Your bathroom is quietly one of the most wasteful rooms in your home — and also one of the easiest to transform. The average person generates roughly 4.5 lbs of trash per day, and a big chunk of that comes from single-use bathroom products.
The good news: zero waste bathroom swaps are genuinely easy, most of them save money, and you don’t have to do everything at once. Here are 12 swaps that actually work in 2026.
Why Start With the Bathroom?
The bathroom is ideal for zero waste beginners because:
- Products run out regularly, giving you natural swap points
- Most swaps cost the same or less long-term
- The alternatives have improved dramatically in the last few years
- You’ll see the impact immediately in your trash can
The 12 Best Zero Waste Bathroom Swaps
1. Shampoo Bar Instead of Bottled Shampoo
Modern shampoo bars (not the old soap bars that destroyed your hair) clean just as well as liquid shampoo and last 2–3x longer. One bar replaces 2–3 bottles.
Best picks: HiBar, Ethique, Love Beauty and Planet bars
Savings: ~$20–30/year per person
2. Conditioner Bar
Same concept as shampoo bars. Ethique’s conditioner bars are the gold standard — one bar equals about 3 bottles of conditioner.
Pro tip: Store on a soap dish to prevent melting, not in the stream of the shower.
3. Bamboo Toothbrush
Americans throw away 1 billion plastic toothbrushes per year. Bamboo toothbrushes work identically, cost about the same ($3–5 each), and the handle is compostable.
Best picks: Brush with Bamboo, WooBamboo, Quip (bamboo version)
4. Toothpaste Tablets or Powder
Toothpaste tubes are almost impossible to recycle. Toothpaste tablets come in glass or aluminum tins — just chew, wet your brush, and go. They work great once you adjust (takes about a week).
Best picks: Bite Toothpaste Bits, Unpaste, Georganics tooth powder
Cost: Similar to mid-range toothpaste (~$10–15 for 3 months)
5. Safety Razor Instead of Disposable Razors
This might be the biggest money-saver on this list. A good safety razor costs $25–40 upfront, but replacement blades cost 10–25 cents each — versus $3–5 per disposable cartridge.
Payback period: 3–4 months. Then you save $50–100/year indefinitely.
Best picks: Merkur 34C, Edwin Jagger DE89, Henson AL13
6. Reusable Cotton Rounds
Disposable cotton pads are used once and tossed. Reusable organic cotton rounds ($12–20 for a set of 16) are washed with your laundry and last years.
Bonus: They’re softer on your skin than disposable pads.
7. Bar Soap Instead of Liquid Hand Soap
Bar soap uses far less packaging and often less water in manufacturing. It lasts longer per oz than liquid soap. Just get a good soap dish that drains — that’s the secret to bar soap lasting.
Cost: Usually cheaper per wash than pump soap.
8. Menstrual Cup or Period Underwear
A menstrual cup ($25–40) replaces hundreds of dollars in tampons and pads every year. The average person spends $150–300/year on period products — a cup lasts 10 years.
10-year savings: $1,200–$2,600
Best picks: Diva Cup, Saalt, Lunette
Period underwear (Thinx, Modibodi) is a great complement or alternative if cups aren’t your preference.
9. Refillable Deodorant
Plastic deodorant sticks are hard to recycle. Refillable options (like Wild, By Humankind, or Meow Meow Tweet) send you a new insert — no new container every time.
Cost: About the same as standard deodorant, sometimes less on subscription.
10. Solid Lotion Bar or Refillable Body Lotion
Solid lotion bars (beeswax, shea butter, oils) melt on skin contact and leave zero packaging waste. For those who prefer liquid lotion, brands like Plaine Products offer aluminum bottle refills by mail.
11. Compostable Floss
Traditional dental floss is nylon or PTFE in a plastic container — both non-recyclable. Silk or cornstarch-based floss in cardboard/glass containers is now widely available and works just as well.
Best picks: Cocofloss (recyclable case), Dental Lace, Lucky Teeth
12. DIY or Bulk Cleaning Products
Toilet bowl cleaner, tub scrub, glass cleaner — most can be made with baking soda, white vinegar, castile soap, and essential oils. Or buy in bulk at a refill store and bring your own containers.

How to Start Without Feeling Overwhelmed
The zero waste trap is trying to change everything at once. Don’t do that.
The better approach: Replace one thing at a time as it runs out. When your shampoo bottle is empty, try a shampoo bar. When your razor cartridge dies, try a safety razor. Within 6 months, your bathroom will look completely different — and you’ll barely have noticed the transition.
