Bath day shouldn't wear you both out.
The walk to the bathroom. The cold tiles. Gripping the rail. For a lot of families, bath day is the hardest part of the week, so it gets pushed back, again and again.
These sponges let you give a full wash right where someone's comfortable: in their chair, on the edge of the bed, under a warm blanket. No tub, no basin, no struggle. About ten minutes, start to finish.
