From Sheet to Soak: How Brass Bathtubs Are Crafted by Hand

Brass bathtubs aren’t factory-line products. They’re made the old-school way—by hand, from raw metal, with serious attention to detail. If you’ve ever wondered what goes into making one, here’s how skilled makers turn flat brass sheets into fully functional luxury tubs.

1. Starting with the Right Metal

It begins with brass—an alloy made from copper and zinc. The mix can vary depending on the tone and strength the maker wants. Once the alloy is chosen, it’s either purchased as large sheets or cast in-house.

2. Forming the Shape

Creating the body of the tub is all about precision. The brass is cut and heated, then shaped using spinning, hammering, or rolling techniques. Depending on the design, a tub might be formed from one continuous piece or assembled from several.

This is where the maker’s skill comes through. The curves, edges, and symmetry all have to be spot-on, especially if it’s a freestanding or sculptural style.

3. Welding the Pieces Together

For multi-piece tubs, welding is next. Brass requires a careful touch—too much heat can damage the finish, too little and the join won’t hold. Once welded, all seams are ground and smoothed until they’re practically invisible.

4. Polishing and Surface Finishing

Polishing brings the tub to life. Makers use sanding, buffing, and sometimes chemical treatments to get the desired finish—whether that’s a high-gloss shine or a softer matte look. Some tubs are sealed with a lacquer to protect the finish; others are left raw to develop a natural patina over time.

5. Interior Coating (Optional)

Not all brass tubs are brass inside. Some are lined with enamel or a composite coating for a warmer touch or easier maintenance. This step depends on the design and the end user’s preference.

6. Final Assembly and Quality Checks

Last comes the hardware—feet, fixtures, and overflow drains. Everything is assembled and tested to make sure it’s level, watertight, and ready to install.

A Brass Tub Is Built to Be Seen—and Last

Brass bathtubs combine utility with style. But the real story is in how they’re made: by hand, by skilled craftspeople, with no shortcuts. That’s what gives each one its weight, both physically and visually.
