1200 × 1800 mm Granite Slab — FAQ
- Is 1200 × 1800 mm granite slabs suitable for a small Guwahati bathroom?
- For bathrooms under 30 sqft, a smaller 300×300 or 300×600 anti-skid granite slabs is usually a better choice — less cutting waste, easier slope-to-drain, fewer site rejections. 1200 × 1800 mm works in larger bathrooms (40+ sqft) or where a single-piece wall feature is the design intent.
- How much 1200 × 1800 mm granite 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 1200 × 1800 mm granite slabs need rectified edges?
- For modern interiors with tight 2–3mm grout lines, yes — rectified-edge 1200 × 1800 mm granite 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 1200 × 1800 mm granite 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 1200 × 1800 mm granite 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 1200 × 1800 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 1200 × 1800 mm ship at 6–7mm, lower PEI, often with deeper glazing for visual richness. They are not interchangeable for structural reasons.
