How much does it cost to build a pet washing station in a GTA basement renovation?

A pet washing station in a GTA basement typically costs $3,000–$8,000 installed, depending on the size, finishes, and whether rough-in plumbing already exists near the location.

This is one of the more popular add-ons in GTA basement renovations right now, especially in homes with large dogs. The core of the project is essentially a deep utility sink or custom tub with hot and cold water supply, a drain connection, and a handheld sprayer — but the final cost swings significantly based on how far your plumber needs to run new supply and drain lines, and how custom you want the surround and cabinetry to go.

What Drives the Cost

Plumbing is the biggest variable. If your basement already has a rough-in nearby (near a laundry area or existing bathroom), connecting a pet wash station is relatively straightforward — a licensed plumber can tie into existing supply lines and the drain stack for $1,500–$3,000 in labour and materials. If there's no nearby rough-in, the plumber needs to break the concrete floor to run a new drain line to the stack, which adds $2,000–$4,000 to the plumbing scope alone. This is work that requires a licensed plumber and a plumbing permit — not a DIY item.

The tub or basin itself ranges from a basic stainless steel utility sink ($200–$500) to a purpose-built elevated dog wash tub with ramp access ($600–$1,500). Elevated tubs are worth the investment if you have a large breed — bending over a floor-level tub in a basement gets old fast. Tile surrounds, custom cabinetry, and built-in storage for shampoo and towels can add another $1,000–$3,000 depending on finishes.

Waterproofing the immediate area matters more than most homeowners expect. The floor and walls around the station need to be tiled or covered in a waterproof material — LVP is fine for the rest of the basement, but the splash zone around a pet wash needs ceramic or porcelain tile with properly waterproofed seams. Budget $800–$2,000 for tiling the immediate area, depending on tile selection and square footage.

GTA-Specific Considerations

In older GTA homes — particularly post-war bungalows in Scarborough, North York, and Etobicoke — the existing drain stack is often cast iron and may need a transition coupling to connect new PVC drain lines. Your plumber will assess this during the estimate. Also, if your basement bathroom or laundry room is on the opposite side of the basement from where you want the pet station, the cost of running new drain lines under the concrete floor can make the project significantly more expensive. Locating the pet wash station adjacent to an existing wet area is the single best way to control plumbing costs.

Basement humidity is already a concern in GTA homes during summer — a pet wash station adds another moisture source. Make sure your contractor includes a properly vented exhaust fan in the area (vented to the exterior, not into the soffit), and that the drain has a proper trap to prevent sewer gas from entering the finished space.

Practical Tips

Position the station near a floor drain if one exists. Keep the hot water run short — long runs mean waiting for hot water and wasted water. A thermostatic mixing valve ($200–$400) is a worthwhile upgrade so you can pre-set a comfortable water temperature without scalding your pet. If you're finishing the basement at the same time, have your plumber rough in the pet wash station at the same time as the bathroom — combining the trades visits saves mobilization costs.

All plumbing work requires a permit and inspection through your local municipality. The City of Toronto and GTA municipalities take plumbing permits seriously, and unpermitted drain connections under a concrete slab are a problem when you eventually sell.
