The details
Dimensions exclude adjustable feet. Installation clearances depend on the model and flue arrangement; these are checked during your home survey.
Finish the fireplace
We supply both shaped and square-edged hearths in a wide selection of materials and finishes to complement your new stove and the overall design of your fireplace.
Dark slate remains our most popular choice, offering a timeless, understated finish that works beautifully with both traditional and contemporary interiors.
For something with a little more texture, we also offer Antique Leather matt black granite. This hard-wearing natural stone has a subtly textured surface, adding depth and character while providing a durable, practical finish.
For clients looking for a lighter appearance, our stone and marble-effect porcelain hearths offer an attractive alternative, bringing the look of natural stone into your home with a clean, contemporary finish.
With shaped and square-edged designs available, we can help you choose a hearth that works in harmony with your stove, chamber and surrounding décor.
Planned around your home
From traditional masonry chimneys to modern twin-wall flue systems, we design and install the right solution for your home, stove and property layout. Every installation is carefully considered to provide a safe, efficient and professional finish, whether the flue runs internally through the property or externally along an outside wall.
