Bathtub recommendation: Boon vs Angelcare vs Skip Hop
We have the Boon Soak and really like it for our small bathroom. It fits nicely in our double sink. The only downside is the drain plug doesn’t fully drain, so water pools in the bottom. Still, the newborn insert is great for our 2-month-old.

Looking for baby bathtub recommendations for small space
I got the Boon Soak because it fits in my kitchen sink (I have a double sink). It’s compact and the adjustable bump is handy. My baby is 5 months and still fits, but I can tell he’ll outgrow it soon. I considered the Angelcare and Stokke, but the Boon was the best sink fit.

First time mom needing advice on best baby bathtub
I love the Boon Soak’s contoured back and non-slip foam. My newborn doesn’t slide at all. The color-changing drain plug is a gimmick—mine never changed color. Also, like others said, it doesn’t drain completely. But overall I’m happy with the safety and comfort.

Baby bathtubs help
The Boon Soak’s foam backrest gets moldy if not dried out completely between baths. I remove the infant insert and let it air dry. It’s a bit annoying, but the tub itself is sturdy and baby seems comfortable. Wouldn’t use it without the insert for a newborn.

Infant bath - moderately granola moms
I picked the Boon Soak because it’s BPA/PVC/phthalate free and fits our double sink. It’s smaller than expected, but that’s fine for our tiny apartment. I wish the foam was removable or easier to clean, but I just wipe it down. We use it in the sink to save our backs.

Safe newborn/infant tubs
We got the Boon Soak because of the non-slip back and the infant support. It’s safe for our 3-week-old. But I’ve read that by 6-8 months, babies outgrow it when they can sit up. I’m not sure I’d buy it again for the price, but it’s perfect for the newborn stage.
