Choosing tiles is a main consideration in your bathrooms. It’s the main material that will be used and impacts functionality as well as aesthetics. Not all tiles are the same, so it’s important to know the buying criteria so you can choose the right tile for the right application. 

In this episode of the podcast, Frances is joined by Tiling expert, Richard Earp from Earp Bros.  Richard shares his amazing knowledge on tiles to discuss the different types of tiles and differences between poor and good quality tiles.  



Different Types of Tiles 

  • Ceramic- the material has a moisture absorption of more than 3%, ideal for walls 
  • Gres Tiles- the material has a moisture absorption of between 3% and 0.5% 
  • Porcelain- are low absorption product (0.5% or less).  Can be used on the inside, outside, wall and floor  
    • Technical Porcelain- has a 0.1% moisture absorption and are generally used in high-performance areas such as airports, shopping centers, and Melbourne Exhibition Centre. 
    • Other types of porcelain: 
      • Glaze Porcelain 
      • Full Body Porcelain 
      • Double Charge Porcelain 
      • Triple Charge Porcelain 
      • Polished Porcelain 
    • Things to consider when choosing porcelain material: 
      • Porcelain varies in quality mainly with accuracy and surface flatness which effect how its laid and the overall finish 
      • Design and the surface 
      • Colour separation rooms for glazes to create a depth of colour not seen cheaper version tilesThe more colour separations used, the better the quality. 
    • Cheaper Porcelain tiles generally cut corners in the manufacturing processReduced processing of raw materials, the use of more glass as a fluxing agent to incorporate with ball clays and porcelain claysOn the other hand, high-quality tiles have lesser fluxing agents, longer firing times using higher technology to press, and the raw materials are extracted.  
  • Terracotta-can be formed in different ways-extruded, molded and etc. It has a very high absorption material and generally requires sealing.  
  • Cement tiles- like terracotta, cement tiles also require sealing 

Placing a tile that has a higher (10%) moisture absorption on the floor is not ideal as they are not dense. If you drop something on the floor, it can easily crack, break, or chip. The moist absorption gives an indication of what type of materials the factories are manufacturing 


There are sealers that are designed to breathe in stone, terracottas and cement.  

  • Topical Sealer- sit on top of the material 
  • Penetrating Sealer- shields against moisture penetration and chemicals. Usually, they provide invisible protection without changing the surface appearance, and most products are breathable, allowing moisture vapor to escape. 

Tile Sizes 

How the size of tile impacts your selection 

  • Spatial Awareness - larger format tiles can look great in some spaces, but a small space with large format tiles in many instances won’t work. Instead of a 800x800mm tile, 600x60mm may be better. Cost – will cost more to use larger format tiles – product and laboutPorcelain sheets (2.7, 3.2 meters sheets, 1.2 meters wide.)- needs a specialist to install which costs more than 20-30% of premium. Why it costs more? 
    • Delivery of the material  
    • Kitchen benchtop- must be fabricated off site and it get done by machine in specialist factories 
    • Intricacies of installing them 

Tile Types 

  • Rectified- the tile is perfectly straight 

When buying tiles manufacturers should be able to provide you with the following: 

  • Installation Procedures 
  • Sealing guide 
  • Cleaning guide 


Earp Bros joined the green building council in 2004 and was the first company that went through product certification. They use two certification systems: 

  • Global Green Tags  
  • Product Declare 

Sustainable Criteria 

  • Green Tag Accreditation 
  • Life cycle assessment of materials  

Tips when deciding on your tiles and getting a good result at the end 

  • Understand what you need- I.e High-maintenance vs low maintenance materials 
  • Visualise what you want before you start your journey- Create a pinterest board 
  • Be fully accurate on what your budget is 
  • Surround yourself with professionals. Find trustworthy companies and people 

Tile trends 

  • Large format tiles 
  • Natural materials- Zellige tiles are popular now       
  • Patterns and sheets of design, like big florals
