Greatest invention, ever.
Well, only if you love soaking in the tub.
You attach this little plastic gadget (it has little suction cups) over the drain on your tub. It basically covers the lower overflow drain and makes a new higher drain hole at the top of the gadget allowing you to add more water to the tub. I don’t know about you but when I fill the tub and then get in my body weight raises the water level, (something we learned in science class but I never thought it would apply to me until I started taking baths). Then, due to the raised water level, a lot of that water just goes out of the overflow drain. This is why this gadget is so fabulous. Soak long, soak deep. You gotta get one!
