Walmart offers the Boon Naked Collapsible Baby Bathtub in Blue, model no. B610, for $37.16. (Amazon has it for the same price for Prime members.) Opt for in-store pickup to avoid the $4.97 shipping fee. That's the lowest price we could find by $23. It features a 1-piece design, slip-resistant base, rotating support brace, and can be configured in two different support positions.
