Skip Hop Infant Bath Tub 3-Stage Grow With Baby Smart Sling MOBY Bathtub, Blue, Age 0+ Review (2026)
Updated September 20, 2026 · Research-based review
Our verdict
A lightweight, whale-shaped tub that uses one Smart Sling locking into two positions to cover newborn through sitting-up stages, in blue. At under 4 pounds it is easy to move and hang dry, but the sling still needs full drying after each bath and the tub takes up shower or bathtub space.

Who this bathtub suits
The Skip Hop MOBY tub uses a single mesh Smart Sling that locks into two ergonomic positions rather than separate removable inserts, covering three stages: newborn from 0 to 3 months up to 15 pounds, infant from 3 to 6 months up to 20 pounds, and sitters from 6 months and up to a 25 pound maximum. It suits parents who want a simpler two-position sling system instead of swapping multiple physical inserts, and who like the whale-shaped design in a blue colorway. Measuring about 27.5 by 19 by 11.5 inches and weighing around 3.6 pounds, it is noticeably lighter than the Fisher-Price 4-in-1 tubs, which matters for parents who need to lift and move the tub between a bathtub and a sink often.
Design, capacity and features
The mesh Smart Sling provides what Skip Hop calls Comfort-Edge support, with an upper position for head-to-toe newborn cradling and a lower position for infants learning to sit up on their own. Once a baby outgrows the sling stages, the sling can be removed for a bare basin stage suited to sitters. A swivel hook is built into the tub for hanging on a shower head, shower bar, or towel rack, which supports both drying and space-saving storage between baths. At roughly 3.6 pounds the tub itself is markedly lighter than four-stage tubs with separate inserts, which some parents may find easier to lift one-handed while holding a baby with the other arm.
Everyday use and care
Because the sling is mesh fabric, it holds water after each bath and needs time to dry fully before the next use, which the built-in swivel hook is designed to support by letting it hang in the shower or on a towel rack. The tub's overall footprint of about 27.5 inches long is fairly wide for a standard tub or shower stall, so parents with a small bathroom should measure their space before assuming an easy fit. Switching between the sling's two locking positions is meant to be tool-free and quick, which helps as a baby's needs change from cradled newborn to a more upright sitting position within the same sling piece rather than a full insert swap.
How it compares with other baby bathtubs
On the site's baby bathtubs guide this blue MOBY tub ranks third of seven, tied on score with both Fisher-Price 4-in-1 print versions and the grey MOBY tub, and just ahead of a newer Skip Hop 4-in-1 model with a slightly lower score. Compared with the Fisher-Price tubs, the MOBY design trades a separate removable infant insert for a single two-position sling, which is a lighter and arguably simpler system but offers fewer distinct physical stages. Its lighter overall weight compared with the Fisher-Price line is a genuine practical difference for parents who move the tub often.
Bottom line on who should buy it
This tub earns the site's score of 8.8 out of 10 as a lightweight, straightforward option for parents who prefer a two-position sling over a multi-piece insert system. It suits households that will hang the tub to dry regularly using the built-in swivel hook, and who have enough shower or bathroom space for its roughly 27.5 inch length. It is a lighter fit for parents who want more granular stage transitions or built-in toys, which this version does not include. For simplicity and low weight, though, it is a strong pick within the site's bathtub lineup.
Frequently asked questions
How is the Smart Sling different from a removable insert?
The Smart Sling is one mesh piece that locks into two positions, an upper newborn cradle and a lower sitting-support position, rather than requiring separate physical inserts for each stage.
What weight range does this tub cover?
The stages run from a 15 pound newborn limit through a 20 pound infant limit up to a 25 pound maximum for babies who can sit up on their own.
How much does the tub weigh?
The tub weighs approximately 3.6 pounds, lighter than four-stage tubs that use separate removable inserts.
How do I dry the sling after a bath?
A built-in swivel hook lets the tub hang on a shower head, shower bar, or towel rack so the mesh sling can air dry fully between uses.
