Basement Bathroom Rough-In in Burlington

When you need basement bathroom rough-in

Finishing a basement for a teenager, a guest suite or a family member nearly always includes a bathroom. If you see capped pipes sticking up from the floor, often near the stack, the builder planned ahead for a three-piece washroom. If there are none, the floor must be cut to connect new drains to the main line, or a pump-up system used where the main is too shallow.

How the job is done

1. Confirm what exists. We identify each capped pipe, check it with a camera if needed and confirm a vent was provided.
2. Lay out the room. Fixture positions are set to suit both the existing pipes and the room you want.
3. Open the floor. Where new drains are needed, a trench is saw-cut, the pipe laid at the right slope on proper bedding and tested.
4. Vent and supply. Vents are tied into the existing system and supply lines are run from the nearest branch.
5. Inspect and pour. After inspection, the trench is filled and re-poured.

Where gravity drainage is impossible, a sewage ejector pit or a macerating toilet are options; each has trade-offs we will explain.

Burlington homes and this work

Subdivisions from the late 1980s onward, including much of Millcroft, Orchard and Alton Village, commonly have a three-piece rough-in. Older bungalows in Mountainside, Dynes and Longmoor usually do not. In flood-prone areas, a backwater valve should be part of any new basement bathroom plan, since a lower-level toilet is the first fixture to overflow in a sewer backup.

What affects the scope

• Existing rough-in versus new drains in the slab
• Distance from the main stack
• Gravity drainage or a pump system
• Water heater capacity for an extra shower

Before we arrive

Move storage away from the stack and the capped stubs. Have a rough sketch of the room with wall locations. Look at backwater valve installation before you finalise plans.
