Q: My shower screen is leaking?

A: Whilst showers are a barrier they are not water tight and some leakage from the shower will be evident due to overspray that could "bounce" under the door. This is normally nominal

The purpose of the 12 months installation warranty for showers is to verify the cause if leaks occur and provided are the most common aspects.

If a shower leaks through the silicone, noting that we install showers and seal on the outside perimeter only, this can take the smallest pin prick/ bubble and a leak will occur.
We seal ONLY TO THE OUTSIDE PERIMETER.
Why – The outside is the barrier of seal for the shower. Leaving water between components (Wall channel and wall, Shower sill and floor) a way of egressing back to the inside of the shower.

The largest complaint is a shower leaking behind the shower and causing damage and this is something longer term.

We face fix our showers to the tiles with a preventative measure, we apply added silicone to the back of the U channel and squeeze between the wall and floor junction.

With movement of the house or settlement the floor and wall can open up, hence we are applying this preventative measure to seal.
However, it is recommended that caulking compound is applied prior to the shower installation as the caulking compound does have more flexibility of compound and this is done by the client’s caulker and not within our scope of works.

With this opening up between the floor and wall water seeps through and if the waterproofing has done its job damage will not appear, but if the waterproofing behind the tiles has failed it will cause damage. This is not a warrantable item from our perspective and the claim needs to be directed to the tiler/waterproofed for rectification. A thermal camera is recommended to verify without removal of showers and tiles to verify.
