Quick answer
Choose the 500ml aluminium bottle if you want a compact, recyclable option for occasional use or travel. Pick the 20L refill if you have a large household or high usage and want to minimize plastic waste and cost per wash.
Cost per wash: why 20L saves more
The 20L refill costs $154.79 compared to $10.49 for the 500ml bottle. At the same price per liter, the 20L is significantly cheaper per wash, making it a smart choice for frequent users or large families.
However, the upfront investment is higher. If you're on a tight budget, the 500ml bottle is more accessible, and you can always upgrade later.
Storage and handling trade-offs
A 20L container is heavy and requires floor space, so make sure you have a suitable storage area. The 500ml aluminium bottle is lightweight and fits neatly on a shower shelf or bathroom cabinet.
For the 20L, you'll need a pump or a smaller bottle to decant into for daily use. This adds a bit of effort but is manageable with a simple transfer routine.
Eco impact: both reduce waste, but differently
The 500ml bottle is made of recycled and infinitely recyclable aluminium, which is great for the environment if you recycle properly. The 20L is part of the plastic-reducing refills range, cutting down on the number of containers you buy over time.
If you already recycle diligently, the aluminium bottle is a low-waste choice. If you want to minimize packaging overall, the 20L refill uses less packaging per liter.
Decision rules: choose your size
- Choose 500ml if...: You have a small household, use shampoo occasionally, or want a lightweight bottle for travel or small bathrooms.
- Choose 20L if...: You have a large family, use shampoo daily, or want the lowest cost per wash and minimal packaging waste. Before buying, measure your storage space and ensure you have a pump or smaller bottle for daily use.
- Budget check: If the upfront cost of 20L is too high, start with 500ml and switch to refills later when you can save more.
