Indian sandstone vs porcelain paving: a 10-year cost comparison
Five years ago, Indian sandstone was the default patio material in the UK. Today, porcelain paving accounts for roughly 40% of our domestic paving orders — and the gap is closing fast. The question we get most often: is the price difference actually worth it over the life of the patio?
Upfront cost: sandstone still wins
Calibrated 22 mm Indian sandstone landed at the average UK builder's merchant runs roughly £24–32 per m² depending on colour. 20 mm vitrified porcelain paving in equivalent formats is typically £38–60 per m². For a 40 m² patio, you're looking at a £600–£1,200 material premium for porcelain.
Installation is also slightly cheaper for sandstone — the wider tolerance for slip and lippage means a less-experienced team can lay it acceptably. Porcelain demands a full mortar bed and primer, with no margin for variation.
Year 1–3: the gap narrows
Indian sandstone needs sealing in year 1 to resist staining (BBQ oil, red wine, leaf tannins) and ideally re-sealing every 2–3 years. A 5L tub of solvent-based impregnator covers ~25 m² and costs £45–60. Over a decade, you're looking at 3–4 reseal cycles plus annual jet-washing.
Porcelain needs none of that. Wipe with a stiff brush or hose; that's it. No sealing, no annual reseal, no staining anxiety.
Year 5–10: where porcelain pulls ahead
Algae and moss are the long-term killers of sandstone in shaded UK gardens. Even sealed slabs darken visibly within 4–5 years. The remediation — bleach wash, pressure clean, reseal — runs around £8–12 per m² if done professionally.
Porcelain's vitrified surface is essentially impermeable, so it stays the colour you bought it. After 10 years, the total cost-of-ownership often crosses over: sandstone ends up costing more once maintenance, resealing, and the inevitable replacement of frost-damaged slabs are tallied.
Which to spec, when
Choose Indian sandstone when budget is tight, the patio is in full sun (limits algae), and the homeowner accepts annual maintenance. The riven texture also fits traditional and cottage-style gardens better than porcelain.
Choose porcelain for shaded patios, north-facing aspects, contemporary designs, around pools (zero slip when wet on R11-rated finishes), and any client who explicitly wants "set and forget". For commercial public-realm work, porcelain has effectively become the only sensible spec.
