2pc Pairs Now Cut To Size Option....
PRODUCT UPDATE – 2pc Pairs
We've decided to offer an alternative to our 2pc pairs with a cut-to-size option.
We originally introduced the 2pc pairs because customers wanted two matching pieces cut from the same slab, ensuring a consistent colour and texture across both halves of the hearth. We later added the 2pc sets — complete with front hearth edge finishing — hoping to phase the pairs out, but we still occasionally get requests for them.
Introduced 2pc Sets
https://hardstuffltd.co.uk/order/standard-2pc-riven-slate-hearth-sets-20mm/
So moving forwards, rather than stocking both options, we'll now offer a cut-to-size alternative: a single slab cut into two matching pieces to suit your requirements. Because both pieces come from the same slab, you still get the matching colour and grain that made the pairs popular.
Example 1
1 x 1200×900 cut to
1200×381 + 1200×516 (less 3mm blade)
Example 2
1 x 1350×900 cut to
1350×457 + 1350×440 (less 3mm blade)
There is a charge for this service of
£12.50 for 1 straight cut per slab + vat
NOW IN STOCK: New Brazilian Riven Slate Shapes
With these latest additions, our Brazilian Riven Slate range will now span nine distinct shapes — giving you more choice than ever to find the perfect fit for any fireplace or installation.
We're excited to announce five new shapes joining the range. Each piece is cut and finished to the same high standard as our existing slate hearths, now in versatile new designs to suit a wider variety of fireplace openings and installations.
New shapes:
Small Arc Square - NOW IN STOCK
Medium Arc Square - NOW IN STOCK
Medium Arc Rectangle - NOW IN STOCK
Circles - Coming Soon
The arc-cut fronts give a softer, more contemporary look, while the circular hearths offer a striking centrepiece option — all retaining the natural riven texture and character Brazilian slate is known for.
