A bath on its own – used only as a bath does not need to be waterproofed. However, if you are planning on having an overhead shower above the bath then we would recommend that you consider how best to waterproof the installation.
Classi Seal is our original product, favoured by installers since 2006 for waterproofing the ledge between the bath and the wall. It’s a reliable choice to ensure the critical junction between the wall surface and the bath is watertight.
Classi Plus should be used when you are fitting smaller format tiles like mosaic or subway tiles, or if you plan to use a liquid membrane in conjunction with your Classi Plus. Classi Plus also features a taller upstand which could be useful in some installations. For those wanting to waterproof the entire wall for extra protection when using the overhead shower, a Classi Waterproofing Kit for Shower Trays and Baths contains all the necessary materials.
