High-end luxury bath hardware can be a challenging category. Success or failure depends upon the overall quality of the product.

Concentrating on the material, finish, aesthetics is crucial. However, the aesthetic challenge must be adequately balanced by the manufacturing quality, installation strategy, and needs of the end user.


Design Management

Brainstorming & Ideation

In the scope of a luxury, yet functional hardware design project, we proliferate concepts in an effort to create 're-contextualized' solutions to known and unknown user needs.

Prototyping & Testing

We continuously 3D print drafts of developing design architectures, assessing them as 'sketch models' to rapidly inform the fit, assembly, aesthetic, and scale.

While the product development process can be customized to apply effectively to the needs of the customer and adapt to changing business objectives, Principal Design's 5 step process is a framework that guides the design team and encourages communication and stable execution.

design process


Principal Design approaches every project methodically. The success of a product development project depends upon the clarity and strength of the process. Organized into the five stages most proven to leverage our design efforts, Principal Design's purpose-driven frameworks were developed and refined to reduce risk while balancing exploration with execution. Our creative strategy is divergent to leverage resources and discovery, and convergent to select for the best opportunities.
