Re-grouting a shower is a relatively simple task that can be completed in a few hours. However, it is important to take your time and do the job properly, as a poorly grouted shower can lead to water damage and other problems. In this article, we will provide you with a step-by-step guide on how to re-grout a shower, including tips on how to remove the old grout, apply the new grout, and seal the grout lines. We will also provide you with some troubleshooting tips in case you encounter any problems along the way.
Before you begin, it is important to gather all of the necessary tools and materials. You will need a grout saw, a grout float, a bucket, a sponge, a scrub brush, and a sealant. You will also need to purchase new grout that is specifically designed for showers. Once you have gathered all of your supplies, you are ready to begin the process of re-grouting your shower.
The first step is to remove the old grout. This can be done using a grout saw. Be careful not to damage the tiles when removing the old grout. Once the old grout has been removed, you can begin applying the new grout. Use a grout float to apply the grout to the shower walls and floor. Be sure to press the grout firmly into the joints between the tiles. Once the grout has been applied, you can use a sponge to smooth out the grout lines. Allow the grout to dry for at least 24 hours before applying a sealant. The sealant will help to protect the grout from water damage and staining.
Removing Old Grout
Before you can re-grout your shower, you need to remove the old grout. This can be a tedious task, but it’s important to do it properly in order to ensure that the new grout will adhere properly.
Safety Precautions
Before you begin, be sure to wear gloves and a dust mask. Grout dust can be irritating to the skin and lungs, so it’s important to protect yourself.
Tools You’ll Need
- Grout saw
- Grout removal tool
- Bucket
- Sponge
- Water
- Vinegar (optional)
Steps
1. Score the grout. Use a grout saw to score the grout lines. This will help to break the seal between the grout and the tiles.
2. Remove the grout. Use a grout removal tool to remove the old grout. Be careful not to damage the tiles.
3. Clean the tiles. Once the grout has been removed, clean the tiles with a sponge and water. You can also use a vinegar solution to help remove any remaining grout residue.
4. Dry the tiles. Allow the tiles to dry completely before re-grouting.

Spreading and Smoothing Grout Lines
Once the grout has been mixed, it’s time to spread it into the grout lines. Use a grout float or a small rubber squeegee to apply the grout to the lines. Tilt the float or squeegee at a 45-degree angle to the grout line and apply firm pressure to force the grout into the space between the tiles. Work in small sections, about 2-3 square feet at a time.
After the grout has been applied, use a damp sponge to smooth out the surface of the grout lines. Wipe the sponge across the grout lines in a diagonal motion to remove any excess grout and create a smooth, even surface. Be sure to rinse the sponge frequently to prevent excess grout from building up on the tiles.
Allow the grout to set for the time specified on the manufacturer’s instructions. This will typically be around 20-30 minutes. Once the grout has set, use a clean, dry cloth to wipe away any remaining residue from the tiles. Be sure to wipe in the direction of the grout lines to avoid smudging the grout.
The final step is to seal the grout lines. Grout sealant helps to protect the grout from water damage and stains. Apply the sealant to the grout lines using a small brush or a sponge. Allow the sealant to dry for the time specified on the manufacturer’s instructions. Once the sealant has dried, your shower is ready to use.

Sealing the Grout
Preparing the Surface
Before applying the sealant, ensure the grout is completely dry. Damp grout will prevent the sealant from adhering properly. If necessary, use a hair dryer or fan to dry the grout.
Choosing the Right Sealant
Select a sealant specifically designed for showers, as these products are formulated to resist moisture and mildew. Look for sealants with a silicone or epoxy base, which provide excellent waterproofing capabilities.
Applying the Sealant
Apply the sealant along the grout lines using a caulk gun. Hold the gun at a 45-degree angle and move along the grout line in a smooth motion. Ensure there are no gaps or breaks in the sealant.
Smoothing the Sealant
Use a damp finger or a grout finishing tool to gently smooth the sealant and remove any excess. Be careful not to overwork the sealant, as this can weaken its bond.
Curing the Sealant
Allow the sealant to fully cure according to the manufacturer’s instructions. Most sealants will require 24-48 hours to cure completely. Avoid using the shower during this time.
Additional Tips
To ensure the grout remains waterproof and protected, reseal the grout annually or as recommended by the sealant manufacturer. Use a mildew-resistant sealant to prevent the growth of mold and mildew. Consider using a grout sealer with a colorant to enhance the grout’s appearance and match the tile’s color.
Proper Grout Maintenance: Daily Cleaning
To keep your grout looking its best and prevent premature wear and tear, it’s essential to establish a regular cleaning routine. Here are the steps to follow for daily cleaning:
Step 1: Gather Your Supplies
You’ll need a clean cloth or sponge, mild dish soap, and a bucket of warm water.
Step 2: Wet the Grout
Dip the cloth or sponge into the warm water and gently wet the grout.
Step 3: Apply Dish Soap
Apply a small amount of mild dish soap to the cloth or sponge and gently rub it over the grout.
Step 4: Scrub the Grout
Use circular motions to scrub the grout, working any dirt or grime free. Avoid using abrasive materials that can damage the grout.
Step 5: Rinse the Grout
Dip the cloth or sponge into the clean water and rinse the grout thoroughly. Repeat until all soap residue is removed.
Step 6: Dry the Grout
Use a clean cloth or towel to dry the grout. This will help prevent water from seeping into the grout and causing damage.
Step 7: Inspect the Grout for Additional Cleaning Needs
After daily cleaning, inspect the grout for any stains or discoloration that may require additional cleaning. If you notice any issues, proceed to the appropriate cleaning method as described in our guide.
Troubleshooting Common Grout Issues
Discolored Grout
Discoloration can result from mold, mildew, or stains. Clean the grout with a bleach solution, ammonia, or a commercial grout cleaner.
Cracked Grout
Grout can crack from movement in the tile or from improper installation. Repair cracks immediately to prevent water damage.
Loose Grout
Grout can become loose due to improper sealing or water damage. Firmly press new grout into the joints and seal it when dry.
Stained Grout
Stains from hair dyes, makeup, or soap scum can be difficult to remove. Try using a commercial stain remover or a paste made from baking soda and water.
Darkened Grout
Grout can darken over time due to dirt, soap scum, or hard water minerals. Clean the grout regularly and apply a grout sealer to protect it.
Moldy Grout
Mold can grow in moist environments. Treat moldy grout with a bleach solution, ammonia, or a commercial mold cleaner.
Efflorescence
Efflorescence is a white, powdery substance that forms on grout when water evaporates. Remove efflorescence by scrubbing it with a vinegar solution.
Popped Grout
Grout can pop out of the joints due to moisture or excess pressure. Re-apply grout and seal it properly to prevent further damage.
Scrubbing Grout
Use a soft-bristled brush to scrub grout. Avoid using harsh chemicals or abrasive materials that can damage the grout.
Sealing Grout
Applying a grout sealer after cleaning helps protect the grout from stains and water damage. Allow the sealer to dry completely before using the shower.
How to Re-Grout a Shower
