Overview
Parents bathing a newborn who want one tub for the toddler years get a plastic bath with an adjustable bump and a contoured back wall. The tub rests in a double sink or a full size bathtub, and the bump moves to suit a reclining infant or a seated toddler.
Adjustable support earns its place: one tub covers the newborn months and the sitting stage without buying a second seat. Non-slip foam and the contoured back hold a small baby steady. On the downside, the listing gives no weight limit and no fit measurements for specific sinks.
Who it's for
Families with a double kitchen or bathroom sink get the most from the compact shape. Caregivers who want a large freestanding basin for an older toddler to play in should look for a bigger tub.
Pros and cons
- Adjustable bump tunes support to baby size
- Color-changing plug signals water temperature
- Non-slip foam and contoured back wall
- Works in double sinks and full tubs
- Maximum weight not listed
- Some assembly required before first use
- Short limited warranty
- Color listed as white and gray in different places
Performance notes
Support comes from the bump on the tub floor and the angle of the contoured back, so how well a baby stays in place depends on setting the bump for their size. The drain plug changes color with water temperature, a quick visual check that works alongside testing the water by hand.
