Shower vs Full Bathroom Waterproofing: Which is Better?
Waterproofing might not be the first thing on your mind when designing or renovating a bathroom, but ignoring it could lead to costly mistakes. With water everywhere, should you focus on waterproofing the entire bathroom or just the shower? Let’s dive in and break down the logic behind each approach.

High-Use Areas
If you value cost-effectiveness and your bathroom sees a lot of use, particularly in family homes, the shower recess, vanity, and bath top endure the most water exposure. Waterproofing these high-use areas is not just smart but also economical.
Strategic Choice
Waterproofing only the shower recess provides a highly targeted solution where it’s needed most. The majority of water flow happens in the shower, making it the key battleground against moisture damage. This option gives you the peace of mind of protection, without breaking the bank.

A Smart Long-Term Investment
While focusing on the shower makes sense in the short term, a fully waterproofed bathroom can save you more headaches (and money) over time.
All-Round Protection
Water can sneak into corners, cracks, and edges, so don’t just think about where the water is supposed to go—think about where it might end up. Waterproofing the entire bathroom ensures no hidden leaks or gradual water damage.
Understanding Australian Standards: What You Need to Know
Before you start thinking about waterproofing strategies, it’s essential to grasp what’s legally required in Australia.
AS 3740-2010: The Bare Minimum
The Australian Standard for waterproofing wet areas (AS 3740-2010) outlines the rules for waterproofing in bathrooms. These standards mandate waterproofing at least 150mm up the walls and 1800mm in shower recesses. Complying with these regulations is critical not only for passing inspections but also for insurance purposes.
Why Compliance Matters
Failing to meet these standards can lead to much more than just leaks. It can invalidate your insurance and potentially lead to costly legal problems. So, whether you DIY or hire a pro, it’s crucial to stick to the guidelines.
The Risks
Thinking of cutting corners to save money? Be careful—poor waterproofing can lead to much larger expenses in the long run. Here’s what can happen if your waterproofing isn’t up to scratch:
- Mold and Mildew: These aren’t just unsightly—they can pose serious health risks.
- Water Damage: Over time, moisture can compromise the structural integrity of your home, particularly in timber-framed buildings.
- Costly Repairs: Fixing water damage often requires tearing out tiles and walls, making it an expensive endeavor.
What Are Your Options?
Whether you choose full waterproofing or stick to the shower area, it’s always best to hire professionals for the job. DIY might seem cheaper upfront, but it comes with its risks.
- Professional Expertise: Qualified waterproofers know the best products and techniques to ensure long-lasting protection. They’ll also make sure your bathroom meets legal standards.
- High-Quality Materials: Using industry-approved membranes and sealants is crucial for a durable waterproof barrier. Pros will know which materials are best suited for your specific bathroom layout.
Conclusion: What’s the Best Strategy for You?
The answer depends on your needs, budget, and future plans. If you’re looking for long-term protection and a potential resale boost, go for full waterproofing. But if you’re trying to save some money while still protecting key areas, waterproofing just the shower recess, vanity and bath top is a solid option.
No matter which route you choose, make sure to get in touch with professionals like Superior Waterproofing to ensure the job is done right—keeping your bathroom safe, dry, and compliant with Australian standards.
