Frequently Asked Questions
A floor waste is a compact, circular or square drain point set into the floor — typically 80mm to 115mm across. It is the standard drainage solution for most bathrooms and showers. A channel drain (also called a linear drain or strip drain) is a long, narrow drain that runs along one edge of the shower floor. Channel drains allow for a single-direction fall in the floor instead of a four-way fall to a centre point, which can simplify tiling and create a cleaner look — especially with large-format tiles.
A tile insert drain has a recessed frame that allows a piece of your floor tile to be dropped into the grate, making the drain blend in with the surrounding floor. The result is a near-invisible drain that maintains the visual flow of your tiling. Tile insert drains are available in both floor waste and channel drain formats and are popular in modern bathroom designs where a seamless floor finish is desired.
A wedge wire drain features a grate made from triangular-profile stainless steel bars (wedge wire) welded closely together. This design provides high water flow while preventing debris from entering the drain. Wedge wire grates are durable, easy to clean, and resistant to corrosion. They are a popular choice for both residential and commercial shower applications.
For floor wastes, the most common sizes are 80mm and 100mm — check your existing drain point or consult your plumber for the correct size. For channel drains, the length should match the width of your shower opening or the area you want to drain. Common channel lengths range from 600mm to 1200mm. Your plumber will also confirm the required outlet size and position to ensure proper connection to your existing waste plumbing.
Yes. Installing or replacing a shower waste involves connection to your drainage plumbing, which must be carried out by a licensed plumber in Australia. This includes floor wastes, channel drains, and any associated waterproofing work. Incorrect installation can lead to leaks, water damage, and failed waterproofing — which can be costly to repair. All drainage work must comply with Australian Standards (AS/NZS 3500).

Shower Wastes — Buying Guide
Shower wastes and floor drains may not be the most glamorous part of a bathroom renovation, but they play a critical role in keeping your bathroom functional and water-damage free. The right drain not only handles water flow efficiently but can also complement the look of your shower floor — especially with modern options like tile insert and wedge wire designs.
Floor Wastes
A floor waste is the traditional circular or square drain point set into the shower or bathroom floor. They are compact, reliable, and suit most standard shower setups. Floor wastes require the shower floor to be sloped on all sides towards the drain point (a four-way fall). They are available in a range of finishes to match your bathroom tapware and accessories.
Channel Drains
A channel drain (linear drain) runs along one edge of the shower floor, collecting water across its full length. The main advantage is that the floor only needs to slope in one direction, which makes tiling simpler — particularly with large-format tiles where multiple fall directions can cause lippage. Channel drains also give a modern, streamlined look to the shower floor.
Grate Styles
There are two main grate styles to choose from. Wedge wire grates use stainless steel bars welded together for a durable, high-flow design that is easy to clean. Tile insert grates have a recessed frame that holds a piece of your floor tile, creating a near-invisible drain that blends seamlessly with the floor. Both are available for floor wastes and channel drains.
Installation
All shower waste installation must be carried out by a licensed plumber. The drain connects to your building's waste plumbing and must be properly waterproofed to prevent leaks into the floor structure. Your plumber will confirm the correct drain size, outlet position, and fall requirements for your specific shower layout. All work must comply with Australian Standards (AS/NZS 3500).
