If your bathroom is the only place in your home with a working tap and a drain, a compact washer that fits beside the toilet is the practical answer — and the ones worth buying are twin-tub designs you fill by hand and drain into the tub or shower. This guide covers nine machines that genuinely fit a bathroom, sorted by what they actually do well: how much they hold, how dry the spinner leaves your clothes, and how much babysitting each cycle demands.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Above all, these are semi-automatic machines: you add the water yourself and move wet clothes between two tubs, so the real question is whether that routine fits your week. Below you’ll find a full breakdown of the best bathroom washing machine options for tight spaces.
Our Picks at a Glance
How To Choose The Best Bathroom Washing Machine
A bathroom washer only works if three things line up: it fits the floor space, you can reach a tap to fill it, and the drain hose can actually reach somewhere lower than the machine. Get those three right and the rest is preference. Get one wrong and the machine becomes a very heavy laundry basket.
Measure the floor first, then the door swing
These machines are wider than they look. A twin-tub unit runs roughly 21 to 27 inches across, which is often the full width between a toilet and a wall. Measure the gap before anything else, and check that you can still open the bathroom door past it. The tubs fill from the top, so you also want clearance above the lids to pour water in.
Match capacity to your weekly pile
Capacity is quoted as a total figure that combines both tubs, so a “25 lbs” machine is not washing 25 pounds at once. Look for the split — something like 14.3 lbs wash and 11 lbs spin — and treat the smaller spin number as your real limit per batch. As a rough guide, a full-size machine handles a week of clothes for two people in one go; these handle a few days.
Plan the fill and drain before you buy
Almost every model here is semi-automatic, which means you fill the tub yourself with a hose or a showerhead. A short fill hose is the single most common complaint in the reviews, so budget for a longer hose and a faucet adapter. On the drain side, most units rely on gravity, so the hose outlet must sit below the machine — a shower tray or a low tub works; a raised bathroom sink often does not.

In‑Depth Reviews
1. Greenvelly Portable Washing Machine, 25lbs Twin Tub Washer and Spinner Combo
Our pick — over 4★ from 80+ verified ratings; the strongest balance of quality and price.
Two tubs, three knobs, and 25 pounds of laundry capacity that fits against a bathroom wall.
This is the pick for anyone who does real laundry in a small bathroom — towels, underwear, and daily wear — and wants the washing and spinning to happen side by side instead of one after the other. The numbers behind that: 14.3 lbs of wash capacity driven by a 300W motor, plus an 11 lbs spin tub running a separate 250W motor. Those two motors can run at the same time, so one load spins while the next one washes. That overlap is the whole reason a twin tub beats a single-tub machine in a bathroom, where floor space is the scarcest thing you own.
Almost everyone who owns one says it cleans better than they expected — owners repeatedly say the cleaning result surprised them. One owner runs car towels, outdoor rags, and shoes through theirs in the garage and rates it above their indoor machine for heavily soiled items. Another sums the appeal up simply: “Works great and is easy to drain. Is great for underwear and delicate clothes.” The 3-knob layout helps here, because you set wash time anywhere from 3 to 15 minutes and spin time from 0 to 5 minutes, with Gentle, Normal, and Drain modes standing in for the fabric presets a full-size machine would give you.
The catch is that semi-automatic really does mean manual. You fill it by hand, you switch the knobs between wash and spin yourself, and you stay nearby while it runs. Owners are upfront that a leak can show up, and the fill hose and power cord are on the short side for a large bathroom with the tap far from the machine. Treat the hoses as the first upgrade and the machine itself holds up its end.
What this machine gets right
- 14.3 lbs wash and 11 lbs spin running at the same time — a faster turnaround than single-tub rivals
- Heavily soiled garage rags and shoes come out cleaner than an indoor washer manages
- 3 to 15 minutes of wash time and 0 to 5 minutes of spin, with Gentle, Normal and Drain modes for delicates
What you live with
- Manual water filling and manual switching between cycles — you cannot walk away
- Fill hose and power cord run short, so check your tap distance before buying
- An occasional unit arrives with a leak at the hose connection
Buy this if: your bathroom has a tap within a short hose run of the machine and you want wash and spin happening at once.
Think twice if: your tap is across the room, because the supplied hose will not reach and you will be filling from a bucket.
2. Superday Portable Washing Machine, 25.3lbs Mini Washing Machine and Spin Dryer Combo
The shower-stall favourite: it slips into a tub, hooks to the shower, and drains right where you stand.
Superday’s twin tub splits 25.3 lbs into a 14.3 lbs wash side and an 11 lbs spin side — the same working capacity as the Greenvelly above, but with a water inlet system that releases silver ions during the cycle, which the maker says helps reach deep into fabric fibres. Practically, that means you can drop it straight into the shower tray, fill from the showerhead, and let it drain into the same tray without ever carrying a full tub of water across the bathroom. It is the setup that shows up most in owner write-ups, and for good reason.
Control is genuinely flexible: five wash times from 0 to 15 minutes, five spin times from 0 to 5 minutes, and Gentle, Normal, and Drain wash modes, each tub running on its own timer. Buyers report the spinner leaves dri-fit fabric around 90% dry and everything else damp but ready to hang overnight. A recurring note is that the fill hose is a touch short for a shower hookup, and the kitchen-sink drain often will not fit — a bucket under the drain hose solves it in seconds. The honest sizing read, in an owner’s own words: “Small capacity: 7-8 shirts or 2 pants + 3-4 shirts.”
One thing nobody warns you about until you own it: the spin tub does not finish the job completely — the maker itself says to air-dry for 1 to 3 hours afterward — and lint can transfer onto dark clothes, so washing delicates inside out helps. Neither is a defect; both are the trade-off of a machine that squeezes into a shower.
Why it leads on trust: It is the most widely owned twin tub in this lineup, and owners mention cutting laundromat trips entirely rather than just reducing them. Setup takes a little trial and error with hose adapters, then it settles into a routine.
Reach for it if: your bathroom is a shower stall and you want the machine to live inside the tray.
Look elsewhere if: you expect bone-dry clothes straight out of the spinner — plan on a drying rack either way.
3. ROVSUN 11LBS Portable Washing Machine, Electric Washer and Dryer Combo
Half the laundry capacity of the big twin tubs, in roughly 22 pounds of machine you can lift alone.
If the gap between your toilet and your wall is barely two feet wide, this is the one that squeezes in. It splits 11 lbs total into a 7 lbs washer and a 4 lbs spinner, and it measures 14″D x 21.6″W x 23.6″H — noticeably shallower front-to-back than the Greenvelly at 13.38″D x 22″W x 25.2″H, though the two land within a whisker of each other in overall bulk. The depth is what buys you clearance past a door swing.
What buyers rate highest is how well the small machine performs, not how big it is — effectiveness and wash-dry speed are the two things owners keep coming back to. A 1300 rpm spin motor is the reason: clothes come out nearly dry after two to three minutes in the spinner, and owners running four loads inside an hour say the machine barely shakes as long as you do not overload it. The stainless steel drum and plastic body mean rust is not a worry, and at around 22 pounds total it is easy to shift from the bathroom to a closet when guests arrive.
The shortfall is capacity and drainage, and both are worth being honest about. Some units also spill water from the side while draining, which is the kind of thing a shallow tub or shower floor absorbs without drama. Put it on a flat, level surface and it behaves.
The bathroom-specific win: at 23.6 inches tall and 14 inches deep it fits under a counter lip or beside a pedestal sink where the wider twin tubs simply will not go.
Best for: studio bathrooms and single-person households where two or three shirts a day is the real workload.
Not for: families — the 7 lbs wash side fills fast and you will be running it constantly.
4. Bonusall 25.3Lbs Portable Washing Machine, Compact Single Tub Washer with Spin Dryer
One tub, one timer, and a load rating that quietly beats the twin-tub machines in the wash department.
Here is the oddity worth knowing: this single-tub machine is rated for 16 lbs of laundry in one drum, while the 25 lbs twin tubs above only wash 14.3 lbs at a time. That is because their total is split across two tubs, whereas this one puts everything into the wash. So on a pure per-cycle basis, you load more socks, underwear, and baby clothes here than into either twin tub — you just lose the ability to spin a second load while the first washes.
Owners lean on it for exactly that: socks, underwear, delicates, and kids’ clothes that would otherwise pile up for a laundromat run. The timer is dead simple — up to 15 minutes for washing, 5 minutes for spinning — with a push-button control panel and an end-of-cycle signal so you know when to come back. A built-in handle and a light body make it easy to lift onto a bathroom shelf or into a closet between washes. One owner running theirs for three months describes it as 3 ft tall and powerful, with the spin-dry cycle leaving clothes dry enough to hang in about an hour.
Two things to weigh. First, this is a washer with a spin cycle rather than a separate dryer tub, so every batch is wash, drain, spin, repeat — no overlap. Second, durability is the recurring gripe among long-term owners, with several reporting failures after seven months and one wishing their previous brand had simply been repaired instead. Treat a low-cost machine like this as a replaceable appliance rather than a ten-year buy and it does its job well.
Where it earns its place
- 16 lbs wash rating loads more per cycle than the 14.3 lbs twin tubs
- Push-button timer with an end-of-cycle signal — no knob-twiddling mid-wash
- Built-in handle and a light body make it easy to store between uses
Before you commit
- Single tub means no washing and spinning at the same time
- Long-term durability is the weakest point customers note
- Size splits opinion — some find it smaller in person than expected
Choose it when: your laundry pile is light and daily, and you want one simple drum with a signal when it is done.
Skip it when: you want a machine that lasts a decade — this is a replaceable appliance, not an heirloom.
5. Pataku Portable Washing Machine, 25.3 Lbs Compact Mini Washer and Dryer Combo
A pre-soak setting that gives stained work shirts a head start before the wash even begins.
Most machines in this group give you a timer and leave it at that. Pataku adds a soaking function that runs 0 to 20 minutes before the wash cycle, which is the one feature that actually changes results on grass stains, food spills, and anything a kid has been wearing all day. The rest of the spec sheet is familiar twin-tub territory: 25.3 lbs total split into a 14.3 lbs wash tub and an 11 lbs spin tub, a 15-minute wash timer, a 5-minute spin timer, and a stainless steel drum inside a PPC body with a glass cover.
The people happiest with it are the ones who have built it into a routine rather than plugged it in and expected magic. The standard playbook across owner reviews: stand it in the shower, fill from the showerhead, use less detergent than you would in a full-size machine, rinse, then spin a third to half a load at a time so the drum can actually move the clothes. Done that way, the spin pulls out almost all the water and clothes come out close enough to dry that hanging finishes the job. One quirk worth adopting: switch the knobs to the drain position after draining to stop drips.
Where it frustrates people is the plumbing, not the washing. The drain hose is widely reported as too short to reach a sink or tub, so plan on draining into a bucket or buying an extension. The inlet hose is all plastic with no faucet adapter, which means holding it in place while the tub fills unless you add one. Buy the two adapters alongside the machine and the experience changes completely.
A word on expectations: this machine cleans well, but it is not a machine you set and forget. Budget for a drain extension and a faucet adapter, and it punches well above its footprint.
Ideal for: anyone whose laundry problem is stains rather than volume — the 0 to 20 minute soak does the heavy lifting.
Less ideal for: hands-off households, since the short hoses mean you will be standing there for the fill and the drain.
6. COSTWAY Portable Washing Machine, Twin Tub 26lbs Capacity with Built-in Drain Pump
The one that solves the drain problem outright — 18 lbs of washing with a pump that pushes water uphill.
Every other machine in this guide relies on gravity to empty itself, which means the hose outlet has to sit lower than the tub. COSTWAY builds a drain pump into the unit so you can send the wastewater to a higher spot or wherever is convenient. In a bathroom where the only drain is a shallow sink or a shower tray with a lip, that single feature decides whether the machine is usable at all. On top of that it runs the biggest wash batch here: 18 lbs in the laundry tub against 8 lbs in the spin tub, for 26 lbs total.
The motor setup explains why it handles that volume: 280W of washing power and 140W of spin power, with wash time settable from 0 to 15 minutes and spin time from 0 to 5 minutes. It also runs quietly enough not to carry through apartment walls, and the transparent lid lets you watch the cycle without lifting anything. Owners clearing several days of clothes at a time from a small apartment consistently say the compact footprint and the fast spin make it worth the counter space it eats.
Be straight about two things. The machine gets clothes to roughly 90% dry rather than fully dry — the maker says so plainly and tells you to hang them in the sun to finish. And the drain hose is the flimsiest part of the package, described by more than one owner as thin and easy to crumple. A replacement hose is inexpensive; just know it is coming. A small number of units have had the agitator seize, so keep your receipt and test it properly in the first week.
Reasons it stands out
- Built-in drain pump means no gravity requirement — drain uphill if your bathroom demands it
- 18 lbs wash tub is the largest single wash batch in this lineup
- 280W wash and 140W spin motors, with a transparent lid for checking progress
Reasons to pause
- Gets laundry to about 90% dry, not fully dry — drying still happens on a rack
- The supplied drain hose is thin and crumples easily
- A few units have arrived with a seized agitator, so test yours in week one
The right call if: your bathroom drain sits level with or above the machine and you refuse to improve it on blocks.
Wrong call if: every inch of floor space is spoken for — at 27.5 inches wide it needs a real footprint.
7. Giantex Portable Washing Machine, 20lbs Twin Tub, 12lbs Wash and 8lbs Spin
The stall-shower workhorse with a three-year ownership trail and a spinner that behaves like a jet engine.
Giantex splits 20 lbs into a 12 lbs wash tub driven by a 300W motor and an 8 lbs spinner on a 110W motor, with a filter net in the wash barrel to catch lint and a cover plate that keeps clothes from flying out of the spin tub. It measures 14″D x 25″W x 29″H, so it will slip into a stall shower with room to spare. What really separates it is the length of the ownership record: buyers describe running it for three years through small loads of two jeans, a few towels, or sheets, with the spinner draining continuously rather than pooling water underneath.
The cycle technique owners converge on is worth copying. Load a small batch so the clothes have room to move, use far less detergent than you would in a full-size machine, add fabric softener to stop stiffness, then wash, drain, rinse, and spin in separate passes — six minutes of wash and six of rinse is typical, with the spin run in two batches. Several owners say it cleans better than the shared building laundry. The spinner genuinely performs too; owners describe clothes coming out around 90% dry and hanging dry in about an hour even in high humidity.
Two recurring quirks to plan around. The spinner drain can clog if lint builds up — clearing the flap valve beneath the tub and raising the unit for clearance fixes it. And the printed manual reads like a rough translation, so most of the useful guidance comes from other owners rather than the paperwork.
What owners praise most
- Reviewers point out three years of small daily loads without a failure
- The 110W spinner leaves laundry around 90% dry and drains continuously
- Lint filter net and a spin cover plate handle the messy parts for you
What to expect
- The spinner drain can clog and needs occasional clearing
- Instructions are poorly translated, so the learning curve comes from owners online
- It uses a generous amount of water per wash
Worth owning if: you want a machine with a long, proven track record and you are happy to run small, frequent loads.
Think it over if: you want to fill one big drum and walk off — the 12 lbs wash side rewards patience, not bulk.
8. Giantex Portable Washing Machine, 20lbs Capacity Twin Tub, Blue and White
A no-hookups twin tub that plugs into a standard wall outlet and just gets on with it.
This is the same 12 lbs wash and 8 lbs spin split as the Giantex above, with a 300W washing motor and a 110W spinner, packaged in blue and white and built for people who rent and cannot touch the plumbing. It runs off a normal outlet, needs no installation, and the wash timer goes to 15 minutes while the spin runs 5 minutes per load. The wash barrel carries a filter net you can pull off for cleaning, and there is a cover plate to keep laundry from being thrown out at speed during the spin.
What buyers notice first is how much machine you get for a compact unit. Owners describe it as sturdy rather than flimsy, plugging into a standard outlet with no wheels but light enough to reposition. The wash side takes a decent load and cleans it in minutes; the spin side is smaller and has no heat, so clothes come out slightly damp and need two spin batches per wash. That is normal for this class of machine — there is no drying element in any of them, just a fast spinner removing water. One owner two months in runs the whole thing from a bathroom stand with risers for gravity drainage, filling from the showerhead, and rates it as exactly what a renter without hookups needs. Another put it well: this machine earns its keep when you live somewhere without a washer and dryer connection, because it washes clean and spins clothes out for fast hang drying.
One honest caveat on quality control: a rare unit arrives damaged, and because this model has been sold for years the listings mix fresh stock with older inventory. Check the tank on arrival before you fill it for the first time.
The renter’s calculus: Two loads a week replace a laundromat run, and one owner is 18 months into exactly that schedule.
Pick it when: you have no laundry hookup, a standard outlet, and a showerhead you can reach with a hose.
Skip it when: you want heat drying — the spinner removes water, nothing more.
9. Auertech Portable Washing Machine, 20lbs Twin Tub with Drain Pump
A drain pump and an adjustable inlet hose, for bathrooms where gravity will not cooperate.
Auertech takes the same 12 lbs wash and 8 lbs spin layout as the Giantex models but adds a drainage pump and an adjustable inlet hose, so you can push wastewater to a higher position or just somewhere convenient. If your only bathroom drain is a pedestal sink or a shower tray with a raised lip, that combination is what makes the machine workable. The 1300 rpm motor does the cleaning, the tubs are translucent so you can watch progress, and the compact body is built to tuck into a bathroom corner or a closet between uses.
Three control switches handle wash time, wash mode, and spin time, and there are two water inlets on the panel for connecting the fill hose. Owners tend to describe the setup as straightforward once they have learned it — fill, set the timers, drain — and the recurring praise is about results rather than features: clothes come out clean, the spinner gets them close to dry, and a retractable clothesline finishes the job while taking up almost no space. Apartment tenants who used to queue at a shared laundry report their monthly laundry spending drops once this machine is in the bathroom.
Two practical warnings from steady users. First, there is no auto shutoff on the fill, so you have to watch the water level or risk a flood — a minor thing until the day you forget. Second, do not overload the spin tub or it will leak; one sheet at a time is the safe pattern for bedding. Noise and durability draw a mix of reactions, with most units holding up fine and a few failing early, so the usual advice applies: test it thoroughly in the first week while the return window is open.
The case for this one
- Drain pump plus adjustable inlet hose remove the gravity constraint entirely
- 1300 rpm motor cleans well, and the spinner leaves clothes nearly dry
- Three switches cover wash time, wash mode, and spin time without menus
Where it asks for care
- No automatic shutoff on filling, so you must stay close while it runs
- Overloading the spinner tub causes leaks — one sheet at a time
- Durability is inconsistent, so verify the unit works fully on arrival
Made for: a bathroom where the drain sits high and no amount of gravity will help.
Not made for: anyone who wants to start a fill and walk away — you have to watch the water line.
Understanding the Specs
Wash Capacity vs Spin Capacity
Manufacturers quote a total figure that adds both tubs together, so a 25 lbs machine is not washing 25 pounds of dry clothes at once. The number that matters is the wash rating — usually 7 to 18 lbs here. Spin capacity runs smaller because wet clothes are heavier and the spinner needs room to throw water out, so a machine rated 14.3 lbs wash and 11 lbs spin will take a full wash tub but only part of one in the spin side.
What Semi-Automatic Means
Every machine here is semi-automatic, which means no water connection and no automatic program. You fill the tub with a hose or showerhead, add detergent, set a timer knob, then manually drain and move the clothes to the spin tub. Timers typically run 0 to 15 minutes for washing and 0 to 5 minutes for spinning. The upside is fewer parts to fail and no plumbing work; the downside is that a wash cycle is something you supervise rather than start and leave.

Final Thoughts: The Verdict
For most bathrooms, the bathroom washing machine that gets the balance right is the Greenvelly 25lbs Twin Tub — 14.3 lbs of wash capacity and an 11 lbs spinner that can run at the same time, three knobs instead of a menu of programs, and a track record of cleaning better than the indoor machines it replaces. If your bathroom is a shower stall, grab the Superday 25.3lbs, which is built to live inside the tray and filled from the showerhead. For a bathroom where the only drain sits high, the COSTWAY 26lbs and its built-in drain pump, or the Auertech 20lbs, remove the gravity headache entirely. And if space is so tight that 20 inches of clearance is a luxury, the ROVSUN 11LBS is the smallest of the group with a 1300 rpm spin.
