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 even after extensive cleaning. You might also have observed bubbling paint on the nearby wall or a timber door frame that has swollen due to excess moisture.

It’s easy to jump to the conclusion that a pipe has burst behind the wall. More often than not, water seeps through cracked grout and deteriorated silicone. A simple regrouting and resealing can effectively fix that leak without having to remove a single tile.

This guide will explain when regrouting your shower can effectively fix a leak and when it may fall short. You will also learn about the regrouting process when you choose to work with Leaking Showers Sealed, including how long you’ll need to wait before using the shower again. If you suspect that the grout is the cause of the leak, 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 Truly Fix My Shower Leak?

• Regrouting can effectively halt 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, while resealing corners and junctions with Ardex neutral cure silicone.
• Your tiles remain untouched, allowing you to fix a leaking shower without major 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 regrouting alone won’t address these issues.
• It’s recommended 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 fresh 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 from penetrating like traditional cement grout.

Over time, grout deteriorates due to exposure to hot water, cleaning chemicals, and minor structural movements. This degradation creates cracks and pinholes that allow water to seep through the joints, even when the tiles themselves seem unaffected. Often, this damage remains hidden 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 expense and disruption of a complete renovation.

Will Regrouting My Shower Eliminate the Leaks?

Regrouting effectively addresses leaks when water escapes through compromised grout or silicone, which are frequent culprits of shower leaks. The first step is to identify the source of the water to determine if regrouting is the right solution.

When Is Regrouting and Resealing the Optimal Solution?

Regrouting and resealing is ideal when you notice cracked, crumbling, or missing grout, or mould that keeps returning after cleaning. This method is also effective if the silicone around corners and the shower base has split or detached. In these situations, the tiles remain intact, and water leaks through the joints.

When Should You Contact a Plumber Instead of Opting for Regrouting?

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

A waterproofing membrane is located behind the tiles and beneath the shower floor. Prolonged exposure to water through the grout can harm this membrane. Replacing a failing membrane necessitates tile removal, categorising it as renovation work that we do not perform.

Andreas, holding NSW licence 89111C, is a specialist in waterproofing. Our team is trained to identify a compromised membrane. If we discover during our inspection that your shower requires more than a regrout, we will notify 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 tackle cracked grout before further damage occurs.

Recognising the Signs That Shower Regrouting Is Necessary

Watch for these indicators that suggest your shower might be leaking through the grout and silicone:

• Cracked, loose, or missing grout between the tiles
• Mould that quickly returns after cleaning
• Damp smells 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 is 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, might 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 comprises five essential steps, ensuring your tiles remain undisturbed throughout.

Step 1: Inspecting the Shower and Identifying the Leak Source

We thoroughly examine the grout, silicone, tiles, and surrounding areas to pinpoint where the water is escaping. If our inspection uncovers a problem 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 effectively to old grout, making it vital to start with a clean surface.

Step 3: Cleaning the Tiles and Exposed Joints Thoroughly

We ensure the tiles and empty joints are cleaned thoroughly to remove 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. You must wait at least 24 hours before using the shower again to allow the grout and silicone to cure properly.

Can Regrouting Eradicate Shower Mould?

Regrouting effectively removes mould that has penetrated the grout, as the mouldy grout is replaced. Surface cleaning with bleach or mould sprays only treats the outer layer, allowing mould to return because it resides within the grout where water is trapped. For more 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 postpone or avoid a complete 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 watertight integrity of the shower. 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, regrouting a shower correctly is more complicated than it appears. Without the proper tools and expertise, you risk:

• Damage or cracking of tiles during the removal of old grout
• Leaving remnants of old grout in the joints, which can impede the 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 prudent 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 such as 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 regrouting a shower typically take?
A shower base seal usually 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?
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 that 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 practices 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 influencing 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 comes with a 10-year warranty on Ardex products and a 7-year workmanship warranty from Leaking Showers Sealed, subject to a site assessment.
