A wall faced toilet (also called a close-coupled toilet suite) features a cistern that sits directly on top of and flush against the rear of the toilet pan, creating a seamless back panel. The back of the unit sits flat against the wall, giving a cleaner look than older exposed-plumbing models. Wall faced toilets are the most common toilet suite type sold in Australia and suit both modern and traditional bathrooms.

A rimless toilet has no enclosed channel under the bowl's lip. Traditional rimmed toilets have a hidden channel that water flows through during flushing, this is hard to clean and can harbour bacteria and limescale. A rimless bowl flushes water directly across the surface instead, making it easier to keep hygienic.

A wall-faced (close-coupled) toilet has the cistern sitting on top of and against the pan, with both visible. A behind-the-wall (in-wall/concealed) toilet hides the cistern inside the wall cavity, leaving only the pan and a flush plate visible. A wall-hung toilet goes further again, mounting the pan itself off the floor for a fully floating look.

The cistern is housed in a pre-fabricated in-wall frame (called a carrier frame or in-wall system), which is installed by a plumber before the wall is tiled or sheeted. The flush button on the wall face connects via a pneumatic or mechanical system to the cistern inside the wall. Brands like Geberit are the industry standard for in-wall frames in Australia, known for their reliability and long service life.

Modern in-wall cistern systems are designed for ease of maintenance. Most allow access to the cistern via the flush plate itself, which can be removed without breaking tiles, the Geberit Sigma and similar systems include access panels specifically for this purpose.

A smart toilet combines a toilet and bidet in one unit, typically featuring a heated seat, warm water rear wash, front wash, air drying, deodoriser, and often auto-open/close lid, nightlight, and remote or touch control. Some models include self-cleaning nozzles, eco flush modes, and Bluetooth connectivity. Smart toilets are increasingly popular in Australian bathrooms as awareness of bidet hygiene benefits grows.

A bidet seat (or bidet toilet seat) is a retrofit unit that replaces your existing toilet seat and adds wash functions, whereas a smart toilet is a complete, fully integrated toilet suite with all features built in. A bidet seat is a more cost-effective upgrade if your existing toilet is in good condition. A full smart toilet suite offers a more seamless design and typically a wider range of features.
