Shower pan installation sounds like it should be a pretty easy project to take on but there are a number of steps that must be completed correctly to prevent the appearance of leaks in the future. If you are replacing or remodeling your shower it is a good idea to replace the existing shower pan. This is especially true if you have a ceramic tile shower as they are prone to leaks and water saturation.
If you do not feel like you have the experience or knowledge to properly replace your shower pan and shower, call in a licensed plumber to do the job for you.
One very easy thing to overlook when installing a new shower pan is the grade of the sub-slope above your subflooring. After all, the idea is to get the water to run down the drain instead of sitting in one spot. And let’s face it; by the time you take a shower and see standing water when you turn off the spout, it’s far too late to correct the problem cheaply or easily.
Another very important part of the shower pan installation is installing a good shower pan membrane. These are available in a number of different materials and are the last line of defense from water damaging your subfloor and what lies beneath. It is important that the membrane liner laps up the side of the shower walls a good nine inches.
A second important part of proper shower pan installation is the installation of weeping holes. These weeping holes allow accumulated water or moisture to drain instead of sitting outside the drain. If you do not install a weeping hole or use the incorrect materials, your weeping holes will become blocked over time. This will increase how quickly your shower pan will fail.
If all of this sounds too complicated, call a plumber.
