How to Split Cleaning Supplies With Your Housemates
Nobody moves into a share house excited about buying toilet paper. But somehow, cleaning supplies cause more passive-aggressive tension than almost any other expense. It's fifteen bucks here, twenty there, and before you know it someone's furious because they've bought the dishwashing liquid three times in a row.

How to Split Cleaning Supplies Fairly
- 1
List your shared supplies
Sit down and agree on what counts as shared. Toilet paper, dishwashing liquid, bin bags, sponges, surface spray, and laundry liquid are the usual suspects. Anything personal — fancy shampoo, specific cleaning products for your room — stays off the shared list.
- 2
Set up a supplies kitty
Each housemate chucks in a set amount per week or month. For a 3-person house, $7 to $8 each per week covers the basics comfortably. Keep the money in a jar, a shared account, or track it in Split. When something runs out, whoever's at the shops grabs it.

Assign a shopping roster
Rotate who does the supplies run each week or fortnight. This stops the same person always being the one who notices the bin bags are gone and trudges to Woolies. A roster means everyone takes a turn, no exceptions.

Track what gets bought
Log each purchase. It doesn't have to be obsessive — just the amount and what it was. After a couple of months you'll know exactly what your house spends on cleaning supplies, and nobody can claim they're always the one buying everything.

Review the kitty quarterly
Check if the amount everyone's putting in actually covers what you're spending. If you're always running out of kitty money, bump it up by a couple of dollars each. If there's a surplus, scale it back or use it for a house dinner.
Ways to Split Cleaning Supplies
| Method | How It Works | Best For | Fairness |
|---|---|---|---|
| Equal split | Everyone puts the same amount into a shared kitty, and supplies are bought from that pool. | Most share houses. Cleaning supplies are used roughly equally and the amounts are small enough that equal is fair enough. | High |
| Rotating buyer | Each housemate takes turns buying supplies when they run out. Over time, spending roughly evens out. | Houses where everyone shops regularly and nobody's keeping exact score. Works best with 2-3 housemates. | Medium |
| Income-based | Housemates contribute to the supplies kitty proportional to their income. | Houses with a significant income gap where even small expenses feel different depending on what you earn. | High |
| Zone-based | Split supplies by area of the house. Bathroom supplies are split between the people who share that bathroom. Kitchen supplies are split between everyone. Laundry supplies split between people who use the machine. | Bigger houses with multiple bathrooms where not everyone uses the same facilities. | High |

Tips for Splitting Cleaning Supplies
Buy in bulk at Costco
A share house is one of the few situations where a Costco run actually makes sense. Bulk toilet paper, bin bags, and cleaning products are way cheaper per unit, and between three or four people you'll actually use it all before it expires.
Keep a running shopping list
Stick a shared note on the fridge or use a phone list that everyone can add to. When something's getting low, add it to the list. Whoever does the next shop grabs everything on it. No more texts at 10pm asking if anyone needs anything.
Don't police individual usage
Yes, someone probably uses more toilet paper than everyone else. No, you should not bring this up at a house meeting. The amounts are too small to justify the awkwardness. Let it go and split evenly.
Separate personal from shared
If one housemate only uses eco-friendly $12 dishwashing liquid while everyone else is happy with the $3 stuff, that's a personal choice. Shared kitty covers the standard option. Upgrades are on you.
Include the forgotten items
Bin bags, sponges, aluminium foil, cling wrap, dishwasher tablets — these all add up and someone always ends up buying them without getting paid back. Put them on the shared list from day one.
Common Questions About Splitting Cleaning Supplies
- How much should a share house spend on cleaning supplies?
- For a 3-person house in Australia, expect to spend roughly $15 to $25 a month on the basics — toilet paper, dishwashing liquid, bin bags, sponges, and surface spray. That's about $5 to $8 per person per week. Not a huge amount, but it adds up when one person's always buying.
- Who should buy toilet paper in a share house?
- Everyone, on rotation. Set up a roster or a shared kitty so the same person isn't always the one who notices it's run out. Toilet paper is the number one passive-aggressive share house expense and the fix is dead simple: take turns or pool your money.
- Should cleaning supplies be split equally even if someone cleans more?
- Yes. Splitting the cost of supplies equally is fair because everyone benefits from a clean house, even if they're not the one scrubbing the bathroom. If the issue is that someone never cleans, that's a cleaning roster problem, not a supplies cost problem.
- What cleaning supplies should be shared in a share house?
- Toilet paper, dishwashing liquid, bin bags, sponges, surface spray, laundry liquid, and paper towels are the standard shared items. Personal items like fancy soap, specific skincare products, or specialty cleaning gear for your own room stay off the shared list.
- How do you stop one housemate from freeloading on shared supplies?
- A kitty system fixes this. Everyone contributes the same amount upfront, so nobody can claim they didn't use the supplies. If someone refuses to chip in, have a direct chat. It's five bucks a week — if they won't pay that, you've got a bigger housemate problem.
- Is it worth tracking small expenses like cleaning supplies?
- Absolutely. Small untracked expenses are exactly what causes resentment in share houses. It's never about the $4 bin bags — it's about feeling like you're always the one paying. Logging it in Split takes five seconds and stops anyone quietly keeping score.
Skip the Spreadsheet
Split tracks the little expenses that cause the big arguments. Add your cleaning supplies purchases, see who's actually paid what, and stop being the housemate who silently fumes about toilet paper.
