Smooth Sandstone Paving: Complete UK Buyer's Guide 2026
Right, let's talk about smooth sandstone. Because there's a massive difference between the rustic, natural-split riven finish that's been everywhere for two decades and the clean, contemporary look of properly honed smooth Indian sandstone.
Smooth sandstone paving—also called sawn and honed sandstone—has quietly become the choice for people who want natural stone character without looking like they're recreating a medieval courtyard. This guide tells you everything you actually need to know about buying, choosing, and living with smooth sandstone for UK patios and gardens.
What Makes It "Smooth" (And Why It Matters)
Let's clear this up first because "smooth" doesn't mean polished-like-a-mirror. It means the surface has been sawn flat and then honed to create an even, gently textured finish.
The sandstone blocks are cut with diamond saws, ground down to remove saw marks, then honed to create that consistent surface. You end up with slabs that are flat, even, and far less rustic than riven stone—but still with enough texture to be safe underfoot when it's chucking it down (which, let's face it, is often).
The result? A contemporary surface that looks intentional and designed rather than randomly textured. Your furniture doesn't wobble, your dining table sits level, and the whole patio feels more like an outdoor room than a garden path.
Smooth vs Riven: Making the Right Choice
Everyone asks this question, so let's be straight about it.
If you've got a modern house with grey window frames and clean lines, buy smooth sandstone paving without overthinking it. The honed finish complements contemporary architecture perfectly. It's also brilliant for anyone who wants to actually use their patio for entertaining—tables sit flat, chair legs don't catch on uneven surfaces, and cleaning is infinitely easier.
Riven sandstone, with its heavily textured natural split surface, suits traditional properties and cottage gardens beautifully. It's more forgiving of imperfections and hides dirt better. But if you're after that sleek, modern aesthetic or you're creating an outdoor dining area, smooth honed sandstone paving wins every time.
Neither's wrong—it's about matching material to context. But if you're reading this, you've probably already decided smooth feels right for your space.
Choosing Your Colour (Real Talk)
This is where people get stuck scrolling through Pinterest at midnight. Let me walk you through what Universal Paving UK stocks and what actually works in British gardens.
Kandla Grey smooth sandstone has become the default contemporary choice, and there's good reason for that. Those blue-grey tones with subtle variation work with pretty much any modern property. My mate Dave just laid Kandla Grey around his new extension in Sheffield—looks absolutely mint with the anthracite bi-folds. You're looking at £26.79/m² for 900x600mm slabs, or grab the patio pack at £25.27/m² if you want mixed sizes for more visual interest.
The thing about Kandla Grey is it doesn't show every coffee spill or muddy paw print like lighter stone does. Practical if you've got kids or dogs, and it photographs beautifully too (if you're the Instagram garden type).
Fossil Mint smooth sandstone is the choice for people who want something a bit different. Soft green-grey tones with actual fossil details embedded in the stone—proper conversation starter material. Works gorgeously in gardens with loads of planting where that subtle green undertone ties everything together. At £26.24/m² for 900x600mm, it's competitively priced for something genuinely distinctive.
I saw a courtyard garden in Nottingham last month where they'd used Fossil Mint—surrounded by ferns and Japanese maples, it looked like it had always been there. That's the magic of the mint tones.
Rippon Buff smooth sandstone is your classic British honey-coloured stone, just with a contemporary smooth finish. If you've got a red brick house or anything Cotswold-adjacent, this is your safe bet. The warm caramel tones have worked for centuries and won't suddenly look dated when trends shift. £27.67/m² for 900x600mm, and worth every penny for that timeless appeal.
Raj Green smooth takes the wild multi-tonal chaos of traditional Raj Green riven and tames it with the smooth finish. You still get those gorgeous plum, rust, sage, and golden hues, but it looks contemporary rather than rustic. Perfect if you want colour without your patio looking like a crazy paving experiment gone wrong. £27.89/m² gets you proper character with modern sophistication.
Camel Dust smooth sits somewhere between buff and grey—the diplomatic choice that works with everything. If you're genuinely stuck between warm and cool tones, this bridges the gap nicely. £28.99/m² for 900x600mm.
Size Matters (More Than You'd Think)
The 900x600mm format has become standard for good reason—it's large enough to look contemporary and reduce grout lines, but manageable enough to actually handle and install without hiring a crane. This is your default choice unless you've got specific design reasons otherwise.
Patio packs mix 900x600, 600x600, 600x300, and 300x300 in pre-calculated ratios. Creates more visual interest through size variation and often works out slightly cheaper per square metre. The Kandla Grey patio pack at £25.27/m² is cracking value.
If you want to go big, Universal Paving stocks 1200x600mm Kandla Grey smooth at £27.48/m². Very contemporary, makes spaces feel larger, but each slab weighs a proper amount—not a solo lifting job.
Linear planks (900x200mm) work brilliantly for borders, pathways, or creating directional flow. I've seen them used to frame a main patio area in contrasting colour—really sharp look.
What You'll Actually Pay (Realistic Numbers)
Let's work through a typical 30m² patio because vague price ranges are useless.
Using Kandla Grey patio pack at £25.27/m²: you need 30m² plus 10% wastage (always order extra, trust me). That's 33m² total, which comes to £833.91 in materials.
If you're hiring someone to lay it—and unless you're genuinely handy, you probably should for your first patio—figure £40-60/m² for labour depending on where you are in the UK. London and Southeast hits the higher end; Midlands and North are more reasonable. At £50/m² average, that's £1,500 for a 30m² installation.
Base work if you're starting from scratch: £200-300 for MOT Type 1 sub-base, another £150-200 for the sand and cement bed.
Total realistic cost for a professional 30m² smooth sandstone patio: £2,683-£2,833.
That's competitive with porcelain (which would cost £2,000-3,000 just in materials) and you're getting actual natural stone with character that improves with age.
The Slip Question Everyone Asks
"Is smooth sandstone slippery when wet?" comes up in every conversation.
Honest answer: it's less grippy than heavily riven stone, but it's still perfectly safe for UK outdoor use. The honed surface keeps enough texture to provide grip—it's not like polished marble where you're ice-skating across your patio.
Make sure you've got proper drainage falls (minimum 1:80 gradient away from the house), keep the surface clean (it's algae that makes things slippery, not the stone), and avoid sealers that create glossy films. Common sense stuff.
Thousands of UK patios use smooth honed Indian sandstone without anyone ending up in A&E. Just don't treat it like an ice rink and you'll be fine.
Maintenance: The Actual Truth
This is one of smooth sandstone's biggest selling points—it's genuinely low-hassle compared to riven stone.
Weekly sweep to clear leaves and debris. Pressure wash once or twice a year. Treat any moss or algae when you spot it. That's basically it.
The smooth surface doesn't trap dirt in crevices like riven does, so cleaning is quicker and more effective. Spills wipe off easier too—red wine on smooth sandstone? Soapy water and a brush sorts it. Same spill on heavily textured riven? Good luck getting into all those little ridges.
Should you seal it? Controversial opinion: probably not unless you're obsessive about maintenance. Sealed stone needs resealing every 2-3 years, can look patchy if done poorly, and adds ongoing cost. Unsealed natural stone develops a beautiful patina over time. Your choice, but I'd let it age naturally.
Common Mistakes to Dodge
Skimping on base prep causes 90% of paving failures. You need 100-150mm of properly compacted MOT Type 1 sub-base. No shortcuts. This isn't where you save money.
Not ordering enough from the same batch means colour mismatches that'll bug you forever. Always order 10% extra from the identical batch. Stone varies naturally between production runs.
Using the wrong jointing material causes problems later. Spend the extra on proper kiln-dried sand or resin pointing. Cheap builders' sand washes out and weeds appear.
Ignoring drainage creates standing water and accelerates weathering. Minimum 1:80 fall away from buildings. Not negotiable.
