Kubikids is an inflatable, square bath tub for children. It works by placing it in the shower stall, and then filling it with air, water and children, in that order. It’s not uncommon for our tiny Dutch apartments to lack a bathtub, in which case this device could add a luxury to an otherwise cramped place for at least part of the family.
Plus, anything that makes it look like you are cooking children just looks nice, but maybe that’s just me.
