The granite kitchen platform is the hardest-working surface in an Indian home. It takes the weight of a pressure cooker, the heat of a tawa, the knock of a steel vessel and the daily spill of oil, haldi, tamarind and lemon. Granite is the most common choice for this job because it handles all of it, but the slab is only half the story. Thickness, edge detail, joint position and the way the sink and hob cut-outs are made decide whether your platform stays perfect or develops a crack within a year.
Here is how we plan and fix a granite kitchen platform on site, with the details we discuss with every homeowner and architect.
Choosing the granite for a kitchen platform
Dense, dark granites are the traditional choice for kitchens. Black Pearl, Telephone Black and Z Black hide stains, take heat well and keep a deep shine. Lighter granites such as S White or P White give a brighter kitchen, but they need sealing and more prompt wiping, as turmeric and oil can leave marks in more porous slabs.
Whatever you choose, select a slab long enough to cover the main run of the platform in one piece if possible. Fewer joints mean fewer places for dirt and water to collect.
What thickness should a granite platform be?
Most kitchen granite in India is supplied in slabs of roughly 16 to 20 mm. That thickness is strong enough for a platform that is properly supported along its length. A thicker look is achieved not by buying very thick slabs but by doubling the front edge.
Doubled front edge
A strip of the same granite is fixed under the front of the platform, giving a visible edge of roughly double the slab thickness. The two pieces are bonded with epoxy, clamped, then the edge is shaped and polished so it reads as one solid piece. This is the most common detail on quality platforms.
Support underneath
In most Indian kitchens, the platform rests on an RCC or stone shelf, or on brick and stone supports below. The top must sit on a full, level bed. Gaps under the slab, especially near the hob, are a common reason for cracks later.
Edge profiles for the front of the platform
The front edge is what you touch every day, so its profile matters for comfort and safety.
- Rounded or eased edge. Simple, clean, and gentle on hips and hands.
- Half bullnose. A smooth curve on the top edge, popular in modern kitchens.
- Full bullnose. A fully rounded edge; looks soft and traditional.
- Double-height moulding. Doubled edge with a shaped profile, often with a small step or groove.
Sharp, square edges look crisp in drawings but chip easily when a heavy vessel knocks them. We usually recommend at least a slight rounding even on a modern square look.
Sink cut-outs done properly
The sink area is where water, weight and stress all come together. A careless cut-out here is the most common failure point on a kitchen platform.
- Get the sink first. Cut-outs are made to the actual sink, not to a catalogue size.
- Round the inside corners. A sharp square corner in a cut-out is a natural crack starter. We drill or cut a small radius at each corner.
- Polish the visible edges. For an under-mount sink, the cut edge is fully visible and must be polished smooth.
- Slope for drainage. Grooves cut beside the sink help water run back into the bowl instead of standing on the platform.
- Seal the joint. The sink rim is sealed with a suitable sealant so water does not seep under the granite.
Hob cut-outs and heat
A built-in hob needs a precise cut-out in the platform. The same rule of rounded inside corners applies, and the narrow strips of granite left at the front and back of the hob must not be too thin. A thin strip is fragile and may crack from heat cycles and the weight of vessels.
We also avoid placing a joint near the hob. Constant heating and cooling works on epoxy joints and can open them up over time. If the platform must have a joint, we place it away from the hob and the sink, ideally at a corner.
Corners, joints and backsplash
L-shaped and U-shaped kitchens need corner joints. A miter joint or a neatly butted joint, filled with colour-matched epoxy, becomes almost invisible on a dark granite. The joint must be supported from below so the two slabs cannot move independently.
The backsplash strip, usually 75 to 100 mm high or a full wall up to the cabinets, is fixed after the top. The joint between platform and backsplash is filled and sealed so water and food cannot collect there. Some clients prefer a full granite backsplash behind the hob, which is very easy to keep clean.
Plumbing and electrical coordination
Before the platform goes in, plumbing points for the sink, water purifier and dishwasher, and electrical points for the chimney, hob and appliances must be in their final positions. Cutting holes in granite after fixing is possible but riskier. A quick site meeting with the plumber, electrician and carpenter saves a lot of trouble.
Kitchen platform checklist
- Sink and hob purchased and available at site for cut-out measurement.
- Platform height agreed, usually based on the main cook's comfort.
- Support shelf or base levelled and strong along the full length.
- Joint positions decided away from sink and hob.
- Front edge profile chosen.
- Plumbing and electrical points final.
