How to Plumb Your In-Law or Income Suite

Add A Bathroom

Make sure your in-law suite has at least one full bathroom to make it a comfortable home. Installing a new bathroom is not a DIY job, so you’ll need a professional to put in the new fixtures, including toilet, sink and shower or tub. There are many brands of water-saving fixtures that save money without sacrificing water pressure, so make sure you ask about your options! You will also want your plumber to make sure the drains work properly before anyone moves into your income suite.

Kitchen Appliances

Whether your in-law suite will have a full kitchen or a kitchenette it will need a sink. There are many reasonably priced options that provide great functionality and reduced water usage. If you use gas appliances, you’ll also need gas lines installed to serve the income suite’s kitchen.

Laundry Room

Unless you plan to use it as an AirBnB, your income suite will need laundry facilities. Not only will your in-laws or renters be able to do laundry at their convenience, another laundry room also increases the value of your home when it comes time to sell. This is especially true if you are building a separate structure to serve as your in-law suite, as it saves your family or renter from having to walk over to the main house just to run the washing machine.


Water Heaters

Unless your existing water heater is able to accommodate the additional plumbing fixtures in your in-law suite, you’ll want to add a water heater for the suite’s use. You plumber can help you decide which water heater option is best for your in-law suite; there are several types available on the market, including: 

  • Electric Water Heaters: Low installation cost with a long lifespan.
  • Gas Water Heaters: Faster than electric with a lower utility cost.
  • Tankless Water Heaters: Heats water only when needed, which saves money and energy.
