This post will outline the steps necessary to remove and replace the grout in your shower. I’ll also provide tips on making the process as easy and efficient as possible. So, if your grout is looking a little worse for wear, read on for instructions on how to replace it with fresh grout.

Step 1: Gather Your Gloves, Replacement Grout, and Grout Saw

The first step when replacing grout in your shower is to gather the necessary supplies. In this case, you’ll need the following tools:

  • Rubber gloves
  • Grout
  • Grout sealer. This will help protect the new grout from water damage and mold growth.
  • A grout saw. This is a specialized tool that’s designed for removing grout from joints. You can find one at your local hardware store or online.
  • Clean towel. Ensure that the grout is dry and debris-free to avoid scratching the tiled surface by wiping it down.
  • Bleach and water. Regular household bleach is fine.
  • Putty knife
  • Abrasive pad

Step 2: Use a Grout Saw To Remove Grout From the Joint

Once you have all of your supplies ready, it’s time to get to work. The next step is to remove the old grout from the joints using a grout saw.

Here are the steps to follow when using a grout saw:

  • Step 1. Protection: Put on your rubber gloves to protect your hands from the grout (it’s alkaline and may dry the skin).
  • Step 2. Cut the grout: Place the grout saw at the edge of the tile joint, and then use a back and forth motion to cut through the grout.
  • Step 3. Do not scratch the tile: Be careful not to scratch the tile’s surface as you do this.
  • Step 4. Continue: Repeat steps 2 and 3 until all of the old grout has been removed from the joints.

Step 3: Clear Out Excess Grout With Bleach and Water

Once the old grout has been removed, it’s time to clean out any leftover debris. To do this, mix a 50-50 solution of bleach and water in a bucket.

Then, use an abrasive pad to scrub the joints clean. This will also kill any mildew or fungus that may be present.

To avoid scratching the tile’s surface, be sure to scrub the surface gently. Pay attention not to use too much pressure as you scrub.

Step 4: Apply the New Grout Using a Spatula

Now that the joints are clean and debris-free, you can apply the new grout. To do that, follow these steps:

  • Step 1. Add some grout: Scoop some grout onto a spatula and spread it into the joint.
  • Step 2. Repeat: Repeat step 1 above until all the joints have been filled with grout.

Note: Don’t worry if some grout gets onto the tile’s surface. You can remove it later.

Step 5: Allow 48–72 Hours for the New Grout To Dry

Once all the joints have been filled with grout, it’s crucial to allow it to dry completely before moving on to the next step.

Typically, it takes 48-72 hours for the grout to dry completely. So, plan accordingly and give it plenty of time to dry before proceeding.

However, if you need to hasten the process, follow these tips:

  • Open the shower door or window to allow air to circulate and speed up the drying process.
  • Use a fan to help circulate the air and speed up the drying process.
  • Avoid using the shower during this time to prevent the grout from getting wet.

Step 6: Clean the Tiles to Remove Excess Grout

Now that the grout has had time to dry, it’s time to clean the tiles. That will remove any excess grout that may be present on the surface of the tile.

To do this, follow these steps:

  • Step 1. Dampen the pad: Dampen the pad with clean water.
  • Step 2. Scrub the tiles: Scrub the tile’s surface to remove any excess grout.
  • Step 3. Do not scratch the tiles: Be careful not to scratch the tile’s surface as you do it.
  • Step 4. Repeat: Repeat steps 1 and 2 until all excess grout has been removed from the tile’s surface; being careful not to scratch the tile.

Step 7: Dry the Work Area With a Clean Towel

Once the excess grout has been removed, it’s time to dry the work area. This will remove any moisture that may be present, allowing the grout to cure properly.

Follow these steps to dry the grout:

  • Step 1: Get the towel
  • Step 2: Wipe down the work area to remove any moisture.

For the best results, ensure that the towel is dry, clean, and absorbent. That way, you can remove as much moisture as possible.

Step 8: Apply Grout Sealer and Let It Dry

The final step is to apply a grout sealer. This will protect the grout from water damage and make it easier to keep clean in the future.

To do that, follow these steps:

  • Step 1: Use a brush or applicator to apply the grout sealer to the joints. Be sure to rub it in well so that it’s evenly distributed.
  • Step 2: Allow the sealer to dry completely before using the shower.
