Design 16 cleaning brushes

I’m putting together a cohesive product line of sixteen all-purpose cleaning brushes aimed squarely at bathroom care—everything from toilets to sinks and faucets right through to the shower and bathtub surfaces. I need each brush to share a common design language yet be purpose-built for its specific task, so the set feels like a family on the retail shelf and in the customer’s hand.

What I’m after
• Sixteen individual brush concepts, each visually rendered and dimensioned so a manufacturer can quote and prototype without guesswork.
• Attention to user comfort, intuitive grip and straightforward manufacturability; injection-molded handles with over-molded soft touch zones are perfectly acceptable, but I’m open to alternatives if you have stronger ideas.
• Thoughtful bristle selection (shape, density, material) tailored to the three target areas listed above.
• Files delivered as high-resolution presentation visuals (PDF or JPG) plus editable 3D (STEP or similar) ready for hand-off to an engineering team.

How we’ll work
I’ll share brand guidelines and existing packaging templates once we kick off. We’ll agree on a mood board, then move through quick thumbnail sketches, refined CAD, and final production-ready outputs, checking alignment at each stage so feedback is tight and the schedule stays on track.

If you’ve developed consumer cleaning tools before—or generally excel at ergonomic, injection-mold friendly products—let’s talk. Please include relevant portfolio examples and note any materials or production constraints you think we should consider upfront.
