When we were planning the interior layout for our latest build, the laundry question came up early: do you sacrifice kitchen storage space for a washing machine, or do you live with laundromat runs? For most people doing this full-time, the laundromat answer stops being acceptable within a few months. The question becomes which type of machine actually works in the space you have.
In a tiny home, there's almost never room for separate washer and dryer units. That leaves you with the all-in-one washer-dryer combo category — a single drum that washes and then dries in sequence. These machines have a reputation for slow dry cycles and vibration that shakes the whole trailer. That reputation is partly deserved and partly outdated. Here's an honest comparison of the three main options.
1. The Stationary Option: LG All-in-One (Ventless)
The LG ventless combo is the closest thing to a conventional laundry experience available in a tiny home. It uses condensation drying — it heats the air inside the drum, pulls moisture from the clothes, condenses that moisture back into water, and drains it through the same outlet as the wash cycle. No vent hole required in the wall, which in a well-insulated build is a significant advantage. A 4-inch hole through insulated siding is a thermal weak point and a water ingress risk if not sealed properly — eliminating the need for it entirely is worth something.
The honest limitation is cycle time: a full wash-and-dry run takes 3 to 4 hours. That's not a dealbreaker — it's a habit change. Put a load in before you leave in the morning, and it's done when you get back. For full-time residents on a routine, this works well. For anyone who needs clean clothes in an hour, it doesn't.
2. The Mobile Option: Splendide Vented Combo
The Splendide is the machine RV owners have been running down highways for years — it's engineered specifically for mobile use, with vibration damping and build quality designed to handle transport. The vented approach exhausts hot air directly outside, which dries clothes significantly faster than condensation drying: typically 1.5 to 2 hours for a full cycle rather than 3 to 4.
The trade-off is the 4-inch vent hole. In a THOW or RV build where the hole is planned during construction and properly flashed and sealed, this is manageable. In a finished build where you're retrofitting, cutting through finished siding and insulation is more involved. It also represents a permanent penetration in the thermal envelope — minor in mild climates, more meaningful in cold ones.
3. The Off-Grid Option: Portable Twin-Tub Washer
For setups without plumbing connections or with very limited power, the twin-tub portable is the practical answer. It sits in the shower pan during use, connects to the shower hose for fill, and drains into the same drain. When you're done, it stores in a closet. Power draw is minimal, water usage is very low, and there's no installation required.
The limitation is drying: the spin cycle removes most of the water but not all of it. Clothes come out significantly drier than hand-wrung but still need to air-dry for an hour or two. A retractable line in the shower or a small portable dryer handles the rest. For boondocking and off-grid situations where the alternatives require infrastructure that isn't there, this is the realistic choice.
Head-to-Head: Tiny Laundry Specs
| Feature | LG All-in-One | Splendide Vented | Portable Twin-Tub |
|---|---|---|---|
| Venting | Ventless (Condensing) | Vented (Needs Hole) | None (Hang Dry) |
| Cycle Time | 3–4 Hours | 1.5–2 Hours | 20 Mins (Wash only) |
| Water Usage | Moderate (12–15 gal) | High (15+ gal) | Very Low (Manual) |
| Best For | Parked Tiny Homes | Heavy Duty / Mobile | Off-Grid / Budget |
For most stationary tiny home builds, ventless wins. No vent hole, no thermal envelope compromise, and a long cycle time that works fine once you build it into your routine.
