The Riva F40 Cube is one of the most exciting additions to Stovax’s freestanding range. Based on the highly successful Riva 40 inset fire, the F40 brings all of that proven firebox technology into a compact stove format. With its clean cube design and stylish finishes, it offers a fresh alternative for those who want the performance of the Riva range but prefer a freestanding installation.
The first thing you notice about the Riva F40 Cube is its distinctive look. With a choice of Storm or Jet Black Metallic paint finishes, this is a stove that stands out from the crowd. The bold Storm silver option is particularly eye-catching and makes a striking contrast to the more traditional black stove designs on the market.
Flexibility in installation is another highlight. The F40 can be hearth-mounted in the classic way, or paired with one of ten Riva Benches, offering a variety of heights and styles to suit different interiors. Its compact footprint and stylish cube form mean it works equally well in contemporary living rooms and more traditional spaces.
The Riva F40 Cube has been designed with installation flexibility in mind. It offers both top and rear flue exits, each with a 128mm (5″) internal diameter, giving installers options depending on the room layout. At 82kg, it’s a solidly built appliance that feels substantial without being unmanageable.
Whether you choose to hearth-mount or place it on a bench, the F40 Cube gives you the freedom to create a focal point that suits your home. The large glass window, combined with the Airwash system, ensures the fire remains the star of the show.

Behind the sharp exterior, the Riva F40 Cube is packed with features designed to make everyday use simple and efficient. The stove delivers a nominal heat output of 4.9kW, with a wide range from 1.7kW to 7kW, making it ideal for medium-sized rooms. With an efficiency rating of up to 81% and an A-class energy rating, it offers excellent performance while helping you get the most from every log.
This is a true multifuel stove, with Stovax’s Opti-Burn setting optimising combustion whether you’re burning wood or solid fuel. The externally operated riddling system, accessed via the dedicated ashpit door, makes it easy to switch between fuels and maintain the fire. Logs up to 250mm (9¾”) can be accommodated with ease, while the Airwash system keeps the glass window clear, ensuring you always get a great view of the flames.
Like all stoves in the Riva range, the F40 benefits from Stovax’s Cleanburn technology, delivering more heat into the room and reducing emissions. For those in Smoke Control Areas, the F40 can be fitted with an optional Smoke Control Kit to make it DEFRA exempt.
The Riva F40 Cube is more than just a compact stove — it’s a statement piece. Its bold finishes, modern lines, and high efficiency make it one of the most appealing freestanding stoves currently available from a UK manufacturer. It brings the trusted performance of the Riva inset range into a new format, offering style, flexibility, and impressive heating power in one neat package.
With a recommended retail price of around £1695, the F40 Cube sits in the premium segment of the market, but for those looking for a stove that combines contemporary design with cutting-edge combustion technology, it represents strong value. For homeowners who want something more than just another black box stove, the F40 Cube is a compelling choice.
Stylish, efficient, and versatile, the Riva F40 Cube is one of the standout stoves of the year. It combines the advanced firebox technology of the Riva 40 inset with a striking freestanding design, available in bold finishes and adaptable for different room styles.
Whether you’re burning wood or solid fuel, living in a Smoke Control Area or not, the Riva F40 Cube has the performance and looks to make it a lasting feature in your home.
