Shower drains come in more shapes, sizes, and finishes than most Sydney homeowners expect. The traditional round or square grate you see in the centre of your shower floor is just one option—modern bathrooms now feature long, narrow linear drains along the edges, tile-in designs that blend seamlessly into the floor, and decorative covers in brushed nickel, matte black, or even custom patterns. Understanding what does a shower drain look like, how it functions, and which style suits your bathroom helps you make informed decisions during renovations or repairs—and ensures your plumbing meets Australian Standards for water drainage and waterproofing.
In this guide, we’ll walk you through the main types of shower drains, the key components that make them work, the materials and finishes available, and the warning signs that tell you it’s time to replace or upgrade. You’ll also learn why professional installation matters, how to maintain your drain, and when to call in a licensed Sydney plumber for same-day service.
Key Takeaways
- Shower drains include point drains (round or square grates in the centre), linear drains (long narrow slots along edges), and tile-in drains that sit flush with your floor.
- Every drain has a body, trap, grate or cover, and waterproofing flange—each part plays a role in keeping water flowing and your bathroom dry.
- Materials range from stainless steel and brass to PVC and ABS plastic, with finishes like chrome, brushed nickel, and matte black to suit any design.
- Proper slope, waterproofing, and compliance with AS/NZS 3500 are critical to prevent leaks, mould, and structural damage.
- Professional installation ensures your drain is correctly sized, positioned, and sealed—protecting your investment and meeting code requirements.
What Does a Shower Drain Look Like in Traditional Point Drains?
Point drains are the most common type you’ll see in Sydney homes. They sit in the centre of the shower floor, usually round or square, with a grate that allows water to funnel down through the drain body and into the waste pipe below. The grate itself can be a simple grid pattern, a decorative medallion, or a low-profile design that sits nearly flush with the tiles.
The drain body—the part you don’t see—extends beneath the shower pan or tile base and connects to your home’s plumbing stack. It includes a built-in trap (a curved section of pipe that holds a small amount of water to block sewer gases) and a bonding flange that integrates with your waterproof membrane. This flange is crucial: it creates a watertight seal between the drain and the surrounding substrate, preventing water from seeping into the subfloor or wall cavities.
Point drains work well in most shower configurations, but they do require the entire floor to slope toward the centre. That means tiles are laid at a gradient—typically 1:100 or 1:80 under Australian Standards—to guide water to the drain. If the slope is incorrect, water pools, drainage slows, and you risk mould growth or slip hazards.
What Does a Linear Shower Drain Look Like and How Does It Work?
Linear drains are long, narrow channels that run along one edge of the shower—often against the back wall or at the threshold of a curbless, walk-in design. Instead of a single round grate, you’ll see a slot or series of openings that span anywhere from 600 mm to 1,800 mm in length. The visible cover can be a simple stainless-steel grate, a tile-in channel that matches your floor, or a decorative pattern that adds a design feature to your bathroom.
The key advantage of a linear drain is the simplified floor slope: water only needs to flow in one direction, toward the channel, rather than converging on a central point. This makes it easier to lay large-format tiles, create a truly level threshold for accessibility, or design a wet-room aesthetic where the shower blends seamlessly into the rest of the bathroom. Linear drains are popular in modern renovations across Sydney’s Inner West and Eastern Suburbs, where homeowners want clean lines and barrier-free access.
Beneath the cover, the linear drain body is a shallow, elongated trough that collects water and directs it to an outlet pipe, usually positioned at one end. The trap is integrated into the body or installed downstream, depending on the model. Installation requires precise positioning and waterproofing—the bonding flange must be sealed to the membrane, and the surrounding floor must slope correctly to avoid standing water.
Key Components of Any Shower Drain
No matter the style, every shower drain shares a set of core components that work together to move water out of your bathroom and keep your home dry. Understanding these parts helps you spot problems early and communicate clearly with your plumber when repairs or upgrades are needed.
1. Drain Body
The drain body is the main housing that sits beneath your shower floor. It connects the grate at the surface to the waste pipe below and includes mounting points for the waterproof membrane. In point drains, the body is typically round or square with a threaded collar. In linear drains, it’s a long channel with an outlet at one end.
2. Trap
The trap is a U-shaped or P-shaped section of pipe that holds a small pool of water. This water seal blocks sewer gases from rising back up through the drain and into your bathroom. Some modern drains have the trap built into the body; others connect to a separate trap installed in the floor cavity or wall.
3. Grate or Cover
The grate is the visible part you stand on. It can be a perforated metal grid, a decorative tile-in frame, or a snap-in cover that hides the drain opening. Grates are designed to let water through while catching hair and debris—though they still need regular cleaning to prevent clogs.
4. Bonding Flange
The bonding flange is a flat ring or lip around the top of the drain body. Your waterproof membrane (a sheet or liquid-applied barrier) bonds to this flange, creating a continuous seal that prevents water from leaking into the substrate. Proper bonding is non-negotiable under AS/NZS 3740 (Waterproofing of Domestic Wet Areas).
5. Outlet Connection
The outlet is where the drain body connects to your home’s waste pipe. It may be a threaded fitting, a solvent-weld socket, or a compression joint, depending on the pipe material (PVC, copper, or cast iron). The connection must be watertight and compliant with AS/NZS 3500.2 (Plumbing and Drainage—Sanitary Plumbing and Drainage).
Materials and Finishes: What Shower Drains Are Made From
Shower drains are manufactured from a range of materials, each chosen for durability, corrosion resistance, and compatibility with your plumbing system. The visible grate and the hidden body may use different materials, so it’s worth knowing what you’re installing—or what’s already under your tiles.
| Material | Common Use | Pros | Cons |
|---|---|---|---|
| Stainless Steel | Grates, drain bodies, linear channels | Corrosion-resistant, strong, modern look | Higher cost, can show water spots |
| Brass | Drain bodies, decorative grates | Durable, accepts plating (chrome, nickel) | Can tarnish if not plated |
| PVC | Drain bodies, outlet pipes | Lightweight, affordable, easy to install | Not suitable for very hot water, can crack over time |
| ABS Plastic | Drain bodies, traps | Impact-resistant, good chemical resistance | Less common in Australia, can degrade in UV |
Finishes for grates and covers include polished chrome, brushed nickel, matte black, oil-rubbed bronze, and even gold or copper tones. Some manufacturers offer powder-coated colours or tile-in frames that let you insert a piece of your floor tile directly into the drain cover, creating an almost invisible finish. The choice of finish should match your tapware, showerhead, and overall bathroom style—but remember that the drain body and trap materials matter more for long-term performance.
How to Identify the Type of Shower Drain in Your Bathroom
Knowing what kind of shower drain you have makes renovations, replacements, and drain troubleshooting much easier. In most bathrooms, you can identify the drain type by checking the grate style, where it sits on the shower floor, and how the tiles slope toward it. Use the checklist below to narrow it down quickly before you remove tiles or buy new fittings.
- Check the Grate Shape and Location: A round or square grate in the centre of the shower floor usually indicates a traditional point drain. A long, narrow slot or channel along one edge points to a linear drain. If the grate sits flush with the tiles and you can barely see the edges, you likely have a tile-in or low-profile design.
- Measure the Floor Slope: Point drains require the floor to slope toward the centre from all sides. Linear drains need a single-direction slope toward the channel. If your floor feels level or slopes toward a wall without a visible drain, you may have an older design or a drainage issue that needs attention.
- Look for a Removable Cover:
Many modern drains have snap-in or screw-in covers that you can lift out to access the trap and clean hair or debris. If your grate doesn’t budge, it may be grouted in place or part of an older fixed design. - Inspect the Waterproofing Flange: If you’re doing a renovation and the tiles are already removed, look for the bonding flange around the drain body. A visible flange with a membrane bonded to it confirms a code-compliant, waterproofed installation. No flange or a loose membrane suggests the drain may not meet current standards.
- Test the Drainage Speed: Turn on the shower and watch how quickly water drains. If it pools or drains slowly even when the grate is clean, the trap may be partially blocked, the slope may be incorrect, or the drain body may be undersized for your shower flow rate.
Identifying your drain type early helps you plan compatible fittings, ensure proper floor grading, and avoid expensive corrections later. It also allows you to confirm whether your current installation meets modern waterproofing standards. If drainage problems persist, a professional inspection can determine whether the issue lies in the slope, trap, or pipework.
Compliance, Standards, and Why They Matter
In New South Wales, all plumbing work—including shower drain installation—must comply with the Plumbing Code of Australia (PCA) and the relevant Australian Standards. AS/NZS 3500.2 covers sanitary plumbing and drainage, specifying minimum trap sizes, vent requirements, and pipe materials. AS/NZS 3740 sets out the waterproofing requirements for wet areas, including how the membrane must bond to the drain flange and extend up the walls.
These standards exist to protect your health, safety, and property. A properly trapped drain prevents sewer gases from entering your home. A correctly bonded waterproof membrane stops water from leaking into the building structure, where it can cause rot, mould, and expensive damage. And a compliant installation ensures your work is covered by insurance and meets council requirements if you ever sell or refinance your home.

Every job is completed to Australian Standards, documented with photos and compliance records, and backed by our lifetime labour warranty. When you choose a licensed professional, you’re not just paying for the installation—you’re investing in peace of mind.
Why Professional Installation Matters for Shower Drains
Installing a shower drain isn’t a simple drop-in job. It requires precise coordination between the plumber, waterproofer, and tiler—each trade relying on the others to get their part right. A drain that’s positioned too high or too low, a membrane that’s not bonded correctly, or a floor slope that’s off by even a few millimetres can lead to leaks, mould, and expensive rework.
Under AS/NZS 3500.2, shower drains must be installed by a licensed plumber and comply with minimum trap seal depths, vent requirements, and waste pipe sizing. The waterproofing must meet AS/NZS 3740, which specifies how the membrane bonds to the drain flange and extends up the walls. Cutting corners or relying on unlicensed installers puts your home at risk—and may void your insurance if a leak causes damage.
Our team at Antons Plumbing & Gas handles every aspect of drain installation: selecting the right type and size for your shower, positioning the body to match your tile layout, bonding the waterproof membrane, and testing the drainage before the tiler finishes the floor.
