River stone · 07.01
Small, smooth, naturally rounded pebbles in warm earth tones. Easy on bare feet and suited to paths, garden beds, drainage and the gaps between stepping stones.
Quick answer
20mm River Stone is a small decorative pebble, smooth and naturally rounded, in browns, yellows, reds, whites and greys. It’s easy to walk on, handles heat and won’t alter your soil chemistry, so it suits garden paths and beds, lighter-traffic driveways, pond edges and drainage. Spread it about 50mm deep over weed mat; at that depth one cubic metre covers roughly 20 m².

Why choose it
Good jobs for it
If you are wondering which pebbles to use on a garden path, these smooth, naturally rounded stones are the answer. At 20mm they give stable footing and are still easy and pleasant to walk on, even barefoot. Larger stones can feel uneven underfoot and tiny pebbles move around too much; 20mm River Stone sits right between stability and comfort.
Flowing water has shaped and smoothed these stones over time, leaving beautiful natural colours. Every stone carries its own earthy tones, from warm browns and soft yellows to reds, whites and soft greys. They look good wet or dry, so your outdoor space looks great all year.
Yes. The rounded pebbles give a steady footing and feel good underfoot, even without shoes. Spread about 50mm deep over a compacted base and weed mat, and use edging to keep the stone where it belongs.
At 50mm deep, one cubic metre covers about 20 m². Work out length × width × depth in metres for your cubic metres, or let our volume calculator do it.
It works for lighter vehicle traffic and parking areas. Lay it over compacted road base with solid edging so tyres don’t push the stone around.
It comes unwashed. The fine dust washes off with the first rain or a quick hose, and the natural colours show through.
