Even if your garage already has electricity, you may still need to budget in the cost to run electricity to a garage to attach plumbing fixtures and appliances (like installing a hot tub and sauna as part of your glamorous revamp).

New Plumbing in Detached Garage or Shed Cost Factors

Costs for attaching plumbing to a detached shed or garage vary wildly because each property layout is dramatically different. The major factors influencing price are usually out of the homeowner's control.

Distance Between the Home and Detached Building

The distance that your new piping will need to travel is the single biggest factor in determining the cost of your project. You could easily pay ten times more if you want to hook up an outcropping on a far part of the yard.

Size of the Building

For example, a bigger shed or garage will warrant more outlets and water pressure you need.

Number of Fixtures Connected

You'll pay per fixture when it comes to installation and hookup costs.

Location of the Pipes

Underground pipes will cost more to install, as will pipes within the walls.

Cost of Materials

The price per square foot of piping that you choose influences total project costs. For instance, copper is more expensive than PEX. Unless you have a background in plumbing or construction, you should consider working with licensed pros when adding plumbing to detached garages or sheds. Laying piping from scratch isn't generally considered a DIY project.

FAQs

Can you put a toilet in a garage?

While adding a toilet to a garage is challenging, it is possible. If your garage has a concrete pad, it's necessary to break through the concrete to install pipes. Another option is to create raised platforms for the toilet, shower, and sink to allow waste pipes to run through your wall before routing underground.

How do you create drainage when adding a bathroom to a sunken garage?

Gravity can make it difficult to make plumbing work in a garage if your plumbing is lower than your drainage point. Plumbers will generally recommend using an upflush system that discharges into a pump from the back of the toilet.

Do you have to pay property taxes on a shed with plumbing?

While tax assessments vary around the country, a shed that connects to water or electrical services is likely to be assessed for property taxes.
