Advice for choosing a toilet

Traditionally all toilet pans only sat on the floor and did not touch the wall and the cisterns did not touch the pan but were higher up on the wall and joined by a pipe.  This is called a Connector Suite.

Modern toilet options

Back to wall: This is where the s-bend pipe is fully enclosed in the toilet pan so it isn’t visible.  The foot of the toilet goes all the way back to the wall and touches the wall.  Having flatter surfaces and no parts to reach to around the back of the toilet makes them easier to clean and looks tidier.

Close coupled: This means that the cistern is mounted on top of the toilet pan with no visible pipe. They are generally more aesthetically pleasing. As there is a lower cistern, some toilets do not flush as well as a toilet with a higher cistern.

Other toilet advice

Flushing: Traditionally the cisterns on toilets used to be a lot higher than modern toilets.  One of the advantages of the higher cistern was that the water was flushing from a higher height so it had more pressure by the time it hit the toilet pan.  New toilets also have less water capacity to save on water consumption.  An older style cistern may have had 9 litres of water, but a newer cistern may have a 6 litre full flush and a 3 litre half flush.  It is common to find that a newer toilet does not flush as well as an older style toilet.  I have heard them being described as a “flush and brush” toilet.  Some models are still available with the higher cisterns but they don’t look quite as modern.

Toilet set out: It is a lot easier and more efficient if you can get a new toilet that has the same waste connections as your old one. If your waste pipe goes through the floor, it is an S pan.  If it goes through the wall it is a P pan.  The set out is the distance from the existing finished wall (measure from the wall, not the skirting) for a S pan, or from the floor for a P pan to the centre of the waste pipe.  When you buy your new toilet it will be helpful to have this measurement.  Try to buy a new toilet that has a set out less than 40mm different than your existing one.  If it is more than 40mm different, it will usually cost about $250 to change a concrete floor or about $150 to change a wooden floor to suit your new toilet.
