Search for "plastic-free bathroom" and you'll drown in tips. The problem is that far from every swap makes a difference – some barely save any plastic, and a few are pure greenwashing, where a green word hides the fact that the product is still plastic.
We sell plastic-free oral care, so we have every reason to praise every "eco" swap in the book. But we'd rather be straight with you: here are five bathroom swaps that actually count – and two popular ones that don't, however green they sound.
The 5 swaps that actually make a difference
1. Plastic toothbrush → bamboo with natural bristles
The obvious one, and still the one with the biggest effect: you replace a product that is made entirely of plastic and that you throw away roughly every three months – around four plastic toothbrushes per person per year, year after year. A bamboo handle, by contrast, can be composted.
But be careful about one thing: the handle is only half the toothbrush. On most "bamboo toothbrushes" the bristles are still nylon – that is, plastic. A truly plastic-free swap requires the bristles to be a natural material too (natural keratin bristle). More on why in our comparison of boar bristle and nylon.
2. Nylon dental floss → silk or plant-fibre floss
Almost all ordinary dental floss is nylon, and the "glide" floss that feels smooth is often coated with PTFE – the same chemical family as PFAS. That's plastic you pull between your teeth every evening. Switch to floss made of natural silk or plant fibre, ideally in a refillable holder so you replace the reel instead of throwing away a whole plastic box. Check that it is free from nylon, PTFE and PFAS.
3. Plastic bath sponge → loofah
A synthetic sponge or shower pouf is plastic that slowly wears down into microplastics straight down the drain. A loofah is the opposite: it is the fruit of the luffa plant – pure plant fibre, which you compost when it's worn out. Just check that it's real luffa and not a synthetic sponge marketed as "natural".
4. Plastic deodorant → alum stone
An alum stone is a mineral salt – a bare stone with no plastic packaging, a single ingredient, that lasts a long time. The real difference from an ordinary antiperspirant lies in how it works: an antiperspirant with aluminium chlorohydrate forms large gel plugs that block the sweat glands and stop sweat. Alum (potassium aluminium sulphate) doesn't do that – its aluminium is stabilised by the sulphate and so doesn't build the large plug-forming structures, which means alum doesn't block the pores but only counteracts the bacteria that cause sweat odour. So it's a deodorant, not an antiperspirant.
5. Plastic tongue scraper → metal tongue scraper
If you use a tongue scraper, choose one in stainless steel instead of plastic. It's hygienic, easy to rinse and lasts for years, while the plastic version is yet another thing that gets thrown away sooner or later. Tongue scraping can reduce coating and freshen breath, but it's a complement to brushing – not a miracle cure, and we promise no medical effects.
2 swaps that look green – but aren't
❌ "Biodegradable" or "compostable" plastic
It sounds perfect, but read the small print. Most "compostable" plastics (such as PLA) only break down in an industrial composting facility with high heat – not in your garden compost and certainly not in nature, where they can stay almost as long as ordinary plastic. And if they end up in plastic recycling, they can ruin the whole batch. So "biodegradable" rarely means "disappears on its own". A genuinely natural material (bamboo, keratin, silk, luffa) beats a labelled plastic every time.
❌ The charcoal toothbrush
The black "charcoal toothbrush" looks natural and is often marketed as both eco-friendly and whitening – but the bristles are ordinary nylon with activated carbon mixed in. So it's still plastic, just like a completely ordinary nylon brush, only coloured black. A published dental study describes them plainly: binchotan charcoal in nylon bristles. And the whitening effect? It is not scientifically proven. A "charcoal" brush is therefore neither more plastic-free nor more effective – just darker marketing.
The pattern: how to recognise a real swap
The difference between a genuine swap and a fake one is simple once you see it:
- A real swap replaces a use-and-throw plastic with something natural or durable that you actually use for a long time – and that can break down or be recycled cleanly afterwards.
- A fake swap replaces one single-use plastic with another, or hides plastic behind a green word such as "bio", "eco" or "bamboo".
So ask two questions before you buy: What is it actually made of? (not what the packaging says) and what happens to it when it's finished? If the product passes both questions, it's a swap worth making.
