Understanding Bathroom Waste Traps: Bottle Traps, S-Traps & P-Traps
When planning a bathroom renovation, few details are as overlooked—yet as vital—as choosing the right waste trap. These unassuming components do more than channel water away; they protect your home from odours, blockages, and costly plumbing issues. At The Blue Space, we’ve spent years guiding Australian homeowners and tradies through the maze of options. Let’s break down the essentials: bottle traps, S-traps, and P-traps.
Bottle Traps: Where Style Meets Practicality
If you’ve ever admired a sleek, minimalist bathroom, chances are it used a bottle trap. These traps get their name from their cylindrical shape, resembling an upside-down bottle. Their compact profile is perfect for modern vanities or wall-hung basins where space is tight. The genius lies in their design: a removable lower section lets you clear hair or debris without disassembling the entire unit.
At The Blue Space, we stock bottle traps designed for durability. The ADP traps range, for instance, uses chrome-plated brass to resist corrosion—ideal for coastal areas. Prefer a budget-friendly option? The Indigo bottle traps line offers lightweight PVC models that won’t clash with your decor.
Why bottle traps shine:
-
Space-saving: Fits snugly under shallow basins, like those in our bathroom basins collection.
-
Easy access: Unscrew the base to remove blockages—no need for specialised tools.
-
Aesthetic flexibility: Brushed gold, matte black, or classic chrome? Match your tapware for a polished look.
Pair one with a Nero Tapware bottle trap set to create a cohesive, designer-style space.
S-Traps: The Outdated Workhorse
S-traps were once the backbone of Australian plumbing. Their S-shaped bend traps water to block sewer gases, but they come with a catch. In high-pressure systems (think apartment buildings), the water seal can get siphoned out, letting unpleasant odours seep into your bathroom. Many local councils now ban new S-trap installations—though they’re still found in older homes.
If you’re renovating a heritage property, our Turner Hastings wastes & traps range offers period-appropriate designs with updated materials. But for most projects, we’d suggest upgrading to a P-trap or bottle trap.
Key things to know about S-traps:
-
Check your local rules: Some areas prohibit repairs or replacements.
-
High maintenance: Inspect the seal monthly to prevent breakdowns.
-
Not for new builds: Modern codes favour safer alternatives.
P-Traps: The Gold Standard for Modern Homes
P-traps are the go-to choice for Australian plumbers—and for good reason. Their horizontal pipe (shaped like a “P” on its side) holds water consistently, stopping gases from entering your home. They’re also less prone to siphonage, making them compliant with current building standards.
Our collection includes versatile options for sinks, showers, and even freestanding baths from our bathtubs collection. For heavy-duty use, the Phoenix wastes & traps line offers commercial-grade brass construction.
Why P-traps win:
-
Reliable protection: The water seal rarely fails when installed correctly.
-
Versatile fit: Works with most fixtures, including kitchen sinks from our kitchen sinks collection.
-
Easy to clean: A removable inspection panel lets you tackle blockages fast.
Choosing the Right Trap: A Step-by-Step Guide
1. Measure Your Space
Bottle traps suit tight spots, like under a wall-hung basin. For deeper cabinets, P-traps provide better access. Struggling with an awkward layout? The Meir wastes & traps range includes adjustable models.
2. Match Your Style
A chrome P-trap pairs seamlessly with modern tapware, while a matte black bottle trap adds contrast to industrial designs. Browse our bathroom accessories for coordinating details like towel rails.
3. Stay Compliant
Local regulations vary. In Queensland, for example, S-traps are banned in new builds. Our team can help you navigate regional codes—just ask.
Installation Tips from the Pros
-
Avoid Overtightening: This warps plastic threads, causing leaks. Hand-tighten, then give a quarter-turn with pliers.
-
Slope Pipes Correctly: P-trap horizontal pipes need a slight downward tilt (2-4mm per metre) to prevent standing water.
-
Use Sealant Sparingly: A pea-sized dab of silicone on metal joints is enough. Excess sealer can crack over time.
For tricky setups—like connecting a Fienza bath wastes unit to a freestanding tub—consider hiring a licensed plumber.
