How much tanking do I need?

The complete floor area of the wet room MUST be tanked. The bottom of the walls must be tanked all the way around the room turning up from the floor by a minimum of 100mm. All walls in the showering area (wet zone) and splash zone (splash zone is 600mm past the wet zone) MUST be tanked from floor to ceiling.

Internal and external corners (optional)

If the floor area of the wet room is rectangular, measure the width in metres x the length in metres. This illustration will give you the total area: 2.5m x 1.2m = 3m²

To calculate the floor area if the floor area is an irregular shape, or if there is a curve in the room, section it off to make rectangles or squares and then add them together.

How much tape do I need?

You will need enough tape to cover all the joins ie. around the perimeter of the room where the wall joins the floor and any vertical wall to wall joints in the wet zone and splash zone areas.

How to calculate the surface area

If the floor area of the wet room is rectangular, measure the width in metres x the length in metres. This illustration will give you the total area: 2.5m x 1.2m = 3m²
