In the Market for a New Toilet? Here's What You Need to Know

Before you start shopping, check your current plumbing layout, as this will determine which toilet styles will fit without costly adjustments. Most Australian homes have either a bottom water inlet or back inlet system, and your choice of replacement toilet should match your existing setup unless you’re planning a full renovation and moving the plumbing. This helps avoid installation issues and unexpected expenses.

In Australia, toilets typically come in three main pan styles, S-trap, P-trap and skew trap, which refer to how wastewater exits the bowl. An S-trap leads down into the floor, a P-trap exits through the wall, and skew traps are angled and more common in older homes. Many modern toilets are universal and can suit both S-trap and P-trap, just be sure to match your pan type to avoid fit issues.

Water efficiency is increasingly important, and understanding WELS (Water Efficiency Labelling and Standards) ratings can save you money and help reduce environmental impact. In Australia, toilets with a 4-star WELS rating are the most water-efficient on the market, offering both full and half flush options that minimise water use without compromising performance.

Toilets come in different styles to suit both aesthetics and functional needs. Traditional back-to-wall toilets have a visible cistern and a classic look, while concealed or wall-hung toilets hide the cistern within the wall for a sleek, modern feel and can free up valuable floor space, ideal for smaller bathrooms or contemporary designs.

Beyond plumbing and style, consider toilet features that affect comfort and usability. Things like bowl shape, seat height, one-piece versus two-piece construction, and cleaning convenience all play a role in everyday satisfaction. Some modern toilets also offer enhanced hygiene options such as rimless bowls or slow-close seats, which make maintenance easier and can improve your bathroom experience overall.
