The infinity former is easy to position and comes with full installation instructions. If you have any queries just contact us and one of our technical experts will be happy to talk you through the installation process.

Left and Right Hand Options

The hidden waste outlet can be positioned on either the right or left of the shower. When purchasing just choose either the left or right hand option.

Stock Sizes

The infinity former comes in 4 stock sizes with a choice of left or right hand hidden wastes. All stock sizes are available to buy online just make your selection below.


If our stock sizes aren’t suitable for your project we can manufacture bespoke options of both the former and the hidden drain which will perfectly meet your requirements. Bespoke formers can be manufactured from 600mm in length up to 2000mm and can also be manufactured in thicker birch plywood (up to 30mm) should the length of the slope to fall require it.

To Purchase

  • Choose your formers size
  • Pick your grating
  • Choose vertical or horizontal waste outlet

Note: For made-to-measure formers please provide us with dimensions A,C & E as shown in diagram next to size option.

Please be aware the "c" measurement is the total width of the former including a 50mm trimmable shoulder on each side. Therefore width of the sloped section of the former is 100mm less than the total width.
