Abstract: A bath trainer is provided defined by a bucket having sides forming an interior water-tight space for holding water, said sides being configured to fold to a closed position when the bucket is not in use and unfold to an open position for receiving water; and a mat configured to be removably attached to said bucket. While the bucket is closed, other elements may be stored therein, such as a mug for pouring water and rising, a stool, bathing toys, etc. At least some portion of the bucket is made of a thermochromatic material that changes color with temperature so that a user can determine whether the water within the bucket is at an appropriate temperature for a child to take a bath.
