These round wooden trays are great for use with our ShowerTime Rocks. Place 1 Rock on the tray to allow the water to drain through, extending the life of the rock. Rocks can be used for approximately 2 ten minute showers if they are removed from the shower floor and allowed to air dry. Makes a great gift, especially when combined with a ShowerTime Rock. The price is for one round wooden tray. Diameter: 3.75" Height: 1.2" Each tray is individually packaged in a clear wrapper.
