Fixture & Waste Replacement
Leaking or outdated shower fixtures and floor wastes can cause hidden water damage that worsens over time. Our fixture and waste replacement service addresses these issues efficiently, ensuring your shower functions correctly and drains properly.
We replace faulty shower heads, mixers, taps, and floor wastes using quality components that meet modern standards. Proper installation is key to preventing leaks, blockages, and water pooling, which can compromise waterproofing systems.
Whether you’re upgrading worn fixtures or fixing a persistent leak, our precise replacement process ensures reliable performance and long-term protection. This service is an essential part of maintaining a safe, leak-free shower and preventing costly future repairs.
Why Sealing Is Important
Sealing provides a protective barrier that is especially important in wet and high-exposure areas like bathrooms, showers, balconies, kitchens, and pool surrounds.
Reduces water absorption
Helps prevent mould and mildew growth
Minimises staining from soaps, oils, and minerals
Protects grout from crumbling and erosion
Extends the life of tiles, grout, and stone
Makes cleaning easier and more effective
Types of Sealers We Use
We assess each surface to ensure the most suitable sealer is used for maximum performance and longevity.
Penetrating (Impregnating) Sealers
These sealers soak deep into the grout or stone without changing the surface appearance. They:
Maintain the natural look and finish
Allow the surface to breathe
Provide long-lasting internal protection
Are ideal for bathrooms, showers, and outdoor areas
Surface (Topical) Sealers
These sealers form a protective layer on the surface. They:
Can enhance colour or sheen
Provide a visible barrier
Are typically used where a decorative finish is desired

FAQs About Leaking Shower Repairs & Tile Regrouting
Do I need to rip up my tiles to fix a leaking shower?
The majority of shower leaks are caused by failing grout or silicone, not the plumbing or tiles themselves. We use a specialised system to remove the old, compromised sealant and replace it with a high-grade waterproof epoxy and sanitary silicone. This repairs the leak and creates a watertight seal without the noise, mess, or heavy cost of a full bathroom renovation, making it ideal for homeowners wanting a quick and cost effective solution.
Who will actually be doing the work at my home?
When you book Coastal Seal & Grout, you get Nigel, the owner. We are a sole-trader business, not a franchise. Nigel personally handles every job—from the initial quote and inspection right through to the final clean-up. This ensures consistent quality, clear communication, and a tradesman who treats your home as if it were his own.
What products do you use, and is the work guaranteed?
We only use premium, commercial-grade materials designed to withstand the humid Sunshine Coast climate. This includes stain-resistant epoxy grouts (far more durable than standard cement grout) and high-quality sanitary silicones. All completed shower seals and bathroom jobs come with a 7-year workmanship warranty, giving you complete peace of mind.

How much do shower, tile, and grout repairs cost?
The cost of leaking shower repairs, tile regrouting & cleaning, silicone replacement, and pool or outdoor tile repairs in the Sunshine Coast depends on several factors:
Size of the area – larger showers, bathrooms, or outdoor areas require more materials and time.
Extent of the damage – cracked grout, worn silicone, or leaking showers vary in complexity.
Type of service – whether it’s a full shower reseal, grout regrouting, silicone replacement, or pool tile repair.
We provide upfront, transparent pricing after an inspection. This ensures you know the full cost before any work begins, and we can recommend the most cost-effective solution for your home or property.
