Maintaining a tile shower is key to long-term waterproofing. Regularly clean the tiles and grout to prevent soap scum and hard water buildup, which can damage the grout sealer. It is crucial to inspect all silicone caulk at the corners and where the wall meets the floor, as these joints are the most common points of failure. If the caulk shrinks or cracks, it must be removed and replaced immediately to maintain the watertight integrity of the shower enclosure.
