C1 STS Core Kit – 2.5m Straight Run Outdoor Kitchen Frame

The Sumo Core™ C1 STS Kit is a pre-engineered, 2.5m straight-run outdoor kitchen frame, designed to give you Pro-level strength with plug-and-play simplicity.

Built using our 50mm galvanised steel Core system, this modular kit arrives flat-packed with all the cut-outs and configurations you need to quickly assemble your dream setup using just an Allen key.

Once assembled, simply level the frame and sub-clad with 9–12mm construction board – such as STS, Magply, or other high-quality fibre cement or cement board panels. Just cut to size, screw directly to the frame, and you’re ready to start tiling, rendering, painting, or finishing however you like.

Comes with a complete instruction pack and finishing guide to walk you through every step – from assembly to cladding.
