Portico Gris Porcelain Paving brings a clean, contemporary mid-grey tone to outdoor spaces, drawing on the palette of natural slate and weathered stone. Stocked right here for the UK market, these premium 20mm outdoor slabs provide a high-end, architectural finish for patios, pathways, and trade landscaping projects.
Portico Gris is a 20mm outdoor vitrified porcelain slab in a balanced mid-grey tone that suits both modern urban gardens and more traditional courtyard settings. In the highly popular 600x900mm large format, it creates a seamless, expansive look with fewer grout lines, giving outdoor spaces a structured, considered feel. It sits alongside our Portico Beige and Portico Taupe options.

Want the same grey tone in genuine natural stone instead? Kandla Grey Sandstone offers a comparable grey-blue palette with real natural texture and variation. However, you should choose Portico Gris if a consistent, low-maintenance grey matters more than natural variation. Porcelain won't stain, fade, or need any sealing to keep that clean, architectural look.

What sizes does Portico Gris come in?
It is available in 600x600mm, 600x900mm, and 800x800mm formats, all in a durable 20mm thickness.
Is there a matching tile in a different shade?
Absolutely. If you are looking for warmer or earthier tones, check out Portico Beige and Portico Taupe.
Is Portico Gris suitable for UK winters?
Yes. Because vitrified porcelain has extremely low water absorption, it is highly frost-resistant. Water cannot penetrate the slab to freeze and crack it.
How does Portico Gris compare to grey sandstone?
While natural sandstone offers genuine natural texture and colour variation, it requires periodic sealing. Portico Gris gives a consistent, architectural grey with virtually no maintenance.
Can I order a sample of Portico Gris?
Yes, we highly recommend it! You can request a free sample directly through our website to check the colour against your garden's lighting.
