A properly draining shower drain is an essential part of your bathroom: clogs can quickly cause water damage and flooding in your bathroom, not to mention cause a great deal of stress in your plumbing system. Even in the absence of a full clog, a slow draining drain will make it much less comfortable to take a shower, since water will be pooling around your ankles. Fortunately, there are a few things that you can do to proactively prevent clogs from occurring in your shower drain.
One of the most important, and also one of the easiest, things that you can do to prevent debris from entering your shower drain where it can slowly build up into a full clog is to install a strainer over a drain. These are made out of fine mesh and can be found at most hardware stores: they are small enough to filter out hair, lint, and other small pieces of debris which may seem inconsequential on their own, but which can contribute to significant blockages in the future.
Another thing that you can do to reduce the risk of a clog developing in your shower drain is to make sure that you always use hot water when you shower. This is because soap scum, shampoo, and other greasy items can solidify in your plumbing, creating a hard blockage that can make your drain less effective at draining water. Hot water will melt through this blockage and allow for a more effective and efficient flow.
Brush Your Hair
Hair is one of the leading causes of shower drain clogs. This is because while individual strands of hair are very small, they are also extremely durable and hard to break, and when they tangle up into a ball, they can create a very durable and resilient clog that can ruin the effectiveness of your drain. While a strainer, as discussed above, can keep hair out of your plumbing, you may also want to consider brushing your hair before you get the chance to get in the shower - this ensures that your strainer won't have to be cleaned out as often and that fewer, if any, hairs actually find their way into your plumbing.
Finally, another thing that you can do to prevent a full-on clog in your shower drain is to pre-emptively clean the drain. You have two main options: using a drain snake to remove any hair and break up any other blockages, or hydrojetting, which uses high pressured water to accomplish the same thing in much less time and with much less effort - though at a higher cost, since it requires a professional to do it for you. Avoid making use of drain cleaning solutions, which can eat away at the structural integrity of your pipes and can make a leak more likely in the future.
