Double the capacity of your Wooden 905 Litre Compost Bin with our extension module.

By using the poles on the side of your existing compost bin and sliding in the new panels, you can double or even triple the size of your bin in no time.

Made from FSC Certified white wood, this item has come from a sustainably managed forest and supply chain. The 18mm thick wood provides insulation to the compost bin, whilst also providing porous properties.

All the wooden boards and posts are hand dipped in a non-toxic wood protection (they are not pressure treated/tanalised). It is recommended that you re-treat once every two years with a similar product or preservative when the wood is dry, you can prolong the life of your compost bins further by turning over the posts and rotating/reversing the boards to even out wear and tear. As with all wooden products kept outside, colour can vary and change over time.

Please note, this is not a full compost bin; an existing Wooden 905 Litre Modular Compost Bin is required. Photograph shows both units. Lid not included.
