Bathroom Waterproofing

What is included

We waterproof the entire bathroom floor and wet zones as one continuous system — shower, bath junction, vanity, toilet and the full floor plane — so there are no untaped edges where water can find a path. Ideal for tile-to-tile renovations, apartment updates and knock-down rebuilds.

Our applicators are accredited and every installation is documented with dated photographs, product batch numbers and a signed certificate for your file, your tiler and your insurer.

Our scope of work

  • Complete floor and wet-zone membrane system
  • Movement joints, junctions and penetrations sealed
  • Drain and waste body sealing
  • Flood testing with photographic evidence
  • Written certificate of compliance for tiler and owner
  • Coordination with your tiler, plumber or builder

When you need it

  • Whole-bathroom renovations
  • Apartment updates and kitchen-bathroom packages
  • New-build first-fix waterproofing
  • Insurance rectification works

Frequently asked questions

Straight answers to the questions we are asked most often across Sydney.

How much does bathroom waterproofing cost?

from $1,250 is our starting price for a standard bathroom waterproofing job in metropolitan Sydney. Final pricing depends on the size of the area, the condition of the substrate, access and whether any tile or substrate repair is required. We confirm a fixed, itemised price before work begins — never an hourly estimate that grows.

How long does bathroom waterproofing take?

Expect 2–4 days. Most jobs of this type are completed in a single visit by a licensed tradesman, with the area protected, cleaned and left ready for use. Larger works such as balcony rectification may take several days depending on access and the extent of tile removal.

Is bathroom waterproofing covered by a warranty?

Yes. This service carries a written 15 years warranty, issued with a photographic record of the installation. The certificate covers both labour and materials for the waterproofing work we performed. If anything we installed fails inside the warranty period we return and rectify it at no charge.

Do you need access to the property first?

Not to give you a price. Send photos of the affected area through our quote form and we will come back with a fixed price, usually within the hour. We only attend the property for a formal inspection when the photographs are inconclusive or when a certificate is required by your body corp, insurer or tiler.
