Good morning! The fireballs are available in a number of sizes including 650mm (from £949), 800mm (from £1449), 900mm (from £1499), 1200mm (from £3750), and 1400mm (from £4500). There are a number of designs already available or you can have something bespoke created to suit your specific tastes. The prices are subject to change depending on the complexity of the design and additional options (eg. heat-resistant paint) but this can all be discussed throughout the design process. I hope that answers your question!
