Schock is a German kitchen sink manufacturer producing premium composite granite sinks under their Cristalite brand — widely distributed through UK kitchen retailers and fitted in tens of thousands of UK homes. When a Cristalite sink chips, professional repair is available on-site at a fraction of the replacement cost.

What Is Schock Cristalite?

Cristalite is Schock’s composite granite material — quartz and granite particles in a resin matrix. It has a distinctive appearance — consistent, fine-textured, with a slight depth to the surface. Schock are particularly known for their precise colour formulations and the durability of their Cristalite material.

Schock Cristalite Colours We Repair

Schock produces Cristalite in a range that spans from classic neutrals to contemporary tones:

Onyx (Black) — the most popular current colour. Deep uniform black. Very straightforward to repair.
Silverstone — dark metallic grey. Good match achievable.
Magma — deep anthracite. Good results.
Moonstone — light grey-white. Straightforward repair.
Vanilla — warm cream-white. Matchable.
Asphalt — dark charcoal. Good results.

For discontinued or unusual Schock colours, we match from the physical colour — send photos and we will confirm.

Where Schock Sinks Chip

The Cristalite material is harder than many competitors but not chip-proof. The most common chip locations are:

Front rim edge where it meets the worktop cutout
Tap hole apertures (particularly when taps are changed)
The base of the bowl from heavy pan impact

Cost

Single chip repair: £85–£165
2–3 chips in one visit: £150–£265

Compare to a new Schock sink: £250–£600 plus fitting (£100–£250). Total replacement: £350–£850. A chip repair saves 75–90%.

Frequently Asked Questions

Schock claim Cristalite is scratch and chip resistant — how did it chip?
Cristalite is highly chip-resistant compared to standard ceramics or stainless steel. However, no material is chip-proof under sufficient impact force. A full cast iron pan dropped from height will chip any composite sink.
Can you repair the Cristalite texture precisely?
Yes. The slightly textured, matte-rich surface of Cristalite is distinctive and our technicians replicate it in the repair finish.
