  1. Choose a design

    The new basement bathroom needs to be as close as possible to the electrical wiring and plumbing. Next, decide if you want a bathtub or a bathtub and shower combination. Keep in mind that basements are chilly. Consider adding a heating system. To avoid moisture, add a ventilation fan.

  2. Calculate the plumbing depth and pipe size

    One of the most important considerations when building a bathroom is the drainage. The plumbing depth should be deep enough. Larger pipes are also ideal for the basement.

  3. Choose a toilet system

    There are several toilet systems to choose from including pressure-assisted toilets, up-flushing toilets and composting toilets. You can also choose to install a sewage-ejector system. This type of system sends the pump sewage to the septic tank line. The sewage-ejector systems are either above-ground or below-ground.

  4. Choose a lighting type

    Most basements do not have any natural light. This is why adding some strong lights is a good idea. Aside from being waterproof, lights over showers and bathtubs have to be vapor-proof.
