Jim The Bathroom Guy

Bathroom renovations can get expensive very quickly. I’ve seen jobs that should’ve cost $15k end up closer to $30k, all because of a few early decisions that weren’t thought through properly.

The good news is, saving money on a bathroom renovation isn’t about cutting corners. It’s about knowing where to spend, where to hold back, and avoiding the mistakes that blow budgets out.

Everything in this guide is based on real bathrooms I’ve worked on and the cost issues I see all the time. If you get these right, you can save thousands without sacrificing the end result.

Below are my tried-and-tested ways to save money on your bathroom renovation, based on over 20 years of hands-on renovation experience.

What a Bathroom Renovation Costs in Australia

If you’re planning a bathroom renovation in Australia, one of the first questions is: how much will it actually cost? Here’s a realistic guide based on what I’m seeing across real projects in 2026 heading into 2027

Small Bathroom Renovation Costs $20,000 – $29,995

Includes keeping basic layouts, standard tile sizes (no larger than 600 x 600), mid-range fixtures, and professional fully managed project. Ideal for a simple shower, toilet, and vanity setup, with minimal plumbing changes (think changing mixers standard, replacing galvanised plumbing or adding a toilet non-standard)

Mid‑Range Bathroom Renovation Costs $29,000 – $38,000

This includes everything above but now we are talking a bath, added bricked shelving (niche or half wall) most likely a custom screen. Perfect for flexibility on layout. This costing is really for a slightly larger room, but more of what you want.

High‑End Bathroom Renovation Costs $35,000+

For me these types of renovation can be anything but really are for what I call 4 part rooms, bathrooms with a vanity, toilet, bath and shower that is stand alone. These start higher due to the cost of materials and go from there.

These ranges cover standard layouts, quality fixtures, and professional workmanship. Costs can shift depending on factors like moving plumbing, custom cabinetry, or premium finishes. Focusing your budget on the essentials—layout, waterproofing, and reliable trades—will help you save money without cutting corners.

“Cost ranges can vary by city because of labour and material differences — typically, Perth, Adelaide can be a little bit cheaper than Sydney and Melbourne but in this current client the demand is high and the supply is low.

Wrapping Up Your Bathroom Renovation Journey

Renovating a bathroom doesn’t have to be stressful or expensive—if you plan carefully and focus on the right elements. By understanding costs, choosing the right layout, and prioritising quality where it matters, you can save money and create a space that looks and feels great for years to come.
