Cool Home Silicone Soap Dish Holder with Self-draining Slopes, Pack of 4, Multi-color Great for soap, works for sponges, may be a little smaller for an average sponge. Size: 4.5"x3.1"x0.4" Self-draining slopes allow water to flow out. It makes the bar of soap last longer because the water drains off it quickly The soap bar dries and leaves no gunky mess, and the sponge dries without sitting on the counter top It will never rust or get mouldy, not stick too tightly with your soap No slippage of the soap and no soggy sponge. Both soap bar and sponge will feel happy with this dish. lol
