Cleaning an Old Cast-Iron Tub? Use a Tub-Liner.

We have a cast-iron bathtub from about 1948. I cannot keep it looking clean anymore. We heard about tub lining. Is that good? We installed ceramic tile around the tub.


A modern tub liner is a great way to repair a worn cast-iron tub. The liners are a thick acrylic or vinyl that is very durable. They are made in many shapes and sizes to fit all the popular tub sizes. You do need a contractor to measure the tub for the proper fit.

Part of the installation is disconnecting and reconnecting the drain line – this takes some experience. Most folks also update the water control valves and shower assembly. Part of the installation often includes replacing the walls with match panels.

Since you have already done ceramic tile around the tub, you will want to review the options for matching the tub to the tile. You don’t want any water behind the walls or under the liner. Once they are installed, they are very durable and look great. Liners can often be installed in one day, so you only lose use of your tub for 24 hours.
