Take a quick look at your bathroom bin. What do you see? Plastic shampoo bottles, disposable razors, old toothbrushes, and maybe a tangle of dental floss. It’s amazing how much plastic waste comes from such a small room!
Many people think “zero-waste” is difficult, expensive, or extreme. But at WiseHomist, we know the truth: a zero-waste bathroom is actually a frugal bathroom.
It’s not about being a perfect environmentalist overnight. It’s about making small, wise changes that save you money and help the planet. Here are 5 incredibly easy swaps you can make to get started.

1. The Swap: Solid Shampoo Bar
Replaces: Plastic Shampoo & Conditioner Bottles
This is one of the easiest and most impactful swaps. A single solid shampoo bar can replace 2-3 full-sized plastic bottles of liquid shampoo.
- Why it’s a Wise Swap:
- Frugal: While a bar might cost a little more upfront, it lasts so much longer (often 60-80 washes!). You’ll save money in the long run.
- Zero-Waste: They come packaged in a simple paper box, or not at all. No plastic.
- Travel-Friendly: They’re solid, so you can throw one in your bag without a single worry about spills or liquid limits at the airport.
2. The Swap: The “Forever” Safety Razor
Replaces: Disposable Plastic Razors & Cartridge Heads
This is the ultimate frugal swap. Those colorful disposable razors or the ones with replaceable plastic cartridges are a huge source of waste and a constant expense.
- Why it’s a Wise Swap:
- Incredibly Frugal: A good safety razor is a “buy it for life” item. A pack of 100 high-quality, all-metal replacement blades often costs less than a single pack of 4 plastic cartridges. The savings are massive.
- Zero-Waste: The razor lasts a lifetime, and the metal blades are 100% recyclable (just collect them in a small, safe tin).
- A Better Shave: Many people find they get a closer, less-irritating shave once they learn the simple technique.
3. The Swap: Bamboo Toothbrush
Replaces: Plastic Toothbrushes
This is the simplest one-for-one swap you can make. Every single plastic toothbrush you’ve ever used still exists somewhere on the planet.
- Why it’s a Wise Swap:
- Eco-Friendly: The handle is made from bamboo, which is a fast-growing, sustainable plant. When you’re done, the handle is fully compostable.
- Simple & Accessible: They look, feel, and work just like your old plastic brush. No learning curve required.
- (Just Remember: The bristles are usually nylon, so you’ll need to pull them out with pliers before composting the handle.)
4. The Swap: Reusable Cotton Rounds
Replaces: Single-Use Cotton Balls & Makeup Wipes
Whether you’re removing makeup or applying toner, those single-use cotton pads add up quickly.
- Why it’s a Wise Swap:
- Frugal: You buy one set of 10-20 reusable rounds, and you’re set for years. Just toss them in a small mesh bag and put them in the laundry with your towels.
- Gentle on Skin: They are often made from soft materials like organic cotton or bamboo fleece, which are less abrasive than disposable wipes.
- WiseHomist DIY Hint: This is a fantastic and simple project to make yourself from an old t-shirt, towel, or flannel. Keep an eye out for our upcoming DIY on this!
5. The Swap: Toothpaste Tablets or Powder
Replaces: The Plastic Toothpaste Tube
Those toothpaste tubes are notoriously difficult to recycle. Toothpaste tablets (or tooth powder) are a brilliant modern alternative.
- Why it’s a Wise Swap:
- Zero-Waste: They come in a reusable or recyclable glass jar.
- Perfect Portions: You use exactly what you need—one tablet per brush. No more squeezing out too much (or too little).
- Travel-Friendly: No liquids, no mess. Just count out how many tablets you need for your trip and go.
Conclusion
See? It’s not about doing everything at once. It’s about making one wise choice at a time. Start with the swap that seems easiest to you.
Your wallet—and the planet—will thank you.
