Sims 3 Store Animals Abound Bath Set:
Rinse ‘n Roar bathtub
Savagely Silly Sink
Very Beary Towel Holder
Playground Potty (full size and toddler potty)
The Savagely Silly Sink with the Rinse ‘n Roar bathtub's feet as a toddler bathtub. I suggest placing it against the wall to prevent the mother from sitting behind it and reaching through the back of the tub.
This tub works the same as my Toddler Washtub.
