How Refill Boxes Work (and How to Set Up a Refill Station at Home)

Common Good 2.5 gallon refill box with reusable spigot on a shelf.

People hear "refill box" and picture something more complicated than it is. Here's exactly how refill boxes work, start to finish — the setup, the one warning that matters, and how the empty liner comes back to us to be reused.

What a refill box actually is

A refill box is a bag-in-box — the same format that's held everything from wine to industrial soap for decades, because it works. Inside a 2.5-gallon kraft carton is a sealed liner full of product and a reusable spigot. The box is 100% post-consumer recycled cardboard, printed with environmentally friendly inks, and held together with no glue — it slots together, and apart, easily. It weighs about 22 pounds and measures 10 x 10 x 10 inches. That's your refill station. No plumbing, no stand, nothing else.

How to set up a refill station at home

Take the box out of its shipping carton and follow four steps:

  1. Tip the box onto its back.
  2. Unscrew the shipping cap — and save it, you'll need it later.
  3. Screw on the spigot.
  4. Stand the box upright with the tap facing front.

Stack boxes up to three high on a dry, temperature-stable shelf, and a pantry or laundry-room shelf becomes a refill station.

Read this part: Tip the box onto its back before you unscrew the cap. Opening it upright, with 2.5 gallons of soap behind the opening, results in — in the exact words of our own instructions — very soapy shoes. Consider yourself warned.

Using your refill box

Push the tap to fill your bottle; push it to the right to shut off. Spigots can drip, so keep a small dish or cloth underneath as a drip catcher. Store somewhere dry and temperature-stable, and if a product ever freezes, warm it gently and shake. You're refilling from the same beautiful bottles you already own — the good-looking thing stays on your counter, and the 22 pounds of soap lives quietly on a shelf.

When the box is empty: the Full Circle Program

When a liner is empty, you don't throw it away — you send it back, we sanitize it, and we reuse it. Keep the spigot (rinse it, dishwasher's fine, dry it, reuse it), collapse and recycle the cardboard, then rinse and drain the empty liner, fold it flat, and screw the saved cap back on. Save up a minimum of four, box them, and request a prepaid return label — we email it within a day or two. Prefer to recycle it yourself? The liner is LDPE type 4 plastic and curbside recyclable.

  • Zero single-use plastic when you return the liner
  • 100% post-consumer recycled cardboard
  • Fully recyclable cardboard and plastic components
  • 1 reusable spigot, box after box
  • Flat-packed packaging = lower freight emissions at manufacturing
  • Same safe, clean formula in bulk

That's the entire system. One box, one spigot, a stack on a shelf, and a liner that comes back to us when it's done. You buy less plastic — not less product.

FAQ

How does a refill box work?

A Common Good refill box is a bag-in-box: a 2.5-gallon recycled cardboard carton holds a sealed liner of product and a reusable spigot. You attach the spigot, stand the box upright, and dispense straight into your own bottles.

How do you set up a refill station at home?

Tip the box onto its back, unscrew the shipping cap (save it), screw on the spigot, and stand it upright with the tap facing front. Boxes stack up to three high on a dry shelf.

How much does a 2.5-gallon refill box hold?

It holds 2.5 gallons and replaces roughly 20 standard bottles. And when you return the liner, you use no single-use plastic. 

Can you reuse the spigot?

Yes. It's reusable and dishwasher safe. Rinse, dry, and save it for your next box.

What do you do with the empty liner?

Rinse and flatten it and send a minimum of four back with a prepaid label through our Full Circle Program — we sanitize and reuse them. Or recycle it curbside as LDPE type 4 plastic.

Why won't the box dispense, or why did it leak?

Push the tap to the right to shut it off, and always tip the box onto its back before removing the cap — opening it upright leads to very soapy shoes.
