All aspects of wetroom design are covered in our new guide


Here’s an overview of the topics our wetroom design guide covers:

What is a Wetroom?

A wetroom is a shower area where there is no conventional shower tray sitting on the floor. The tray-less sector is normally broken down into two main categories “Level access showers” and “wetrooms”. We look at the common principles of tray-less showering…

  • Wetroom Principles
  • Coventional Shower Trays
  • Advantages to Trayless Showering

Types of Shower Area:

In the bathroom industry, people often refer to either a “wetroom” or a “level access shower area”. There is a lot of overlap between these two terms, but generally the term wetroom is used for tiled finishes and level access showers refer to a vinyl floor finish, so this is the definition we will work with in this guide…

  • Tiled Wetrooms
  • Slope to Falls – What should you choose?
  • Infinity Wetrooms
  • Rack Mounted Systems
  • Level Access Shower Areas
  • Communal Shower Areas

Wetroom Design – Planning Your Shower Area:

Planning the shower area is about making the best use of the space available to create an attractive and practical showering area to meet the needs of the client. Before getting too far ahead in the wetroom design, think about where the water will be draining to. If it is a refurbishment project, where is the nearest downpipe? If your waste is positioned reasonably close to a drainage point, then this will make installation a lot easier…

  • Routing Complexity
  • Waste Outlet Position
  • Accessibility
    – Hoist Systems
    – Shower Seating
    – Accesible Wetrooms with shower screens
  • Multiple Cubicles
  • Preformed Joints

Wet Floor Build-ups for perfect wetroom design:

Aquatecnic Hardwood-Ply Shower Tray Formers come in a range of standard sizes and can also be “made to measure” to suite even the most unusual shower room. These mainly fall into three varieties: square gratings (traditional) with a 4-way fall, linear gratings with a 2-way fall or wall grating with a one-way fall. In all cases the fall is cut into the wooden surface and is calculated to give the optimum performance. The shower trays have a hole cut to fit the appropriate waste and come with a waste support to provide extra strength at the thinnest point of the tray…

  • Pre-formed Shower Tray Formers
  • Mortar Slope to Falls or Shower Tray Former
  • Wooden Floor Build-ups
  • Made to Measure Options
  • Waste Gullies
  • Traditional Gratings
  • Linear Gratings
  • Underfloor Heating
  • Insulation

Waterproofing design for wetroom Shower Areas:

There are several types of waterproofing that have been used for wetrooms including liquid based systems, sheet systems and glass fibre lay-ups. We believe that the simplest and most secure is a good quality, independently approved liquid-based system…

  • Why Tank?
  • Tanking Area
  • Products Required
    – Aquaproof Primer
    – Aquaproof Tape
    – Aquaproof Pre-formed Corners
    – Aquaproof Pipe Sleeves
