How to choose Bathroom Floor Wastes

As per the National Construction Code (NCC) and Australian Standard AS 3740, a floor waste is required in shower areas and in rooms where water may escape onto the floor — such as bathrooms with unenclosed showers or laundries without built-in overflow protection. A floor waste is also required where a wet area is located directly above another unit or public space in multi-storey buildings. However, a floor waste is not mandatory in every bathroom or laundry, especially in single-storey homes with enclosed fixtures. If your renovation includes an open shower or upper-floor wet area, floor wastes are required and should be planned accordingly.

Thankfully, floor wastes have come a long way in recent times and can now make a space look more modern. Knowing which floor wastes to choose comes down to the application and your style preference.

Floor Waste FAQs

A floor waste is a grated drain installed in the floor to collect and remove water.
It connects to the home’s plumbing system and helps prevent water from pooling or flooding. In bathrooms, laundries, and wet areas, it also acts as a secondary drainage point in case of overflow.

A channel drain is a long, narrow drainage system used to collect surface water across a wider area.
It’s also known as a linear drain and is commonly used in bathrooms with open showers or in outdoor areas like patios and pool zones. In bathrooms, channel drains can replace traditional centre floor wastes for a cleaner look.

A floor waste is only required in a bathroom if there’s a risk of water escaping onto the floor.
In most cases, a floor waste is mandatory if the shower is unenclosed or if the bathroom is located above another dwelling or public space (e.g. in a two-storey home or apartment). If the shower is fully enclosed and all fixtures are drained independently, a floor waste may not be required under the National Construction Code (NCC) and AS 3740.

Even when not mandatory, many WA homeowners include a floor waste to reduce the risk of water damage and meet best practice for wet areas.

A floor waste is not always required in a laundry under the NCC, but it is strongly recommended in most cases.
If the laundry is located on an upper floor or directly above another unit or living space, a floor waste is required under the National Construction Code. In ground-floor laundries, a floor waste may not be mandatory — but if there’s any risk of overflow or water spillage (such as from a washing machine without built-in overflow protection), it’s best practice to include one.

For most Perth renovations and new builds, a floor waste is included for peace of mind and compliance.

No, a toilet does not require a separate floor waste.
Toilets are self-contained fixtures with a direct sewer connection. However, if the toilet is located within a bathroom, the bathroom itself may still require a floor waste depending on layout and drainage design.

No, 40mm waste is not sufficient for showers in WA.
According to AS/NZS 3500, showers must be connected to a minimum 50mm diameter waste pipe to meet code. Using a 40mm waste may lead to slow drainage or non-compliance.

A floor trap is the plumbing fitting under the floor that connects the waste outlet to the drainage system and contains water to stop smells.
A floor waste refers to the visible grate or drain in the floor. The trap is hidden below; the waste is what you see on the surface.

The terms are often used interchangeably, but technically:

  • Floor waste refers to the general outlet in the floor that provides overflow drainage.
  • Floor drain usually refers to the full unit including the grate and the trap underneath.

In Australia, “floor waste” is the more common term in residential bathrooms and laundries.
