Martha Stewart and Kohler just made the most unexpected bathroom essential feel luxe – she's reimaged cast iron for good

Martha Stewart is practically synonymous with home improvement, so it makes sense that her latest business venture is with one of the most renowned heritage home brands.

The interiors expert is Kohler's new ambassador (the first role of its kind), representing the nearly 150-year-old brand's cast iron collection.

'It’s such a pleasure to partner with the innovative minds at Kohler to bring awareness to the variety and depth of their enameled cast iron offerings,' Martha says.

'I have been a proponent of enameled cast iron for decades, all throughout the home, and look forward to sharing my passion for the material with the world, and helping others discover its beauty, strength, and lasting value – especially through the lens of the category leader, Kohler.'

'Martha Stewart personifies quality, design, and what it means to live a gracious lifestyle – making her the perfect partner to help us celebrate the extraordinary character of Kohler Cast Iron,' continues David Kohler, the chair and CEO.

Kohler is a brand with a rich history: it started back in 1883 by John Michael Kohler, who transformed a cast iron horse trough into the brand's first enameled bath. Since then, their collection has expanded into shower bases, bathroom sinks, and kitchen sinks; all the essentials for a functional and aesthetically pleasing home.

Sustainability and style are at the core of Kohler's cast iron range, with materials made of at least 80% recycled material. Meanwhile, their designs range from contemporary to traditional (think clawfoot tubs and farmhouse sinks).

Additionally, the pieces are all handcrafted and backed by Kohler’s Limited Lifetime Warranty, which means they resist chipping, cracking, and burns, making them worthwhile investments for the home.

As a part of the partnership, Martha will headline the Kohler Food & Wine Festival, taking place in Kohler, Wisconsin, from Thursday, October 16th to Sunday, October 19th, 2025. Until then, you can shop the cast iron range from Kohler on their website. Your bathroom will surely thank you for following suit.
