How to Do Laundry in an RV
Doing laundry in an RV is manageable with the right portable washer and a water-smart workflow. This guide covers machine selection, hookup, drainage, drying, and storage for life on the road.
The practical approach to doing laundry in an RV is a compact portable washer that connects to your kitchen or bathroom faucet with a simple adapter, runs a load while you make coffee, and drains into the sink when finished. No dedicated laundry hookups, no permanent plumbing, and no driving to a laundromat.
Space and water are the two constraints that shape every decision about RV laundry. A machine that sits on a counter when in use and slides into a cabinet when stored works for couples or solo travelers. A freestanding semi-automatic model with a larger drum is more practical for families but needs a designated spot. Water consumption matters whether you are on hookups or boondocking, so matching machine size to your actual load volume keeps gray water use under control. The sections below work through each piece of the decision.

Choosing the Right Machine for Your RV
The most important filter is physical size. Measure the spot where the washer will sit and the cabinet or compartment where it will be stored, and then buy a machine that fits both measurements with room for hoses. For one or two people, a countertop model like the Costway GT-23104-CYWH at a 5.5-pound capacity and a weight of 12.1 pounds is easy to move and fits in a standard cabinet. For a family of three or four, a freestanding semi-automatic washer like the Giantex EP21684 at a 20-pound capacity handles larger loads but needs a dedicated spot on the floor. Fully automatic units like the Hamilton Beach HBPW3O2AMZ at $448 are heavier and need a permanent position, but they cycle from wash through spin without manual intervention. Capacity and automation level both affect how much hands-on time laundry takes each week.
Connecting to Your RV Water Supply
Most portable washers connect to a standard faucet using the quick-connect adapter included in the box. On an RV with city water hookup, attach the adapter, turn on the faucet, and the machine fills normally. If you are on your freshwater tank, confirm the pump is running and the tank has enough water before starting a cycle. Twin-tub and semi-automatic models let you fill the wash basin manually with a pitcher or a short hose if the faucet distance is awkward. Check the connection point for drips before starting a full cycle. A small leak at the adapter fitting will drip water inside your RV for the entire wash time, which is not a good situation. A wrench-tight connection and a paper towel check at the start is worth 30 seconds.
Managing Water Use and Drainage
RV freshwater tanks typically hold 40 to 100 gallons, and a single wash cycle can use 5 to 15 gallons depending on the machine and settings. Running smaller, full loads uses water more efficiently than running multiple partial loads. For drainage, most portable washers have a pump that pushes water through a drain hose you position in the sink or shower drain. This gray water goes into your RV gray tank. A few campgrounds prohibit draining wash water onto the ground, so using the gray tank is the default safe option. Biodegradable detergent helps if you do need to manage gray water disposal at a dump station. For twin-tub models without a drain pump, gravity drain into a low bucket that you then carry to the dump point.
Drying Clothes Efficiently in a Small Space
Most portable washers for RVs do not include a drying function. The spin cycle extracts a meaningful amount of water, so clothes are damp rather than soaking wet when the cycle ends. A portable spin dryer like the Avalon Bay EcoSpin at $89.98 takes that further and cuts air-dry time considerably. From there, a retractable clothesline strung across the RV interior or a compact folding drying rack handles most garments. In humid weather, cracking windows and running a fan prevents clothes from staying damp for too long. Synthetic fabrics dry faster than cotton, which matters when you are drying inside a 30-foot space. If you have access to shore power at a campground, a compact vented dryer is also an option, though it adds weight and takes up space that may not exist.
Storing the Washer Between Uses
Countertop models at 12 to 15 pounds are easy to store in a kitchen cabinet or an under-bench compartment. The Costway GT-23104-CYWH fits comfortably in a standard cabinet when the hoses are disconnected and coiled. Larger freestanding units need a closet or a dedicated storage area, either inside the RV or in an exterior compartment if the weather is mild. Before storing any portable washer, disconnect the hoses, drain every bit of remaining water from the drum and the hose ends, and wipe the drum dry. Water left in hoses or the pump during freezing temperatures will expand and crack the housing. Even in moderate climates, a dry drum and dry hoses prevent mildew from forming during storage.
Common Problems and Simple Fixes
If the washer does not fill, the most common cause is the water pump not running, the freshwater tank being too low, or the faucet adapter not seated tightly. If the machine vibrates heavily during the spin cycle, the load is unbalanced. Stop the spin, redistribute the clothes more evenly, and restart. Semi-automatic models with a separate spin tub are especially sensitive to unbalanced loads, so do not stuff the spin tub to the rim. If the drain pump seems to be running but water is not draining, the drain hose may be too high above the machine. The hose should slope downward toward the drain without any sections that rise above the pump outlet. Most issues with portable washers on the road trace back to connection fit, load distribution, or hose positioning rather than mechanical failure.
Frequently asked questions
Can I use a regular washing machine in an RV?
Full-size washers are too heavy, too wide, and require dedicated 240-volt hookups that most RVs do not have. Compact portable washers designed for small spaces are the practical alternative. They run on standard 110-volt outlets and connect to your existing faucet.
How much water does an RV portable washer use?
Most compact portable washers use 5 to 15 gallons per load. Semi-automatic models use less because you control the fill level manually. Running full loads rather than partial ones keeps per-garment water use low.
Do I need a special detergent for RV laundry?
Use a high-efficiency (HE) detergent, preferably liquid, which dissolves fully in cool water and produces fewer suds. Biodegradable formulas help if you need to manage gray water at a dump station. Regular powder detergent can leave residue in lower water volumes.
How do I dry clothes without a dryer in an RV?
Run the washer's spin cycle to remove as much water as possible, then hang clothes on a retractable clothesline or foldable rack. A portable spin dryer like the Avalon Bay EcoSpin at $89.98 takes more water out before hanging, cutting dry time significantly in humid weather.
