Basement Bathroom Plumbing


Here we’ll look at what it takes to do the basement bathroom plumbing. At this stage, the basement walls will have been framed in, and now you’re ready to run the feed lines through the framing and have everything connected from your rough-in plumbing to get the rest ready for the drywalling stage.

Basement Bathroom Plumbing

From when we first looked at this series of posts dealing with a basement renovation, one of the first criteria was to plan for the bathroom layout ideas. Once you knew where the bathroom and all the fixtures were going to be placed, the rough in would be done if the basement required anything to be moved or added. From there we would be looking at performing the rest of the installation of running the remainder of the plumbing lines in and through the wall cavities. The video below shows some of the steps by what it takes to install the shower fixture using pex. Depending on where you live, codes can vary, and you may be required to run all copper or other combinations of materials to meet code.

Again depending on the code book for your local area will determine how the fittings will be attached and what type to use. When you hire a plumber to do the work then this should be a none issue as they are certified and should know what they are doing. Like anything else in this world, you want to check around, as even though plumbers are a certified trade, there are some that should not leave the house.

DIY Basement Plumbing

In the case, this is a full DIY project, many places throughout the country allow homeowners to be able to do their plumbing. Make sure you know and understand the requirements from the building code book for the type of plumbing you need to do. When it comes to water, trust me when I say you do not want to have an issue with leaks.
You can do pressure checks which I strongly advise as this is the easiest and simplest way to know how you did with your plumbing. I would also mention that you want to have all your plumbing tested before you decide to close up the walls with any form of wallboard.


Running Hot & Cold Feeds


Running the hot and cold feed lines is pretty straight forward to get them to each fixture you intend to have, the key thing is having all the right and proper fittings and making sure you have them well connected so there will be no problems later. Again the pressure test will take care of determining if you have any issues with your connections.

The other and critical issue are the drain lines. You will need to have the proper grade for the water to run and exit through the pipes correctly. You will need to make sure you have the right connection to the stack and have the appropriate ventilation with the stink pipe to ensure that you have proper flow movement which will also be mentioned in the code book.
All sinks, tubs, and showers will have the appropriate P-traps installed. The toilet has one built in, but some places may require you to have a second P-trap in the line. Even where I live this second, one is no longer needed in residential homes anymore.

Running Drain Lines


A major safety issue that you need to consider whenever you are running drain lines is not to cut into structural floor joists and load bearing walls as to cause a problem with the integrity that they are designed for with excepting load. The builders code book for plumbing will let you know what you can and can not do in these circumstances. I’ve run into too many circumstances as a contractor with TD Remodeling where other contractors have plumbers cutting notches out of the floor joists taking away their integrity for toilet waste lines instead of rerouting the lines direction or having a bulkhead installed.

When it comes to home renovation how to for basement bathroom plumbing, you should never take short cuts to save money or create what you may think is a better design appearance because the alternative may be the floor or ceiling above come crashing down. Now It’s going to cost money to fix something that never should have happened. If you do your own plumbing make sure you know the code for your area to avoid all and any problems from happening in the near future.
