Regrouting a Shower: Essential Tips to Avoid Leaks

Have you noticed water pooling on the bathroom floor outside your shower? You may see that the grout lines appear cracked or discoloured, and a persistent musty smell lingers in the air despite your cleaning efforts. You might have even observed the paint on the opposite wall beginning to blister or the timber door frame near the shower swelling due to excessive moisture.

It’s easy to assume that a pipe has burst behind the wall. in many cases, moisture seeps through damaged grout and deteriorated silicone. A simple regrouting and resealing process can effectively resolve that leak without the need for tile removal.

This guide explains when regrouting your shower can effectively fix a leak and when it might not be sufficient. You will learn about the regrouting process when you engage Leaking Showers Sealed, including how long you should refrain from using the shower afterwards. If you suspect that the grout is the source of your problem, our dedicated shower regrouting page offers a comprehensive overview of our regrouting services available in North Richmond, the Hills District, and the North Shore.

Can Regrouting Effectively Resolve My Shower Leak?

• Regrouting can effectively resolve leaks when water escapes through compromised 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 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. If the waterproof membrane beneath the tiles is damaged, tile removal will be necessary, meaning a regrout alone will not resolve these issues.
• It’s advisable to wait at least 24 hours before using the shower again.

The Importance of Shower Regrouting Explained

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 and prevents water and mould from penetrating, unlike traditional cement grout.

Over time, grout deteriorates from exposure to hot water, cleaning chemicals, and minor structural movements. This degradation results in cracks and pinholes that allow water to infiltrate the joints, even when the tiles themselves seem unaffected. Often, this damage goes unnoticed as water accumulates behind the tiles and beneath the shower floor.

Regrouting restores these joints, making the shower watertight once again. It also eliminates unsightly stained grout lines, enhancing the overall appearance of your bathroom without the cost and disruption of a complete renovation.

Will Regrouting Successfully Address My Shower Leaks?

Regrouting effectively resolves leaks when water escapes through compromised grout or silicone, which are common culprits behind shower leaks. The initial step is identifying the source of the water to determine if regrouting is the appropriate solution.

When Is Regrouting and Resealing the Right Choice?

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

When Should You Opt for a Plumber Instead of Regrouting?

If the leak originates from a pipe within the wall, the shower drain, or a tap, regrouting will not resolve the issue. We work alongside 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 Underneath the Tiles Is Compromised?

A waterproofing membrane is situated behind the tiles and beneath the shower floor. Extended exposure to water through damaged grout can compromise this membrane. Replacing a failing membrane requires tile removal, categorising it as renovation work that we do not undertake.

Andreas, holding NSW licence 89111C, has expertise in waterproofing. Our team is trained to identify a compromised membrane. If we discover during our inspection that your shower requires more than just a regrout, we will inform you before commencing any work.

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

Recognising Signs That Your Shower Needs Regrouting

Look out for the following indications that your shower may be leaking through the grout and silicone:

• Cracked, loose, or missing grout between the tiles
• Mould that quickly reappears after cleaning
• Damp odours or visible moisture damage near the shower
• Water pooling outside the shower or leaking into nearby 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’s likely that the grout and silicone are no longer effectively retaining water within the shower. Tiles that sound hollow when tapped, known as drummy tiles, may require 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 consists of five essential steps, ensuring that your tiles remain undisturbed throughout.

Step 1: Inspecting the Shower and Identifying the Leak

We conduct a thorough examination of the grout, silicone, tiles, and surrounding areas to pinpoint where the water is escaping. If our inspection reveals an issue with a pipe, drain, or tap, we will notify you before scheduling 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 effectively to old grout, making it crucial to start with a clean slate.

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, guaranteeing 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, a shower base seal takes around 3 to 4 hours to complete, while a full shower seal for both walls and floor usually requires 4 to 5 hours. You must wait at least 24 hours before using the shower again to allow the grout and silicone to cure properly.

Can Regrouting Effectively Remove Shower Mould?

Regrouting effectively eliminates mould that has penetrated 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 gets trapped. For further information on why shower grout becomes stained and damaged, please refer to our guide.

Can Regrouting Help You Avoid a Full Bathroom Renovation?

For many homeowners, regrouting offers a practical solution to delay or avoid a complete bathroom renovation. If the tiles are in good condition and the leak can be traced to the grout and silicone, a regrout and reseal will restore the shower’s watertight integrity. This approach also provides you with more 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 vacancies. 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 during the removal of old grout
• Leaving remnants of old grout in the joints, which prevents 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 before resealing the shower

Regrouting is significantly 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

<a href="https://writebuff.com/stop-a-leaking-shower-without-removing-tiles-essential-tips-for-homeowners/">How long does it take to regrout a shower?</a>
A shower base seal generally requires about 3 to 4 hours on site, while a complete shower seal for both walls and floor takes approximately 4 to 5 hours. Please allow at least 24 hours before using the shower again.

Will regrouting stop a leak?
Yes, if the leak is due to damaged grout or silicone. Regrouting will not resolve leaks from a pipe, drain, or tap, which necessitate a plumber, nor will it address a failed membrane, which requires 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 habits employed. Signs indicating 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.

<a href=”https://limitsofstrategy.com/shower-reseal-is-it-a-genuine-solution-or-a-quick-fix/”>Can you apply new grout over old grout?</a>
No. New grout applied over existing grout will not bond correctly and will not fix the leak. It is crucial to remove all old grout before regrouting the shower.

Is regrouting covered by a 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.
