My cast iron enamelled bath is dull, rough, stained or scratched - can it be restored?

If your bath is made of cast iron, yes it can. A specialist operation can be carried out involving grinding away the damaged surface and then polishing the enamel to restore the original shine and colour. This process is most successful on white, pastel and light colours. The stronger colours such as burgundy, dark blue and dark brown will not re-polish successfully. Even if you have minor chips in the enamel, these can be patched using a specialist colour matched filler.

(NOTE – this filler is NOT vitreous enamel). See Repolisher details


Where and how can I get my cast iron bath re-enamelled or are there any other options?

There are two options if your bath is just worn. The enamel feels rough to the touch - this tends to occur in the base of the bath. You can have it re-polished. This can be done in situ and is a specialist operation:

OR You can have it re-enamelled. For this it must be removed and transported to a specialist re- enameller: See Re-enamellers 

If your bath is badly chipped or you would like to change the colour, the only option which is available to you is to remove the bath and send it to a specialist company who will carry out the re-enamelling of your bath with genuine vitreous enamel: See Re-enamellers

Please be aware that there are many companies advertising and offering re-enamelling in-situ. This is not genuine vitreous enamel - it is a type of paint. The more reputable companies carrying out this service will describe it as "bath re-surfacing". It is a shorter-term solution, but cannot be as hard or durable as genuine vitreous enamel. These companies may also be able to carry out a cosmetic repair of chips. Genuine Vitreous Enamel is a type of glass, which is fused at high temperatures to achieve its unique combination of hardness and durability, which is unmatched by other finishes.

Re-enamelling will involve shot blasting to remove the existing enamel, followed by specialist welding if there is any damage or heavy rusting, for example around the plug hole. It will then be coated with up to three layers of vitreous enamel. Each layer will be fused to the surface by heating in a furnace to a temperature above 750 degrees Centigrade. It is this genuine vitreous enamel finish which will give the durability and long life that your bath has given you until now.


Can I repair a chip on a piece of enamel?

It is not possible to carry out a repair to vitreous enamel, except by specialists in the re-enamelling of already enamelled parts. Repair kits are available from the major do-it-yourself outlets, but these are only a paint which can never be as hard and durable as the original vitreous enamel. They will not withstand arduous use or the high temperatures which will be found in an appliance oven, grill or hotplate. However, they will often give a short term cosmetic repair in other areas, which may satisfy your needs.

Companies who carry out bath polishing will also provide this type of chip repair Click Bath Polishing

If you wish to have the part re-enamelled please contact one of the specialist vitreous enamelling companies listed in our Bath Re-enamellers; Cast iron Re-enamellers; or Steel Enamellers

Where can I buy some enamel?

If you are thinking that you will be able to re-enamel your bath or cooker then simply it isn’t possible. The application of vitreous enamel requires specialist equipment and must be fused at a temperature above 750 degrees Centigrade. Normal ‘industrial’ size industrial enamelling is thus outside the scope of home application. However, if you wish to try your hand at some DIY enamelling for copper jewellery there are some very simple kits available from craft shops or from W. G. Ball Ltd, Stoke on Trent.
