Bathroom

The four highest-impact, lowest-effort bathroom swaps are: a bamboo toothbrush instead of a plastic one, a shampoo bar instead of a bottled shampoo, a safety razor instead of disposable cartridge razors, and reusable cotton rounds instead of disposable pads. These four changes eliminate most of the ongoing plastic waste a bathroom generates without changing your routine.

Yes, for most people. Natural deodorants control odour through baking soda, magnesium, zinc, or mineral crystal rather than blocking sweat with aluminium compounds. Most people find them fully effective after a brief adjustment period of one to two weeks when switching from antiperspirant. EcoWarehouse stocks paste, stick, and crystal formats to suit different preferences.

Shampoo bars work well in most NZ water conditions. In areas with harder water, a slight residue may build up over time. An occasional rinse with diluted apple cider vinegar (one tablespoon per cup of water) resolves this. Most customers find shampoo bars fully effective from the first use with no adjustment needed.

Bamboo toilet paper is generally considered the most sustainable option: bamboo grows rapidly without pesticides and does not require replanting after harvest. Recycled content toilet paper is a strong alternative and often more affordable. Both are significantly better than conventional virgin wood pulp toilet paper.

The average NZ bathroom generates roughly 30 to 50 plastic items per person per year, including shampoo and conditioner bottles, body wash bottles, toothbrushes, cotton bud sticks, razor handles, and disposable pad packaging. Switching the most frequently replaced items — toothbrush, shampoo, body wash, and razors — to plastic-free alternatives reduces this by around 80 percent.

For personal care items like toothbrushes and cotton buds, bamboo handles are compostable at end of life, whereas plastic handles persist in landfill for hundreds of years. Bamboo is a fast-growing grass that requires no replanting, no pesticides, and significantly less land than wood. For bathroom accessories and fixtures, bamboo is durable and moisture-resistant with proper care.
