The potty training supplies checklist, no upsells

This is a plain list, not a shopping guide. Nothing here links to a product or recommends a brand, and everything on the essential list is genuinely low-cost and easy to find wherever you already shop.

What you actually need

Underwear, 8 to 10 pairs. This is the one item worth buying in real quantity, because you’ll go through most of it in the first couple of days of an intensive campaign. Let your child pick the prints or characters; the small ritual of choosing them does real work in building buy-in, and it costs nothing extra.

A potty chair, or a toilet reducer seat plus a step stool. Either works. A floor potty chair feels less intimidating to some toddlers because it’s their own size and doesn’t involve the toilet itself. A reducer seat that fits onto your existing toilet, paired with a stool so small feet aren’t dangling, skips a later transition since your child is already using the real toilet from day one. Pick based on what your child seems more comfortable with, not on any claimed advantage of one over the other.

A few full changes of clothes, staged around the house. Not just in the bedroom. If you’re running an intensive campaign, keep a complete change (top, bottom, underwear, socks) in every room you’ll actually spend time in, so a reset takes 30 seconds instead of a trip upstairs mid-accident.

Something to protect furniture and car seats. Old towels work fine. A cheap waterproof liner or a towel over the car seat during the campaign days saves you a much bigger cleanup later. This doesn’t need to be purpose-built potty training gear; anything washable and disposable-adjacent does the job.

A small bag for outings. Once you’re taking short trips (see the 3-day method guide for when that typically starts), a plastic bag or a simple wet bag for a soiled outfit means you’re not carrying it loose in the car.

What’s genuinely optional

A visual timer or a phone alarm, useful specifically for the scheduled-sits method, where a consistent interval matters more than for the intensive method. Any timer works; nothing about this needs to be marketed as a potty training product.

A sticker chart or simple progress tracker, only if your child responds well to visible progress. Plenty of children do fine, or even better, without one; it’s worth trying without first and adding it only if motivation seems to be flagging.

A couple of books about using the potty, helpful mainly during the prep week to normalize the idea before the campaign starts, and genuinely useful throughout the gradual, child-led method, where low-pressure exposure is the whole point.

A travel potty seat, worth considering once you’re a week or two past the initial campaign and starting to take longer outings, but not something you need on day one.

What you almost certainly don’t need

Branded “potty training kits” that bundle a handful of these items together at a markup rarely offer anything the individual pieces don’t. Reward toys or elaborate prize systems aren’t necessary for most children; praise and the small ritual of picking out underwear tend to carry most of the motivation on their own. And nighttime-specific training products are worth holding off on entirely, since nighttime dryness runs on its own physiological timeline separate from daytime training; see the nighttime guide for why pushing that earlier rarely helps.

How this fits into your plan

The day-by-day planner includes this same essential list in your prep-week checklist, dated against your actual start date, so you know exactly which day to have everything staged by.
