The cost of replacing a whole bathroom will depend on the costs of the following:

• tile demolishing, 
• making good walls,
• waterproofing,
• tiling, plumbing,
• electricity, and
• materials or fittings.

In Australia, a basic, small bathroom renovation can cost $20,750 to $27,000. Larger bathrooms with higher quality products will cost $25,000 to $30,000.

A bathroom renovation is one of the greatest investments you’ll ever make for your home. Whether you’re looking to sell the house or just improving or upgrading the look, bathroom remodeling will be very beneficial in the long run. However, total renovation can cost you a lot as it will involve replacing old tiles and installing new ones, upgrading the plumbing, materials, and fittings, and fix electricals if needed. Depending on the size of your bathroom, renovation may cost from $20,000 to $40,000. You might think, how can you cut down the costs but still have great results?

Materials and fittings are usually the biggest chunk in the total cost of bathroom renovations. When planning for the renovation, it’s best not to overdo changes or installation when it comes to materials and fittings. Go for the simpler products especially if you are tight on budget. It’s even better if you let interior designers take a look at your bathroom to give more insights and ideas on how to cut costs.
