You’ll find a wide selection of compatible replacement straws for popular 20 oz, 30 oz, and 40 oz tumblers on Walmart. Browse the replacement straw category or use the search bar. To pick the right one, check:

• Size compatibility: Many listings call out 20/30/40 oz and list lengths like 12" or 14".
• Lid style: Standard straw ports vs. flip-lid designs may use different shapes.
• Material: Plastic, silicone, or stainless steel options are available, often in multipacks with cleaning brushes.
• Care: Some note “dishwasher safe.”

Shipping and pickup options vary by location and inventory. Reviewing the product details section can help confirm fit before you order.

You can shop standalone straw packs on Walmart without buying a new tumbler. Look for “replacement” or “compatible” in the product title, then:

• Match the size: Select options labeled for 20 oz, 30 oz, or 40 oz cups.
• Check length/diameter: Product pages list measurements; wider straws can suit smoothies and milkshakes.
• Pick materials: Choose rigid plastic, flexible silicone, or metal based on your preference.
• Extras: Many multipacks include cleaning brushes or silicone tips.

Add to cart for delivery or pickup, depending on availability. Reviewing the Q&A and item description can help ensure compatibility with your lid style.

Sizing varies by cup height and lid, so it helps to check product specs. On Walmart, common options include 12-inch straws for taller tumblers and even 14-inch extra-long silicone versions for larger bottles. To choose:

• Measure: Estimate from the lid opening to the bottom of your cup, adding a little clearance.
• Verify labeling: Many listings clearly state 20/30/40 oz compatibility.
• Consider diameter: Standard diameters work for water; wider versions can handle thicker drinks.
• Mind the lid: Flip-lid designs may require a specific straw angle or shape.

Checking the item’s length and diameter on the product page can help you find a comfortable fit.

Cleaning is straightforward, and many options on Walmart are labeled “dishwasher safe.” Care can differ by material, so it’s helpful to review each item’s description:

• Plastic: Some can go on the top rack; hand-washing with a brush helps with residue.
• Silicone: Often dishwasher friendly and flexible, making brush cleaning easier.
• Metal: Typically durable; a quick rinse plus a brush can help with thicker drinks.

For best results, rinse soon after use, run a brush through the length, and let pieces air-dry. An occasional warm, soapy soak can help with buildup. Always follow care notes on the product page, as recommendations can vary.

Some silicone straws listed on Walmart are described as customizable length and can be cut to fit. If the product page confirms this feature, you can:

• Measure first: Insert the straw through the lid, mark the desired length, and remove.
• Cut carefully: Use clean scissors and trim from the bottom end for a smooth edge.
• Test the seal: Make sure the trimmed straw sits well in the lid and doesn’t affect any stopper features.

Trimming isn’t generally recommended for rigid plastic or metal straws. If you’re unsure, checking the item description and customer reviews can provide helpful context. Availability of customizable styles may vary.
