What a rough-in includes
- Drains for the toilet, shower or tub, and vanity, set in the floor at the right heights and locations for your layout
- The tie-in to your existing building drain under the slab
- Venting so fixtures drain freely and traps don't siphon
- Water supply lines to each fixture location, capped for finishing
- Permit and inspection
- Concrete re-poured around the new drains
When your drain is higher than the basement floor
In some older Ottawa homes the sewer line leaves the house high on the foundation wall, so a basement toilet can't drain by gravity. Then a sewage ejector pump (or a compact upflush system for smaller spaces) lifts the waste to the main drain. We'll tell you which one your house needs after we look at where your sewer exits.
Older home? Check the drain while the floor is open
If your building drain under the slab is original cast iron or clay, a rough-in is the right time to camera it. Tying a new bathroom into a failing pipe is a mistake you only find out about after the tile is down. Many of our rough-in customers replace the old drain at the same time and save cutting the floor twice.
Planning a basement bathroom?
Send us your layout. We'll tell you what the plumbing involves and what it costs, before your contractor starts.
Working with your contractor
We work with renovation contractors all the time. We'll meet on site, mark the fixture locations against your plan, and schedule around framing and inspections. If you're managing the renovation yourself, we'll tell you exactly what needs to happen before and after our visit.
Cost
A rough-in is priced on the number of fixtures, the distance to the existing drain, how much concrete is cut, and whether an ejector pump is needed. You'll get a written price once we've seen the space.
