Square, water-resistant vinyl portable shampoo basin with air pump - Included: Air pump - Shape: Square portable shampoo basin - Material: Water-resistant vinyl Thank you for viewing. I've used it a few times. When you buy it online, it comes with a portable shower, a waterproof sheet, and a waterproof apron, but they weren't very convenient, so I got rid of them. Instead, there's an air pump. It's essential.
