future repair stock. Our showroom team will run the BOQ math on your room dimensions before invoicing.

Does 300 × 300 mm marble slabs need rectified edges?

For modern interiors with tight 2–3mm grout lines, yes — rectified-edge 300 × 300 mm marble slabs is the standard. Non-rectified ships with looser edge tolerance and works fine for traditional 5mm grout. We confirm rectification status against every SKU before order.

How heavy is one box of 300 × 300 mm marble slabs?

A standard 4-piece carton of 600×600 8mm vitrified weighs about 28–32 kg. The 800×800 spec at 10mm runs 38–42 kg per carton. Larger sizes use single-tile cartons. Our delivery teams pre-stack on a pallet for site-friendly off-loading.

Can 300 × 300 mm marble slabs be installed over an existing floor?

Technically yes, with the right thinset adhesive and an inspection of the underlying slab — but doors and threshold heights need to be checked first. For pre-existing vitrified floors, removal is usually the cleaner option. We connect customers with installers who do this assessment on-site.

What is the difference between 300 × 300 mm floor and wall tile variants?

Floor tiles at this size ship thicker (8mm+), with higher PEI hardness (PEI-3 to PEI-4) and slip-rated surfaces. Wall variants of 300 × 300 mm ship at 6–7mm, lower PEI, often with deeper glazing for visual richness. They are not interchangeable for structural reasons.

Are imported 300 × 300 mm marble slabs options available?

Yes — we indent 300 × 300 mm marble slabs from Marazzi, Porcelanosa and Imola on request. Indian alternatives from Kajaria-Eternity and Simpolo Mavrick cover 80% of the imported aesthetic at one-third the price for typical residential builds in Guwahati.
