“Lapee gives women and people who need to pee squatting a quick, safe and hygienic way out.” Urinals for men have been around for a long time, but women and people who need to pee squatting have been long overlooked. For them the need to relieve themselves in public, at events or at festivals always comes with great difficulty. The lines for closed toilet cabins are always long and only two other options present themselves: going without peeing or finding an improvised and unsafe place to pee. Both are highly problematic and degrading. Lapee is a simple solution to a long standing example of gender inequality; Lapee gives women and people who need to pee squatting a quick, safe and hygienic way out. Lapee is pink and easy to spot. It can accommodate three users at a time. The curved walls offer privacy and protection while never feeling inclosed. The elevated position offers empowerment and makes it easy to oversee the nearby area. Lapee is a simple and sustainable choice in the sanitation industry. It is a very durable product with a long lifetime. It is made of recyclable materials and uses no water. Lapee is also stackable, in order to save carbon emissions from transportation. Lapee is touch-free. Due to it’s open structure, Lapee is auto-ventilated and extremely easy to clean which makes it the right choice for public spaces and outdoor events.
