My neighbor two floors down has a whippet and a fourth-floor walkup with no elevator. At 11pm in January, that combination gets old fast, which is exactly why she switched to an indoor setup last winter and hasn’t looked back. If you’ve searched anything about indoor potty options, you already know the marketing makes them all sound interchangeable. They’re not. Grass pads, fake turf, plumbed porch potties, and plain pee pads solve different problems, and picking the wrong one for your building means a dog who still won’t use it, or a smell you can’t get rid of by March.
This is a comparison of what each type actually does well, where it falls apart, and which one fits your specific apartment, not a generic “here are five products” list. If you’re just starting potty training from scratch, our apartment puppy potty training guide covers the schedule and method side of things; this article is about the hardware.
Real grass pads (sod trays)
These are trays of actual grass grown on a thin soil pad, usually delivered every one to two weeks by a subscription service. Dogs take to them fastest of any option because the scent and texture match what they’d choose outside anyway. That’s the whole selling point.

The catch is upkeep. A tray lasts a dog roughly a week to ten days before it’s saturated and starting to smell like a wet lawn left too long in a bag, which, functionally, it is. You’re also paying a recurring fee, usually somewhere in the 25 to 45 dollar a month range depending on tray size and delivery frequency, and you need a spot to store the old tray until pickup. For a studio, that’s a real space cost. We rank a batch of these in our grass pads for apartments roundup if you want brand-specific picks; a couple of those services deliver to most major US metros.
Is real grass better than fake turf for dogs?
For getting a dog to actually use an indoor spot, yes, usually. Fake turf needs more encouragement early on because the plastic texture reads differently to a dog’s nose and paws. But real grass loses on almost everything else: cost, mess, and the fact that a tray of decomposing sod is not something most people want next to their kitchen.
Artificial turf mats
Fake grass on a drainage tray, usually a two or three layer system where liquid passes through the turf into a tray underneath. You rinse the turf and empty the tray instead of replacing anything. This is the option most people land on after a few months of trial and error, because the ongoing cost is close to zero once you own the mat.
Two things matter here that most buying guides skip. First, drainage holes clog with hair and debris faster than you’d think, so a mat that seemed fine in month one can start pooling liquid on top by month four if you’re not rinsing it thoroughly. Second, size matters more than brand: a medium dog needs at least a 20 by 25 inch mat to actually aim onto it reliably, and a lot of the cheap ones sold online are closer to cat-litter-box size. Check dimensions before you buy a artificial grass potty tray, not just the photo.
Plumbed porch potties
These connect to your home’s plumbing so liquid drains automatically instead of collecting in a tray, using a garden hose attachment or a direct line if you’re handy. It’s the closest thing to a self-cleaning system on this list, and if you own your unit or have a landlord who’ll allow the install, it removes almost all the daily maintenance.
For renters, this is usually a non-starter. Most leases won’t let you run a permanent plumbing connection, and even where they would, it’s a project, not a weekend fix. If you’ve got a balcony with an outdoor spigot nearby, a plumbed porch potty system is worth a look; for the average rental apartment, skip straight to turf or pads.
Pee pads
Absorbent disposable pads, the cheapest and simplest option to start with, and honestly the right choice for very small dogs, seniors with mobility issues, or anyone who needs a backup during a stretch of bad weather rather than a full-time solution. A large dog will soak through a standard pad and track it across the floor, so if you’re going this route with anything over 25 pounds, buy the extra-large pads, not the regular size, and expect to use two at once during the training phase.
The downside is obvious once you’ve used them for a month: the trash bill adds up, and pads that shift out of a holder tray get shredded by bored puppies more often than any other option on this list. A pad holder tray with raised edges solves most of that.
Which indoor potty option works best for small apartments?
If cost and hands-off convenience matter most, turf wins. If you want the fastest training with money not being a factor, real grass wins early on. If you’re renting and can’t commit to either, pee pads in a holder tray are the safe default until you know your dog’s habits well enough to upgrade. A lot of owners actually run two systems in parallel for the first month: pads by the door for backup, turf or grass as the primary target, then drop the pads once the dog is reliably using the main spot.
What nobody tells you about the switch to outdoor walks
An indoor system isn’t meant to replace walks forever for most dogs, and if you’re using one because of a broken elevator, a rough winter, or a very young puppy who isn’t fully vaccinated yet, that’s a temporary bridge, not a permanent lifestyle. Dogs that get too comfortable with an indoor-only routine can become reluctant to go outside at all, especially small breeds that never developed the habit. If your building’s layout makes outdoor trips a genuine hassle long-term, our apartment dog breeds scorecard is worth checking before your next dog, since some breeds handle low-exercise, mostly-indoor living far better than others.
Whatever you land on, give it three full weeks before deciding it “doesn’t work.” Most of the complaints I hear about indoor potty gear turn out to be a training timeline problem, not a product problem. The dog needs to learn the new spot has the same rules as the old one, and that takes longer than the box promises.
Frequently asked questions
What actually removes dog urine smell?
An enzymatic cleaner. It breaks down the uric acid crystals that ordinary cleaners leave behind, which is exactly why the smell keeps coming back without one.
Why does my house still smell like dog pee after cleaning?
Regular cleaners mask it but leave the uric salts in the carpet pad or subfloor. Humidity reactivates the odor until an enzyme cleaner digests it.
Does vinegar get rid of dog urine?
It helps with fresh, light accidents and neutralizes some odor, but it will not break down set-in stains the way an enzyme cleaner does.
