The Cast Tec Athena Granite Fireplace offers a refined balance between contemporary styling and timeless material choice. Formed from polished black granite, this hearth-mounted mantel is defined by its clean lines and distinctive handcrafted corbels, creating a focal point that feels substantial without appearing heavy.
As part of the Cast Tec Collection, the Athena is designed to integrate with the brand’s innovative Integra cast inserts, allowing you to tailor the fireplace to your preferred fuel type and heating performance. Whether you are renovating a living room or designing a new interior scheme, it provides flexibility without compromising on visual impact.
Design, Materials & Visual Impact
Polished black granite delivers a sleek, reflective finish that enhances both natural and artificial light within a room. The deep tone contrasts beautifully with lighter walls while complementing darker interior palettes, making it suitable for a wide range of décor styles.
The defining feature of the Athena mantel is its pair of hand-crafted corbels. Unlike overly ornate traditional surrounds, these corbels introduce subtle sculptural detail while retaining a modern aesthetic. The overall silhouette remains simple and architectural, allowing the fireplace to act as a sophisticated centrepiece.
When combined with a matching black granite hearth, the result is a cohesive installation that feels deliberate and premium. The optional Viscount Integra arched insert, as shown in imagery, demonstrates how the Athena can be styled with decorative cast inserts for added character.
Heat Output, Efficiency & Fire Options
The Athena mantel itself is a decorative surround and can be paired with a wide selection of Integra fire options. This flexibility allows homeowners to select the level of heat performance that best suits their property.
Options include high-performance gas fires, realistic electric fires or solid fuel boxes for burning wood or approved smokeless fuels. This adaptability makes the Athena suitable for homes with chimneys as well as properties where electric installation may be more practical.
When specified with the Integra Electric Fire, users benefit from a flame-only mode for visual ambience alongside a 1.5kW heat setting to provide additional warmth when required.
Controls & User Experience
The Integra Electric Fire option is operated via remote control for convenient adjustment of flame effects and heat output. Manual controls are also located on the unit, offering straightforward operation when needed.
This blend of traditional fireplace styling with modern control systems ensures the Athena can deliver atmosphere throughout the year while remaining easy to manage on a day-to-day basis.
Installation Requirements & Dimensions
The Athena mantel is designed for hearth-mounted installation and is available in two top shelf lengths to suit different chimney breast widths:
- 1500mm shelf length (approx. 59″)
- 1350mm shelf length (approx. 53″)
The 1500mm model will comfortably accommodate a hearth measuring approximately 1450mm x 430mm. This makes it suitable for standard-sized fireplace openings while also offering a scaled option for more compact spaces.
When paired with the Integra Electric Fire and a surround featuring a 3-inch rebate, installation can be completed flat against a wall without requiring additional recess depth.
