Ask three suppliers for a price on the same marble and you will get three numbers that look comparable and are not. The figure being quoted is almost always the material rate — the slab, ex-yard, before anything is done to it. On a finished commercial floor, that rate is typically somewhere between 40% and 55% of what the square metre eventually costs the project.
The other half is not hidden. It is simply on different lines, in different packages, and often in a different budget holder’s file. This article puts the whole square metre on one page: what each line typically contributes, where the averages sit in the Saudi market, and how to compare two quotations without being misled by the only number both of them show you.
The seven cost lines in a finished square metre
The shares below are indicative averages for a commercial interior floor in polished natural marble. They shift with the material, the layout and the area — a bookmatched feature wall inverts several of them — but the shape holds often enough to be useful as a first check on any quotation.
| Cost line | Typical share | What moves it |
|---|---|---|
| Material, ex-yard | 40–55% | Stone type, block quality, origin |
| Fabrication and cutting | 8–15% | Piece sizes, edge profiles, cut-outs |
| Wastage | 5–15% | Layout complexity, vein matching |
| Freight, handling, storage | 4–10% | Origin, packing, site access |
| Installation labour and materials | 15–25% | Substrate condition, adhesive grade, joints |
| Sealing and protection | 2–5% | Porosity, programme overlap with other trades |
| First-year maintenance | 2–4% | Traffic class, cleaning regime |
Two observations follow immediately. First, a supplier who shaves 10% off the material rate has moved roughly 5% of the finished cost. Second, wastage and installation together can swing wider than the entire material saving that was negotiated to win the job.
What the material rate actually reflects
Market reporting on the Kingdom’s stone sector gives a clearer picture than a single headline rate. According to Arab News coverage of the Saudi stone market, locally quarried beige marble commonly sells in the region of SR200 to SR600 per square metre, while premium local white varieties run from SR600 up to SR5,000. Imported Italian marble typically starts at around €100 — roughly SR450 — per square metre, with Statuario and Calacatta exceeding €1,200.
The same reporting notes two things worth carrying into a specification. White and beige split the Saudi market roughly evenly, and marble accounts for up to half of interior projects — while granite, quartzite and limestone are preferred on external facades for their resistance to the climate. A design that specifies marble on a south-facing facade is fighting both the market and the weather.
Treat all of this as a range, not a price list. Within a single commercial name, the spread between a commercial-grade block and a first-selection block can be larger than the gap between two different stones.
What you are paying for inside that band is mostly:
- Block selection. Crack density, staining and vein consistency determine how much of a block becomes usable first-quality slab.
- Slab size and thickness. Larger formats and thicker slabs cost disproportionately more, because they constrain which blocks can produce them.
- Resin and reinforcement. Standard on many marbles, but the quality of the treatment varies and shows up years later.
- Origin and logistics. Two stones with similar technical data can differ substantially once freight and lead time are priced in.
The comparison that matters is not price per square metre but price per accepted square metre — material that passes the consultant’s sample range and arrives within tolerance. A cheaper rate with a 20% rejection risk is not cheaper.
Fabrication and wastage: the line that moves most
Wastage is where quotations diverge most and get compared least. A simple rectangular floor laid in a running bond wastes little. The same area with a defined vein direction, a border, several column cut-outs and a bookmatched threshold can waste several times that.
Ask for the wastage percentage to be calculated from the actual cutting plan and shown as a separate line. Two things follow: the number becomes auditable, and any later shortfall can be traced to a document rather than argued from memory. A quotation that folds wastage silently into a single rate is not cheaper — it is less legible.
Installation: the second-largest line
Installation labour in the Kingdom is commonly quoted in the region of SAR 60 to 120 per square metre for labour alone, according to Benna’s guide to marble flooring in Saudi Arabia, with the spread driven by substrate condition, piece size and the difficulty of the layout. Add adhesive, grout, levelling compound, movement joints and protection, and the installed package routinely lands in the 15–25% share shown above.
This line also carries the project’s largest hidden risk. Substrate preparation that is priced out of the job does not disappear; it reappears as hollow slabs and cracking, which is the mechanism described in practical solutions for marble cracks and surface peeling. The cheapest installation quotation is frequently the one that assumed a level floor nobody has measured.
Protection, sealing and the first year
Two costs sit here, and both are routinely omitted at tender stage.
Temporary protection. If marble is installed before other trades finish, it has to be covered — and the covering has to breathe, or it traps moisture against a freshly laid floor. Skipping it produces scratching and cement staining discovered at snagging, when the trades responsible have demobilised.
Sealing and initial maintenance. A penetrating impregnator plus a defined cleaning regime for the first year. This is a small percentage that protects a large one: acidic cleaners etch calcium carbonate, and the damage is rarely repairable without honing the surface back.
The twenty-year view
Comparing a natural stone floor to an engineered alternative on day-one cost answers the wrong question. The honest comparison runs over the operating life and includes the replacement cycle.
| Horizon | Natural marble | Engineered marble |
|---|---|---|
| Day one | Higher | Lower |
| Periodic treatment | Re-seal and re-polish on a traffic-driven cycle | Generally none required |
| Repairability | Localised repair possible from attic stock | Often replacement of the affected run |
| Expected service life in heavy traffic | Decades with maintenance | Shorter; replacement cycle likely |
| Twenty-year position | Frequently lower total | Depends on replacement count |

How to compare two quotations honestly
Normalise before comparing. Put both offers on the same eight lines and the winner often changes.
- Is the rate ex-yard, delivered to site, or installed? Convert all offers to the same basis.
- What thickness and finish is quoted, per area?
- Is wastage included, and is it stated as a separate percentage?
- Is attic stock included, and how much?
- Is the full quantity from one reserved batch?
- Who bears freight on rejected material, and what is the replacement lead time?
- Is fabrication to an approved cutting plan included, or priced later?
- Is technical support during installation included or chargeable?
Question five is the one that most often separates a real offer from an optimistic one. A price that assumes material will be available later, at the same appearance, is a price with an unpriced risk attached to it.
Frequently Asked Questions
Why do two quotations for the same marble name differ so much?
Because the commercial name describes the appearance, not the selection grade. Two offers for the same stone can be quoting different block qualities, different slab thicknesses, different resin treatments and different origins. Ask which block or lot each price refers to, and ask to see slabs from it — the difference usually becomes visible immediately.
Should the material and installation be bought from the same party?
Not necessarily, but the interface has to be owned by someone. When supply and installation sit with different contractors, the substrate tolerance, adhesive specification and handling responsibility must all be written down, or each party will assume the other priced it.
How much attic stock should be priced in?
Enough to repair localised damage years later, held from the same batch and stored properly. It is one of the cheapest lines in the whole build-up and one of the most valuable, because without it a single cracked slab in a lobby becomes either a visible mismatch or a full replacement.
Are the figures in this article fixed prices?
No. Every figure here is an indicative average drawn from published market guidance, included so that a quotation can be sanity-checked against a reference point. Actual pricing depends on the specific block, quantity, thickness, origin and programme, and should always be confirmed against a current offer for your own scope.
