Difference Between Surface Sealing and Conventional Bathroom / Shower Waterproofing

Oct 15, 2025

When it comes to fixing a leaking shower or bathroom, homeowners often face two choices surface sealing or conventional waterproofing. While both aim to stop leaks, the difference lies in how thorough and long-lasting each method is.

At Everseal, our team of bathroom waterproofing experts believes in doing the job once and doing it right, saving you time, stress, and money in the long run.

What Is Surface Sealing?

Surface sealing is a quick, short-term solution. It involves applying a sealing product over the top of your existing tiles to stop leaks temporarily. No tiles are removed in this process; it simply covers up the issue instead of addressing the root cause.

The downside? You can’t see what’s happening underneath the tiles. If there’s existing damage, rot, or even white ants lurking below the surface, the sealing traps these problems within the cavity. Over time, this can lead to further damage, potentially making the issue far worse.

So while surface sealing might seem like a cheaper fix, it’s only masking a deeper problem  and that problem doesn’t go away.

Why Conventional Waterproofing Is a Better Long-Term Solution

Here, our approach to shower waterproofing and bathroom waterproofing is different. We don’t just seal over the problem  we fix it properly.

Our process involves carefully removing the tiles, inspecting the area underneath, identifying the source of the leak, and repairing or replacing the waterproof membrane. Once that’s done, we re-tile and reseal the area to ensure long-term protection.

This thorough method prevents further issues such as timber rot, structural damage, or subfloor deterioration caused by a faulty membrane. If water has already damaged the subfloor, your structure may become weak and unsafe to walk on. It’s simply not worth the risk. A proper fix now will save you from expensive repairs later.

The Risk of Ignoring the Underlying Problem

When leaks go untreated or are only surface sealed, moisture continues to spread beneath the surface. This can cause serious structural issues over time, including:

  • Staining on carpets or walls
  • Damp door jambs or musty smells
  • Discoloured grout joints
  • Cracked or lifted floor tiles
  • Creaking floorboards
  • Staining on ceilings (in two-storey homes)
  • Increased ant activity due to dampness

If you’ve noticed any of these signs, it’s time to act fast. Ignoring them can result in higher costs and major damage to your property.

Affordable and Targeted Waterproofing Solutions

Many homeowners believe that fixing a leaking shower or bathroom means a complete renovation  but that’s not true. At Everseal, we can perform targeted resealing shower repairs without the need for a full remodel.

We can remove just one or two rows of tiles around the perimeter and the full floor, then apply new waterproofing and re-tile. We’ll even help you choose a replacement tile that matches your existing bathroom design.

For example, a standard shower (around 900 x 900mm) typically costs around $1,900 + GST to remove, re-waterproof, and re-tile the base  and takes about five days to complete. While surface sealing might cost about half that amount, it won’t last as long. Over time, the hidden damage can cost significantly more to fix.

So, if you want a lasting solution that truly protects your home, shower resealing done the right way is the smarter investment.
