If you’ve ever soaked in a cast iron tub, you know: It’s not just a bath—it’s a whole ritual. The water stays warm forever. The surface feels impossibly smooth. The whole set-up is basically crying out for a eucalyptus bundle and a glass of wine.

So it makes perfect sense that Martha Stewart—our eternal queen of making everything feel 15 percent fancier—just signed on as Kohler’s official Cast Iron Ambassador. (Yes, that’s a real title, and yes, we want it on our business cards.) Stewart has long been a fan of the material—enameled cast iron is timeless, durable, and, frankly, the definition of chic. She calls it “beautiful, strong, and long-lasting.” And who are we to argue with Martha? Nobody, that’s who.

Thinking about upgrading your own soak situation? We’re rounding up some of our favorite cast iron tubs from past Domino stories. Prepare to want all of them.

To dodge the dreaded all-white-and-no-soul bathroom reno, designer Leanne Kilroy went old-school—with a massive cast-iron tub she scored on eBay like a true treasure hunter. She refinished it herself (Zinsser BIN primer, two coats of satin paint—DIY queen energy) and splurged on a new floor-mounted filler when the original taps finally waved the white flag. Worth it? “We’ve taken more baths in the past few months than in the past few years,” she says.

When there’s no room for a proper en suite, why not just put the tub in the bedroom? That’s exactly what designer Beth Dadswell did in this 900-square-foot Cotswolds cottage, tucking a freestanding soak spot under the eaves, just steps from the bed. With original beams overhead and moody paint all around, it feels less like a space-saving hack and more like the coziest boutique hotel you’ve ever wept over on Instagram.

For Leanne Ford, white is the ultimate canvas for showing off organic and textural elements—in the case of this 1945 farmhouse, that meant things like ceramic tile, shiplap boards, and a cast-iron tub. To ensure the monochromatic space didn’t read as “meh,” she used an actual sail (yes, from a boat!) for the shower curtain. Because of course she did.

Sibella Court’s claw-foot tub isn’t just for soaking—it’s the main character, the leading lady, the star of the show. Golden wall tile by Sibella Court for Teranova sets a sun-drenched tone, while a vintage claw-foot tub from Antique Baths Sydney brings the undeniable charm. The marble mosaic floors add a cool counterpoint, because even main characters need a strong supporting cast.
