Do I need a permit to install a shower where there was a tub?

In most cases, no - replacing a tub with a shower in the same location typically doesn't require a building permit in Ottawa, as long as you're using the existing plumbing rough-in and not moving any walls or electrical.

This type of bathroom update is generally considered maintenance or minor renovation work. You're working within the existing "footprint" of the bathroom, using the same water supply lines, drain location, and electrical circuits. The City of Ottawa Building Code Services doesn't typically require permits for fixture replacements that don't involve structural changes or new rough-in work.

However, there are important exceptions where permits become necessary. If you're moving the drain location, adding new electrical circuits for features like steam showers or multiple body sprays, or removing/relocating walls, then you'll need building permits. Any electrical work beyond simple fixture swapping requires permits through the Electrical Safety Authority (ESA). For example, if you're adding a new exhaust fan circuit, installing heated floors, or upgrading the electrical panel to handle additional load, you'll need electrical permits.

The plumbing considerations are equally important. While you don't need permits for the fixture swap itself, any modifications to the plumbing rough-in do require permits. In Ottawa's older homes (pre-1960s), you might discover galvanized steel pipes that need updating, or find that the existing drain can't handle a modern shower's flow rate. These situations would trigger permit requirements.

From a practical standpoint, most homeowners can handle the demolition of the old tub, but the plumbing connections should be done by a licensed plumber to ensure proper installation and avoid future leaks. The waterproofing behind the new shower surround is critical in Ottawa's climate - any moisture intrusion can lead to mold issues or structural damage during our freeze-thaw cycles.

Your next steps should include confirming that your existing plumbing can handle the new shower configuration and ensuring proper waterproofing installation. If you're unsure about any electrical or plumbing modifications needed, it's worth having a professional assess the current setup before starting the project.
