What's the cost of widening a bathroom doorway for wheelchair access in Calgary?

Widening a bathroom doorway for wheelchair access in Calgary typically costs $1,500 to $3,500, with the final price depending primarily on whether the wall is load-bearing, the type of door you install, and the extent of finishing work required. This is one of the most essential accessibility modifications and has the single biggest impact on whether a wheelchair user can actually access the bathroom independently.

The target width is a minimum of 32 inches clear opening, meaning 32 inches of usable space when the door is fully open. For comfortable wheelchair passage, 36 inches clear is strongly preferred and is the standard specified in the Alberta Building Code for accessible bathrooms in public and multi-unit buildings. "Clear opening" is measured between the door stop on the latch side and the face of the door when open 90 degrees — the rough opening in the framing needs to be about 2 inches wider than the door slab to accommodate the frame.

For a non-load-bearing wall (the most common scenario for interior bathroom walls), the process involves removing the existing door and frame, cutting the drywall wider, removing the studs in the way, installing a new wider header and jack studs, reframing the opening, hanging the new wider door and frame, patching and finishing the drywall, and painting. This work typically costs $1,500 to $2,500 in the Calgary market. If the wall is load-bearing — which is less common for bathroom walls but does occur, especially in older Calgary bungalows and split-levels — a structural header (typically a built-up LVL or doubled 2x10) must be installed to carry the load above. This adds engineering costs ($300 to $500 for a structural assessment) and additional labour, bringing the total to $2,500 to $3,500. A building permit from the City of Calgary is required for either scenario because you are modifying the structural framing, even in a non-load-bearing wall. Permit fees run $75 to $200, and a Safety Codes Officer will inspect the framing before it's covered with drywall.

Door type selection significantly affects both cost and functionality. A standard swing door in a wider frame is the least expensive option but takes up floor space when open — in a small bathroom, the open door can block access to the toilet or vanity. A pocket door slides into the wall cavity and eliminates the swing entirely, which is ideal for tight bathrooms. Pocket door conversion costs $800 to $2,000 on top of the widening work, because the wall cavity must be modified to accept the pocket door frame. A barn-style sliding door mounted on an exterior track is a popular compromise at $400 to $1,200 — it doesn't require wall cavity modification, but it does require wall space beside the opening for the door to slide into.

A few practical details worth noting for Calgary homeowners. If your bathroom has baseboard heating on the wall being modified, the baseboard unit may need to be shortened or relocated — budget an additional $200 to $400 for this. If there is electrical wiring or a light switch on the wall near the doorway (very common), the electrician will need to reroute the wiring around the wider opening — add $150 to $350 for electrical work and a separate electrical permit. Calgary's chinook-driven temperature swings can cause door frames to shift slightly with the house's thermal movement. Use shimming techniques that allow minor adjustment, and choose a door that is not so tight in the frame that seasonal movement causes binding.

This is not a DIY project — framing modifications require proper header sizing, secure connections, and code-compliant construction that will be inspected. Hire a renovation contractor experienced in accessibility modifications, verify their WCB Alberta coverage, and ensure all permits are pulled before work begins.
