Waterproof Diaper Covers for Girls Size 5t - Leakproof Potty Training

Our review of these waterproof diaper covers for girls finds them most useful for parents who need a reliable outer layer during potty training and light nighttime use. The single biggest reason to buy is the truly waterproof PUL/TPU fabric combined with a stretchy waist and leg openings that reduce side and waistband leaks; in practical use this cover holds small to moderate accidents and fits over regular training pants or underwear without bulk. It reads and wears like a simple rubber swim diaper cover while staying machine washable for repeated use.

Key Features

• Waterproof fabric: The 100% PUL outer with breathable TPU prevents urine from soaking through while remaining durable for everyday use.
• Elastic waist and legs: A highly stretchy waistband and leg openings create a snug seal that reduces side leakage when a toddler runs and plays.
• Reusable and machine washable: The cover is designed for repeated cleaning, saving money versus disposables and keeping care simple.
• Fits over training pants: Intended to be worn over regular toddler underwear or potty training pants to contain accidents and protect bedding or furniture.
• Thicker new fabric: A newer, thicker material improves longevity and gives a more reliable barrier than thinner covers.

Who It's For

This product is a practical match for parents of toddler girls in size 5t who need a waterproof outer layer during daytime potty training or short naps. It is especially helpful for families who want a reusable, washable option that looks like swim underwear rather than bulky diapering gear.

Parents who need heavy overnight protection or a product that absorbs urine should look for absorbent training pants or mattress protection instead, since this cover is a containment layer rather than an absorbent solution.

Pros & Cons

Pros

• Durable waterproof fabric that generally stops leaks from escaping outer clothing and bedding.
• Elastic waist and leg openings give a comfortable, snug fit for active toddlers.
• Machine washable and reusable, which reduces ongoing cost compared with disposables.
• Attractive new designs that look like regular underwear, making toddlers more willing to wear them.

Cons

• Not an absorbent product, so it will not replace training pants for heavy overnight accidents.
• Some users may find fit or sizing varies slightly; shoppers should verify that size 5t matches their child's measurements.
