Regrouting a Shower for Leak Prevention and Durability

Have you noticed water pooling on the floor outside your shower? You may see cracked or discoloured grout lines, and a musty smell may linger despite your efforts to clean. Bubbling paint on the nearby wall or a swollen timber door frame may also indicate excess moisture.

While it’s easy to assume that a pipe has burst behind the wall, water often seeps through damaged grout and worn silicone. A simple process of regrouting and resealing can effectively fix the leak without needing to remove any tiles.

This guide explains when regrouting your shower can successfully resolve a leak and when it may not suffice. You will also discover the regrouting process with Leaking Showers Sealed, including how long you should wait before using the shower again. If you believe the grout is causing the issue, our dedicated shower regrouting page provides a comprehensive overview of our services available in North Richmond, the Hills District, and the North Shore.

Can Regrouting Effectively Fix My Shower Leak?

• Regrouting can effectively stop leaks when water escapes through damaged grout or silicone.
• We remove the old grout and replace it with Ardex EG15 epoxy grout, a non-porous material, and reseal corners and junctions with Ardex neutral cure silicone.
• Your tiles will remain intact, allowing you to repair a leaking shower without extensive renovations or tile removal.
• If the leak originates from a faulty pipe, drain, or tap, you will need to consult a plumber. A damaged membrane beneath the tiles will require tile removal, meaning a regrout alone will not resolve these issues.
• It is recommended to wait at least 24 hours before using the shower again.

Exploring the Importance of Shower Regrouting

Shower regrouting involves removing old, cracked, or mouldy grout from the spaces between your shower tiles and applying fresh grout to restore the seal between the joints. At Leaking Showers Sealed, we use Ardex EG15 epoxy grout, which is non-porous and effectively prevents water and mould penetration, unlike traditional cement grout.

Over time, grout deteriorates due to exposure to hot water, cleaning chemicals, and minor structural movements. This wear and tear can create cracks and pinholes that allow water to seep through the joints, even if the tiles themselves seem unaffected. Often, this damage remains hidden as water accumulates behind the tiles and under the shower floor.

Regrouting restores these joints, reinstating the shower’s watertight integrity. It also removes unsightly stained grout lines, enhancing the overall appearance of your bathroom without the expense and disruption of a full renovation.

Will Regrouting My Shower Truly Resolve the Leaks?

Regrouting effectively addresses leaks when water escapes through damaged grout or silicone, common culprits for shower leaks. The first step is to identify the water’s source to determine if regrouting is the right solution.

When Is Regrouting and Resealing the Optimal Solution?

Regrouting and resealing is the best option if you notice cracked, crumbling, or missing grout, or mould that quickly returns after cleaning. This method is also effective when silicone around corners and the shower base has split or separated. In these cases, the tiles remain intact, and water leaks through the joints.

When Should You Consult a Plumber Instead of Regrouting?

If the leak originates from a pipe within the wall, the shower drain, or a tap, regrouting will not fix the problem. We work closely with plumbers, and if our inspection reveals a problem with a pipe, drain, or tap, we will provide a detailed explanation and refer you to a plumber for further assistance.

What If the Waterproofing Membrane Beneath the Tiles Is Damaged?

The waterproofing membrane is situated behind the tiles and under the shower floor. Prolonged exposure to water through the grout can compromise this membrane. Replacing a damaged membrane involves removing tiles, categorising it as renovation work that we do not perform.

Andreas, who holds NSW licence 89111C, is an expert in waterproofing. Our team is trained to identify a compromised membrane. If we discover during our inspection that your shower needs more than a regrout, we will inform you before proceeding with any work.

Addressing issues early helps protect the membrane. Fresh epoxy grout and new silicone create a barrier against water, making it crucial to repair cracked grout before further damage occurs.

Identifying the Need for Shower Regrouting

Be vigilant for the following signs that indicate your shower may be leaking through the grout and silicone:

• Cracked, loose, or missing grout between the tiles
• Mould that rapidly reappears after cleaning
• Damp odours or visible moisture damage near the shower
• Water pooling outside the shower or leaking into adjacent areas
• Bubbling paint, discoloured walls, or soft floorboards
• Tiles that feel loose or sound hollow when tapped

If you notice any of these symptoms, it is likely that the grout and silicone are no longer effectively holding water within the shower. Tiles that sound hollow when tapped, often referred to as drummy tiles, may need refixing before the shower can be resealed, and we will check for these during our inspection.

What to Anticipate During the Regrouting Process with Leaking Showers Sealed

The regrouting process at Leaking Showers Sealed consists of five key steps, ensuring your tiles remain undisturbed throughout.

Step 1: Inspecting the Shower and Identifying the Leak Source

We conduct a thorough examination of the grout, silicone, tiles, and surrounding areas to determine where the water is escaping. If our inspection reveals an issue with a pipe, drain, or tap, we will inform you before scheduling any regrouting.

Step 2: Removing Old Grout and Silicone

We carefully cut out the old grout and eliminate all existing silicone, including any layers applied over previous silicone. New grout cannot bond properly to old grout, making it essential to start with a clean slate.

Step 3: Thoroughly Cleaning the Tiles and Exposed Joints

We ensure that the tiles and exposed joints are meticulously cleaned to remove soap scum, dust, and mould, guaranteeing that the new grout adheres effectively to a clean surface.

Step 4: Applying Epoxy Grout to Regrout the Shower

We fill the joints with Ardex EG15 epoxy grout. For a shower base seal, we regrout the shower floor, the floor-to-wall junction, and the perimeter. For a complete shower seal, we also regrout every wall grout line.

Step 5: Resealing Corners, Junctions, and Tap Flanges

We apply Ardex ST neutral cure silicone to reseal internal corners and junctions. For a complete shower seal, we also ensure the tap flanges are sealed.

Typically, sealing the shower base takes around 3 to 4 hours, while a full shower seal for both walls and floor generally requires 4 to 5 hours. It is crucial to wait at least 24 hours before using the shower again to allow the grout and silicone to cure properly.

Can Regrouting Completely Remove Shower Mould?

Regrouting effectively eliminates mould that has penetrated the grout, as the mouldy grout is entirely replaced. Surface cleaning with bleach or mould sprays only treats the outer layer, allowing mould to return since it resides within the grout where water is trapped. For more details on why shower grout becomes stained and damaged, please refer to our guide.

Can Regrouting Help You Avoid a Complete Bathroom Renovation?

For many homeowners, regrouting offers a practical solution to delay or even avoid a comprehensive bathroom renovation. If the tiles are in good condition and the leak is traced to the grout and silicone, a regrout and reseal will restore the shower’s watertight integrity. This method also gives you additional time to save for a future renovation.

A regrout, reseal, and thorough clean can also serve as an effective refresh before listing a home for sale or for landlords between tenant occupancies. Our article on regrouting a shower as a cost-effective renovation illustrates how significantly a regrout can enhance a bathroom’s appearance.

Is DIY Regrouting a Shower a Viable Option?

While DIY grout kits are readily available at hardware stores, regrouting a shower correctly is more complex than it appears. Without the right tools and expertise, you risk:

• Damaging or cracking tiles while removing old grout
• Leaving remnants of old grout in the joints, hindering proper bonding of new grout
• Overlooking silicone joints, which are common sources of leaks
• Failing to identify a leak from a pipe or a compromised membrane

If you are uncertain about the water’s source, it is advisable to have the shower inspected before purchasing a DIY kit.

What Is the Cost of Shower Regrouting?

The cost of regrouting a shower varies based on several factors:

• Tile size, as smaller mosaics and 100mm tiles have more grout lines compared to larger 300mm or 600mm tiles
• The dimensions and layout of the shower, including features such as double showers, niches, and additional corners
• The condition of the grout and silicone, including issues like extensive mould, silicone layered over old silicone, or previous repairs needing removal
• Drummy or loose tiles that require refixing before resealing the shower

Regrouting is far more cost-effective than a complete bathroom renovation or retiling. For a cost estimate, please send photos of the shower floor, walls, and the entire shower to sales@leakingshowerssealed.com.au, or call 1300 815 512.

Frequently Asked Questions About Shower Regrouting

How long does it take to regrout a shower?
A shower base seal typically requires about 3 to 4 hours on site, while a complete shower seal for both walls and floor takes around 4 to 5 hours. Please allow at least 24 hours before using the shower again.

<a href=”https://writebuff.com/regrouting-a-shower-a-smart-budget-renovation-idea/”>Will regrouting stop a leak?</a>
Yes, if the leak is due to damaged grout or silicone. Regrouting will not fix leaks from a pipe, drain, or tap, which require a plumber, nor will it address a failed membrane that necessitates tile removal.

How often should a shower be regrouted?
The frequency of regrouting depends on the type of grout used, the bathroom’s ventilation, and the cleaning practices employed. Signs that indicate the need for regrouting include cracked grout, recurring mould, and persistent damp odours. Our article on how long shower regrouting lasts explains the factors that influence this.

Can new grout be applied over old grout?
No. New grout placed over existing grout will not bond properly and will not resolve the leak. It is essential to remove all old grout before regrouting the shower.

Is regrouting covered by warranty?
Yes. A regrout and reseal includes a 10-year warranty on Ardex products and a 7-year workmanship warranty from Leaking Showers Sealed, subject to a site assessment.
