InSinkErator and Sundberg-Ferar have a long-standing business relationship of setting trends for food waste disposers. Multiple generations of Badger models prepared SF for the redesign of the Evolution series of disposers which were aimed at making the units look and sound as durable as they really were. Earlier Evo models had a simple snap-together construction, and with continuous use, occasionally the outer covering or “shells” would disassemble themselves. SF set out to create a new look for these models which allowed for fasteners to be used and highlighted in some cases.

While many directions were explored for the new disposers, ultimately a simple cylindrical form was determined to be the best for the product because of the function, the compact nature, and the existing strong brand identity.

Within this cylinder, proportions of the upper and lower sections were carefully sculpted to convey shapes and lines that communicated strength, and details around the upper neck and outlet are shaped to convey the absorption of vibration. The thickness of stainless-steel bands with the InSinkErator branding and model name were carefully created and surfacing around them sculpted. The fasteners presented new opportunities for design and function, and indentations and coves were created to add strength to the shells and provide access to the fasteners.

Color selection was another key point which took in factors considering the outlets through which the units are sold- generally through big-box stores, or by professional plumbing contractors. The colors of the units reflected these locations, and a Red, a Blue and a charcoal were selected specifically to reflect these avenues of purchase, and to appeal to those specific customers.

Business Impact

InSinkErator produces over 20,000 units per day making the Evolution series of disposers some of the most prolific of any Sundberg-Ferar product design, and one of the most impactful design investments for InSinkErator. These units are found in nearly every new construction build in the USA, and in every case, they communicate the durability, trustworthiness and thoughtfulness of the InSinkErator brand.
