How much does a bathroom renovation cost?

According to the Housing Industry Association (HIA), $19,553 was the average value of a bathroom renovation in 2018/2019. While this is a good guide, it’s important to remember that there is no single, standard cost for a bathroom renovation. 

As with any building project, the cost will be largely dependent on the size of your bathroom, scale of your renovation, materials chosen, fittings selected, permits (if required) and labour costs for your builder and their tradespeople. Due to these variables, a bathroom renovation can cost anywhere between $10,000 – $30,000 and beyond. 

To ensure you’re receiving the best possible quality and value for money, you’ll need to work with a highly experienced builder who can provide solutions to keep costs down and will ensure work is completed to an exceptional standard. This means you won’t need to pay for remedial renovations in a few years’ time.

How long does a bathroom renovation take?

Similarly, the timeframe for a bathroom renovation will differ drastically based on the scale and size of your bathroom renovation. The HIA’s research shows that it takes an average of 13 to 25 days to complete a full bathroom renovation. This factors in days where no one is on-site and things like waterproofing being left to set. 

Do bathroom renovations need council approval?

There are a few factors that will determine whether your project requires council approval. In Queensland, there are four categories of work that a bathroom renovation may fall into:

1. Permit Work
This type of project largely covers new bathrooms, including repurposing an existing room into a bathroom or an extension that will include a bathroom. This type of work will require council assessment and approval prior to work commencing and at least one inspection. 

2. Notifiable Work
This type of project covers work undertaken in existing buildings, including installation of new fixtures in existing bathrooms. This type of work can be carried out without council approval or inspections but must be performed by an appropriately licensed person who must notify the QBCC to advise when work is complete.

3. Minor Work
This includes installations of apparatus or removal of fixtures and fittings and must be carried out by a licensed person however does not require council approval. 

4. Unregulated Work
This type of project does not require a licenced person, council notification or council approval.

If you’re unsure, your council and chosen builder can help you determine if council approval is required and assist you with all the paperwork and documentation. Another reason to engage a highly experienced builder to help you through the process!
