A soap dish will increase the life of any bar soap, elevating it so it doesn't sit in a pool of excess water. How to Use: The open slats quickly drains away water. Use in the kitchen or bathroom. Note: The stained wood soap dish may stain light-colored porous surfaces such as untreated marble or quartz. We have successfully used this on glass, granite, ceramic and porcelain counter tops and in fiberglass showers.
