Everything you need to caulk a shower

In the case of caulking a shower, being equipped with the right tools for the job will make things quick and efficient. To seal a shower, you will need a few items, many of which you probably already have on hand. To be ready for anything, you will need caulk removal tools like a box cutter, silicone caulk remover, and a joint scraper. For keeping a clean, smooth sealant area, you will require painter’s tape and a caulking gun.

Once you have cleared the shower seams of old debris, pick up a tube of caulk and get sealing! To finish off your DIY shower repair, smooth it with a tool — or a wet finger — and wipe away residue with a gloved hand or a paper towel. 

Caulking a shower door or stall: Preparation

So, you have your tools and now it’s time to caulk your shower stall or door. To perform this DIY job like a contractor, you will need to prepare the following steps: 

  1. Unhinge old caulk. First, use your box cutter to make a line down the centre of the old caulk. Do this slowly to protect the shower lining or tub from being scratched or damaged.
  2. Remove the previous sealant by using a gloved hand to pull away the remaining sealant. Use a joint scraper or caulk remover to unhinge any pesky residue.
  3. Wash the seams with water and dry them as thoroughly as possible before adding new caulk to the space.
  4. Use painter’s tape along all the seams in your shower or bathtub. This added element will keep your bead lines straight at awkward angles and in hard to reach areas!

How to caulk a shower surround

Once you’ve prepared everything, the caulking part will be easy! Just run your caulk gun along the seams in a steady, smooth line. Start in the corners, and work slowly and carefully. Make sure to hold the gun in a 45-degree angle and perform with even pressure. Pass your wet finger or a tool over top to smooth out the bead. Carefully remove the tape, and allow the caulk time to dry.
