What are the washroom / toilet facilities during trek?

On campsites, our team will dig dry pits and assemble a toilet tent to provide for safe and secure quarters. A shovel will be provided within the toilet tent as well. Using water in the toilet tent is restricted; you will need to carry your own toilet paper. On the more difficult expeditions, toilet tents are not carried to the higher camps (above base camp) due to restriction of space (to pitch the tent).
