We ended up removing the vinyl sun shade and nailing old hardwood planks to act as a roof because the original shade kept filling with rain or blowing off on one side during Thunder storms.. Also, If you live in a critter-infested area, always check the sand before allowing kids to play because this is not air tight. We often find frogs, lizards, spiders, etc. inside the box. Other than that, great kit, well made for the money.
