Marble, travertine, slate, limestone, granite — no two alike. Typical installed cost, durability, where it works and how to care for it.
Natural stone is quarried, cut and finished rather than manufactured, so every piece is unique and no digital print can fully replicate it. That uniqueness is the entire value proposition. Behavior varies enormously by stone type: granite is dense and nearly bulletproof, slate is durable and naturally slip-resistant, marble and limestone are calcium-carbonate stones that etch on contact with anything acidic, and travertine is porous with natural voids that are usually filled at the factory. All natural stone requires periodic sealing.
Calcareous stones (marble, limestone, travertine, onyx) react with acid and etch — a dull mark that is physical damage, not a stain. Siliceous stones (granite, slate, quartzite, sandstone) are acid-resistant.
A stain is absorbed material and can often be drawn out with a poultice. An etch is dissolved surface and requires re-polishing. Sealer prevents stains; it does not prevent etching.
Polished (reflective, slippery when wet, shows etching most), honed (matte, hides etching, needs sealing more often), tumbled and brushed (textured, best slip resistance).
Impregnating (penetrating) sealers sit below the surface and do not change appearance — the standard choice. Topical sealers add sheen but wear and must be stripped.
Order 10–15% overage and dry-lay the entire floor before setting to distribute color and veining. Stone that is not laid out first frequently looks blotchy.
Stone is heavy. Verify floor framing and deflection, especially for thick slabs and second-floor applications.

If you want marble in a kitchen, decide up front that you love patina. Etching in a working kitchen is inevitable, not a maintenance failure.
Each feature paired with the benefit it delivers. A spec on its own tells you nothing about whether it is worth paying for.
Every piece is unique and no printing process can replicate it. That uniqueness is the entire value proposition and it does not date.
Marble and granite can be honed and re-polished repeatedly, so a 100-year-old stone floor is restored rather than replaced.
Holds warmth from a radiant system and stays cool in summer heat, which is why it is traditional in hot climates.
The right stone runs from an interior hall out to a terrace with no change of material, which no printed product can honestly imitate.
Polished, honed, tumbled and brushed produce dramatically different looks and slip performance from the same quarried block.
Drawn from the same ratings used everywhere else on this site, so this cannot flatter the product beyond what the comparison table says.
The specifications below decide how this floor performs. Ask for them in writing — a sample board and a price per square foot do not tell you any of it.
Natural Stone runs $11.00–$50.00 per square foot installed in 2026 — $4.00 to $30.00 for material and $7.00 to $20.00 for professional labor. Spread across an expected 50 to 100 year service life that works out near $0.41 per square foot per year. Regional variation of 20 to 40% is normal, and demolition, subfloor prep and trim are extra.
50 to 100 years, assuming it went into an appropriate room over a properly prepared substrate and gets the maintenance it needs. If you want marble in a kitchen, decide up front that you love patina. Etching in a working kitchen is inevitable, not a maintenance failure.

No. Standing water causes permanent damage. Keep it out of wet areas.
Dust-mop daily — grit scratches polished stone quickly. Clean only with a stone-specific neutral cleaner. Critically: never use vinegar, lemon, bleach or generic bathroom cleaners.
