Waterproofing and tiling

This can cost between $750 and $1,000 for an average sized bathroom.

Before you get started on tiling, your bathroom will need to be waterproofed. In most cases, your tiler will include waterproofing costs within their quote.

Tilers generally charge on a per square metre basis, and you can expect to pay from $30 to up to $120 per square metre.

You will also need to consider additional costs such as the removal of existing tiles, laying asymmetrical or contrasting tiles which require a high level of detail, as well as leveling, grouting and sealing or polishing tiles.

Finished waterproofing, ready to begin tiling


You will need to hire plumbers for moving or installing fittings such as bathtubs, showers and toilets.

Plumbers normally charge an hourly rate which can be somewhere between $70 to $90. This cost will vary depending on the complexity of the work, the size of the project and accessibility of the space.

Other tradespeople
Depending on the extent and the needs of your renovation project, you might also need to enlist the help of other trades people, such as:

  • Carpenters: $50-$60 per hour (for custom-made cabinets or shelving)
  • Builders: $60-$70 per hour (for laying plasterboard, moving walls, installing frame for the bathtub)
  • Electricians: $70-$80 per hour (for new lighting, underfloor heating, new power points, extraction fans, heated towel rails and hot water cylinders)
  • Painters: $35-$45 per hour (for painting walls, doors, and ceiling)

The location of your property will impact the final renovation cost. The cost of hiring tradespeople in big cities is higher than in smaller towns, so you will need to consider this as you work out your budget.

Low cost bathroom renovations

If you are looking to keep your bathroom renovation costs as low as possible, you should consider working with the existing plumbing outlets and electrical points. This can save you thousands of dollars as moving showers, toilets and other fittings will hugely increase your labour costs.

If you’re a handy person, you can do some simple DYI updates which can make a world of difference in your bathroom.

These can include small changes such as replacing handles and door knobs, and installing new mirrors, towel racks, and tapware. You can even paint the bathroom yourself. You will be surprised to see what a fresh coat of white paint can do to a room.

Remember that you are not legally permitted to do tiling or install electrical connections yourself, so you will need to enlist the help of professionals.
