From your worktop offcut
A set cut from the leftover of your own worktop, so it matches the kitchen exactly. Say so when you ask for the worktop quote, because the offcut has to be set aside before it is broken down or returned to stock.
Stone coasters cut to size, in quartz, granite and sintered stone

Stone coasters cut from the same stone as your kitchen, often from the offcut of your own worktop, or from any quartz, granite or sintered stone in our range. Square or round, every edge polished and eased, and priced as a set on the quote. For homes, and for bars and restaurants that want coasters to match the stone they serve on.
A coaster is the smallest piece of stone that has to be finished properly
A coaster is a small square or round of stone that spends its life under wet glasses, hot mugs and bottles of wine. It is handled every day, picked up by its edge and put down on a table that is usually softer than it is. So the work is not in the size of the piece. It is in the edges, the face and what sits underneath.
The best reason to have stone coasters made, rather than buying a set, is that they can be cut from the stone already in your kitchen. A worktop job leaves an offcut, and a piece too small for anything else is often enough for a set. The colour and the pattern then match your worktop, because they are the same slab.
That only works if you ask before the job. Once the offcut has gone back into the racks or been broken down, it is gone, and the set is cut from whatever stone is chosen instead.
Cut and finished in our own workshop. The timing, and how the piece reaches you, are set out on your quote.

Which set
Coasters for a kitchen, a table and a bar
The same small piece of stone, asked to do slightly different things.
In a colour from our range
No worktop job needed: a set in any quartz, granite or sintered stone we hold. Every colour has its own page in the colour library, with what the stone is like to live with.
Square coasters
Cut on the saw, with the edges polished and every corner eased. The simplest shape to make and the easiest to stack, and the one that suits a stone with a strong straight vein.
Round coasters
Cut on the CNC from a drawing, which is what makes every round in a set the same size and true all the way round. A circle cut by hand is fair in places and flat in others, and side by side that shows.
For bars and restaurants
A set that matches the stone a business already serves on: the same colour as a bar top or a set of stone table tops. Ordered with the larger pieces, they come from the same batch or slab.
As a gift
A set cut from the stone of a kitchen someone has just had fitted, or in a stone they would never have for a whole worktop. Small enough to be a modest piece of stone, finished as carefully as the worktop.
What is involved
From an offcut to a finished set
Small pieces, the same workshop and the same finishing as a worktop.
- At quotation
Choose the stone, or keep your offcut
If you are having worktops made, say at the quotation stage that you want the offcut kept for coasters. If not, choose a colour from the range. Either way, the stone is settled before anything is cut.
- At quotation
Settle the size, shape and number
Square or round, how big and how many. A set is cut in one go from one piece of stone, so a coaster added later may come from different stone and read differently from the rest.
- Before cutting
Choose the finish
Polished or honed, and whether you want anything underneath to protect the table. Ask at quotation and we will say what the workshop can do for that stone.
- Workshop
Cut and polish
Each piece is cut, the edges polished and the arrises eased so a coaster picked up a thousand times does not chip at the corner. Round ones are machined on the CNC.
- Last
With the worktop, or as the quote says
A set cut from a worktop offcut can come with the worktop on fitting day. Otherwise how the set reaches you is agreed on the quote.
The parts that decide it
What a stone coaster has to cope with
Each stone behaves differently under a wet glass, a hot mug and a spilt glass of wine.
Quartz: no sealing, but mind the teapot
Quartz is non-porous, so condensation, coffee and wine wipe off without soaking in. It is made with resin, which is why a pan straight from the hob wants a trivet on a quartz worktop. A mug of tea is fine. A teapot or a cafetiere straight off the boil is a better job for granite or sintered stone.
Granite: sealed, because it is porous
Granite takes heat well, which suits a coaster under hot drinks. It is natural stone and porous, so it is sealed before use and resealed from time to time. Unsealed, a ring of red wine or a slice of lemon left on it can leave a mark.
Sintered stone: heat and stains
Sintered stone is fired at high temperature with no resin in it, so a hot pot and a spill of wine or citrus are both its kind of job, with no sealing. It is hard and brittle at a sharp corner, which is one more reason the arrises are eased.
Polished or honed
A polished coaster shows the colour and pattern at their richest, and it also shows the faint ring a wet glass leaves until it is wiped. A honed face hides water marks better and feels softer in the hand. It is a choice about how the set looks after a long evening, not about how long it lasts.
The table underneath
Stone is harder than most table finishes, so a bare coaster slid across a wooden or lacquered table can scratch it. A backing on the underside protects the table and stops the coaster rattling on glass. Ask at quotation what the workshop can fit for your set.
Thickness and weight
A thicker coaster feels more substantial and does not tip when a glass is put down on its edge. It is also heavier, and a stack of them is real weight. We will say what thickness your stone comes in and what suits a coaster.
Why the offcut has to be asked for early
An offcut is the part of the slab left after your worktops are cut. It is easy to keep when the job is being planned and impossible once it has gone back into the racks or been broken down for disposal. If you want coasters, a chopping board or a shelf from your own worktop, say so when you ask for the worktop quote, and it will be set aside.
Before you order
What to decide, and what is not included
A set of coasters is a small order, and every decision on it is quick. They are best made once.
Have this decided
- The stone: your own worktop offcut, or a colour from the range
- Square or round, and the size of each piece
- How many are in the set, decided together
- Polished or honed
- What the coasters will sit on, so the underside suits the table
- Whether they are for a home, or a bar or restaurant with matching stone
What we do not promise
- An offcut that has already gone back into stock or been broken down
- An exact match on a coaster added to a set later
- A match to a worktop fitted by someone else, from a different batch
- Anything beyond cutting and finishing stone that the workshop has not confirmed on your quote
Questions
Stone coasters: the questions worth asking
If yours is not here, ring and ask. You will get a straight answer rather than a call-back from a salesperson.
01Can you make coasters from my worktop offcut?
Yes, if the offcut is kept. Say so when you ask for your worktop quote, and the piece left after your worktops are cut is set aside for the coasters rather than going back into stock. Cut from the same slab, the set matches your worktop exactly.
02Which stone makes the best coasters?
Sintered stone if the coasters will see hot pots and wine, because it has no resin and needs no sealing. Quartz for everyday glasses and mugs, with no sealing and the widest colour range. Granite takes heat well and suits natural stone tables, but it is porous and needs sealing.
03Can I put a hot mug on a quartz coaster?
A mug of tea or coffee, yes. Quartz is made with resin, so the same caution as on a quartz worktop applies to anything much hotter: a teapot or a cafetiere straight off the boil is better on a granite or sintered stone coaster.
04Will stone coasters scratch my table?
Bare stone can scratch a softer finish if it is slid across it. A backing on the underside stops that and stops the coaster rattling on glass. Ask at quotation and we will say what the workshop can fit for your set.
05Can you make round stone coasters?
Yes. Round coasters are cut on the CNC from a drawing, so every one in a set is the same size and the curve is true all the way round. Square coasters are cut on the saw and polished.
06How much do stone coasters cost?
They are priced as a set on the quote, by the stone, the size, the shape and the number in the set. A set cut from the offcut of a worktop we are already making uses stone that is part of that job.
07Do you make coasters for bars and restaurants?
Yes. A set can match the stone of a bar top or a set of table tops, and ordered with those larger pieces it comes from the same batch or slab. Ordered later, expect a close relative rather than an exact match.

When granite needs sealing, and how to tell
How to tell whether your granite actually needs resealing, why the annual rule everyone repeats is wrong, and how to apply a sealer without leaving a haze you then have to fix.

Stains and etches look alike and need opposite treatments. How to tell them apart, what to do in the first minute, the poultice method properly explained, and what will make it permanently worse.
Read the guideWhat sintered stone actually is
Sintered stone is a worktop slab made by pressing mineral powders under very high pressure and firing them until they fuse into one dense body, with no resin binding it. That is why nothing in it can scorch, it never needs sealing and it can be made thin.
