Brass bathtubs aren’t just showpieces. They’re functional art—handmade, heavy, and built to last. But how do you go from sheets of metal to a polished, gleaming tub that can weigh over 200 pounds? Here’s a breakdown of how they’re made from scratch.
1. Sourcing the Brass
It starts with the raw material. Brass is an alloy of copper and zinc. The ratio varies depending on the look and strength the maker wants—more copper gives a warmer, reddish tone, while more zinc cools it down. Some manufacturers buy pre-made brass sheets; others melt and cast their own alloy.
2. Shaping the Tub
Shaping a brass bathtub isn’t a matter of pressing a button. It’s done by hand, using a method called metal spinning or hammer forming. Large sheets are cut to size, heated, and slowly bent over molds using manual tools or powered rollers. This is where craftsmanship matters most. The curves have to be perfect—no sharp edges or warps.
For more complex shapes—like clawfoot tubs or double-ended designs—multiple pieces of brass are formed separately and then joined together.
3. Joining and Welding
Once shaped, the parts are welded. This might include the tub body, the base, and any decorative rims or feet. Welding brass is tricky—it needs skill and heat control to avoid discoloration or weak joints. After welding, the seams are ground down smooth. Done right, you won’t see any lines or weld marks at all.
4. Finishing and Polishing
This is where the tub starts to shine—literally. The surface is polished, either to a mirror finish or a softer, brushed look. This can take hours of sanding and buffing. Some tubs are left raw to age naturally and develop a patina. Others get a protective lacquer to keep the shine.
5. Optional: Interior Coating
Some brass tubs are left fully metallic inside. Others are coated with enamel or a resin-based layer for a smoother, warmer surface. This step is optional but adds a different feel and reduces heat loss.
6. Final Touches
Feet, fixtures, and overflow hardware are added last. These are often made of matching brass or complementary metals like bronze or chrome. Everything is tested for balance, seal, and water-tightness.
Brass Tubs Are Built, Not Mass-Produced
Each brass bathtub is a labor of precision and patience. No two are exactly alike, and that’s the point. Whether in a high-end hotel or a home bathroom, a brass tub isn’t just a bath—it’s a statement. And behind every one is a team of metalworkers who know their craft.
