Cost: indoor natural stone flooring
The supplied reference, formats, layout and substrate determine the budget. Compare these and justified treatments rather than presumed rankings between stone families.
Editorial update on 18 September 2026
Compare identifiable supply
Record stone, origin, finish, sizes, purchased quantities and spares. Compare selection and accepted variation. An unproven local label does not justify short delivery or a premium.
Separate preparation and fabrication
Separate removal, repairs, assembly, cutting and skirting. Include vein layout, bespoke thresholds and handling constraints rather than unexplained percentage supplements.
Separate useful protection from options
Ask why each treatment is proposed, its timing and limitations. Specify final cleaning and instructions. Do not impose water repellent, polishing and fixed renewal intervals on every stone.

Frequently asked questions
Does water repellent protect marble from acid?
Do not assume so. Stain treatments have limits and do not remove the stone’s chemical sensitivity.
Does blue stone mean Luxembourg stone?
No. Request origin of the actual supplied product.
Is a matt finish enough in a bathroom?
No. Check slip behaviour, permitted use and waterproofing separately.
Should every stone be crystallised?
No. The method must match stone type and condition.
Is treatment needed immediately after installation?
Not automatically. Check need, compatibility and drying before application.
