Re Caulk A Bathtub

You may see caulk as tiny detail, but a fresh application can truly make a difference in your bathroom. Caulk is designed to fill cracks and prevent water from leaving the tub or shower. Over time, caulk can crack, leading to structural damage, mold and mildew. Age also tends to discolor caulk, making showers look older and unclean.

For both homeowners and renters alike, re-caulking your tub is an easy fix you can do to spruce up your bathroom. Additionally, this is an easy DIY project. To complete the process, you’ll need to remove the old caulk and replace it with new caulk. Here’s how you can re-caulk your shower or bathtub.

Before you begin the process of replacing the caulk, you must decide what caulk you’d like to use. There are two main types of caulk to use in a bathtub or shower: silicone and latex.


Silicone caulk is completely waterproof, making it ideal for bathrooms. Though it’s incredibly flexible and long-lasting, application and removal is difficult. It also can’t be cleaned up with water; it has to be cleaned up with mineral spirits. Silicone caulk works best on glass and ceramic tile.


This type of caulk is intended to have an easy application, but is not as durable as silicone caulk and tends to crack over time. It tends to be the cheaper option and comes in a wide range of colors. Mistakes can be removed with water. Latex caulk can work on any tile, but specifically, will do well on uneven tile.


Many companies now make a combination caulk of both silicone and latex, maintaining the easy use of latex and the long life of silicone.
