Do you need help hooking up a stackable washer/dryer set? Washing machines tend to stop working far sooner than dryers, but maybe you’re considering installing a stackable set instead of purchasing separate pieces.

Let us answer some common questions for you before you decide on installing a washer/dryer combo.

How do I Know if a Stackable Washer/Dryer Set Will Fit into an Existing Space?

Washing machines, dryers, and washer/dryer sets all come in a variety of sizes. You’ll be fine if both your old and new appliances are the same size. Nonetheless, you should always check the specs of your appliances before you order or measure and compare your existing washer/dryer to the new one before you order.

Of course, if you have your current washing machine and dryer placed in a location without a cabinet surrounding them, you don’t have to worry too much about a few inches here and there. You can always call our specialists at Fite Plumbing to take measurements for you, or if you live in an apartment, the maintenance staff may be able to help as well.

Additionally, consider asking an associate at the appliance store to do an on-site inspection before they deliver. (Don’t forget to always ask what a big box store charges for this inspection so you aren’t surprised with a bill.)

Standard Washing Machine and Dryer Sizes

It’s probably helpful if you have a little bit of context for the size of typical washing machines and dryers. Here are the most common industry measurements.


Top-loading and front-loading washers and dryers measure 27 inches wide, 27 to 28 inches deep, and 34 to 43 inches high. Top loaders that have control panels on top can be pretty tall.


Compact appliances are usually 21 to 24 inches in width, 22 to 24 inches in depth, and 33 to 34 inches high. Hooking up these washer/dryer sets are convenient for people without much space. The most versatile compact dryers are ventless dryers since they don’t require outside venting.  It’s also possible to stack a dryer on top of a front-loading washer to save space. (Always check with a Fite Plumbing expert to ensure safety, especially if you have a gas hookup.)

Stackable Washer/Dryer

The stackable washer/dryer set gives you all the benefits of two appliances in the compact conveniences of one. In fact, The footprint of a stackable washer/dryer combo is half that of a side-by-side appliance. The width could be 24 or 27 inches, but the height could be 72 to 78 inches.


Alternatively, you can buy a combination washer/dryer that does both washing and drying. This combination appliance is designed for small spaces so that it can be installed in a kitchen or bathroom. No exhaust duct is required, and the dryer can be plugged into a standard 120V outlet.

Do I Need to Upgrade My Plumbing?

If you’re getting a new stackable washer/dryer set or a side-by-side appliance, you’re probably wondering if you need to upgrade any wiring or plumbing.

Consult an electrician or Fite Plumbing provider if you aren’t sure what changes are required. Whether you’re downsizing to a stackable washer/dryer set or upgrading full-size appliances, you might need to upgrade your plumbing and electrical system.

Things to Consider

If your plumbing arrangement meets code, you probably won’t need to make any changes.

  • Standard 120-volt outlets are sufficient for most washers.
  • One-piece stackable washer/dryer units save space in a small apartment.
  • Electric dryers require a special appliance cord with a four-prong plug that must be connected to a 120/240-volt outlet.
  • Stackable washer/dryer sets need to have enough space above them since they can be stacked up to six feet.
  • Stackable appliances require the same wiring, plumbing, and venting as a traditional set.
  • Electric dryers require their own 240-volt circuits, but gas dryers can share a 120-volt circuit with the washer.
  • Electric outlets should not be installed close to drain hoses and water lines for the washer.
  • A screen should never be installed at the dryer vent’s outdoor end. If not removed, the lint will clog the vent.

Additionally, you may wish to upgrade the supply hoses to stainless steel braided connections to avoid leaks or add a drip pan under the washer to prevent leaks.


And finally, you might be wondering what to do about your old washing machine and dryer. Fortunately, most retailers offer to pick up your old machines when they drop off your new ones.
