Every Shower Needs To Be Waterproofed

Within the Classi range we have three options, depending on budget and wall finishing.

If you are finishing with wall panels, we would recommend using Classi Seal.

If you are tiling you have two options:

If you just want to make sure the ledge between the tray and wall is waterproofed then you need Classi Plus.

To waterproof the entire enclosure and walls then you should use the
Classi Waterproofing Kit.

When Do I Need To Waterproof A Bath?

We would recommend protection for baths with overhead showers.

If you are finishing with wall panels, we would recommend using Classi Seal.

If you are tiling you have two options:

For waterproofing between the ledge of the bath and the wall you need Classi Plus.

If you want to waterproof the whole area creating a barrier behind the tiles, you need a
Classi Waterproofing Kit.

Advantages To Using A Waterproofing Kit:

Our Classi Waterproofing Kits are a complete set of everything you need to fully waterproof the showering area.

They contain everything from pipe covers to silicone and tiling can begin immediately after the kit is fitted, saving valuable drying times.

Classi Wetroom Kits are compatible with specially designed wetroom wastes which allow the membrane to interlay ensuring that escaped water is diverted into the waste.

Classi Bath or Shower Kit Includes Classi Plus for complete waterproofing from the shower/bath ledge to the top of the membrane.
