Slate Hearth - The Go-to Option

Slate hearths are by far and away the most well known option. When a customer speaks to use about getting their bespoke fireplace hearth made, it is always slate that they ask for first. And it's easy to see why.

Slate is aesthetically pleasing with plenty of natural variation for a decorative and interesting surface. 

However, they are a more expensive option than some other materials and often the alternative materials will be just as suitable, if not more suitable than a slate piece.

Pros of Slate

- Naturally smooth so suited to a burner.
- Warm tones add to the heating effect of the space.

Cons of Slate

- Premium material so costs extra.
- Natural variation means each piece is unpredictable.
- Limited choice of edge finishes.

Alternatives: Black Limestone or Granite


Black Limestone Hearth - The Most Popular

Not many people know Black Limestone exists as an option which is nicely illustrated by the search figures above. But once they learn about the material, a surprising amount of people opt for it as an alternative.

The colour is consistent. There is almost no variation across the surface, so you know exactly what you are getting from piece to piece. 

On top of this, the surface is still naturally smooth and perfectly suited for a burner.

Pros of Limestone

- Consistent colour and surface finish.
- Deepest black colour available.
- Very budget friendly.
- Easily worked, so lots of options for your fireplace hearth edges.

Cons of Limestone

- No natural variation so will look just like any other limestone hearth.
- More likely to fade than slate.




Granite Hearth - The Toughest

Granite is one of the options that people are frequently searching for. It's an incredibly hard stone and ages really well through the years. Because of it's geological makeup, granite is incredibly tough and resistant to damage.

Ash Granite hearth The tough nature of granite means it's very resistant to scratches, damages and stains of all variety. If you are using a working burner with pokers and tools, granite may well be a great option for you thanks to it's hardy nature.

There is also a slightly varied surface texture and pattern thanks to the cooling of volcanic rock that forms the granite material. 

The surface is still overall nice and smooth, but it has a dimpled effect so isn't quite as smooth as other options.

However, due to the fact the stone is so tough it does require more work to cut, so it is the most expensive option.

Pros of Granite

- Incredibly tough. More scratch and stain resistant than the other options.
- Decorative surface thanks to the way is formed.

Cons of Granite

- Most expensive option.
- Unpredictable surface.


Grey Sandstone Hearth - The Most Natural

This is a slightly less considered option, but that's not to say it should be written off altogether. Grey sandstone is great for those looking to create the most natural, traditional look as it maintains quite a lot of the characteristics that are common in traditional natural stone.

Unlike most of our other options, this stone is not designed to give a smooth, contemporary effect but to complement a traditional property and a rustic fireplace. The surface of the stone is rough, but we still only  select pieces suitable for log burners, so they won’t be too uneven to use.

 Pros of Sandstone

- Natural look.
- Resistant to scratch and fade.
- Well suited to traditional properties.
