Plumbing Your Basement Project

This article is the third installment by Kitchen Connections, evaluating the considerations for finishing your basement.

Basement Bathroom

It is reasonable to assume that adding a bathroom is a high priority if you plan to finish your basement. After all, when nature calls, you do not want to go upstairs to find a bathroom. Additionally, you can add a bar, a kitchen, a laundry room, or all three. Addressing the plumbing issues required by your basement finishing plan may be your first significant activity. If you built your house in the last twenty years, your builder may have roughed the drainage pipe for future development. Paper or rags may have been stuffed into this pipe opening to minimize gas and unpleasant odors emanating from the roughed-in drain pipe. Additional drainage needs will likely connect to that pipe. Addressing drainage and water supply is an important place to begin your work.

Our basement project created a 750-square-foot, one-bedroom, walk-out apartment. It includes a full bathroom, a laundry room, a great room, and a kitchenette. This space is not just for guests but also for our children and grandchildren or even as a rental. The plumbing for both the kitchenette and the laundry room was simple, allowing us to focus on the exciting aspects of personalizing our new space.

If you plan to add a shower or a bath, you may still need to cut the concrete of your basement foundation. We had to break concrete to connect the future shower drainpipe to the roughed-in connection to the main drain. With that task completed, we connected the vanity sink to the shower drain. Typically, drainpipes for a basement vanity, shower or bathtub, and toilet are not installed during the construction of a new house. The typical rough-in for a basement bathroom is limited to the drainpipe for the toilet. There is only a need to incur this cost on a new home if finishing the basement is a certainty. Drainage for the vanity and shower must be added. Expect to cut and bust some concrete to build your basement bathroom.

After completing our basement bathroom, we found water drained slowly and backed up in the shower. We had to clear a blockage. Our plumber cleared the paper from the drain, which resolved the issue. We have yet to experience further drainage issues.

It is essential to ensure pre-plumbed drainage pipes are connected to the main drain without obstructions. I remember a YouTube video I recently viewed. In this video, a New Jersey couple was filmed with their contractor while planning to finish their basement. The house was new, and the builder had planned for a basement bathroom. At least it looked like he had done so, as a PVC pipe rose from the foundation. Upon further inspection, the contractor discovered that the pipe was only stuck in the foundation and not connected to the main drain. I had to laugh. It seems appropriate for New Jersey. Did the building inspector miss this violation, or was it something else? The homeowners were not happy. It required them to cut into the foundation to build a trench and lay pipes to connect to the main drain. I wonder if the homeowners factored this cost into their budget. Finding and connecting to the main drain is the priority. One must budget for this cost.

Another consideration is to use copper pipes, the Pex System, or maybe PVC for the water lines. Each has its advantages and disadvantages. Copper is reliable but expensive. Pex and PVC are less costly and easy to install but may only be suitable for some locations. There is a lot of information on the internet to help you decide which of these options is the best for your project. Our situation was ideal for installing a Pex System. You will want to research this issue to determine the best solution.

CONCLUSION:
The plumbing required for finishing your basement is a significant consideration. It is a large component of the cost for most basement remodel projects. If you plan to do some or all the work yourself, you can save a lot of money. However, it will require a significant investment in your time. If you are required to have a building permit, the situation will become more complicated. There are several options to consider regarding connecting to the water supply. Each has benefits and disadvantages, so choose the most suitable option.
