Things You Will Need
- Lime scale remover
- Butyl tape sealant
- Silicone adhesive
- Caulk gun
If you’re thinking about replacing your bathtub, whether due to damage or simply to remodel, you can also consider buying a bathtub liner instead. A bathtub liner is custom made to fit right over your tub.
They can be made of acrylic, plastic, or PVC material and are available in a variety of colors to suit your look. Bathtub liners cost about half of what a new tub will cost, and you can install one yourself given the right tools and instructions.
- Clean the bath rigorously with a lime scale remover. Check for any signs of rot. If you do not remove rot, it will spread throughout a wall that has been covered by a liner.
- Place butyl tape sealant and silicone adhesive in the tub according to the liner instructions. Follow the manufacturer’s guidelines carefully. Set the liner into place over the tub.
- Insert caulk into the caulk gun and seal all around the liner edges. This step will seal out moisture.
- Insert drain and overflow cover fixtures that come with the bathtub liner. These should line up with the holes in the original tub. Do not use the liner for a day in order to let the seal bond.
Follow the bathtub liner instructions carefully. A liner that is not fitted properly may give way under enough pressure.
Lime scale remover is toxic. Keep windows open during use.
