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.

Things You'll Need

  • Lime scale remover
  • Butyl tape sealant
  • Silicone adhesive
  • Caulk
  • Caulk gun

Video of the Day

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.
