Mould and fungus in shower

Hi

Every few weeks the mould appears on the ceiling and fungus grows in the shower. See attached pic

Is it a serious problem?

Is that the corner of the shower or another part of the bathroom? I'm going to assume it's the shower itself

Looks like water is pooling in the corner, there is no silicon to seal the joints but there is evidence of it existing at one point.

Also, the amount of installers that can do a custom wet room style shower properly in Ireland can probably be counted on one hand, so it's fair to say there is probably a huge amount of water damage behind those tiles, the fungus sprouting just confirms it.

Thanks. That's the corner of the shower although it happened in another area where the shower tiles end too and comes on the ceiling. It's an extension and is freezing in the winter. Maybe knocking it and redoing is the only option ?

lack of / insufficient ventilation can cause mould. Possible solution to consider re mould is to fit an extraction fan and a wall mounted heater. I assume that the heat generated in the shower area - by the hot water gets ‘trapped ‘ in the shower area

Based on a single picture of the corner of a badly done shower, sure knock it down. Or get a consult from a decent builder. Regardless, that's at the point where I would starting with pulling that section apart to see how much damage there is behind it.

Fyi, showers require maintenance. Repairing cracks in the grout, removing and replacing silicone when it fails. They are one of those things where the longer you leave something the more costly the repair bills gets.

If you have a fungus fruit like that then you have a food source for the fungus, usually a cellulose source such as wood, and its actively rotting in a very wet environment. It's localised wet rot effectively. Time to have that whole shower removed and re-done.
