How to Recaulk a Bathtub

Dirty, cracked or stained caulking around the bathrub is just about one of the ugliest things your bathrooms can throw at you. Other than just being hard to look at it, cracked, moldy or failing caulk can also allow water to seep between the tub wall and the tub itself which can led to a whole new set of issues. That’s why you want to re-caulk the tub soon after you see that it is damaged or failing.

Many homeowners seek tile or bathroom repairman to fix this issue, but with a little knowledge and just a few supplies homeowners can replace the caulking around their bathtub with ease. Here is how to re-caulk a bathtub.

How to Recaulk a Bathtub

What You Need

  • Utility knife
  • Caulk remover tool or Caulk multi-tool
  • Putty knife
  • Bathroom tile cleaner
  • Bathroom tile caulk

Now that you have all of your supplies handy, you can likely finish the job in less than an hour with these steps:

  • Use the caulk remover tool or caulk multi tool to remove the old caulk around the bathtub where it meets the wall. Slide the blade underneath the caulk on the tub side as well as underneath it on the wall side to make it easy to remove. Do not try to pry the caulk off as it could break your blade or crack the surrounding tile.
  • Clean the work area to prep it for caulking.
  • Use the utility knife to cut off the top of the caulk. Aim to make the opening about the width of a coat hanger and cut at a 45 degree angle. A small hole at an angle will give you a clean “bead” of caulk and product the bets results.
  • Fill the tub with water. The weight of the water will pull the tub off the wall very slightly, slowing a better seal.
  • Carefully begin caulking the tub with even pressure to get a clean bead.
  • Smooth the bead down with your finger or a caulk mutlti-tool for a uniform appearance.
  • Rid the tub of any excess caulk.
  • You can drain the tub once the caulk has dried.

Just like that, you have a beautiful new line of caulk on your tub. Practice makes perfect so the more times you play with your caulk, the more likely you’ll get a smooth, even and clean line.
