Portable Washing Machines: How to Buy & Use + 3 Easy Installation Tips

Tips for buying, installing and using a portable washing machine in an apartment or tiny home + bonus tips for efficient clothes drying without a dryer

When I lived in downtown Seattle my apartment building shared a total of two basement washers, two dryers, and zero elevators. This, combined with living on the third floor of a very high-ceilinged 19th-century building made laundry day a dreaded task. Laundry day meant lugging laundry down several floors only to find the washroom busy and having to carry laundry back up- multiple times. This, combined with a dryer that ate my favorite shirt, sent me in pursuit of an alternative for washing my laundry in an apartment.

To be honest, I didn’t even know portable washing machines existed until a friend mentioned they’d recently bought one. Delighted to find they were, in fact, “a thing,” I ordered one immediately.

How I learned about portable washing machines: With my original washer shopping motivated only by getting one at the lowest price, I ended up with an absolute garbage can of a washer. After replacing it with a much better model– with a bit higher price tag – I decided to write this article for other apartment, tiny home, or RV tenants researching portable washing machines.

First, Understanding how portable washing machines work:

Full-size washers are connected to existing plumbing and have a water inlet, where water enters, and a drain. Portable washing machines perform the same function but with temporary plumbing- inlet valves with nozzles that fit onto a garden hose or shower head (with shower head uncrewed- this is my preferred method of installation- read on for DIY) and a drain hose that can be placed into a sink, washtub, bathtub, or- if used outdoors- the ground.

Things to look for when purchasing a portable washing machine:

After trying a few portable washing machines in my third-floor walk-up Seattle apartment, here’s my advice on what to look for in a portable washing machine and why:

One drum or two?

Cheaper portable washing machines have side-by-side drums – one for washing and one for spinning the clothing dry. The user must manually lift heavy, dripping, water-saturated clothing from the washing drum into the spin drum. This is a very wet job as well as an extra task you’ll need to attend to manually. Higher-end portable washing machines- such as Black & Decker’s Portable Washing Machine combine this function into one drum, mimicking a typical wash cycle of a full-sized unit.

Before buying and trying a two drum washer, I didn’t realize that two-drum washing machines do not clean clothes as well because clothing enters the “rinse cycle” while still fully saturated with dirty water. To get clothing really clean, the user must move clothes to the spin drum, then back to the wash drum for a second wash. Using a double-cycle like this to get my clothes clean quickly burned out the motor on the Pyle portable washer I first purchased.

It's worth investing in a one-drum washer for convenience.

Inlet valve or manual fill?

Some portable washing machines require a manual filled for each wash or rinse phase of a wash cycle. These machines are only slightly easier than manual handwashing, as they require attention throughout the cycle and, most likely, a willingness to get a little wet. Good machines will have an inlet valve to which you can screw on a hose so the machine will automatically fill with the right amount of water at each phase of the cycle.

Gravity drain or pump drain?

Having used several portable washing machines, the most important feature to me is a pump drain. Gravity drains empty very slowly and only work when the hose can be placed on a downward incline. Pump drains work quickly to empty water from a hose at any angle, allowing a wash cycle to be completed sooner.



Hacks for setting up a portable washing machine:

Follow your manufacturer’s instructions for installation as a primary guide, but these two modifications may help improve the function and ease-of-use for your machine:

1. Upgrade your shower to a handheld showerhead, then use the same hose for filling your washing machine.

Guys, this is a game-changer, an absolute essential, and the first modification I make to the shower in any apartment I move into:  Swapping from a wall mount shower head to a handheld is so cheap and literally just takes three minutes and no tools. The #1 handheld shower head on Amazon (which is the one pictured in this post) costs less than $25. Once you’ve upgraded to a handheld showerhead, the included hose makes it easy to connect to your washing machine in a convenient location whenever you need to wash a load of clothes in your washing machine.

how to attach a portable washing machine to a shower head

You’ll probably need to purchase an adapter to couple the showerhead hose and the washer inlet. To connect a standard handheld shower hose to the vast majority of portable washers (they tend to be threaded for garden hose connections), you’ll need a 3/4″ MGH x 1/2″ MPT Adaptor (MGH = male garden hose, mpt = male pipe thread).

You can get a brass one at amazon via this link, or, if you are lucky, you might be able to find a plastic version at your local hardware store for a lower cost (Amazon doesn’t seem to stock the plastic version, and big box home improvement stores almost definitely won’t carry this unusual pipe adaptor in any material).

2. Experiment with drain hose placement

Your mileage may vary depending on your washer model, but my Black & Decker portable washing machine functions much better when the drain hose is placed up high.  While gravity-draining models require the hose to be placed lower than the unit for best results, some pump-drain style washers need to be placed up high in order to prevent draining prematurely due to excessive pressure on the valve.

The drain hose needs to be placed in a position where it won't shift when water is pumped through it at velocity. Using a resistance band to hold mine over the tub, with tension, keeps the water draining safely over the tub

For Drying Clothes:

If I get a portable washer do I also need a portable dryer?

Definitely not! It’s uniquely North American to view a washer and dryer as an essential pairing. There are so many easy and energy-efficient ways to dry clothes without using a dryer (even in the winter) and it’s SO much better for your clothes!

Here are the dryer methods that I’ve used and liked. The perfect one for you will depend on your living situation and what you have access to:

Retractable clothesline

A retractable clothesline is the simplest and also the most aesthetically appealing option for drying clothes without a washer. I love this one so much that I’ve uninstalled, moved with it, and reinstalled it 3 times in the last 10 years! With a section mounted on each side of a room, the retractable clothesline allows you to pull the necessary length out and attach it to its counterpart across the room, creating a clothesline when you need it and free space when you don’t. Retractable clotheslines work best to dry clothes when installed in a bathroom with an exhaust fan.

Travel clothesline

You guys have heard me rave about Lewis N Clark products on my travel posts, but I love their travel clothesline because the tiny gaps in the stretchy braided cord allow it to be used without clothespins- just tuck a tiny corner of the fabric into a gap and the tension will hold it secure. Surprisingly strong suction cups keep this mounted on a variety of services- This model was my go-to when I spent three months in South America last year.

Pants Hanger

these were very popular in decades past, and honestly all three of the pants hangers I own I purchased from vintage shops (you can get vintage ones like via these listings on Etsy). They are ideal for small locations and for maximizing drying space in a vertical direction. I also like that unlike many products FOR drying clothes- they aren’t single-use. They’re technically designed for hanging skirts but I love them for organizing scarves and accessories. Another bonus of this style of drying rack is that the hanger is ideal for situations where you might need to dry clothing in an open window- clips keep garments secured even in a strong breeze.

Dryer rack

Somewhat common and perhaps something you already own for drying sweaters, dryer racks take up a lot of floorspace when in use but have only a tiny footprint when folded up. They’re great for drying an entire load quickly. Because they’re portable, they can be used inside or outside.


How to avoid humid air when drying clothes indoors.

The trick to drying clothes inside without creating a swamp-air microclimate is ventilation. Consider how air is entering and exiting the room where you are drying clothing. You can either swap wet air for dry (using a fan + open window, or an exhaust fan) or dehumidify (with a heater or a dehumidifier) to keep your living space comfortable while drying clothes indoors.  Here are a few tips:

  1. Manually adjust your wash cycle to force the machine to spin the load as long as the settings will allow.
  2. If using in a bathroom, turn on the exhaust fan
  3. If air outside is a tolerable temperature, open windows.
  4. Set up a fan blowing on the wet clothes
  5. Run a space heater in the area (heaters dehumidify air)

If you have a small bathroom, the combination of a space heater on high and a strong fan can dry clothes in just a bit more time than a conventional clothes dryer takes.

I have a similar washer in my apartment and I have a question.... it may seem silly. Do I have to turn off my water when the machine is done filling and then turn it back on when it's time to rinse? For some reason I have this fear that the water will back up into the pipe and then my pipes will explode so I'm constantly turning on and off the water. Thank you.

Hi Bonnie! Great question! Water damage is SUCH a big deal, it makes sense to worry about it! Of course, the best advice is to check your washer's manual, which you should do, but as long as your washer has a valve on the inlet and is shutting off water when the washer is full (you'll be able to see/hear this during the cycle if the water stops flowing even when the hose connected to the washer is open to water flow) it's fine.

Your pipes are designed to hold back water pressure, and a hose connected to a portable washer doesn't put any extra pressure on the pipes in your home. The valve on the washer that blocks flow when the washer is full is, functionally, the same as what happens to the pipe in your sink when you turn off the faucet: water is blocked, and sits behind the blockage waiting to be turned on. Good luck and thanks for the question!

So glad I found your message. I am hoping you can give me some help. I live on SS and now in a three story building with laundry room on first floor and use a walker. I finally got a Super Deal portable washer that I like but it has a gravity drain hose and drains well until after about three loads it has water standing under the spinner. Can you tell me how tall a stool I need to put the washer on so it will drain all of the water out ?? Thank You

Hi Gloria, I'm glad you found a washer that seems to work for you. I'm not sure I would put a portable washer up on a stool- they rumble so much on the spin cycle that it's sure to come crashing down. I'm afraid you'll need either a very stable pedestal (maybe someone local could build one for you?) or a washer model that pumps out water instead of gravity drains.

Do you disconnect the washing machine hose every time you want to use it for shower or washing? Or basically you disconnect and re connect every time? Thanks


Wednesday 23rd of September 2020

Right, That's how I use it! If I needed to do multiple loads in a week I might use something like an on/off switch splitter to keep both the showerhead and washer hooked up, so I could turn a switch to redirect water rather than unscrew the unit from the water source, but just for doing a few loads on the weekends, it works great for me to be able to disconnect and roll the washer into a closet when I'm not using it.

Thank you so much for this post. I've wanted to purchase this machine for the longest while, but it cannot work with any of the faucets in my unit. Had not thought of using the shower hose. A game changer indeed!
