Can I convert a single vanity to a double vanity in my Okotoks bathroom?

Yes, converting a single vanity to a double vanity in your Okotoks bathroom is a very popular upgrade, but it requires adequate wall space (minimum 60 inches, ideally 72 inches), new plumbing rough-in for the second sink, and typically an electrical permit for additional outlet placement. This is one of the most common bathroom upgrades in Okotoks homes, particularly in the master ensuites of the town's many 2000s-era builds where builder-grade single vanities no longer meet growing families' needs.

The space requirement is the first thing to assess. A functional double vanity needs at least 48 inches of width at the absolute minimum, but 60 to 72 inches is far more comfortable and practical. Each sink needs roughly 30 inches of counter space to feel usable — anything less and you will constantly bump elbows. Measure your available wall space carefully, accounting for the door swing, toilet clearance (minimum 15 inches from the centre of the toilet to the vanity, per Alberta Building Code), and any obstructions like ductwork or electrical panels. Many Okotoks homes built in the Cimarron, D'Arcy, and Drake Landing communities have master ensuites with enough wall space for a 60-inch double vanity where a 36-inch single currently sits.

Plumbing work is the most significant part of this conversion. Your existing single vanity has one set of hot and cold water supply lines and one drain connection. A double vanity requires a second set of supply lines and a second drain tie-in. A licensed plumber will need to tap into the existing supply lines and extend them to the second sink location, then install a new drain that connects to the existing drain stack. This plumbing work typically costs $800 to $1,500 in the Calgary-Okotoks area depending on accessibility — if the wall behind the vanity is open (as in a renovation where drywall is already removed), costs are lower. If the plumber needs to cut into finished walls, costs increase for drywall repair and finishing. Because you are adding new plumbing connections, a plumbing permit is required through the Town of Okotoks, typically costing $75 to $200. A Safety Codes Officer will inspect the rough-in before the wall is closed up.

The total cost for a single-to-double vanity conversion in Okotoks runs approximately $3,000 to $7,000 depending on your choices. Breaking that down: the double vanity cabinet itself costs $800 to $3,500 depending on whether you choose stock or semi-custom, the quartz countertop with two sink cutouts runs $600 to $1,500, two new faucets cost $160 to $800 total, plumbing rough-in and connection adds $800 to $1,500, an electrical outlet addition or relocation runs $200 to $500, and finishing work including drywall repair, paint, and a larger mirror or two individual mirrors adds $300 to $700. Installation labour for the vanity, countertop, sinks, and faucets runs $350 to $800 on top of the plumbing costs.

Calgary's hard water is an important consideration when selecting your double vanity components. With two sinks seeing daily use, hard water deposits accumulate twice as fast across a wider surface area. Choose brushed nickel or matte black faucets rather than polished chrome, and opt for a quartz countertop that resists hard water staining without sealing. A lighter quartz colour with subtle veining hides water spots better than solid dark tones.

The conversion is not a DIY project — it involves licensed plumbing, likely electrical work, and potentially structural considerations if your wall needs reinforcement for a heavier vanity.
