Slate is one of the best natural floors you can lay — dense, slip-resistant and forgiving of the knocks a busy floor takes. But “floor tile” covers a lot of ground, and not every slate on sale is cut for the job. This page is the floor-buyer’s route into slate tiles: what actually makes a slate floor-grade, then live per-square-metre prices from 10 UK retailers as each colour comes online.

Each colour opens its own live comparison — size selector, postcode delivery costing and the day’s prices from every retailer that stocks it. Black is first up. Looking for the full range? Head back to slate tiles.
Four things decide whether a slate belongs on a floor. Get these right and the price comparison becomes a like-for-like fight; get them wrong and a cheap tile can cost you twice.
Floors want body. 10mm is the workhorse thickness for slate floor tiles — enough to take furniture, footfall and the odd dropped pan without cracking. Thinner riven pieces suit walls, not floors.
A calibrated tile is ground to an even thickness on the back, so it beds flat and level. Uncalibrated slate varies tile to tile, which turns a floor into a lippage nightmare. For floors, calibrated is worth paying for.
Riven grips and hides wear — ideal for halls and kitchens. Honed is smooth and calm but shows more, better suited to lower-traffic rooms. The finish is really a decision about how much traffic the floor takes.
Slate is a natural conductor, so it warms quickly and holds heat well over underfloor heating — one of the reasons it’s a favourite for conservatories and open-plan floors. Just bed it on a flexible adhesive rated for movement.
Riven, honed or brushed changes how a slate floor grips, wears and prices. Our plain-English guide walks through all three, starting from the room rather than the look.
