Regrouting a Shower for Leak Prevention and Durability

Have you noticed water pooling on the bathroom floor outside your shower? You may see cracked or discoloured grout lines, and a persistent musty smell lingers despite your diligent cleaning efforts. You might observe bubbling paint on the nearby wall or the wooden door frame swelling due to excessive moisture.

It’s easy to assume that a pipe has burst behind the wall. more often than not, water seeps through damaged grout and worn-out silicone. A simple regrouting and resealing can effectively fix that leak without needing to remove a single tile.

This guide outlines when regrouting your shower can effectively fix a leak and when it may not suffice. You will also discover the regrouting process when you choose to work with Leaking Showers Sealed, including how long to wait before using the shower again. If you suspect the grout is the issue, our dedicated shower regrouting page provides a comprehensive overview of our services in North Richmond, the Hills District, and the North Shore.

Can Regrouting Effectively Fix My Shower Leak?

• Regrouting can successfully 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 using Ardex neutral cure silicone.
• Your tiles stay intact, allowing you to resolve a leaking shower without extensive renovations or tile removal.
• If the leak originates from a faulty pipe, drain, or tap, consulting a plumber will be necessary. A compromised membrane beneath the tiles will require tile removal, meaning that a regrout alone will not solve these issues.
• It is recommended to wait at least 24 hours before using the shower again.

Exploring the Significance of Shower Regrouting

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

Over time, grout deteriorates due to exposure to hot water, cleaning chemicals, and minor structural shifts. This wear leads to cracks and pinholes that allow water to seep through the joints, even when the tiles appear unaffected. Often, this damage goes unnoticed as water accumulates behind the tiles and beneath the shower floor.

Regrouting reinstates these joints, restoring the watertight integrity of the shower. It also removes unsightly stained grout lines that can make a clean bathroom look dated, all without the cost and disruption of a full renovation.

Will Regrouting My Shower Resolve the Leaks?

Regrouting effectively tackles leaks when water escapes through compromised grout or silicone, common culprits of shower leaks. The first step is to identify the source of the water to determine if regrouting is appropriate.

When Is Regrouting and Resealing the Optimal Solution?

Regrouting and resealing is the best choice when you notice cracked, crumbling, or missing grout, or mould that returns shortly after cleaning. This approach is also effective if the silicone around corners and the shower base has split or come loose. In these cases, the tiles remain intact, and the 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 address the problem. We collaborate with plumbers, and if our inspection reveals an issue 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?

A waterproofing membrane is situated behind the tiles and under the shower floor. Extended exposure to water through the grout can damage this membrane. Replacing a failing membrane necessitates tile removal, classifying 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 detect a compromised membrane. If we find during our inspection that your shower requires more than a regrout, we will inform you before commencing any work.

Addressing issues at the first signs of trouble helps protect the membrane. Fresh epoxy grout and new silicone create a barrier against water, making it crucial to deal with cracked grout before further damage occurs.

Recognising 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 reappears quickly after cleaning
• Damp smells or visible moisture damage near the shower
• Water pooling outside the shower or leaking into surrounding areas
• Bubbling paint, discoloured walls, or soft floorboards
• Tiles that feel loose or sound hollow when tapped

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

What to Anticipate During the Regrouting Process with Leaking Showers Sealed

The regrouting process at Leaking Showers Sealed follows 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 a problem with a pipe, drain, or tap, we will inform you before arranging any regrouting.

Step 2: Removing Old Grout and Silicone

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

Step 3: Thoroughly Cleaning the Tiles and Exposed Joints

We ensure the tiles and empty joints are meticulously cleaned to eliminate soap scum, dust, and mould, ensuring that the new grout adheres effectively to a pristine 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 ensure the tap flanges are also sealed.

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

Can Regrouting Eliminate Shower Mould?

Regrouting effectively eliminates mould that has infiltrated the grout, as the mouldy grout is replaced. Surface cleaning with bleach or mould sprays only addresses the top layer, allowing mould to return since it resides within the grout where water is trapped. For further insights into 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 postpone or avoid a full 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 approach also provides you with 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, correctly regrouting a shower is more complex than it appears. Without the right tools and expertise, you risk:

• Damaging or cracking tiles during the removal of old grout
• Leaving remnants of old grout in the joints, preventing 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 source of the water, it is wise 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 prior to resealing the shower

Regrouting is significantly more cost-effective than a full bathroom renovation or retiling. For a cost estimate, please send photos of the shower floor, walls, and the complete 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 resolve leaks originating 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 you apply new grout over old grout?
No. New grout applied over existing grout will not bond properly and will not fix 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, contingent upon a site assessment.
