Foaming Castile Hand Soap Concentrated Refills - 4 Pack

Refill beautifully. Again and again.

Already have your foaming bottle? This 4-pack of 2 oz. Foaming Castile Hand Soap Refills is designed to keep every sink stocked—without another plastic bottle in sight.

Made with our gentle, plant-based Castile soap, each refill creates a rich, effective foam that cleans thoroughly while remaining kind to skin. No synthetic detergents. No unnecessary fillers. Just simple ingredients that do the job well.

Each 2 oz. concentrate makes one full 12 oz. bottle of foaming hand soap.
Pour into your reusable bottle, top with water, and gently swirl to combine.

Four refills = four full bottles of soap.
Simple. Practical. Low-waste.

Keep one at every sink—kitchens, bathrooms, and guest spaces—or store a few away so you never run out.

And because it’s true Castile soap, it isn’t limited to the sink.

These 2 oz. bottles are perfect for travel—use a small amount in the shower, at the campsite, or by the kitchen sink when you’re away from home. A little goes a long way.

Each 2 oz. refill is a pre-measured portion of our concentrated Castile soap—designed to make refilling simple and consistent.
