Bathroom waterproofing cost

On average, expect to pay around $500 to $800 for the cost of bathroom waterproofing.
You can get a lower price if you are waterproofing more than one bathroom or if the waterproofing is part of a more extensive renovation or construction project.

Bathroom waterproofing costs will go up if the bathroom that requires waterproofing is on the second storey or if it is a wet room. This is because the contractor also needs to waterproof the bathroom floor.

How Much to Pay a Bathroom Waterproofer?

Expect to pay $50 to $150 per hour for the cost of bathroom waterproofer. However, for some contractors, they cost as little as $40 per square metre. Bathroom renovators charge around $65 per hour. This is your best option if you’re going for a complete bathroom renovation and not just waterproofing.

However, if you have the option to hire waterproofing experts then that is still your best option. Waterproofing specialists charge around $32 per hour. This is the national average hourly charge of waterproofers.

How Much to Pay When Waterproofing a Shower?

Waterproofing a shower usually costs less compared to bathroom waterproofing. Showers occupy a smaller area and will require fewer waterproofing supplies.

Just like with bathroom waterproofing, you can hire a tiler, bathroom renovation specialist, builder, or waterproofing experts to waterproof your shower.

The hourly rates are also the same as those for bathroom waterproofing. $65 for bathroom renovations specialists, $32 for waterproofing specialists, and around $50 to $150 for tilers.

If you have a glass shower enclosure, then you might want to ensure that the tradesman that you hire is also capable of working with glass.

What Factors Affect the Cost of Bathroom Waterproofing Job?

Size of the Project

Size is a factor when trying to determine how much does waterproofing cost. A larger bathroom will require more materials to be waterproof.

Large bathrooms will also take more time to finish, and this will significantly affect waterproofing costs, especially if you are paying your tradesman an hourly rate.


Your location will also play a role in determining how much you have to pay for your bathroom waterproofing. Labour rates are different depending on where you live.

Aside from your location, the location of your bathroom also matters. As mentioned earlier, bathrooms located on the second storey or higher requires total waterproofing.

If you only have a bathroom on the ground floor of your home, expect a slightly lower bathroom waterproofing cost. Restrooms located on the ground floor only require waterproofing for the walls.


Emergency services are always more expensive, and this includes waterproofing services. As much as we want to avoid emergencies, there are instances when such instances arise.

If the only available time that you have is during the weekend, try and choose a contractor who works typically during weekends. This can save you money because they will be working during their standard days of operations.

The extra cost of emergency services underscores the need to hire licensed tradespeople. Some contractors might offer their services for a lower fee, but their output might be of questionable quality.


Aside from the number of materials, another factor that affects home waterproofing cost is the kind of materials that your contractor will use.

The quality of the waterproofing membrane that your contractor will use will affect the cost of a waterproofing project.

For your bathroom or shower to be waterproof, a continuous layer of waterproofing membrane needs to coat your bathroom or shower. This will prevent water from passing through it.

A suitable waterproofing membrane needs to be durable and tear-resistant. It should be flexible and elastic so it can cover cracks. A flexible membrane will ensure that all areas of your bathroom are waterproof, even those that are not entirely flat.

If you have a bathroom with a skylight, be sure to use a waterproofing membrane that is UV stable. This will ensure that your waterproofing membrane will last long even after prolonged exposure to sunlight.

Great waterproofing membranes have excellent water-resisting properties. You can look up waterproofing membranes online and see how they performed during water testing.

Using sub-par waterproofing membranes can result in low-quality results, and you might have to repeat the waterproofing process.

The cost to reseal showers and bathrooms is an expense that you can easily avoid with the help of high-quality waterproofing membranes.

Frequently used waterproofing membranes include:

  • Acrylic
  • Chlorinated rubber or latex
  • Epoxy
  • Polyurethane
  • Polyester resin
  • Tar epoxy

State of the Bathroom

If your bathroom is in great shape, then waterproofing it will go smoothly. It also means that you don’t have to worry about extra steps that will add to your waterproofing expenses.

It’s a different story when waterproofing shower walls and floor that’s damaged. When you have damaged or cracked bathroom tiles, the damaged ones need replacement before the contractor can proceed with the waterproofing process.

What is Bathroom Waterproofing?

Waterproofing is a standard that you need to comply with as per the Building Code of Australia. Be sure that your waterproofing specialist can help you comply with strict waterproof standards.

Waterproofing is the process of making your bathroom or shower waterproof or water-resistant. It is suitable for wet areas such as bathrooms, showers, swimming pools, and even roofs.

When you have a waterproof bathroom, it will not get affected by constant exposure to water. You can accomplish these several ways, such as using waterproof tiles or shower sealing systems.

You can waterproof a shower recess by using total waterproofing supplies. Your waterproofing specialist can waterproof your bathtub through bathtub refinishing, the process used to reseal a bathtub surface.

Waterproofing offers water ingress protection. This means that wet area waterproofing will prevent water from getting into the structure below the waterproofing membrane.

Why is it Important?

Aside from complying with the law, waterproofing is a surefire way of protecting your investment.

A house that is not waterproof can spring leaks that can result in water damages. Water damage is especially damaging if it occurs on the second storey of a home because it exposes the area below it.

Waterproofing can save you from unnecessary expenses such as the need to purchase sump pumps to prevent your basement from flooding.

Water damage can also weaken the foundation of your home. A weakened foundation will put your family in danger and can shorten the life of your home.

Investing in high-quality waterproofing services can help you avoid all the headaches and heartaches that a water-damaged house brings.
