How Much Does a Bathroom Renovation Cost?

In 2025, a full bathroom renovation in Australia typically costs between $15,000 and $40,000, with most Newcastle homeowners spending around $25,000–$30,000 for a quality mid-range upgrade. Several factors influence where your project will sit within that range, including the size of the space, the quality of fixtures and finishes, and whether you’re making layout changes or keeping plumbing in place.

This article focuses on full bathroom renovations — our specialty — rather than minor refreshes like repainting or replacing a few fixtures. Whether you’re working with a cosy 1 m × 2 m ensuite or a spacious 3 m × 3 m bathroom, we’ll walk you through what impacts cost and how to plan for your ideal space.

• Standard – $25,000 to $35,000: Minimal tile designs, single vanity, chrome tapware, inset bath, and twin rail shower.
• Mid-Range – $35,000 to $45,000: One feature tile, stone basin and vanity, additional tapware, and feature door.
• High-End – $45,000 to $55,000: Bespoke feature tiles, custom vanity, 5+ water points, and automated lighting.
• Luxury – $55,000 to $120,000+: Underfloor heating, strip lighting, skylights, high-end fixtures, and complex designs.

Note that these estimates apply to complete rebuilds, where the existing bathroom is completely gutted back to the framework. The space is then redesigned and rebuilt according to your specified budget and the details outlined in your contract.

The Key Elements of a Bathroom Renovation Quote

Explore our expert insights and practical tips to help you confidently prepare, plan, and carry out your bathroom renovation. This essential guide helps you clearly communicate your vision and ensures every detail is accounted for — from the initial design to the final finishing touches — so you can avoid unexpected surprises and stay in control throughout the project.

Banana Bathrooms Quote Checklist

1. Does your quote include custom Shower screens, and is the cost of coloured clips included? We provide custom-sized shower screens and include the cost of coloured clips (for example, if you have black tapware, you will want black clips on the shower)
2. Are they purchasing building insurance on your behalf? 
3. Is the cost of any remediation work to other rooms outside of the bathroom included? For example, if you have opted to move a doorway, has the quote included the cost of repairing it in the hallway or externally, where the previous door used to be?
4. If you are updating windows, does the cost include both the installation and supply of the windows?
5. Does the quote specify how high the tiling will go? 
6. Does the quote include PC items? Does the PC allowance quoted for each item allow you to purchase the desired quality level?
7. Does the quote include a 3D render? 
8. Does the quote include asbestos testing and removal if necessary? What is the company’s policy if they find asbestos?
9. Does the quote include painting or wallpapering?  

Notes:

• Always get multiple quotes to compare prices and services.
• Check references and past work of contractors. (check out our 50+ Google reviews here)
• Ensure all quotes include the same scope of work for accurate comparison.
• Verify the licensing of tradespeople.
• Ensure that they have proper insurance coverage for working on your property.

 

This checklist covers the key components of a bathroom renovation project. Discussing every item with your contractor is essential to ensure everything is accounted for and to establish clear expectations for the project’s completion.

Summary

Shelley, our Bathroom Designer, advises that when working out how much a Bathroom Renovation costs, set aside 5 to 10% of your home’s value for renovations, especially for key areas like the kitchen, bathroom, and laundry.

When planning a renovation, it’s essential to prioritise long-term value over immediate savings. Additionally, upgrading areas such as the kitchen and bathrooms can significantly increase your home’s market value—potentially by up to $250,000—if you’re considering selling it in the future. 

While some designs may become outdated after a decade, it’s crucial to carefully consider the style and consult with our interior designers. This will allow you to enjoy your newly renovated bathroom in the short term and capitalise on your investment when it’s time to sell.

At Banana Bathrooms, we do it all, so you don’t have to lift a finger if you don’t want to! From demolition to completion, we will be there every step of the way. We are as transparent as they come when it comes to our quotes. We won’t sting you later with any hidden costs. Our quotes include everything; what you see is what you get.
