Choosing a toilet may appear simple but there are many factors involved in selecting a model and in toilet installation. There are many different types of toilets to choose from, including the size, shape and function. It is important to select the best one to meet functional needs and which looks the best for its location. Optimised Plumbing Services has been installing toilets in Sydney for over 20 years, therefore, we understand how to select the right toilet to install. 

There are four main types of toilets to choose from, including close-coupled, back to wall, wall hung and wall faced. There are positives and negatives with each toilet, furthermore, there are other factors to examine. Such as ease of cleaning, plumbing, the location and the seat, toilet installation has many different considerations involved in it.

Close-Coupled Toilets

The most common type of toilet installed is the close-coupled toilet due to their simplicity and affordability. This type of toilet has the cistern located behind the bowl of the toilet to then join pan which hides the flush pipe. Moreover, this toilet has room behind the toilet, while also the flush button situated on the cistern at the top. 

  • Positives – the close-coupled toilet is the most common due to being cost-effective, easy to repair and offers a simple design. Furthermore, these toilets require minimal labour involved in the installation, similar, are easy to plan/ install into an area. In particular, renovations appreciate this toilet type because of it not needing the tiles or plumbing to be altered.
  • Negatives – the space which is between the toilet and the wall can mean that cleaning it can be a hassle. Furthermore, due to the simple design, it may not be chosen because it does not fit well with modern or streamline bathroom designs.

Back To Wall Toilets

As the name might suggest, back to wall toilets are situated flush against the wall. The toilet pan has the back of the cistern situated above it, furthermore, the whole entire unit is placed against the wall. As a result, there is no gap behind the toilet, as a close-coupled toilet has. 

  • Positives: the design which this toilet brings is modern due to being a single unit against the wall. Moreover, being flush against the wall means that additional cleaning behind the toilet is not present. These toilets are simple to repair, while also offering flexible installation options of the P and S trap. 
  • Negatives: a main downside with this toilet is that it may not install correctly with current/ existing plumbing. This chance of it being uninstallable increases depending on the age or type of previous toilet present.

Wall Hung Toilets

These toilets are mounted onto the wall offering a spacious and modern design, increasing in its popularity. Being mounted onto the wall, there is a gap beneath the toilet, meaning there is no toilet base. Also, the cistern is located within the wall along with an inbuilt frame.

  • Positives: the present gap between the floor and the toilet offers more space, allowing an open-bathroom aesthetic. Additionally, the pan has the flexibility to where it can be installed meaning it can be adjusted to different heights. The cistern in the wall means that it is much quieter, and also the toilet is overall easier to clean.   
  • Negatives: there is much more planning involved in this type of toilet due to the in-wall frame and cistern. Likewise, the actual toilet is more expensive than others, along with the installation costs are also higher in pricing.

Wall Faced Toilets

These types of toilets are installed on the floor, similar to the back to wall toilet. However, this design of toilet has the cistern within the wall with no gap between the pan and the floor. With this plumbing, the waste lines and plumbing need to be in the wall flowing straight for the hidden aesthetic. 

  • Positives: increasing in its popularity, these toilets are an alternative to S-trap installations. This is because of their floor-mounted designs allowing the s-tap to rather go through the wall but through the floor. Moreover, these toilets are extremely easy to clean, due to many parts of the toilet being hidden and there also being no gap. Furthermore, the toilet is much more quieter, as well as, is easier to repair though using the flush plate. 
  • Negatives: the toilet includes a more lengthy and costly installation compared to other toilets. Also, if the chance of major repairs needing doing, accessing the cistern will make it more difficult and expensive.

Other Factors with Toilet Installation

Some other important considerations which should be thought out before selecting the right toilet type are:

  • Ease of Cleaning – a toilet can be designed to clean/ flush the whole bowl which can be preferred. Additionally, the size/ shape of the toilet, as well as its location, need to be considered if it will be hard to clean it. 
  • Plumbing – if existing plumbing is present then knowing if the new toilet can properly be installed with that plumbing is important. Especially if there is an in-wall cistern, or if the toilet will be installed in/ on the wall the plumbing must be correct. 
  • The Location – when a new toilet is wanted to be installed it must be measured, therefore must fit into the new place.  The wast outlet’s distance between the wall is important to know, as well as S trap distances and alike. Overall, knowing the dimensions of the toilet and existing place which it would be installed in is important. 
  • The Seat – soft-closing toilet seats should be considered when purchasing toilets due to their functional benefits. There is much less noise created when the seat is lifted down which is always a positive. Because it slowly goes down it is safer for children, additionally, the seat is easy to remove for maintenance purposes.
