The most common signs of a leaking shower are:

• wet carpet/ buckled floorboards at the bathroom door or in the room behind the shower
• stains on the ceiling below the shower/ bathroom
• swollen architraves/ door frame or skirting boards near the bathroom
• bubbling/ blistered paint on the wall/s behind the shower
• rotten or swollen base of the vanity cabinet (if not on legs)
• loose or lifting floor tiles (can be a sign that the flooring below is damaged from water)
