Custom Made Shower Tray Formers

With our made-to-measure service you can order the precise shape and size of shower tray former you need. Simply send us your drawing showing overall dimension, waste centre position (min.300mm from edge) and any flat areas or out of square angles required.

We offer a full and free advice service in relation to planning your wetroom tray,so please contact us on 01387 270252 at an early stage for further guidance on the ideal specification for your project.

To Purchase

  • Choose the size of tray former you require (dimensions are given and a diagram will appear to show waste positioning on selected former).

  • Select between vinyl or tiled floors and the relevant grating options will appear below.

  • Finally select either a horizontal or vertical waste outlet.

    Note: For made-to-measure formers, please input the dimensions required in mm (taking care not to exceed the maximum sq.m size selected). Choose either the centred or off-centre waste option. For the off-centre waste you will need to send us, by fax, email or post, a brief sketch clearly showing the exact centre point of waste required (no closer than 300mm to any edge). You can then continue by selecting tileset and waste options, as with the standard formers. If you have any questions please contact us prior to ordering.
