Shower Tray and Baths with Overhead Showers

Classi Seal is our original product, favoured by installers since 2006 for waterproofing the ledge between the shower tray or bath and the wall. It's a reliable choice to ensure the critical junction between the wall surface and the bath or shower tray is watertight.

Classi Plus is an upgraded version of Classi Seal, gaining popularity for its enhanced features. It has a taller upstand compared to Classi Seal, and it's equipped with a fleeced outer layer compatible with tile adhesive and liquid sealing membranes.
