Low-Profile Grandeur, Extended for Larger Spaces
The Oversized Rococo II 20" Cast Iron Radiator takes our most compact decorative model and scales it up in length—making it perfect for long under-window runs, wide feature walls, and larger rooms where traditional styling and strong heat output go hand in hand. With its flowing curves and delicate Victorian detailing, this radiator adds a rich sense of period character to both classic and contemporary interiors.
Hand-finished to order, each oversized radiator is tailored to your exact specifications. Choose from a wide range of painted colors, metallic finishes, or our popular hand-polished and highlight-polished options to complement your space.
To ensure safe delivery and easy installation, oversized models are supplied in two or more parts, complete with joining threads, gaskets, a radiator assembly tool, and step-by-step instructions for straightforward on-site reassembly. Fully pressure-tested to 8 bar, manufactured to meet international standards, and backed by a 25-year guarantee, the oversized Rococo II 20" heritage radiator offers the perfect balance of decorative elegance and durable performance.

Hand Polished Cast Iron Radiators

Hand polishing cast iron radiators is a very time consuming process. Each section is individually polished with a series of bespoke polishing wheels.
We only polish the visible areas - the front, the top and on the end sections but not on the back which would be placed against the wall.
