How much should you spend on a bathroom renovation?

Remember the time when your bathroom was brand new? Your sanctuary, your private escape. It’s where you wind down, relax in your tub with a glass of wine on the one hand, and a loofah on the other—clean, pristine.

Now, it’s leaky showerheads, sewer smells, the moulds, or poor ventilation, among other things. You’re in dire need of a bathroom makeover. But how much should you spend on bathroom renovations?

Let’s break down the details.

Factors to Consider When Remodelling Your Bathroom

A typical bathroom remodels project in Australia can cost from $10,000 – $40,000. Depending on factors such as the size of your bathroom, materials used, labours, fittings. It also depends if you plan on going DIY or hire a professional to do the job for you.

  1. Design
  2. Permits
  3. Walls
  4. Floors
  5. Plumbing
  6. Lighting
  7. Cabinets
  8. Mirrors
  9. Toilets
  10. Shower or Tub or both?

#1 Design – Average Cost: $1,000-$4,000

How do you want to feel when you’re inside? Relaxed? Uplifted? Calm? Joyful? Hiring an expert bathroom designer can come with plenty of benefits. You can also opt to go partly DIY for freedom in the choice of fixtures and cost.

#2 Permits  Average Cost: $385 – $1,893

We mentioned partly DIY earlier because you can’t work on a bathroom renovation entirely by yourself. Australia set regulations on who has permission to work on these kinds of projects, and they vary by state. For example, in all states, only licensed contractors can work on plumbing and electrical work. There are authorised contractors with full permits to operate and supervise bathroom renovations.

#3 Walls Average Cost: $7 to $25 per square foot

Compared to other parts in your home, bathroom walls are always exposed to moisture, from sink splashes to hot shower air. Consider the material used because each one has its pros and cons. For example, tiles are 100% waterproof and cost-effective but can give a slightly “hospital” appearance. While going full-on bathroom paint prevents molds and mildew, but can be quite costly. 

#4 Floors Average Cost: $600 to $1000

When choosing bathroom flooring, you need to consider moisture levels again, but, at the same time, won’t sacrifice style. Materials can range from marble, tiles, porcelain, paint, vinyl, etc. Consider visiting a showroom so you can get a first-hand look and feel.

#5 Plumbing Average Cost: $13,600 (40 sq.ft. first floor bathroom – standard fixtures)

One of the most common problem areas in the bathroom is plumbing. You’d be surprised how much hair, dirt, and gunk goes down your drain. Take note that the larger your drain, the less likely it is to get clogged. Typical residential plumbing uses one and ½ inch pipes, but we recommend upgrading to a 2-inch unless your space won’t allow it. 

#6 Lighting Average Cost: $30 to $40 for a single sconce to $400 to $500 or more for a multi-light

Do you want fixed lighting, or do you want lights that change according to your mood? Function-wise, you want your lights to be bright so you can properly apply makeup or shave. Aesthetic-wise, you want it to be warmer, dim. You can consider getting a dimmer switch so you can adjust in-between.

#7 Vanity & Cabinets Average Cost: $300 to $3,800

Bathroom vanity and sink types include wall-mounted, pedestal, vessel, framed, under-mount, and drop-in sinks. Also, consider how much storage you need when canvassing for cabinets.

#8 Mirrors Average Cost: $20 and $100

We can’t imagine a bathroom without any mirror. Most likely, it’s your face you’d like to see first thing in the morning. You can’t just put a regular mirror in there too because it won’t hold up to humidity. We recommend considering a moisture-resistant framed bathroom mirror. As a rule, the mirror should measure several inches less than the vanity or sink area. For example, if you’ve chosen a 42″ single sink vanity, you will want to select a mirror that’s the width (frame included) doesn’t exceed 42 inches. And framing. 

#9 Toilets Average Price $300 – $400 

Features to consider when choosing your toilet include height, bowl shape, colour, style, and flushing technology. Bathroom showrooms, DIY sheds, and online stores offer a vast range of designs to suit all room sizes and styles.

#10 Shower, Tub, or Both? Average Price $700-$1,600

This choice heavily relies on your preference, space, and budget. Having a shower-only is an excellent option if you’re renovating a small bathroom. If you’ve got kids (or planning to have one), getting a tub can make bathing them a breeze.


There’s no exact amount on this question. It depends on your renovation budget and how much you’re willing to spend. Take a good look at your priorities and budget. Do you need a full renovation or just fix a few things here and there? How often do you want to remodel your bathroom? Is it just for aesthetics or necessity? Take your time to research or invest in getting an expert to help you find a solution for your needs.  But we hope this gives you a bird’s eye view on how much you should spend on a bathroom renovation.
