A toilet leak from the base often occurs due to a damaged wax ring – the seal between the toilet base and the drainage pipe. The wax ring creates a tight seal that prevents water and waste from leaking out of the toilet and into the bathroom floor or subfloor. Over time, the wax ring can become compressed, cracked, or dislodged, allowing water to leak out from the toilet’s base. Another possible cause of a leak from the toilet base is a loose or damaged mounting bolt, which secures the toilet to the floor. If the bolt is loose or damaged, the toilet may shift or wobble, causing the wax ring to become misaligned and allowing water to leak.
