This calculator is a planning tool only. It does not provide a renovation quote or estimate the actual cost of labour, plumbing, electrical work, waterproofing, tiling or other construction work.

Every bathroom renovation is different. Use the result to help understand how your selections and contingency fit within your overall budget before obtaining detailed renovation quotes.

Plan Your Bathroom Renovation Budget

Working out how much you can afford to spend on a bathroom renovation is only the beginning. The next step is understanding how much of that budget may already be committed before construction even starts.

Use our free Bathroom Renovation Cost & Budget Calculator to enter your overall renovation budget, known fixture and finish costs and a contingency allowance. You'll then see how much of your budget remains for the renovation works.

What Should You Include in a Bathroom Renovation Budget?

A complete bathroom renovation budget may need to account for much more than the products you see in the finished room.

Depending on your project, costs can include:

  • demolition and waste removal

  • plumbing

  • electrical work

  • building and preparation work

  • waterproofing

  • tiling and tile installation

  • tiles

  • vanity and cabinetry

  • toilet, basin and tapware

  • shower fittings

  • bath

  • shower screen

  • mirrors and accessories

  • painting and finishing

  • unexpected work discovered during demolition

  • variations or upgrades during construction

Understanding where your money is going before work begins can help you make more informed decisions about where to spend, where to compromise and which selections may need to be reconsidered.

Don't Forget Your Contingency

Even a carefully planned renovation can uncover something unexpected once the existing bathroom is demolished.

A contingency gives you some breathing room if additional work is required rather than having every dollar of your available budget committed before construction begins.

The appropriate amount will depend on your project, property and circumstances, so the percentage in this calculator is adjustable.

A Budget Calculator Isn't a Renovation Quote

This calculator does not estimate what your bathroom renovation should cost.

Bathroom renovation costs vary considerably depending on the room, existing conditions, scope of work, layout changes, products, tiles, trades and level of finish.

Instead, this tool is designed to help you understand how your known selections and contingency fit within the total amount you're prepared to spend.

Once you have a clearer picture of your budget, you can have much more useful conversations with your renovator about what's realistically achievable.

Planning Your Bathroom Renovation?

Good renovation planning goes far beyond choosing beautiful tiles and tapware.

Understanding your budget, layout, selections, quote, allowances, timeline and potential variations before demolition begins can help you avoid rushed decisions once work is underway.

Own Your Reno was created to help Australian homeowners understand those decisions before spending tens of thousands of dollars renovating their home.
