Racking up the Benefits
Adding a new bathroom to your home is a good investment, not only because of the added convenience factor of having another bathroom but also because if you decide to sell your place, you can typically recuperate about ninety percent of your initial investment.
Size, drainage and ventilation are all areas that you must consider when planning your basement renovation project.
Additionally, most of the time when you add an extra bathroom to your house, it will likely will be in your basement. This can be seen as a benefit because a basement bathroom doesn’t have to be as large as your main one especially if you are only adding a sink and toilet, then the room can be as small as 30 x 75 inches.
If you want to add a sink, toilet and shower then a 5 x 7 feet space is adequate. And with most basements having pipes and ducts, an 84 inch ceiling height is a good choice.
Just remember that the most important thing about a basement bathroom is locating vent stacks and drain pipes. This can sometimes be a problem because you may have to dig up the basement floor in order to access the main drain.
Since the distance a fixture must be from the existing drain pipe also comes into play this too must be taken into consideration and any extension to the line must slope down at a minimum of ¼ inch per foot. Don’t forget you must also tie new drains into the current vent stacks.
An Alternative Without the Plumbing Woes
If you have been thinking about this for a while but don’t know where to begin, you should consider talking to a builder, licensed plumber, architect or even a professional at Home Depot or Lowe’s could steer you in the right direction.
I know you’re all gung-ho about the whole thing but its not a good idea to start until you get a full estimate about time and cost from a professional.
An alternative to digging up your basement floor is purchasing a sewage ejector system which is essentially a holding tank attached to an electric pump. This allows you to pump sewage up to the main house drain via a pipe extension and they cost about $700-$1500, the Saniflo system being a prime example.
If you have a shower in your basement bathroom don’t forget to add a ventilation system because we all know that bathrooms produce a lot of humidity. You’ll need the advice of a contractor or cooling and heating professional on how to set up your duct work.
Things you should consider is size of the ventilation fan and whether or not you have a lot of ducts with several turns because this creates airflow resistance which will require a stronger capacity fan.
The main advice here is to seek professional help to make sure you know what you are doing before you begin even if you are going to be doing the majority of the work yourself.
Proper planning will save you money as well as headaches later on when you have to tear down a wall to redo something. Its all doable just be sure you know what needs to be done before you begin.
