BabyDam
Bathwater Barrier
7.2/10 overallAbout £27
A suction-mounted barrier that dams off a section of the adult bath so babies can bathe safely in a small, shallow pool without a separate baby bath.
The verdict
BabyDam's Bathwater Barrier, around £27, seals off a section of a standard bathtub with suction, creating a small shallow pool so you use far less water without buying a separate baby tub. It suits families who want to cut water use and skip storing a dedicated bath, but it gives no built-in newborn support, and the suction seal can struggle on older or textured surfaces.
BabyDam works by sealing off a section of a standard adult bathtub with a suction-cupped plastic and silicone barrier, creating a small, shallow pool for your baby without needing a separate tub at all. Fill just the sectioned-off area and you use a fraction of the water and time a full bath would take.
Against the Shnuggle Baby Bath in this category, the trade-off is support versus space: Shnuggle's curved backrest holds a newborn securely from birth with no extra kit, while BabyDam gives no built-in support at all — you're bathing baby directly in the adult tub, just in a smaller pool of water, so you still need to hold or prop them yourself early on. What BabyDam wins back is storage: there's no separate tub to find room for once your baby outgrows it.
The suction seal is the main practical weak point. It works reliably on smooth, clean acrylic or enamel baths, but older or textured surfaces can let water seep past the barrier, and the seal needs re-checking each time you set it up.
It's a strong pick for families who already bath their baby in the big tub and mainly want to cut water use and avoid buying (and storing) a dedicated baby bath, rather than families who want maximum newborn support out of the box.

How we scored it
Safety & Support
How securely it holds a newborn or wriggling baby during a wash.
No built-in newborn support — unlike the Shnuggle bath's curved backrest, babies need to be held or propped separately, and suction-cup security varies with bath surface.
Ease of Use
How easy it is to fill, empty, lift and use one-handed.
Space & Storage
How much bathroom or nursery space it takes up and how easily it folds or stacks away.
Needs zero permanent storage space since it uses your existing bath — the strongest option in this category for small bathrooms.

Frequently asked questions
Does the BabyDam barrier support my baby in the bath?+
No — unlike the Shnuggle bath's curved backrest, it gives no built-in support at all, so you're bathing baby directly in the adult tub, just in a smaller pool of water, and you still need to hold or prop them yourself early on. It scores 6/10 for safety and support.
How reliable is the suction seal?+
It works reliably on smooth, clean acrylic or enamel baths, but older or textured surfaces can let water seep past the barrier, and the seal needs re-checking each time you set it up.
Does the BabyDam barrier need storage space?+
No — it scores a perfect 10/10 for space and storage, the strongest option in this category for small bathrooms, since it folds flat and needs zero permanent storage space, using your existing bath instead of a separate tub.
How much water does the BabyDam barrier save?+
It cuts water used per bath significantly, since you only fill the small sectioned-off area rather than a full bath, using a fraction of the water and time a full bath would take.
