Cloth Diaper Pail Liners | Fit, Types & Wash Tips

Getting the right liner for your setup matters more than most new cloth-diapering parents expect. A liner that’s too small, too wide, or made from the wrong material turns a good system into a leaky, smelly chore. The working approach is to match your pail’s model and size first, then pick the liner type that fits your wash routine—reusable waterproof, disposable, or breathable mesh.

What Are Cloth Diaper Pail Liners?

A pail liner sits inside the diaper pail or a tall kitchen bin, collecting used cloth diapers until wash day. Reusable liners are typically made from polyester with a waterproof coating of PUL (polyurethane laminate) or TPU (thermoplastic polyurethane). These liners are machine-washable and built to last through hundreds of cycles. Disposable liners come as refill bags for specific pail systems like the Diaper Dekor Eko, and they’re thrown away with each load of trash. Breathable mesh liners are less common—they let air circulate but do not contain odors as well as waterproof options.

Which Liner Fits Your Diaper Pail?

Fit is the most common mistake people make. Some liners are designed for specific brand-name pails, while others work with any standard 13-gallon tall kitchen trash can.

• Brand-specific liners—like the Diaper Dekor Cloth Diaper Pail Liner 2-Pack—are built to fit the Dekor Plus and Dekor Eko Plus pails exactly. These liners have a drawstring closure and a waterproof coating, and the opening measures approximately 14 inches. Diaper Dekor’s official site lists compatible models.
• Generic liners work with any standard 13-gallon bin or unbranded diaper pail. Most reusable wet bags sold as pail liners fall into this category. They are typically wider and taller than the brand-specific versions.
• BumGenius also offers a diaper pail liner designed to fit their own pail system, with a drawstring and waterproof fabric.

Before you buy, measure the interior height and diameter of your pail. Assuming all liners fit all pails is the fastest route to frustration. If you are shopping for your first setup, our tested roundup of the best cloth diaper pails can help you choose the right one from the start.

Reusable vs. Disposable: Which Should You Use?

Your wash routine and budget decide this. Reusable liners cost more upfront—usually $15–$25 for a two-pack—but they replace disposable bags entirely. They go into the washing machine with the diapers, then dry and go back into the pail. Most reusable liners are PVC-free and use PUL or TPU waterproofing; some use recycled materials. Odor and leak resistance are product claims, not guarantees, so check the product specifications and user reviews for real-world performance.

Disposable liners are convenient for travel, heavy-soil loads, or families who prefer not to wash another fabric layer. The Diaper Dekor Eko uses a disposable refill system, and the bags are thrown away with each diaper change load. The trade-off is ongoing cost and plastic waste.

How To Wash And Care For Reusable Liners

Wash instructions are product-specific, but a few rules apply to almost every waterproof liner. Close the drawstring or zipper before washing to keep the liner from tangling. Wash in warm or hot water with your regular cloth-diaper detergent. Do not use fabric softener—it coats the waterproof coating and reduces effectiveness over time. Dry on low heat or hang to dry; high heat can damage the laminate. If the liner starts to leak or the inner coating peels, it is time to replace it, not repair it.

FAQs

Can you use any trash bag as a diaper pail liner?

Standard kitchen trash bags lack the waterproof barrier and drawstring closure that reusable diaper pail liners provide. A regular bag will leak moisture and odors through the pail and is not designed for multiple washes. If you prefer disposables, use the liner bags made for your pail model.

Do cloth diaper pail liners control odor?

Reusable waterproof liners with PUL or TPU coatings contain odors better than mesh or thin disposable bags, but no liner is odor-proof. The key is reducing the time diapers sit before washing—every two to three days is typical. Adding a small open container of baking soda in the pail can help in warmer weather.

Can pail liners go in the dryer?

Most reusable liners can be dried on low heat, but high heat damages the waterproof laminate. The safest approach is to hang the liner to dry, which extends its life significantly. Check the tag on your specific liner before using the dryer.
