A cast iron bathtub is one of the best candidates for restoration. The shell is heavy, rigid and durable, so when the main problem is old enamel, restoration is often smarter than full replacement.
Why cast iron restores well
- Rigid structure. The shell barely flexes under load.
- Thick metal body. It tolerates surface preparation better.
- Many older tubs are better made than cheap modern ones.
- Replacement is too labor-heavy. Weight and removal make restoration logical.
Most common methods
- Enameling.
- Liquid acrylic.
- Local chip repair plus full finishing.
What to check before work
- Deep rusted chips.
- Leaks at the waste assembly.
- Failed wall joints and old sealing.
- Enough access for proper preparation and masking.
Typical cost
- Cast iron bath restoration — from 430 ₪
- With difficult prep or deep corrosion — higher depending on condition
Frequently asked
Is an old cast iron tub worth keeping?
Very often yes. If the shell is sound and the problem is the finish, old cast iron is often stronger and better than low-end new tubs.
Is cast iron better for enamel or liquid acrylic?
Both are possible. The choice depends on the surface condition, budget and the finish thickness and durability you want.
Why not just replace a cast iron tub?
Because removal and carrying are usually much heavier, noisier and more expensive than restoring the surface.
