How to Read a Tile Installation Quote in Guwahati
By Team Rishi Marble and Granites · 7 August 2026
Customers walk into our showrooms with one of two questions: how much does the tile cost, and how much does it cost to lay it. The first is easy — you point at the tile and we quote it. The second is messy, and every contractor will give you a different number for what looks like the same job.
This article does not tell you what installation should cost. Labour rates move with the season, the tile format, the floor's condition and how busy the local trade is, and any published figure would be out of date and misleading the week after it went up. What it does instead is more useful: it tells you how to take a quote apart, so you can compare two of them honestly and see what has been left out of the cheaper one.
What goes into the total cost
A tile installation has six cost lines, not one. Pulling them apart is the only way to compare contractor quotes fairly.
- Material — the tile itself. Per-sqft price × area, plus a 5–10% wastage buffer.
- Adhesive. Either thinset cement mortar or polymer-modified adhesive.
- Grout. Sand-cement or epoxy.
- Labour. Per-sqft installation charge, varying by tile size and complexity.
- Site preparation. Floor levelling, screeding, and demolition of the old surface if there is one.
- Transport and incidentals. Truck unload, lift to upper floors, breakage allowance.
Skip any of these in a quote and you will see them reappear later as "extra" line items. Insist on a written bill of quantities that breaks out all six.
What drives the labour number up and down
You cannot sanity-check a rate without knowing what moves it. In rough order of impact:
- Tile format. Larger formats need a flatter substrate, more careful setting and often two people to place a single tile. A 1200×2400 slab is a different job from a 300×300.
- Slope-to-drain. A bathroom floor has to fall towards the drain from every direction. It is materially more work than a flat floor, and a bathroom quoted at flat-floor rates is the clearest single sign that a quote has not been thought through.
- Cuts. Toilets, basins, shower glass, pipe penetrations and mitred skirting all add labour and waste. A room with a lot of fittings is not the same as an open bedroom of the same area.
- Demolition. Taking up an old floor is a separate line with its own debris-disposal cost attached.
- Season. The dry build window is when everybody is building, and rates follow demand. The monsoon slows external work and softens rates.
Hidden costs people forget
- Slope-to-drain in bathrooms. Always more labour than a flat floor.
- Cut tiles around fittings. The wastage buffer that works for an open room is a floor, not a ceiling, in a bathroom.
- Skirting detail. Mitred-edge skirting is roughly double the labour of straight skirting.
- Existing floor demolition. Both the removal itself and the truck haul to a municipal disposal site.
- Adhesive quality. Cement-only mortar is a false economy under sustained monsoon humidity. Polymer-modified adhesive is the right call in Assam, and it is not the line to save on.
- Site supervision. Larger contractors fold it in; smaller ones charge it separately, per day. Ask which.
When to use the contractor's tile and when to buy your own
Some contractors offer a combined "tile and lay" quote at an attractive headline number. The trade-off:
Approach | Pros | Cons |
|---|---|---|
Contractor sources the tile | A single point of accountability, simpler billing | You do not see the actual brand and series until delivery, and the warranty trail is murky |
You source the tile, contractor lays it | Brand transparency, the manufacturer warranty stays in your name | Two billing chains and a little coordination overhead |
We have an obvious interest in the second option, so weigh this accordingly — but the warranty argument stands on its own. A manufacturer warranty is honoured against the invoice that names the buyer. If the tile is bought by your contractor, the warranty is his.
How to read a contractor quote
A reviewable quote names a quantity, a unit and a rate on every line:
Floor tile laying 950 sqft × rate = subtotal
Bathroom anti-skid 85 sqft × rate = subtotal
Wall tile 390 sqft × rate = subtotal
Adhesive (polymer) 1500 sqft × rate = subtotal
Grout (cement) 1300 sqft × rate = subtotal
Grout (epoxy) 250 sqft × rate = subtotal
Skirting 280 rft × rate = subtotal
Lift and transport amount
Site supervision days × day rate = subtotal
Breakage allowance amount

TotalAn unreviewable one looks like this:
Tile laying, all rooms, including adhesive, grout and skirting — lump sumThe first can be compared against another contractor's line by line, and each line can be queried. The second cannot be compared against anything, and every omission in it becomes a variation later. Always ask for the line items — a contractor who will not break the number down is telling you something.
Payment terms worth asking for
A structure that protects both sides:
- 20% advance on signing.
- 40% at half completion — floors laid, walls pending.
- 30% on completion.
- 10% retention, released after a 30-day defect-liability period.
The retention clause is the important one. Grout cracks, hairline floor cracks and slope-to-drain problems often only show after two or three weeks of use. Holding a tenth of the value for a month gives both sides a clean, unemotional way to deal with them.
Where we fit
We sell material; we do not run an installation crew, and we do not take a commission on anybody's labour. What we can do is give you a written material quote against your room dimensions or your bill of quantities, with a full GST invoice so the manufacturer warranty is in your name and not somebody else's.
Send us your dimensions or your BOQ and we will come back with a material quote you can hand straight to a contractor.
