We have tried and tested many soap dishes, and this soap dish checks all the right boxes.
It's really important for a soap dish to allow water to drain freely, and to allow sufficient air flow to dry out your solid shampoo/conditioner/body soap in between uses, to extend the lifespan of the bars. We personally find that soap dishes with shallow grooves are not effective, and we end up with sticky and damp soap as the underside does not have an opportunity to dry out.
