When renovating a bathroom, cost is a considerable factor for deciding on style, features and amenities. But how much should you expect to budget for when planning a bathroom refresh?
For an estimate figure, you can expect to spend anywhere between $10,000 to $35,000+. The cost can vary depending on the size of your bathroom, the materials used, as well as any labour costs. However, it is possible for a renovation to cost lower around $5000 if you are willing to swap out a few items or keep the refresh a largely cosmetic update.
Expect to pay more if you are thinking of a complete renovation or:

Wondering who you may need to hire for your bathroom project? These are the most common trades you will need to call on:
Bathroom builders can manage and run your project completely on your behalf, and often have all trades on staff to cover different aspects of the job. If not, they can coordinate sub-contractors. This will cost you extra but will take the hassle out of any renovation job.
If you are hiring individual trades:
Architects help to design floor plans for your new bathroom, ensuring everything is logically laid out to suit your lifestyle. Expect to pay for the privilege of their expertise.
Electricians can help install lighting, power points, heating, ventilation and much more.
Painters will need to paint any areas that are not covered by tiles or other elements, preferably with a moisture and wear-resistant paint.
Plumbers are perhaps the most crucial tradie on your project, so make sure you hire one who has a good track record of working on bathrooms.
Tilers are another crucial trade who can can make or break the look of your bathroom. They also need to get small details right, like making sure your shower recess drains properly.
Waterproofers will use a variety of sealants and membranes to make sure your bathroom is properly sealed - so you don't have leaks sprouting up all over the place.
Always use tradies who are licensed for your bathroom reno.
Most elements of a bathroom renovation, such as plumbing and tiling require the use of a licensed contractor. A complete bathroom renovation will typically require a licensed builder, with some states having a licence specifically for bathroom and kitchen renovations. Individual trades such as plumbers, waterproofers and sparkies all need to be qualified and licensed.
When it comes time to hiring a contractor make sure they are right for your job. Some questions to ask then include:

Some of the major costs to plan for include:
Plumbers charge a call-out fee of $60 to $100, with hourly rates anywhere from $100 - $150 depending on the plumber. The fee your plumber charges will depend on where you live and may vary according to the plumber’s skill level.

The size of your bathroom is going to be a major factor in the cost of your renovation, and since so much of a bathroom is tiled, you need to know what the boundaries of your budget are. Expect to be quoted on a per square metre rate by bathroom tilers, which could range from $35 per square metre to $120 per square metre. $60 per square metre is the average for laying bathroom tiles. The cost of the actual tiles would be on top of this, so be sure to factor this in.
For wall tiles expect to pay from $20 to $28 per square meter for standard white ceramic wall tiles (600mm x 300mm) to $68 per square metre for steel grey polished porcelain wall tiles (150mm x 600mm). Moving up in price expect to pay around $86 per square metre for handmade Spanish white gloss ceramic subway tiles (150mm x 75mm) and $159 per square metre for artisan manufactured ceramic wall tiles (200mm x 200mm).
For floor tiles expect to pay $35 to $50 per square meter for ceramic or porcelain tiles, $50 to $100 per square meter for high quality porcelain and $80 to $130 per square meter for high quality natural stone tiles.
