How to Re Grout a Shower

To regrout your shower, first gather tools like a grout removal tool, grout float, sponge, and grout sealer. Clean and dry the shower tiles thoroughly, then carefully remove the old grout without damaging the tiles. Clear out dust and let the joints dry completely. Mix new grout to a smooth consistency, apply it evenly with a float, then smooth the lines before sealing to protect against moisture. Keep going to uncover tips for a flawless finish.

Tools and Materials Needed for Regrouting

Before you begin regrouting your shower, gather the essential tools and materials to make the process smooth and efficient. You’ll need a grout removal tool or a utility knife to scrape out the old grout safely.

A grout float will help you apply the new grout evenly. Don’t forget a sponge and bucket for cleaning excess grout. Choose the right grout—either sanded or unsanded—based on your tile type.

You’ll also want a grout sealer to protect the grout after it dries. Have safety gear like gloves and goggles handy to protect your skin and eyes.

Finally, a small brush or vacuum can help clear dust and debris from the joints before you start. Having everything ready saves time and frustration.

Preparing the Shower Surface

Once you’ve gathered your tools, you’ll need to thoroughly clean the shower surface to ensure the new grout adheres properly. Start by scrubbing the tiles and grout lines with a strong cleaner or a mixture of vinegar and water to remove soap scum, mildew, and oils.

Rinse well and let the area dry completely.

Check for any loose or cracked tiles and secure or replace them before proceeding. Use a utility knife or scraper to gently clear away any remaining debris or loose grout particles from the joints without damaging the tiles.

Finally, wipe the surface with a damp cloth and allow it to air dry fully.

Taking these steps will create a clean, stable base for applying fresh grout.

Removing Old Grout Safely

Although removing old grout can be a tedious task, doing it carefully ensures you don’t damage your tiles. Start by protecting your eyes and hands with safety goggles and gloves.

Use a grout removal tool or a rotary tool with a grout removal attachment to scrape out the old grout. Work slowly and steadily, applying gentle pressure to avoid chipping your tiles.

Focus on removing grout to about half the depth of the joint. Avoid using metal tools that can scratch the tile surface.

Clear out debris frequently with a vacuum or brush to keep the workspace clean and visible. Taking your time during this step prevents costly tile damage and creates a solid base for new grout to adhere properly.

Cleaning and Drying the Tile Joints

After removing the old grout, you’ll need to thoroughly clean the tile joints to ensure the new grout sticks properly. Start by vacuuming or brushing out any dust and debris left behind.

Then, scrub the joints with a stiff brush and a mixture of water and mild detergent to remove soap scum, mildew, or any remaining residue. Rinse the area well with clean water to wash away loosened dirt and detergent.

Use a sponge or cloth to wipe down the tiles, making sure no cleaning solution lingers. Finally, let the joints dry completely—this might take several hours or even a full day.

Avoid rushing this step, since moisture can weaken the bond and cause the new grout to fail prematurely.

Mixing the New Grout Properly

Before you start mixing, gather all your materials and carefully read the grout manufacturer’s instructions to ensure you use the right water-to-powder ratio.

Pour the recommended amount of grout powder into a clean bucket. Slowly add water while stirring continuously with a margin trowel or a mixing stick. Mix until you get a smooth, peanut butter-like consistency without lumps.

Avoid making the grout too runny, as it won’t set properly, or too dry, which makes it hard to work with.

Let the grout slake by resting it for about 5 to 10 minutes, then stir again briefly before use.

Proper mixing ensures your grout bonds well and stays durable over time, so take your time to get it just right.

Applying the New Grout to the Shower

Once your grout has rested and is ready, you’ll want to apply it carefully to the shower joints using a rubber float. Hold the float at a 45-degree angle and press the grout firmly into the gaps to ensure full coverage.

Work in small sections to keep the grout from drying out before you finish. Move the float diagonally across the tiles to avoid pulling grout out of the joints. Don’t worry about excess grout on the tiles at this stage; you’ll clean that up later.

Make sure all joints are completely filled without air pockets. Take your time and apply consistent pressure to get an even layer. Proper application is key to durable, water-resistant grout that will protect your shower walls.

Smoothing and Shaping the Grout Lines

As you finish pressing the grout into the joints, you’ll want to focus on smoothing and shaping the lines to give your shower a polished look. Use a damp grout float or a rubber grout finishing tool to gently run along the grout lines, removing excess grout and pressing it firmly into the joints.

Be careful not to dig too deep, as this can cause uneven lines. Next, take a damp sponge and lightly wipe the tile surfaces in a circular motion, refining the grout lines further and cleaning off any remaining residue. Rinse the sponge frequently to avoid spreading grout haze.

This step ensures crisp, smooth grout lines and a neat finish, setting the stage for proper drying before moving on to sealing.

Sealing the Grout for Long-lasting Protection

Although the grout may look perfect after smoothing, you’ll want to seal it to protect against moisture, stains, and mildew. Start by ensuring the grout is completely dry—usually 48 to 72 hours after application.

Choose a high-quality grout sealer designed for showers. Using a small brush or applicator, apply the sealer evenly along the grout lines, avoiding excess on the tiles. Let it soak in for about 10 minutes, then wipe off any residue with a clean cloth.

Apply a second coat if recommended by the product instructions. Proper sealing helps prevent water damage and keeps your grout looking fresh longer.

Reseal your grout every six months to maintain its protective barrier and extend your shower’s lifespan.
