Showers create warm, humid conditions that are tough on bathrooms. When this moist air hits cooler surfaces like walls, ceilings, mirrors, and grout, it condenses into water. If the moisture doesn’t dry properly, it can lead to mould and mildew growth, which damages surfaces and creates musty odours.

Over time, constant exposure to steam can weaken paint, causing it to peel, bubble, or discolour. It can also break down grout and sealants more quickly. In poorly ventilated bathrooms, trapped moisture can even contribute to wood damage in cabinetry or framing
