This Clerkenwell Design Week 2026, C.P. Hart is pleased to partner with premium Argentinian brassware makers Franz Viegener for a showcase of the latest in bathroom design.

On display, discover Franz Viegener’s Classic and Zephyr brassware, where intricate grooved detailing merges Art Deco styling with contemporary aesthetics. Also revealed is our new Slide tap collection - a true innovation in bathroom ergonomics, with tap handles crafted from gold and diamonds.

At the basin, our Monroe collaboration with British makers Kast demonstrates the power - and beauty - of hand-poured concrete, exhibited in the signature and trending Crimson colourway for optimum warmth and impact. In addition, our exclusive London Cloakroom basin is a triumph in small bathroom design, emblazoned with C.P. Hart’s founding year, 1937, and available in seven joyful colourways for adding cloakroom character in abundance.
