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 inner rim channel under the bowl's lip. Traditional rimmed toilets have a concealed channel through which water flows during flushing, this channel is difficult to clean and can harbour bacteria and limescale. A rimless toilet flushes water directly across the entire bowl surface in a powerful swirling action, ensuring a thorough clean with every flush and leaving no hidden areas for bacteria to grow.

A behind-the-wall toilet (also called an in-wall or concealed cistern toilet) has the cistern hidden inside the wall cavity behind a finished panel, with only the toilet pan and a flush button plate visible on the wall face. The result is an extremely clean, minimal look with no exposed plumbing, one of the most popular choices in contemporary Australian bathroom design.

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, which can be removed without breaking tiles. The Geberit Sigma and similar systems have access panels specifically for this purpose. That said, it's important to use a reputable brand and have a qualified plumber install the frame correctly to avoid issues down the track.

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.
