More info on toilets

Before we start, some technical stuff

When buying a toilet, you need to be able to answer the following questions:

  • Do I need an S-Trap or a P-Trap?
  • What is the setout?
  • Will I need a rear or bottom entry?

S-Trap or P-Trap, what's the difference?

The "trap" is the bend in the pipe where the waste goes out of the toilet. It retains some water after flushing causing a seal and preventing sewer gases from entering the building.

An S-trap exits at the bottom of the toilet and is designed to outlet directly through the floor.

Toilet S Trap

A P-trap exits at the back of the toilet and is designed to outlet through a wall.

Toilet P Trap

Setout

The Setout refers to the distance to the centre of the waste outlet.  For an S-Trap, the setout is the measurement from the finished wall to the centre of the waste pipe in the floor (modern standards are between 140mm and 165mm). For a P-Trap, the setout is the measurement from the finished floor to the centre of the waste outlet in the wall (the standard is 185mm).

If you are replacing an existing toilet and do not want to change the plumbing, you will need to ensure that your new toilet will fit the existing plumbing.

If you have a P Trap toilet you should not be too restricted as most P Traps have a standard set out. However, if you have an S trap toilet, you will need to make sure that you have the measurement from the wall to the centre of the trap before you purchase a replacement toilet.

Rear Entry and Bottom Entry (Cisterns)

(Rear/Back or Bottom Entry Inlet)

The entry (or inlet) is where the water enters the toilet cistern. A bottom entry toilet has a tap on the wall under the cistern, on either the right or left hand side of the toilet, and it connects to the bottom of the cistern. A rear entry toilet connects inside the cistern.

As a general rule, changing the location of the inlet is not as difficult as changing the location of the trap. Bathroomware House recommends that you check your individual situation with your qualified plumber before purchasing your toilet.

Toilet Suites

There are hundreds of toilet suites available in the market. Other than looks, factors such as size, inlet position, how well it functions and water efficiency should play into your decision.

When choosing a toilet suite for your bathroom, you must ensure that it carries a W.E.L.S. rating to comply with government regulations. For more information about W.E.L.S. rating you can visit the Australian government website:

All that said, if you are remodelling your bathroom here are the different toilet types you can consider.

Wall Facing Toilet Suites

Back to Wall Toilet Pans

Back to wall pans are a clever way to maximise space in the bathroom by concealing the cistern within a piece of furniture or stud wall.  The toilet type offers a simple uncluttered bathroom finish that is easy to maintain for residential or commercial use.

Close Coupled Toilet Suites

Close coupled toilet suites deliver modern looks and easy-clean style at an affordable price.

Link Toilet Suites

Most suites come with adjustable link and seat, floor waste outlet and feature a dual flush system for maximum water economy.
