Fisher Price 4-in-1 Sling N Seat Baby Bath Tub

This was a useless purchase. The quality of the tub is absolutely fine, no issue at all with it in that regard. But honestly we only used it when she was a newborn and haven't used it since because the cut outs don't fit my sink. So I just get in the tub with her, or now that she's 10 months she just sits by herself in the tub and plays. I feel bad asking for this as a gift.
I'm considering taking it outside and filling it with water as a summer cool off method for her.
