Bathroom Waterproofing

Over 25 years ago we started as a waterproofing business focusing solely on wet areas and have since evolved into full bathroom renovations, laundries and shower repairs. With so much time spent and experience gained from repairing water damaged areas, we love the chance to be involved in the initial planning process. The combined knowledge we have of waterproofing processes and what’s required later down the track to the completion of the job, allows us to guide clients in the right directions from the start, which in turn can save our clients time and money. We are fully licensed and follow all current standards of the Building code of Australia V2 3.8.1 and the Australian Standards AS3740, including 7 year warranty.

Bathroom waterproofing services ensure that your bathroom is protected against water damage. Professional technicians install waterproof membranes and barriers to prevent leaks and protect flooring, walls and ceilings.

I am very happy and definitely made the right choice.

      Thanks guys, great job.

    • I was initially confused about what design would best suit my house. After a friendly and detailed discussion with Custom Bathrooms I was able to make an educated decision on what I wanted and what was the best choice. My bathroom looks fantastic and I am glad I chose you and would certainly recommend them to anyone.

      Joe & Nancy -

    • We had just purchased a house and it needed a little work to be done in our bathrooms. As we had just spent all our money, money was not something we had a lot of. With the help of Custom Bathrooms we renovated both bathrooms on a budget and are really happy with the outcome. I don’t have any hesitations in recommending Custom Bathrooms to anyone.
