Concrete effect worktop or porcelain: which is the real thing?

A concrete effect worktop in porcelain is a picture of concrete, printed on a ceramic slab. Real concrete is concrete all the way through, cast to your room and sealed. If you're choosing between the two, that's the whole difference, and a sample in your hand shows it in a minute.

What is a concrete-look porcelain worktop?

It's a porcelain slab with a concrete pattern on its face. One UK supplier says the design is "applied through digital printing before firing", and that porcelain worktops usually come as 12mm or 20mm slabs. Porcelain is a good material and it does what it says. It just isn't concrete, any more than a granite-look print is granite.

Why is it sold as the easy option?

The pitch is upkeep. An AOL feature on the trend, from March 2026, says of porcelain tile that "unlike concrete, it will not stain". That's a fair point about concrete left unsealed. Ours never is.

Every ROKA top is sealed with SureCrete XS-327, a two-part, water-based hybrid polyurethane that penetrates the surface. The maker rates it stain resistant to most household chemicals and food. Water beads on it, it's UV stable, and it's rated to 149°C, so a pan of boiling pasta goes straight down.

Check the seal once a year. If water stops beading, it's due a recoat, and a worn patch is lightly sanded and recoated where it sits. Nobody takes the top out. Put red wine, lemon and olive oil on a sample overnight and see for yourself.

What does real concrete give you that a print can't?

Depth first. The colour is in the concrete itself, not painted on. There are nineteen named colours, from Chalk and Dove to Graphite and Terracotta, and we'll match a custom colour too. There are two standard finishes. Cream comes straight from the mould and is sealed, with the deepest colour. Salt and pepper is diamond-finished to 800 grit, so fine sand shows.

Then shape. A ROKA top is cast to your drawings, so the thickness is yours to choose. The designer offers 30 to 50mm, and quoted work goes thicker. A sink can be cast into a made-to-size top, with drainer grooves beside it. In a barn kitchen in Steyning we cast a waterfall island in one piece, on site, in GFRC.

That's what casting does. A cast piece is made to fit your room. The designer makes pieces up to 3m long and 1.2m deep, and quoted work has no fixed maximum.

How much does a cast concrete worktop cost?

Worktops are £850 per m² up to 30mm thick, then £15 more per m² for every millimetre above that. So 40mm is £1,000 per m², and every named colour costs the same. Typically a top takes 3 to 6 weeks from design sign-off. On quoted work, templating, delivery and fitting are priced on top, with the drawing.

Behind it sits the ROKA 5-Year Guarantee. If a piece we make fails through our fault in its first year, we remake it, and up to year five we repair it.

How do you choose between them?

Hold both, if you can. We post ours free. Put them next to your cabinets and your floor, in your own light.

You'll feel the difference before you can explain it. Order free samples, and when you're ready to see what we cast, start at the concrete worktops page.

Concrete is concrete and porcelain is porcelain. One is a picture of the other.
