How to build a zero-waste bathroom in 7 simple swaps

The bathroom is one of the most waste-producing rooms in the home. From plastic shampoo bottles to disposable razors and cotton pads, it’s easy to accumulate a surprising amount of landfill waste without even realising it.

The good news? Creating a zero-waste bathroom doesn’t require a complete lifestyle overhaul or expensive renovations. With a few thoughtful changes, you can significantly reduce waste, lower your environmental footprint and even save money over time.

In this guide, we’ll walk you through 7 simple swaps that will help you transition toward a more sustainable, low-waste bathroom – without sacrificing comfort, hygiene, or style.

What is a zero-waste bathroom?

A zero-waste bathroom aims to minimise waste sent to landfill by replacing disposable, plastic-heavy items with reusable, compostable or refillable alternatives. 

While “zero waste” is an ideal rather than a strict rule, every swap you make helps reduce pollution, plastic waste and resource consumption.

The key is progress, not perfection.

Swap #1: Replace plastic toothbrushes with bamboo toothbrushes

The problem

Traditional plastic toothbrushes are used for just a few months but can take hundreds of years to break down. In Australia alone, millions of toothbrushes end up in landfill every year.

The zero-waste swap

Switch to a bamboo toothbrush with plant-based or recyclable bristles.

Why it works

• Bamboo is fast-growing and renewable
• Handles are biodegradable or compostable
• Performs just as well as plastic toothbrushes

Tip: Remove the bristles before composting the handle, as most bristles are nylon.

Swap #2: Ditch bottled shampoo & conditioner for solid bars

The problem

Shampoo and conditioner bottles are one of the biggest contributors to bathroom plastic waste. Even recyclable plastics often don’t get recycled due to contamination.

The zero-waste swap

Use shampoo and conditioner bars instead of liquid products.

Why it works

• One bar replaces 2–3 plastic bottles
• Long-lasting and travel-friendly
• Free from unnecessary packaging
• Available for all hair types

Many people are surprised by how well solid bars lather and cleanse – often better than conventional formulas.

Swap #3: Replace disposable razors with safety razors

The problem

Disposable razors and cartridge systems are made from mixed materials that are nearly impossible to recycle.

The zero-waste swap

Switch to a reusable stainless steel safety razor.

Why it works

• Razor lasts a lifetime
• Only the metal blades need replacing (fully recyclable)
• Provides a closer, smoother shave
• Saves money over time

Beginner Tip: Use a quality shaving soap or bar and light pressure when starting out.

Swap #4: Swap single-use cotton pads for reusable alternatives

The problem

Disposable cotton pads require water-intensive cotton farming and are used once before being thrown away.

The zero-waste swap

Choose reusable cotton rounds or face cloths.

Why it works

• Wash and reuse hundreds of times
• Softer on skin
• Ideal for makeup removal, toner or cleansing
• Reduces ongoing costs

Simply toss them in the washing machine and reuse again and again.

Swap #5: Use refillable or plastic-free deodorant

The problem

Conventional deodorants come in plastic packaging that rarely gets recycled and often contain unnecessary chemicals.

The zero-waste swap

Opt for natural deodorants in refillable, compostable or glass packaging.

Why it works

• Less plastic waste
• Fewer synthetic ingredients
• Effective odour control using natural minerals
• Better for sensitive skin

Your body may need a short adjustment period, but most users find natural deodorants work just as well.

Swap #6: Choose plastic-free toilet paper & bathroom cleaning products

The problem

Traditional toilet paper is often wrapped in plastic and made from virgin forest materials. Cleaning products also come in single-use plastic bottles.

The zero-waste swap

• Use recycled or bamboo toilet paper wrapped in paper
• Switch to refillable or concentrated cleaning products

Why it works

• Reduces deforestation
• Less plastic waste
• Concentrates last longer and reduce shipping emissions

Refill stations and cleaning tablets are becoming more widely available across Australia.

Swap #7: Replace disposable period products with reusable options

The problem

Pads and tampons are single-use items containing plastic that can take centuries to break down.

The zero-waste swap

Try menstrual cups, reusable pads or period underwear.

Why it works

• One menstrual cup can last up to 10 years
• Significantly reduces waste and cost
• Safe, hygienic and comfortable
• Ideal for active lifestyles

This single change can prevent thousands of disposable products from entering landfill over a lifetime.

Extra tips for a low-waste bathroom

Even beyond the 7 swaps, small habits can make a big difference:

• Buy in bulk or refill where possible
• Choose multi-purpose products
• Avoid “greenwashing” by checking materials and packaging
• Use what you already have before replacing items

Remember, the most sustainable product is the one you already own.

Why start with the bathroom?

The bathroom is a great place to begin your zero-waste journey because:

• Swaps are simple and affordable
• Products are used daily, creating visible impact
• Changes often save money long-term
• Habits form quickly

For many people, bathroom swaps are the gateway to a more eco-conscious lifestyle throughout the home.
