Installing a Basement Bathroom: What You Need to Know

Jan 19, 2018 | Blog | 0 comments

One of the more common topics we answer questions about for our clients is installing a basement bathroom. Whether the project is for a legal secondary suite, or simply for homeowners looking to make the most of their space, adding an extra bathroom to your downstairs area can be a great way to add extra value.

Compared to their upstairs counterparts, these rooms require a little extra planning. If you’re considering new bathroom addition to your basement, here are a few factors you’ll want to keep in mind.

Know What Kind of Bathroom You Want

Before you start looking for a contractor and drawing up plans, you’ll need to decide what kind of bathroom you want. If the addition isn’t for a legal suite, you may want to consider a ½ bathroom opposed to a full. Showers and bathtubs add extra moisture to a space that already tends to be cool and damp, leaving more room for potential damage in the long run. If you’re set on a full bath, you’ll need to make sure you take excess humidity into account and work to prevent mould build-up or water damage.

Placement Matters

To make things easier, you’ll want to do your best to have your addition placed close to any existing plumbing groundwork.

Know Your Drainage Set Up First

This a crucial element to any bathroom renovation, but especially for below “grade” units. Where above grade washrooms have the benefit of gravity, basement bathrooms need to be located properly to work with existing plumbing drainage lines. There are two main components to this that your contractor will want to evaluate: pipe size and plumbing depth, both of which play an important role in drainage. You’ll also want to determine the flow rate, and if you’re connected to a city sewer line, you’ll need a backwater valve to prevent sewage backup and to meet current code specifications.

These are only a few of the basic elements you’ll want to consider when it comes to basement bathroom planning. To learn more, or to get started on your project, contact us today!
