Can we put a shower in the basement if we only have rough-in for a toilet?

Yes, you can absolutely add a shower to your basement even with just a toilet rough-in, but it will require additional plumbing work and potentially some concrete cutting. This is a common scenario we see in Ottawa basements where builders initially only stubbed in the basics.

What's Involved in Adding the Shower

Your existing toilet rough-in gives you a good starting point since the main drain line is already there. To add a shower, you'll need to tie into this existing drainage system and run new supply lines for hot and cold water. The shower drain will need to connect to your existing waste stack, which typically means cutting into the concrete floor to install the new drain line and P-trap.

The complexity depends on where you want the shower relative to your existing toilet rough-in. If they're close together (within 6-8 feet), the plumbing work is more straightforward. If you're placing the shower across the room, expect more extensive floor cutting and longer drain runs. In Ottawa's older homes with concrete floors, this work requires careful planning to avoid existing utilities and maintain proper drainage slopes.

Ottawa Building Code and Permit Requirements

Adding a shower requires a plumbing permit through the City of Ottawa, especially since you're modifying the drainage system. The Ontario Building Code requires proper venting for the shower drain, which may mean extending your existing vent stack or adding a new one. You'll also need to ensure adequate ceiling height - minimum 6'8" over the shower area.

Professional Requirements and Costs

This work must be done by a licensed plumber in Ontario, as it involves modifications to your home's drainage system. Electrical work for lighting and ventilation (required in shower areas) needs ESA permits and a licensed electrician. Expect costs of $2,500-$5,000 for basic shower plumbing addition, plus electrical work ($500-$1,200), not including the shower unit itself or finishing work.

Next Steps for Your Project

Start with a consultation from a licensed plumber who can assess your existing rough-in and determine the best approach for your shower placement. They'll need to locate your existing drain lines and plan the new connections.
