How much does it cost to add a dedicated circuit for a hot tub?

Adding a dedicated circuit for a hot tub in Ottawa typically costs $800 to $1,500, depending on the distance from your electrical panel, the amperage required, and any trenching or conduit work needed.

The cost varies significantly based on several factors. Most residential hot tubs require either a 40-amp or 50-amp dedicated circuit using 8 AWG or 6 AWG wire respectively. If your hot tub is located close to your electrical panel (within 50 feet) and the run is straightforward, you'll be on the lower end of the price range. However, if the hot tub is far from the panel or requires underground wiring across your yard, costs can increase substantially due to trenching and conduit requirements.

Your electrical panel must have adequate capacity to handle the new circuit. A typical hot tub draws 40-50 amps, so if your panel is already near capacity, you might need a panel upgrade first, which adds $2,000-$3,500 to the project. The circuit installation itself includes running the appropriate gauge wire, installing a new breaker, connecting a disconnect switch within sight of the hot tub (required by the Ontario Electrical Safety Code), and ensuring proper GFCI protection.

ESA permits and inspection are mandatory for hot tub electrical installations in Ontario. The permit typically costs $75-$150, and the work must be completed by a licensed electrician. The ESA inspector will verify that the installation meets code requirements, including proper grounding, bonding of metal components, and GFCI protection. Hot tub electrical work is particularly safety-critical due to the combination of electricity and water.

Additional costs may include a concrete pad for the disconnect switch ($200-$400), trenching for underground runs ($5-$15 per linear foot), and any necessary upgrades to your electrical service. If you're installing the hot tub on a deck, special considerations for wire routing and support may apply.

Never attempt hot tub electrical work yourself - the combination of high amperage circuits and water creates serious electrocution and fire risks. Insurance companies may deny claims for unpermitted electrical work, and improper installation can be deadly.
