Porcelain Paving: The Complete UK Buyer's Guide
Porcelain paving is a factory-made, non-porous outdoor slab that offers zero maintenance, stain resistance, frost-proof performance and colourfast aesthetics. It's the fastest-growing paving material in the UK — but it's not right for every garden. This guide covers everything you need to know before buying: colours, sizes, anti-slip ratings, installation, costs, and the honest pros and cons.
What is porcelain paving?
Porcelain paving is manufactured from refined clay pressed at extremely high temperatures (1,200°C+) to create a dense, non-porous slab designed for outdoor use. Unlike natural stone, which is quarried and cut, porcelain is engineered — every slab is identical in size, thickness, and colour.
The non-porous surface (water absorption under 0.5%) is what gives porcelain its key advantages: stains can't penetrate, water can't freeze inside and crack it, and algae struggles to take hold. It's also what creates its main drawback — the surface retains heat in direct sun because there's no moisture to evaporate and cool it down.
Our porcelain range is 20mm thick, R11 anti-slip rated, and designed specifically for outdoor residential use — not repurposed indoor tiles. Every slab in our range is rated for UK weather, including freeze-thaw cycles, UV exposure, and sustained rainfall.
Choosing a colour
Our porcelain range covers the full spectrum of outdoor colours:
Grey porcelain — the most popular category. Kandla Grey porcelain replicates the look of natural Kandla Grey sandstone but with zero maintenance. Multiple grey tones from warm silver to cool charcoal.
Black porcelain — Anthracite Black and dark charcoal options. Dramatic, contemporary, striking against green planting. Note: dark colours get noticeably hotter in summer sun.
Beige porcelain — warm sand and cream tones. Brightens smaller gardens and pairs well with warm-toned furniture and terracotta planting.
Light porcelain — whites and pale creams including Everest Pearl and Quartz White. Maximum light reflection, stays coolest in summer. Opens up north-facing spaces.
Multi-colour porcelain — stone-effect finishes that replicate the natural variation of real sandstone or travertine. The closest porcelain gets to looking like natural stone.
Stone-effect porcelain — engineered to mimic natural stone textures and grain patterns. The contemporary compromise between natural stone's character and porcelain's performance.
Porcelain colour is consistent across every slab — unlike natural stone where every piece varies. Some people consider this an advantage (predictable, controlled aesthetics), others a disadvantage (lacks natural character). We always recommend ordering a sample to see the colour in your own garden before committing.
Sizes and formats
600×600mm — the classic square format. Best value per m², suits smaller patios, paths, and traditional grid layouts.
900×600mm — the most popular UK paving slab size. Fewer joints, larger visual scale, contemporary feel. Our bestselling porcelain format.
1200×600mm — large format for premium contemporary patios. Minimal joint lines create a sleek, expansive surface. Suits bifold door transitions and architectural gardens.
800×800mm — large square format. An alternative to rectangular slabs for modern grid-pattern layouts.
Patio packs — pre-calculated mix of sizes for a random-pattern layout. Less common in porcelain than sandstone, but available for those who want the mixed-size look with porcelain performance.

Anti-slip ratings explained
Every porcelain slab in our range carries an R11 anti-slip rating — a standardised laboratory test measuring grip under wet conditions. R11 is the recommended minimum for outdoor residential paving in the UK.
The scale runs from R9 (lowest grip) to R13 (highest grip). R10 is acceptable for covered areas. R11 is the standard for open-air patios, paths, and pool surrounds. R12-R13 is typically only required for commercial applications with specific health and safety requirements.
Be cautious of porcelain sold without a stated R-rating — it may be indoor tile repurposed as outdoor paving. Indoor porcelain tiles are thinner (8-10mm vs 20mm), have lower slip ratings, and are not designed for UK freeze-thaw conditions. Read our non-slip porcelain paving guide for more detail on what the ratings mean and how to check them.
Pros and cons
We wrote a dedicated post covering the 7 genuine pros and 7 honest cons of porcelain paving — including the disadvantages most suppliers won't mention. Here's the summary:
Pros: zero maintenance, stain-proof, frost-proof, colourfast, R11 anti-slip rated, precise dimensions for tight joints, consistent colour across every slab.
Cons: gets hot in direct summer sun (48-55°C on dark colours), no natural variation (some find it lifeless), needs a diamond wet cutter for cuts, SBR primer essential or mortar bond fails, replacement slabs must match the original batch, sounds hollow underfoot, shows dirt at joints more than natural stone.
We sell porcelain and sandstone in equal volume. Neither is better — they suit different priorities. Read the full pros and cons breakdown for the detail behind each point.
How much does porcelain paving cost?
Our porcelain paving starts from £19/m² delivered — that's the complete price including VAT and free UK mainland delivery. No delivery charges, no split pallet fees, no extras at checkout.
For a typical 20m² patio, the material cost is approximately £380-450 depending on the colour and size. Add sub-base materials (£200-300), mortar, SBR primer and jointing compound (£100-150), and skip hire (£220-280), and a complete DIY porcelain patio costs approximately £900-1,200 all-in.
Professional installation adds £65-80/m² for labour (porcelain costs slightly more to install than sandstone due to the SBR priming requirement and precision cutting) — making a 20m² professionally installed porcelain patio approximately £2,400-3,200 total.

Installation requirements
Porcelain installation follows the same basic process as natural stone — sub-base, mortar bed, lay, point — but with two critical differences that trip up first-time installers:
1. SBR primer is mandatory. Porcelain is non-porous, so standard mortar won't bond to the back of the slab. Every slab must be primed with SBR (Styrene Butadiene Rubber) bonding agent before laying. Apply the SBR to the back of each slab, wait until it becomes tacky, then lay onto the mortar bed. Skip this step and the slabs will debond and lift within 12-24 months.
2. Cutting requires a diamond wet cutter. You can't cut porcelain with a standard angle grinder — it'll chip, crack, or shatter. You need a diamond wet cutter (tile saw) with a porcelain-specific blade and continuous water cooling. Budget £50-80/day for hire if you don't own one.
Jointing: Use Ultrascape Porcelpoint (£50/tub) — a flowable porcelain grout that self-levels into tight 3-5mm joints. Do not use brush-in compound designed for natural stone — it leaves residue on porcelain that's extremely difficult to remove. Read our complete jointing compound guide.
For the full laying process, our step-by-step laying guide covers the general method. The sub-base and mortar bed process is identical — just add the SBR priming step for porcelain.
Porcelain vs sandstone
This is the most common comparison we get asked about. The short answer: porcelain is maintenance-free and stain-proof. Sandstone has natural character and stays cooler in summer. Material costs are similar (sandstone from £20/m², porcelain from £19/m²).
The real difference is ongoing: sandstone benefits from sealing every 3-5 years and annual cleaning. Porcelain needs neither — ever. Over 20 years, porcelain's zero maintenance cost roughly offsets any upfront price difference.
We import and sell both. Read our honest sandstone vs porcelain comparison for the full breakdown including 7 scenarios that tell you exactly which material suits your situation.
Edging options for porcelain patios
Porcelain patios benefit from a defined border — the uniform surface looks better with a frame. The most popular options:
Porcelain edging planks (900×200mm or 900×150mm) — matching or contrasting colour creates a clean picture-frame effect. Anthracite Black planks around Kandla Grey porcelain is our bestselling edging combination.
Porcelain bullnose copings — rounded-edge slabs for raised patios and step fronts. The professional finish for any raised or stepped porcelain patio.
Granite setts — natural stone border around a porcelain centre creates an attractive material contrast. The natural granite texture against smooth porcelain adds visual depth.

Does porcelain get hot in summer?
Yes — this is the con most suppliers don't mention. Dark porcelain in direct afternoon sun can reach 48-55°C, making it uncomfortable for barefoot walking. Light-coloured riven sandstone stays 10-15°C cooler in the same conditions.
Solutions: choose a lighter colour (light grey or white porcelain runs 5-8°C cooler than black), add shade over seating areas, hose the patio before use, or use outdoor rugs in barefoot zones.
If your patio is south-facing with full afternoon sun and you walk barefoot regularly, this genuinely matters. If it's shaded, north-facing, or you wear shoes outdoors, the heat difference is irrelevant. Read our full paving heat comparison with temperature ranges for every material.
Porcelain paving FAQs
Is porcelain paving worth it?
For most UK patios, yes. The zero-maintenance benefit alone justifies porcelain for homeowners who don't want to seal, treat, or scrub their patio annually. The genuine downsides (heat in sun, hollow sound, SBR requirement) are trade-offs, not dealbreakers. Read our full pros and cons.
How long does porcelain paving last?
30+ years with proper installation. The porcelain itself is virtually indestructible — it won't fade, stain, crack from frost, or deteriorate from UV. The limiting factor is the sub-base and mortar bed beneath it, not the slab itself.
Can you lay porcelain paving on sand?
No. Porcelain must be laid on a compacted MOT Type 1 sub-base with a full mortar bed and SBR primer. Laying on sand causes movement, joint failure, and cracking. The sub-base is non-negotiable — read our sub-base guide.
What is R11 anti-slip rating?
R11 is a standardised laboratory test measuring surface grip under wet conditions. It's the recommended minimum rating for outdoor residential paving in the UK. All porcelain in our range is R11 rated. Avoid porcelain sold without a stated R-rating — it may be indoor tile not designed for outdoor use. See our non-slip porcelain guide.
Does porcelain paving need sealing?
No — never. Porcelain is non-porous (water absorption under 0.5%), so sealant has nothing to bond to and serves no purpose. This is one of porcelain's biggest advantages over natural stone, which benefits from sealing every 3-5 years.
What jointing compound should I use for porcelain?
Use a flowable porcelain grout like Ultrascape Porcelpoint (£50/tub). It pours into tight porcelain joints and self-levels without staining the surface. Never use brush-in compound designed for natural stone — it leaves residue on porcelain. Read our jointing compound guide.
Is porcelain cheaper than sandstone?
Material costs are similar — our porcelain starts from £19/m², sandstone from £20/m². Installation costs slightly more for porcelain (SBR priming adds time, cutting requires specialist equipment). Over 20 years, porcelain's zero maintenance cost makes it roughly equal or cheaper overall. Read our full comparison.
Can porcelain paving be used on driveways?
Yes — 20mm porcelain is rated for vehicular use when installed on a properly prepared sub-base (minimum 200mm compacted MOT Type 1) with a full mortar bed and SBR primer. Read our driveway paving guide.
