The short answer
Indian sandstone is an affordable, characterful natural stone with a riven (split) surface and warm colour variation, while porcelain is a dense, fired-clay slab that is highly stain-resistant and colour-stable. The trade-offs are clear. Indian sandstone is usually cheaper to buy, easy to work and has a natural, rustic look, but it is porous, so it can stain, weather and green up, and benefits from sealing. Porcelain is low-maintenance, stain-resistant and fade-proof with a uniform finish, but it costs more to lay because the slabs need a full mortar bed, a slurry primer and diamond-blade cutting. Sandstone suits a traditional, budget-friendly patio; porcelain suits a contemporary, easy-care one. Both perform well when laid properly.
Indian sandstone and porcelain dominate UK patio choices, so they are often compared directly. This page sets them side by side on cost, upkeep and looks.

What they are and how they look
The two materials offer quite different characters.
- Indian sandstone is a sedimentary natural stone quarried in India and widely imported to the UK. It typically has a riven (naturally split) surface with texture and grip, and comes in warm, varied tones — buff, grey, brown, multicolour — with each slab unique. Thickness can be calibrated or vary slightly.
- Porcelain is manufactured from fine clays pressed and fired at very high temperatures into a dense, hard slab of consistent thickness (commonly 20mm outdoors). Surface designs can imitate stone, wood or concrete, and the colour is uniform from slab to slab.
So the look is a genuine fork in the road: sandstone gives natural variation and a traditional, rustic feel that weathers over time, while porcelain gives a crisp, consistent, contemporary finish that stays the same. Many homeowners choose between them on aesthetics alone before cost and upkeep even enter the picture.
Durability, staining and maintenance
On porosity and staining, porcelain wins. Its near-zero water absorption means spills wipe off and algae and moss struggle to take hold, with no sealing usually required. Indian sandstone is more porous, so it can absorb stains (oil, wine, leaf tannins), green up in damp shade, and is commonly sealed to reduce absorption and ease cleaning.
On colour and weathering, porcelain holds its colour and will not fade. Sandstone weathers and develops a patina, which some prize as character and others see as a drawback.
On durability and frost, porcelain's density makes it very hard-wearing and frost-resistant. Good Indian sandstone is durable too, but as a porous stone it can be more affected by freeze-thaw if water penetrates, and softer batches may be less robust — quality varies, so source carefully.
On slip resistance, riven sandstone's textured surface is naturally grippy. Porcelain must be specified with an outdoor slip-resistant finish (R11 or higher); some smooth porcelain is too slippery when wet for a patio.
On maintenance, porcelain is the lower-effort option — easy cleaning, no sealing, good moss resistance — while sandstone needs periodic cleaning and sealing and may green up more.
| Factor | Indian sandstone | Porcelain |
|---|---|---|
| Material cost | Often lower | Higher |
| Laying cost | More forgiving, lower | Full mortar bed + primer, higher |
| Porosity / staining | Porous; can stain | Very low; stain-resistant |
| Sealing | Often recommended | Rarely needed |
| Colour over time | Weathers, patina | Stable, no fade |
| Slip resistance | Grippy (riven) | Specify R11+ finish |
| Look | Natural, rustic, varied | Uniform, contemporary |

Cost, laying and which suits your garden
On cost, Indian sandstone is frequently the more affordable choice to buy, which is a big part of its popularity, and it is cheaper to lay because it is forgiving to cut and bed. Porcelain materials cost more, and crucially the installation costs more too: outdoor porcelain needs a full mortar bed (not spot-bedding), a slurry primer on the back of each slab for adhesion, and diamond blades to cut cleanly. Over a whole patio that adds up.
Laying reflects this. Sandstone tolerates a range of techniques and accommodates minor thickness variation. Porcelain is unforgiving and rewards an experienced installer — poor bedding or adhesion can lead to hollow, cracked or lifting slabs.
Which suits your garden? Choose Indian sandstone for a traditional, characterful, budget-friendly patio where you accept sealing and weathering. Choose porcelain for a contemporary, uniform, low-maintenance, stain- and fade-resistant surface where you are willing to pay more for the slabs and the more demanding installation. Both make excellent patios; the decision turns on the look you want, your budget, and how much ongoing upkeep you are prepared to do.
Living with each surface over the years
Beyond the initial choice, it helps to picture how each material behaves through years of British weather and use, because that is what you actually live with.
Indian sandstone develops character. Its colour mellows and the surface gains a weathered, settled look that many homeowners love on a traditional or cottage-style garden. The flip side is that, as a porous stone, it can pick up stains from barbecues, planters, leaf tannins and spilled food and drink, and it can green up with algae in damp, shaded spots. Sealing reduces — but does not eliminate — this, and may need renewing over time. Routine care is a periodic gentle clean and re-sealing; aggressive pressure washing can erode the surface and strip sealer, so a softer approach is better. Occasional efflorescence (a temporary white bloom of mineral salts) can also appear on new natural stone and usually weathers away.
Porcelain stays largely as it started. Because it absorbs almost no water, stains sit on the surface and wipe off, algae and moss gain little foothold, and the colour does not fade. Day-to-day care is simple sweeping and washing, with no sealing required. The main things to watch are keeping the joints clean and intact, and choosing a slip-resistant outdoor finish from the start so the surface stays safe when wet. Porcelain's hardness also means it resists scratching and scuffing from furniture well.
Repairs. A damaged sandstone slab can be lifted and replaced, though matching the colour of natural stone exactly can be tricky given its variation. A cracked porcelain slab can also be replaced, and because porcelain is uniform the match is usually closer — provided the same range is still available. For both, a small reserve of spare slabs kept after installation makes future repairs far easier. Over a full lifespan, both materials reward correct laying and sensible care; the choice between them remains largely about whether you prefer natural character that weathers or a uniform finish that stays put.
A useful way to settle it is to weigh upkeep tolerance against budget and look. If you want the lowest ongoing effort and a crisp, unchanging finish, and can absorb the higher slab and installation cost, porcelain is the natural fit. If a warmer, traditional feel and a lower spend matter more, and you accept periodic sealing and some weathering, Indian sandstone earns its long-standing popularity. Neither is objectively superior — they simply reward different priorities, and both deliver a patio that lasts when laid and cared for properly.
Frequently asked questions
Is Indian sandstone cheaper than porcelain?
Usually yes, both to buy and to lay. Indian sandstone materials are often more affordable, and it is more forgiving to cut and bed. Porcelain costs more for the slabs and for installation, which requires a full mortar bed, a slurry primer and diamond-blade cutting.
Does Indian sandstone need sealing?
It is commonly recommended. As a porous natural stone, Indian sandstone can absorb stains and green up in damp conditions, so sealing reduces absorption and makes cleaning easier. Porcelain, by contrast, is very low porosity and rarely needs sealing.
Is porcelain more slippery than sandstone?
It can be if the wrong finish is chosen. Riven Indian sandstone is naturally textured and grippy. Outdoor porcelain should be specified with a slip-resistant finish (R11 or higher); smooth indoor-style porcelain can be too slippery when wet for a garden patio.
