Six things go into a tiled floor:
- The tile
- The adhesive, or a cement-sand bed
- Grout
- Laying labour
- Skirting, material and labour
- The tiles you buy and never lay
A showroom prices the first one. Every comparison people make between flooring options is a comparison of that single line, which is why the floor always costs more than the quote said it would.
The worked example: one 10 x 10 room
100 sq ft of floor, 600 x 600 mm vitrified tile, four tiles to a box, showroom rate Rs 55 per sq ft. Here is what the tile calculator works out, and you can redo all of it on paper.
Look at the tile line. You needed 26, you allowed 8% for cutting and breakage so you need 29, and because shops do not sell loose tiles out of a box you buy 32. Those 32 tiles are 124 sq ft of tile for 100 sq ft of floor.
At Rs 55 a square foot, that is Rs 6,820 — which is Rs 68.20 per square foot of floor before anything else has been bought. The tile has gone up 24% and nobody has mixed any adhesive yet.
To be fair about it: 29 tiles is the genuine requirement, which is Rs 6,181 or Rs 61.81 per sq ft, and the 3 extra tiles are spares you should keep anyway. Finding a matching tile from the same batch in three years is close to impossible. But the money has left your account either way.
Now the rest of the bill
| Item | Quantity | Cost | Per sq ft of floor |
|---|---|---|---|
| Tile, 8 boxes | 124 sq ft of tile | Rs 6,820 | Rs 68.20 |
| Adhesive, 2 bags of 20 kg | 37.2 kg needed | Rs 960 | Rs 9.60 |
| Grout, 5 kg pack | 4.65 kg needed | Rs 300 | Rs 3.00 |
| Laying labour | 100 sq ft | Rs 3,200 | Rs 32.00 |
| Skirting, 4 tiles + 37 running ft | 11.3 m run | Rs 1,778 | Rs 17.78 |
| Laid cost | Rs 13,058 | Rs 130.58 |
A Rs 55 tile produced a Rs 131 floor. That multiple is at its worst in a small single room, because skirting is driven by perimeter and box rounding hurts most on small quantities. Scale it up to a whole house and it settles down.
The same tile across 1,000 sq ft
Rs 55 of tile, Rs 115 of floor. A little over twice the showroom rate, and that ratio holds reasonably well across most tile choices because four of the five cost heads barely move when you change tile.
Laid cost by material
Tile and slab rates move with city, lot and season, and labour moves with how fiddly the material is to lay. These are the bands to plan with, not quotes:
| Material | Material rate | Laying labour | Laid, per sq ft |
|---|---|---|---|
| Ceramic floor tile | Rs 30 – 55 | Rs 22 – 32 | Rs 85 – 130 |
| Vitrified, standard 600x600 | Rs 45 – 80 | Rs 25 – 35 | Rs 100 – 160 |
| Vitrified, double-charged | Rs 70 – 120 | Rs 28 – 40 | Rs 135 – 210 |
| Large format, 800x1600 and up | Rs 110 – 250 | Rs 45 – 80 | Rs 200 – 380 |
| Kota stone | Rs 35 – 70 | Rs 30 – 45 | Rs 90 – 150 |
| Granite slab, 18 – 20 mm | Rs 90 – 250 | Rs 45 – 75 | Rs 160 – 350 |
| Indian marble | Rs 90 – 300 | Rs 50 – 85 | Rs 180 – 420 |
| Laminate wood | Rs 70 – 160 | Rs 25 – 40 | Rs 110 – 220 |
| Vinyl or SPC plank | Rs 60 – 150 | Rs 20 – 35 | Rs 95 – 200 |
| IPS or tremix cement finish | — | — | Rs 45 – 90 |
Three things in that table are worth reading twice.
Granite and marble carry costs after laying. Both are laid on a cement-sand bed and then ground and polished in place, which is a separate trade and a separate bill. A granite quote that stops at "laid" is usually not including final polishing.
Large format is a labour decision, not a tile decision. An 800 x 1600 tile needs two or three people to lift, levelling clips, a dead-flat base, a wet cutter, and more adhesive per square metre than the calculator's standard 4 kg — budget 6 to 8 kg for these. Half the price jump is in getting it down flat.
Laminate and vinyl need a flat base you probably do not have. If the existing screed is out of level, a self-levelling compound adds Rs 35 to Rs 70 a square foot before a single plank goes down. Ask about the base before accepting the headline rate.
Adhesive or a cement-sand bed
Thin-bed adhesive is the modern method: 3 to 4 mm of it, 4 kg per square metre. The traditional method is a 30 to 40 mm cement-sand bed. People assume the old way is cheaper. At current rates it is not:
Adhesive is cheaper, thinner, and far more reliable under vitrified tile, which absorbs almost no water and does not bond well to a cement bed. The bed still has its place: granite, marble and Kota slabs vary in thickness, and the bed is what takes up that variation to give you a level floor. For those it is the correct method, not the cheap one.
Wastage: the percentage is the floor, not the ceiling
The calculator uses 8% as standard. Use 12% for diagonal laying, for rooms with a lot of corners and niches, or for large format where a bad cut writes off an expensive tile.
But as the 100 sq ft example showed, the box is often the real constraint. You needed 29 tiles and bought 32, which is effectively 23% over the bare requirement. On small areas — a bathroom, a utility, a landing — work out the boxes, not the percentage, because the rounding is the bigger number.
Two rules that cost nothing and save real money: buy the whole house in one lot, because shade varies between production batches and the difference shows badly across a continuous floor; and keep four or five tiles per design aside in the store room rather than counting them as waste.
Skirting is a perimeter cost, so small rooms pay more
Skirting is cut from full tiles. A 600 mm tile cut into 100 mm strips yields six pieces, so the 11.3 m run in a 10 x 10 room takes 19 pieces and therefore only 4 tiles. Material is cheap; the cutting and the careful laying are not. Laid, skirting runs about Rs 45 to Rs 70 per running foot.
Because it scales with perimeter and the floor scales with area, skirting costs around Rs 18 per sq ft of floor in a 100 sq ft room and about Rs 13 in a 200 sq ft one. It is not a line to delete — it protects the wall bottom from mopping — but it is a reason not to judge a flooring quote on a single small room.
What moves the laying rate
Tiling labour is quoted per sq ft and the spread between two quotes for the same tile is usually explained by one of these:
| Factor | Effect on the labour rate |
|---|---|
| Tile size | Bigger tiles are slower per piece but faster per sq ft, up to about 800 mm. Past that the rate climbs steeply. |
| Diagonal or pattern laying | Adds roughly 20% to 30%, plus the higher wastage figure |
| Wet areas | Bathroom and utility floors need a fall towards the drain. Slower, and worth paying for. |
| Wall tiling | Usually quoted Rs 5 to Rs 12 above the floor rate for the same tile |
| Floor height to work from | If the screed level is wrong, the tiler is correcting it with adhesive, and will price that in |
| Grout type | Epoxy grout is a different skill and a different rate. It also costs Rs 250 to Rs 450 a kg against Rs 50 to Rs 80 for cementitious. |
Epoxy grout is the one genuinely worth considering as an upgrade in a kitchen or bathroom — it does not stain, does not grow mould in the joint, and at 0.5 kg per sqm the extra cost on a 200 sq ft wet area is only a few thousand rupees. On dry bedroom floors it is money spent for nothing.
The word that causes the arguments
When a turnkey quotation says "flooring allowance Rs 90 per sq ft", that figure almost always means the tile, with laying folded into the overall per sq ft build rate. Read it as a laid rate and you will believe you have been allowed a Rs 90 floor when you have been allowed a Rs 90 tile, or the reverse — and the gap is around Rs 55 a square foot, which on 1,000 sq ft is Rs 55,000.
So ask one question and get the answer in writing: does the allowance cover the tile only, or tile plus adhesive plus labour plus skirting? Reading a contractor quotation covers how rate allowances work and why they settle most finishing disputes before they start.
Then price your own floor properly: area, tile size, boxes, adhesive, grout, skirting run. Once you have a laid number per square foot, comparing a Rs 50 tile against a Rs 95 one becomes a decision about a Rs 45 difference, and most people make a better choice at that point than they would have in a showroom.
