Hot Mop Shower Pan: The Gold Standard 

The hot mop shower pan has long been considered the gold standard in waterproofing shower areas. Its meticulous installation process involves applying layers of hot asphalt or tar-soaked felt paper to create a seamless and waterproof membrane. This method offers excellent durability and reliability, making it a preferred choice for many homeowners and professionals.

Other Waterproofing Methods: Pros and Cons 

  • Tile Shower Membrane: Tile shower membranes, such as waterproofing membranes or liquid waterproofing solutions, offer a flexible and easy-to-install option for waterproofing shower areas. However, they may require additional maintenance over time to ensure continued effectiveness, and improper installation can lead to water damage issues.
  • Sheet Membrane: Sheet membranes, typically made of PVC or similar materials, provide a quick and straightforward waterproofing solution. They offer good durability and are resistant to mould and mildew. However, they may not offer the same level of customisation as hot mop shower pans and can be prone to tears or punctures if not installed correctly.
  • Cementitious Waterproofing: Cementitious waterproofing involves applying a cement-based coating to the shower area to create a waterproof barrier. While cost-effective and relatively easy to apply, cementitious waterproofing may not provide the same level of long-term durability as hot mop shower pans and can be susceptible to cracking over time.


In conclusion, choosing the right waterproofing method for your shower area requires careful consideration of various factors, including durability, ease of installation, and long-term maintenance. While hot mop shower pans remain a top choice for their reliability and effectiveness, other methods may offer suitable alternatives depending on your specific needs and preferences. By weighing the pros and cons of each option, you can make an informed decision to ensure a waterproof and durable shower space for years to come.
