8 Best Dog Potty for Balcony | Skip the Elevator, Your Dog Will

A roll of real-feel grass you cut to your exact balcony shape.

This is not a tray system — it is a 4-foot by 6-foot sheet of UV-resistant, polyethylene grass that you trim with scissors to fit any balcony, crate, or deck. The grass stands 1.38 inches tall, which is tall enough to look convincing but short enough that urine does not get trapped at the base. The highly-drainable backing and porous structure mean liquid passes through almost immediately, so paws stay dry. Owners mention that dogs take to it quickly: “My puppy used it immediately” is a common refrain, and in extreme Arizona heat it “hasn’t blown away or melted.” The catch is that without a solid tray underneath, you need a separate drip pan or a layer of charcoal puppy pads to keep the concrete below from absorbing smell. On a balcony that already has a slight slope for drainage, this works beautifully rolled out on its own. The crowd favorite — 4.4 stars across 600+ owners — shows that the texture and realism overcome the extra setup step. And at 24 square feet, you can cut it into two smaller pads and rotate them while one dries after hosing.

The tray that does not absorb yesterday’s smell.

Plastic trays can yellow and hold onto odors after a few months in the sun. This one uses a stainless steel base that resists chewing, scratching, and — most importantly — odor absorption. The 28-by-20-inch system is a three-layer build: the upgraded 4-layer woven grass mat sits on top of a washable pee pad, which drops into the steel tray. Customers note that a 10-pound dog used it on an apartment deck through a whole winter, with the owner swapping disposable pads under the grass and soaking the grass in bleach water weekly. After a full year, both the grass pads (two are included) still held up. The drying time gets specific praise: the grass dries fast enough that a pressure hose leaves it ready for reuse in minutes. The size gets mixed feedback — some find 28 by 20 inches perfect for a 16-pound pug, others call it too large for a small balcony. On a mid-size balcony, though, this is the most hygienic option because the steel tray does not hold bacteria the way plastic can.

A tiny tray for tiny dogs that fits on a postage-stamp balcony.

At 23.6 by 15.5 inches, this is the smallest complete potty system here — and the most size-specific. The brand tells you exactly which dog fits: any dog whose length from nose to base of tail is under 19 inches. That covers Yorkies, Chihuahuas, and toy breeds. The upgraded pad uses a knitted and melted bottom that lets urine flow straight into the plastic tray below, which cuts down on stink noticeably. Owners rave about the quality (it is the top praise, mentioned most often by a wide margin) and the ease of cleaning — the grass pads are machine washable and come hemmed so they do not unravel in the wash. In fact, the hemmed edge is a standout detail because it prevents the shredding that cheaper pads suffer after a few cycles. The two included grass mats mean you can swap them while one is drying. The catch: the tray itself is flimsy — it is the most common durability gripe. That matters less on a balcony floor than it would on a lawn, but handle it gently when you lift it to dump the tray. Overall, the crowd feel (4.3 stars across 600+ ratings) is that this is a perfect size for a small-breed dog in an apartment or condo where space is at a premium.

A surprisingly large grass mat for the price, but bring your own backup pad.

At 32 by 24 inches, this mat offers a decent footprint without costing much — it is the most affordable full-size grass-plus-pad kit on the list. The TPU-backed grass has a sturdy buckle that fastens the reusable pad underneath, keeping everything aligned. Owners love the texture; dogs take to it quickly, and the mat is soft enough that at least one owner found their puppy using it as a scratching pad instead of a potty (which says something about the realistic feel). The dense, thick construction drains fast, and the grass plus the pad together are machine washable. The recurring gripe is water resistance — as some owners put it: “Dogs used them, but we had to put piddle pads under them, which kind of defeated the point.” That means the included pad is not fully waterproof on its own. On a balcony, this is easy to solve by placing a plastic tray or a garage drip pan underneath, but it is an extra step you do not have with the pricier all-in-one systems. For the price, it is a solid entry option for puppy training or for a second station on a covered balcony.

Grass that refuses to shed, even when a Shih Tzu scratches the daylights out of it.

The ELLOTY system uses a support panel and a non-slip base to keep the whole unit planted on the balcony floor, which is helpful if your balcony is tiled or smooth. It includes a washable waterproof pee pad underneath the grass so nothing soaks through to the concrete. At 4 pounds, it is light enough to carry in from the balcony before a storm, but heavy enough that a gust of wind will not flip it. Reviewers point out that the grass “doesn’t shed” even after repeated scratching — the construction is tight enough to hold the blades without shedding. The odor resistance is strong enough that one owner keeps it on their lanai and hoses it down every other day with Simple Green, replacing the grass pad every few months. The two main caveats: some dogs refuse to use it (a couple of Chihuahua owners had no luck), and the brand recommends good ventilation if you use it indoors. On an open balcony, that last note is irrelevant. The reliability and build quality get top marks from owners, making this a safe pick for a covered porch or small balcony.

A take-anywhere potty that packs flat for road trips.

This system adds a middle layer you will not see on most competition: a 1.5 cm high-density pearl cotton pad between the grass and the tray. That cotton pad acts like a sponge, pulling urine out of the grass and holding it in the middle so the dog’s paws stay dry. The tray has raised edges to catch drips, and the whole thing measures 23.6 by 17.3 inches — small enough to toss in an RV or pack for a hotel stay. Ease of cleaning comes up as the top positive by a massive margin, with owners specifically calling out how easy it is to rinse the three parts separately and let them dry. The grass is a realistic green, soft underfoot, and the included pearl cotton pad does not deform after multiple washes. Durability gets mixed feedback — some shoppers say the grass fraying along the edges after a few months. On a balcony, that fraying is cosmetic rather than functional, but it is note if you want a system that looks pristine for years. For a small dog (3 to 10 pounds) on a small balcony, this is a nimble, lightweight solution.

A featherlight grass mat for a tight budget — but plan to replace it every season.

At 0.53 kilograms (just over a pound), this is the lightest option on the list. The 33.2-by-20.8-inch mat has drainage holes throughout that the brand says deliver 2X faster drainage than standard pads. The polypropylene and TPU material is weather-resistant, so it handles sun and rain on a balcony without melting or rotting. The texture divides opinion sharply: some owners love the soft, realistic feel, while others call it “harsh, prickly texture like artificial Christmas tree” and say it is too rough for a small dog’s paw pads. The reality is that this is a budget-priced mat that you buy knowing it will need replacing — as owners note, you should expect to “replace every 3-6 months due to fabric breakdown and grass loss” — and the edges are not sewn, so they unravel if you hand wash them. For a balcony used occasionally or as a backup station during bad weather, the low upfront cost makes sense. Just pair it with a plastic tray or a cheap oil pan from an auto shop underneath to catch the runoff, since it has no built-in tray. The manufacturer backs it with a 1-year warranty and lifetime customer service, which adds confidence at this price tier.
