Have you noticed cracks or discolouration in your shower’s grout?
Old, worn-out grout not only dulls the appearance of your shower but can also lead to mould, mildew, and even water damage over time. Shower regrouting is an essential task for any homeowner looking to maintain a clean and watertight bathroom. With just a bit of effort, you can completely revitalise your shower without needing professional installation or expensive materials.
This comprehensive guide will walk you through every step of the process so you can achieve that sparkling finish, just like the pros.
Why Regrouting is Essential for Your Shower
Preventing Water Damage
When grout deteriorates, it opens up tiny pathways for water to seep into the walls and floors surrounding your shower. This might seem harmless at first, but over time, the moisture buildup can lead to extensive water damage. The problem with water seeping into these hidden areas is that it can go unnoticed until it’s severe, resulting in costly repairs. Regrouting a shower is a preventative measure that can save you from the hassle of extensive water damage in the future.
Improving Hygiene
Did you know that worn-out grout lines can harbour mould, mildew, and bacteria? Over time, grout can become porous, especially in high-humidity areas like bathrooms, which makes it the perfect breeding ground for these unsightly and unhealthy intruders. Regular shower regrouting keeps your bathroom cleaner, fresher, and healthier. A hygienic bathroom isn’t just about aesthetics; it’s crucial for the overall health of everyone in the household.
Aesthetic Appeal
Let’s face it—a shower with cracked, stained grout just doesn’t look inviting. Regrouting is like giving your bathroom an instant facelift, restoring its fresh and clean appearance. Even if you’ve kept your tiles spotless, deteriorating grout can make your shower appear neglected and outdated. When you invest the time in regrouting, you’ll bring new life to the entire space, making it look polished and well cared for.
Tools and Materials You’ll Need
Essential Tools and Materials
Before diving into the regrouting process, make sure you have everything you need. Here’s a list of essential tools and materials to help you tackle your shower regrouting like a pro:
- Grout Removal Tool: You’ll need either a manual grout saw or an electric grout removal tool to clear out the old grout.
- Grout Float: This tool helps you spread new grout evenly across the tiles.
- Sponge: A damp sponge is crucial for cleaning off excess grout as you work.
- Bucket: Handy for mixing grout and rinsing your sponge.
- Grout Sealant: This optional step helps protect the grout from future staining and moisture.
- New Grout: Choose grout that’s suitable for showers—typically sanded or unsanded depending on the tile gap size.
Choosing the Right Grout for Your Shower
Selecting the right type of grout can make a big difference in the durability of your regrouting job. Shower grout needs to withstand constant exposure to moisture, so consider using epoxy grout, which is water-resistant and highly durable, or cement-based grout with added sealant for a more budget-friendly option. Epoxy grout is generally more resistant to stains and lasts longer, making it a preferred choice for high-use areas like showers.
Pro Tips for Grout Selection
For showers, it’s typically best to avoid sanded grout if the tile gaps are narrower than 1/8 inch, as it can scratch certain tiles. We recommend checking the manufacturer’s instructions for your tiles or consulting a tile professional if you’re unsure. At AllSealed WA, we specialise in helping our clients select the right grout type for maximum longevity and aesthetics in their bathroom spaces.
Step-by-Step Guide to Regrouting a Shower
Step 1: Remove the Old Grout
Start by using a grout removal tool to carefully scrape out the old grout from between the tiles. While this can be time-consuming, it’s an essential step to ensure the new grout adheres properly. Use gentle, steady pressure to avoid chipping the edges of the tiles. A manual grout saw is effective for smaller jobs, but if you have a large shower area, an electric grout remover might save you a lot of time and effort. Safety goggles and gloves are recommended for this part, as bits of grout can fly up during removal.
Step 2: Clean the Surface Thoroughly
Once you’ve removed all the old grout, clean the surface thoroughly to ensure there’s no dust, debris, or leftover grout residue that could interfere with the new application. Use a tile cleaner or a mixture of warm water and vinegar to scrub between the tiles, paying close attention to the grout lines. At AllSealed WA, we advise using a soft brush for this step to avoid scratching the tiles.
Step 3: Mix the New Grout
Follow the manufacturer’s instructions carefully to mix your grout. The consistency should be similar to peanut butter—not too runny, yet spreadable. This is key to ensuring it adheres well between the tiles. Make sure to only mix what you need for each session, as grout can harden quickly once it’s prepared.
Step 4: Apply the New Grout
Using a grout float, apply the grout at a 45-degree angle, pressing it firmly into the spaces between the tiles. Spread the grout evenly to ensure all gaps are filled and there are no air pockets. This step is essential for achieving a professional finish. The 45-degree angle technique helps press the grout fully into the joints, ensuring better coverage and durability.
Step 5: Clean Excess Grout
Once the grout has been applied, use a damp sponge to wipe off the excess. It’s crucial to rinse the sponge frequently and avoid dragging grout out of the lines. This step ensures a clean, neat finish. Avoid over-wetting the sponge, as this can dilute the grout and weaken the bond.
Step 6: Allow Grout to Cure
Curing is vital for the durability of your new grout. Leave the grout untouched for the recommended drying time (usually 24-48 hours). Avoid using the shower or exposing the grout to any moisture during this period.
Step 7: Apply Grout Sealant (Optional but Recommended)
Once your grout has been cured, applying a grout sealant can add an extra layer of protection against water and stains. Use a small brush or roller to apply the sealant, following the manufacturer’s directions. Grout sealant is especially useful in shower areas, where water exposure is frequent.
Common Mistakes to Avoid
Skipping Surface Preparation
One of the most common mistakes in shower regrouting is not thoroughly preparing the surface before applying new grout. Any remaining dust, grime, or old grout can prevent the new grout from adhering properly. For best results, take the time to clean the tiles thoroughly after removing old grout.
Not Sealing the Grout
Many DIY enthusiasts overlook sealing the grout, thinking it’s an optional step. However, unsealed grout is more vulnerable to moisture, leading to stains and deterioration. Sealing the grout adds a layer of defence against mildew and keeps your shower looking new for longer. At AllSealed WA, we highly recommend this step for maximum durability.
Using the Wrong Type of Grout
Choosing the wrong grout can lead to issues like cracks or discolouration. Showers require moisture-resistant grout, such as epoxy or cement-based options, for durability. Avoid sanded grout in narrow spaces or on tiles prone to scratching, as this can lead to damage.

While regrouting is a manageable DIY project, there are times when professional help is essential. If you notice large cracks in your tiles, water leakage, or mould growth behind the tiles, it may be a sign that the issue goes beyond grout. Our team at AllSealed WA has the expertise to handle complex cases and can assess any underlying problems that could affect the longevity of your grout.

Frequently Asked Questions
Q: How often should I regrout my shower?
A: The frequency of regrouting your shower depends on the condition of the grout and the level of moisture exposure. On average, grout can last between 8- to 15 years if properly maintained and sealed. However, if you start noticing cracks, discolouration, or mould growth, it’s time to consider regrouting sooner. Regular cleaning and applying a grout sealer every 1-2 years can help prolong the life of your grout, especially in high-moisture areas like showers.
Q: Can I put new grout over old grout?
A: Technically, adding new grout over old grout may seem like a quick fix, but it’s not recommended for a durable, clean result. Applying fresh grout over existing grout can lead to poor adhesion and uneven application, making the new layer prone to cracking and flaking over time. For the best outcome, remove the old grout thoroughly before applying new grout. This ensures the new grout bonds properly and results in a smooth, seamless finish.
Q: Do I need to seal my grout after regrouting?
A: Yes, sealing grout is highly recommended after regrouting, especially in wet areas like showers. Grout is porous and can absorb moisture, which can lead to mould, mildew, and stains over time. A grout sealer provides a protective barrier, helping to repel water and prevent stains. For shower areas, we recommend reapplying the grout sealer every 1-2 years to keep the grout in top condition.
Q: What type of grout should I use for my shower?
A: For showers, epoxy grout is generally the best option as it is highly resistant to moisture, stains, and mildew, making it ideal for high-use, wet areas. Cement-based grout can also be used if properly sealed, and it’s more budget-friendly than epoxy. If your tile gaps are narrow (less than 1/8 inch), use unsanded grout to avoid scratching the tiles. For wider gaps, sanded grout provides better strength and coverage.
Q: Can I regrout my shower by myself, or should I hire a professional?
A: Regrouting a shower can be done as a DIY project if you have patience and the right tools. However, the process can be time-consuming and requires attention to detail to avoid damaging the tiles. If you’re dealing with extensive mould, and uneven tiles, or you’re looking for a professional-grade finish, hiring a professional like AllSealedWA is the best choice. Our team has the experience and equipment to handle all aspects of shower regrouting efficiently, giving you a flawless result.
Q: How long does it take to regrout a shower?
A: The time needed to regrout a shower depends on the size of the area and the condition of the old grout. For a standard shower, regrouting can take around 4-8 hours. This includes grout removal, surface preparation, applying new grout, and cleaning. Keep in mind that grout typically needs 24-48 hours to cure fully, so it’s best to avoid using the shower for at least two days after regrouting for the best results.
Q: Is it normal for grout to crack over time?
A: Yes, grout can crack over time due to factors like moisture, temperature changes, and structural movement. However, if cracking happens frequently or soon after application, it could be a sign of poor installation or underlying issues. In bathrooms, high humidity and constant water exposure can weaken grout. Applying a grout sealer and regular cleaning can help prevent premature cracking. If you notice recurring cracks, it may be time to regrout or consult a professional to check for underlying issues.
Q: Can I use my shower immediately after regrouting?
A: It’s essential to allow the grout to cure fully before using your shower. Grout usually requires 24-48 hours to set and harden. Using the shower too soon can compromise the grout’s durability and cause it to weaken or dislodge. To ensure a long-lasting finish, wait at least two days before exposing the newly grouted area to water. Additionally, if you’ve applied grout sealer, allow the sealer to dry according to the manufacturer’s instructions.
Q: How can I keep my grout looking clean and fresh after regrouting?
A: Keeping grout clean and fresh requires regular maintenance. Wipe down the shower walls with a squeegee or towel after each use to minimise water buildup. Clean the grout with a gentle tile cleaner or a mixture of vinegar and water every few weeks to remove soap scum and prevent mildew growth. Applying a grout sealer annually can also help repel stains and keep your grout looking new. At AllSealedWA, we recommend avoiding harsh chemicals or bleach, as these can erode grout over time.
