So, we are a bathroom plumbing company in Sydney that can convert your existing toilet to be a bidet – sounds simple right? Well how simple this type of toilet conversion in Sydney is will depend on the products being changed. If you can choose two items that share similar dimensions for the water inlet and sewer pipe outlet then the task can be relatively straight forward.

For the home owners of this house in Sydney they wanted to change the existing toilet bowel to have a brand new bidet installed. Not just any boring, plain bidet mind you, but an extremely feature rich model from Arcisan. The biggest challenge with adapting existing plumbing in Australia to products that come from Europe or Japan is they have different placement of their inlet and outlet connections. If there are big differences in where the plumbing needs to be placed then potentially the pipes need to be moved which may require pulling tiles off the wall or cutting into the floor. 

For this conversion we had to first remove the old toilet to measure the hidden drainage/water plumbing to then ensure the new washer / bidet toilet suit could fit in its place. Fortunately the Arcisan unit could fit, but still needed a bit of plumbing and electrical work to get it installed correctly. Fortunately most of the existing placement of the plumbing was ok to work with, we had to slightly adjust the sewer line though.

The other aspect a lot of people don’t consider when getting a bidet installed is that you need electrical wiring to operate the washer if it is powered by a motor and/or other control options. What made all of this quite easy to do is the existing toilet cistern was concealed behind a vanity unit panel so most of our work could be done without breaking tiles or cutting into the floor or wall. 

The cost to buy this bidet from Arcisan is between $3,000 and $4,000 inc gst depending on which retailer you purchase from.

The installation cost plus the bidet will typically vary between $7,000 and $10,000 depending on the scope of work required to get it to fit into the existing bathroom.

Can you install a smart bidet in Sydney on your own?

For a smart bidet that requires custom connection to the existing plumbing, electrical work or even minor bathroom renovations to the floor or wall you cannot generally do it yourself. If it is a bidet that sits on top of your existing toilet seat then some models are great for DIY. Using a bidet has lots of benefits as they are generally considered to be more hygienic and better for personal hygiene than using only a standard toilet. Here are 10 reasons why:

  1. A bidet can help to clean the anus more effectively than toilet paper alone.
  2. A bidet can help to prevent hemorrhoids and anal fissures caused by excessive wiping with toilet paper.
  3. Using one can help to prevent urinary tract infections by reducing bacteria in the urinary tract.
  4. It can reduce the amount of toilet paper used, which is better for the environment and can save money.
  5. It is a great way to reduce the spread of germs and bacteria in the bathroom.
  6. You will feel refreshed and clean feeling after using the toilet.
  7. A bidet can be helpful for people with mobility issues or disabilities that make it difficult to clean themselves with toilet paper.
  8. They will generally help to reduce odors in the bathroom.
  9. This type of bathroom item can be used to clean up after menstruation, which can make it more comfortable and hygienic.
  10. It is a great product for people with certain medical conditions such as colitis, inflammatory bowel disease, or hemorrhoids.

There are pros and cons to both separate toilet and bidet units and combined units.

Pros of separate units:

  • They are generally more customizable and offer more options for different types and styles of toilets and bidets.
  • If one component breaks or needs to be replaced, only that component needs to be replaced rather than the entire unit.

Pros of combined units:

  • They save space and are a good option for smaller bathrooms.
  • They are more aesthetically pleasing and can have a more cohesive look in the bathroom.


Cons of separate units:

  • They can take up more space in the bathroom.
  • They may be more expensive to purchase and install.

Cons of combined units:

  • If one component breaks, the entire unit must be replaced.
  • Limited options available in terms of style and features.

Ultimately, it depends on the individual’s needs, preferences and bathroom space.

What is the best smart bidet to get installed in Sydney?

Look we are not bidet experts and there are thousands of models available on the market, but have a look at all the things this thing can do.

Combining the aesthetics of a rimless toilet pan and the convenient cleaning functions of bidets, the Arcisan Neion square wall faced Intelligent Toilet with remote and in wall cistern is the perfect addition to your contemporary bathroom or ensuite. The Arcisan Neion Intelligent Toilet offers a host of smart technologies, such as gender specific functions, massage, air temperature controls, and variable pressure levels. 

Most of these functions are accessible through the included user-centric remote controller. Coated with a special glaze that incorporates nano technology, the Arcisan Neion’s ceramic surface allows the pan to stay cleaner for longer. In addition, the nozzle cleans itself before and after every use, while the tank runs a self-cleaning mode if left idle for a set period. Built with practicality in mind, the Arcisan Neion can be mounted without the need for additional valves. It also features a wall-hung design, so you can install it without monopolising the bathroom area. Notable for its compact and streamlined aesthetic, the Arcisan Neion makes a great focal point for the design-conscious bathroom.

Apart from the hygiene benefits, a bidet can reduce the amount of toilet paper being used in a house:

  1. Bidet: The most effective way to reduce toilet paper usage is by using a bidet. A bidet is a plumbing fixture or type of seat that sprays water to clean the user’s anus and genitals after using the toilet.

  2. Dual-flush toilet: Dual-flush toilets have two buttons or levers to flush the toilet, one for liquid waste and one for solid waste. This can help save water and reduce the amount of toilet paper needed to clean the bowl.

  3. Low-flow toilet: Low-flow toilets use less water per flush, which can help reduce the amount of toilet paper needed to clean the bowl.

  4. Composting toilet: A composting toilet is a type of toilet that uses natural processes to break down and recycle human waste. These toilets do not require the use of water or toilet paper.

  5. Education and awareness: Teaching and reminding the family members to use only what they need, and also not to flush anything other than human waste and toilet paper can also help in reducing the usage of toilet paper.

  6. Reusable wipes: Investing in reusable wipes or cloths can be used as an alternative to toilet paper, which can be washed and reused multiple times.

It’s important to note that some of these options may not be suitable for everyone, and it’s essential to consider the cost, the availability of resources, and the overall feasibility before making a decision.
