Potty training, in product terms, is one of those phases the baby aisle does an excellent job of overcomplicating. UK parents end up with branded toilet-training stickers, multiple novelty potties, training underpants in five colours, and "rewards" charts costing £15, when most of the actual work needs maybe £40 of basic kit and a lot of clean trousers.
Honest summary: the products are easy. The training is the hard part, and no product makes it faster.
What you actually need
For a typical toddler (18-30 months) starting potty training:
| Item | Notes | UK cost |
|---|---|---|
| 2 basic potties | One for upstairs, one for downstairs. Cheap. | £8-£15 each |
| Toilet seat reducer | Once they graduate from potty | £10-£20 |
| Step stool | Hand washing, toilet access | £15-£30 |
| Pull-ups (for nights/outings) | Pampers, Huggies, supermarket own-brand | £8-£15/pack |
| Cotton training pants | For daytime; absorb small accidents | £15-£25 for 5-pack |
| Waterproof mattress protector | Going to need one | £15-£40 |
| Waterproof car seat liner | Long journeys; accidents in cars | £10-£20 |
| Wet bag (for soiled clothes) | Drawstring or zipped pouch | £8-£15 |
| Wipes and changing supplies | You already have these | (continuing) |
Total around £100-£150 for the practical kit. The "premium training system" boxes at £80-£150 are usually just rebranded versions of these items.
Two potties beats one
The genuine UK parent recommendation: have a potty available wherever your toddler is. Upstairs in the bathroom, downstairs in the kitchen or living room. The 30-second walk to the only potty in the house is the difference between "made it" and "didn't make it."
Cheap basic potties at £8-£12 each. Don't buy the £30 character-themed ones, the toddler won't care once they're using it; you'll regret the colour scheme later.
Two basic potties: about £20 total. This single decision makes potty training measurably less stressful.
What about the toilet seat reducer
Once toddlers are confidently using the potty, the next step is the actual toilet. A reducer (the smaller seat that fits over the regular toilet seat) makes this work. Some include a built-in step.
Two types:
Standalone reducer (£10-£18): Just the smaller seat. Toddler needs a step stool separately.
Reducer + integrated step (£25-£60): Frame-style with a built-in step (BabyBjorn, MunchKin). More expensive but solves the step problem too.
For UK households: a £15 standalone reducer plus a £15 cheap step stool is the same effective product as a £45 integrated unit. Pick whatever fits your bathroom.
Pull-ups vs cotton training pants
Two different products doing two different jobs:
Pull-ups (Pampers Easy Ups, Huggies, supermarket equivalents): Disposable, absorbent like a thin nappy. Used for nights, outings, naps, situations where accidents would be a real problem.
Cotton training pants (also called "trainers"): Reusable, absorb small accidents but not full ones. Used for daytime, around the house. Toddler feels wet, which is the point during training.
You generally need both:
- 5-7 cotton training pants for daytime
- A pack of pull-ups for nights and longer outings
- Your toddler progressively uses fewer pull-ups as the months pass
Pull-up cost adds up: £10-£15 per pack of 30, lasting maybe 2 weeks. Pampers Pure pull-ups, Huggies, and supermarket own-brand all work fine. Don't pay premium for "training" branded versions.
When potty training in the actually starts
For context (because this is what UK parents actually want to know):
UK NHS guidance: typical signs of readiness from 18 months onwards. Most toddlers are ready between 22-30 months. Some considerably later. Don't push much before 22 months.
Signs of readiness:
- Awareness of being wet/soiled
- Telling you they need to go (or have just gone)
- Dry for 1-2 hours between nappy changes
- Interested in the toilet/potty
If those aren't there: wait. Pushing earlier rarely helps.
For working families: nurseries often won't accept fully un-toilet-trained toddlers in the older rooms. Some nurseries help with training; some require child to be reasonably trained before transferring up. Talk to your nursery.
Waterproof everything
The most underbought product is waterproof bedding/seating protection. Toddlers will have accidents in:
- Beds (more than once)
- Car seats (more than once)
- Sofas (probably)
- Pushchairs (occasionally)
Mattress protectors (£15-£30) and car seat liners (£10-£20) save furniture and prevent the misery of trying to clean a urine-soaked mattress at 11pm.
Waterproof bedding worth the spend:
- Fitted mattress protector (the proper waterproof kind, not the dust mite cover)
- Waterproof bedding underlay for daytime nap
- Wet bags for transport home of soiled clothes
Skip the "training" branded versions of these, a £20 generic waterproof protector does the same job as a £40 branded one.
The night training reality
UK NHS guidance: night dryness develops independently and usually later than day dryness. Most UK children dry at night by age 4; some not until 5-6. Bedwetting up to 7 is medically normal.
Practically: night-time pull-ups continue for months or years after daytime training is complete. That's normal. Don't push through with cotton pants overnight on a child who's still wetting nightly, you'll just create more laundry and make bedtime stressful.
If a child is consistently dry overnight for 2-3 weeks, you can move out of pull-ups to cotton pants, with a waterproof mattress protector firmly in place.
What to avoid
- £30+ "musical" or character-themed potties (toddler doesn't care; you'll dread the noise)
- Training underpants that cost more than £5/pair (cheap supermarket ones do exactly the same job)
- "Reward sticker charts" sold at £10+ (a free printable from BBC Bitesize works the same)
- Premium "potty training systems" boxes at £80+ (£40 of useful items, £40 of marketing)
- Pushing potty training before 22 months without clear readiness signs
- Putting cotton pants on overnight before consistent night dryness
When products don't matter
The repeated message from UK NHS health visitors and paediatric nurses: potty training success doesn't correlate with what you buy. It correlates with:
- Toddler readiness (not pushed too early)
- Consistent approach (everyone caring for child uses same routine)
- Patience with accidents (frustration extends the process)
- Practical kit (not premium kit), having what you need available
The £150 premium system box and the £40 basic kit produce the same outcomes when training goes well. They produce the same problems when training is hard.
A final note on what UK NHS recommends
UK NHS / Health Visitor guidance is genuinely good and free. Available:
- NHS website potty training section
- Health Visitor visits (every UK family entitled)
- ERIC (childhood continence charity, eric.org.uk), free advice for tougher cases
For toddlers struggling beyond age 4-5, or specific issues (consistent constipation, regression after illness, bedwetting age 7+): GP referral. UK NHS continence services exist and are genuinely helpful.
