Frida Baby 4-in-1 Grow-with-Me Baby Bathtub with Removable Bath Seat & Backrest Review (2026)

One tub meant to last from newborn to toddler

Frida Baby designs this tub to cover four stages from birth through about 24 months, using an adjustable smart sling and a removable bath seat and backrest rather than a single fixed shape. The tub measures about 28 inches long by 18.25 inches wide by 9.5 inches high and weighs around 7.8 pounds empty, with a stated capacity of up to 25 pounds. That makes it a fit for parents who want to buy one bathing setup and keep reconfiguring it as their child grows, instead of replacing a newborn tub with a sit-up tub and then a toddler tub in sequence. Families tight on storage should weigh the convenience of one tub against its larger footprint compared with a folding infant tub.

How the four stages and adjustable sling work

In the earliest stage, the sling keeps a newborn cradled and supported; as the baby grows, the sling can be adjusted to give more leg room. Around 9 to 12 months, the sling converts into a more upright seat for a baby who can sit independently, and from about 12 to 24 months the sling can be removed entirely to create an open toddler tub. Frida states the tub has a non-slip base, and is BPA-free, phthalate-free and PVC-free. The sling material is machine washable and described as quick-dry, which matters since it is in direct contact with a wet baby at every bath. Frida's own instructions should guide exactly when to move between stages rather than relying on age alone.

Living with the extra pieces day to day

Because this is a multi-stage system rather than a single molded tub, there are more parts to manage: the tub itself, the sling, and the removable seat and backrest, each needing a spot to dry and store between baths. The sling's quick-dry, machine-washable design is meant to make that upkeep manageable, and the non-slip base is intended to help keep the tub steady in a bathtub or on a counter. Unlike a fold-flat infant tub, this one is not described as folding down, so families in very tight bathrooms should plan a permanent or semi-permanent spot for it. Always follow Frida Baby's included instructions for supervision and correct sling positioning at each stage.

How it compares with foldable single-stage tubs

Against the OXO Tot Splash and Store and Stokke Flexi Bath, both of which fold flat for storage but cover a narrower or differently structured age range, the Frida Baby trades folding convenience for a longer usable life through toddlerhood without needing a second tub. The Summer Foldaway sits somewhere between the two, offering a removable inclined positioner in a tub that does fold for storage. Parents most focused on saving cabinet space should lean toward a folding rival, while those who want to avoid buying multiple tubs over two years will likely prefer this multi-stage approach.

Verdict: fewer tub purchases, more pieces to store

For parents who want one tub to handle newborn through toddler stages, the Frida Baby 4-in-1 earns its our score of 7.9 out of 10 for its adjustable sling and seat system and non-slip base. Anyone in a small bathroom without a permanent spot for a non-folding tub, or who prefers fewer loose parts to track, should consider a folding single-stage tub instead. For most families, the tradeoff of extra pieces is balanced by not needing to shop for a new bathtub every few months as the baby grows.
