How much more expensive is it to add a kitchenette to a basement versus just a wet bar?

Adding a full kitchenette to your basement will typically cost $15,000-$35,000, while a wet bar ranges from $3,000-$12,000 - so you're looking at roughly 3-5 times the investment for a kitchenette versus a basic wet bar.

The significant cost difference comes down to complexity and code requirements. A wet bar typically includes a sink, some storage, and basic plumbing connections - relatively straightforward work that can often tie into existing plumbing lines. You're mainly dealing with cabinetry, countertops, a sink, and potentially a small refrigerator space.

A basement kitchenette, however, requires much more extensive work. You'll need dedicated electrical circuits for appliances (refrigerator, microwave, potentially a cooktop), which means pulling new 20-amp circuits from your panel. The plumbing becomes more complex too - you'll likely need both supply and drain lines for a sink, plus potentially a gas line if you're installing a gas range. Ventilation requirements also kick in with a kitchenette, especially if you're adding cooking appliances, which may require exhaust fans and makeup air considerations.

In Ottawa specifically, building permits become a major factor. A simple wet bar might not require permits if it's just adding a sink to existing space, but a kitchenette often triggers permit requirements, especially if you're adding new electrical circuits or gas lines. If this kitchenette is part of creating a secondary dwelling unit, you're looking at full building permits, fire separation requirements, and compliance with Ontario Building Code standards for rental units.

Code compliance costs add up quickly with kitchenettes. You may need fire-rated drywall between units, proper egress windows if this is becoming a rental suite, and upgraded electrical panels if your current service can't handle the additional load. These requirements don't apply to a simple wet bar.

The timeline difference is substantial too. A wet bar might take 1-2 weeks to complete, while a kitchenette project often runs 4-8 weeks when you factor in permits, inspections, and the coordination of multiple trades (electrical, plumbing, potentially gas).

Professional guidance is essential for kitchenettes since they involve multiple trades and code requirements. Electrical work requires ESA permits and inspections, and gas connections must be handled by TSSA-licensed technicians. A wet bar might be partially DIY-friendly for the handy homeowner, but kitchenettes really need professional coordination.
