Designing a Freestanding Concrete Bathtub for Repeatable Manufacture
Minimal aesthetic, compound curvature.
Raw Concrete Design needed a freestanding concrete bathtub that felt minimal, sculptural, and refined, while still being practical enough to manufacture repeatedly. The challenge was to create a clean form with soft compound curvature, correct internal volume, and enough design detail to feel considered without becoming overly complex.
As the freelance Industrial Designer, I developed the bath form in Fusion 360, working closely with Raw Concrete Design to understand the material behaviour and production requirements of concrete. The design process also included a deep dive into fibreglass production methods, helping translate a visually simple product into a repeatable manufacturing approach.
The final design balanced minimal aesthetics with careful surface development, using asymmetric fillets, compound curvature, seamless transitions, and a subtle offset detail at one end. The result was a freestanding concrete bath that could move from concept into production with a clear manufacturing method behind it.
