Shower pans are a thin layer of plastic at the bottom of your shower and several inches up the sides underneath a layer of mortar, called the mortar bed, and then your tile and grout. They are sloped downward toward the center drain of your shower and connect to your shower’s drain system. This helps move any leaks from the tile still drain and not affect the subfloor above your house’s foundation. Shower pans are required to protect your subfloor from leaks, water damage, and eventual rotting. Subfloors are normally made of wood, but even tile and stone subfloors aren’t immune to leaks.
Your shower pan liner is the waterproofing layer. If this leaks, you have a big problem on your hands and have lost a ton of money out of your wallet. Your shower pan is constantly exposed to water and moisture that can make them weak. This can cause extensive damage to not only your shower, but nearby cabinets, your bathroom floor, your shower doorframe, your bathroom walls, and any room that is connected to your bathroom, like closets. Needing to replace any combination of these items can cost you an excessive amount of money.
Detection is key to stop water damage from spreading. Your shower tiles and grout absorb water and can leak. If you have any loose, cracked, or unsealed tiles or your grout is peeling or missing, especially in your shower floor, you may have a leak. This leak can trickle down into the mortar bed, which is a layer of cement like material that supports your shower tile. If the leak gets through the mortar bed and then the liner, your shower pan can leak. This is what causes all of the damage. To properly and reliably repair your shower, the bottom of your shower and at least a couple of inches up the sides, plus anywhere else there might be water damage needs to be demolished.
Sometimes the leak isn’t noticeable in your shower, but you notice that the floor or walls outside of your shower or on the other side of the wall by your shower are wet, you have a shower pan or drain system leak. Drain systems are checked first, since they are easier to detect. If your leak isn’t in the drain system, you have a leak in your shower pan or liner.
Unfortunately construction errors are becoming more common for leaks, like nail holes in the pan liner when installed previously.
