Cast-Iron Bathtub Refinishing in Los Angeles
If your Los Angeles home was built before the 1970s, there’s a good chance the tub is cast iron under a layer of porcelain enamel — heavy, solid and built to outlast the house. The enamel wears out; the iron doesn’t. Refinishing gives that tub a new surface in a single visit, without ever moving it.

Why a cast-iron tub is worth refinishing
A cast-iron tub holds heat, doesn’t flex, doesn’t creak and doesn’t sound like a drum when the water runs. New tubs in that class cost thousands before installation. The ones in LA’s older bungalows, Spanish-style houses and 1920s–60s apartment buildings are the same quality — they’ve just lost their glaze.
What usually goes wrong is only the surface: the porcelain gets dull and porous, picks up stains, chips around the drain and the rim, and rust shows where the iron is exposed. All of that is fixed by refinishing. None of it is fixed by scrubbing harder.
What replacing a cast-iron tub actually involves
Replacement
- Demolition — tile and often part of the wall come out to free the tub; the floor around it usually needs work too.
- Getting it out — 300+ lb of iron down a hallway or a flight of stairs; many are broken up with a sledgehammer right in the bathroom.
- Plumbing — drain and overflow disconnected and redone for the new tub; faucet often replaced.
- A week or more without a bathroom, plus the cost of a new tub, a plumber, a tile setter and disposal.
Refinishing
- Nothing moves — the tub, tile, faucet and drain stay exactly where they are.
- One visit, 3–4 hours — sanding, acid etching, cleaning, sealing the seam, pouring the enamel.
- Ready in 24 hours — fully cured, glossy white, with a 5-year warranty.
- A fraction of the replacement cost — and you keep the better tub.

Refinishing cast iron with the pour-on method
Cast iron is the best possible base for pour-on enamel: rigid, heavy and cool, so the enamel levels slowly and evenly and bonds to a surface that will never flex underneath it. Our process is built around that.
- Sanding. The old glaze, stains, lime scale and surface rust are ground down with abrasives. Chips and rust pits are opened up so they can be filled properly.
- Acid etching and neutralizing. The porcelain is etched, rinsed, scrubbed with a soda-based cleaner and rinsed again — this is what makes the new coating grip.
- Drying, sealing, masking. The tub is dried with heat and wiped with alcohol; the tub-to-wall seam is resealed, chips are filled, fixtures and tile are masked.
- Pouring. The enamel is poured around the rim and flows down the walls into one seamless, glossy layer — no spray, no brush marks. If the tub has an apron (the front panel), it’s coated too.
Hold a magnet to the side: if it sticks, the tub is cast iron or steel and we can refinish it. Or just send us a photo — we’ll tell you.
