How Do Climbers Go to the Bathroom on Everest? Toilets, Waste Bags and Hygiene Explained

How do climbers go to the bathroom on Everest?

It’s quite an interesting question that every climber will ask before planning for the expedition, or those who are dreaming about reaching the world’s highest peak, Mount Everest. Doing bathroom is a human basic need, but it becomes so challenging in high altitude, as there are no luxury toilets, no running water, and certainly no privacy for disposing of human waste.

Also, the extreme cold temperature and lack of oxygen above Camp 1 take a long time to decompose human waste, no matter whether it is urine or feces. For decades, Everest climbers have been passing their human waste haphazardly on the trail, and this has resulted in the accumulation of frozen human waste.

This factor is directly polluting the glaciers, snowfields, and downstream water sources, most importantly impacting the area around South Col (Camp IV) and contaminating water in settlements like Gorak Shep and Lobuche. Due to this, Nepal Government made new regulation for Everest Climbing for stricter waste management.

One of the rule is to bring 8 Kg garbage back those who ascends beyond Everest Base Camp. Let’s dive more deeper into Nepal Government new law made with Sagarmatha Pollution Control Committee (SPCC) regarding the waste management in Everest.

Nepal Government New Rules For Pollution Control

Nepal Government and Sagarmatha Pollution Control Committee (SPCC) made strict rules and regulation to control pollution in the Everest Climbing route, and they are:

• Compulsory bring back at least two kilograms of garbage from Camp II, Camp III, camp IV each per climber.
• Climbers are required to deposit eight kilograms of garbage at Everest Base Camp after their expeditions.

• Mandatory use of poop bags and portable barrels.
• If climbers do not fulfill the above three mentioned rules, they wont get Garbage Clearance Letter and your deposited $4,000 (£2964) will not be returned.

Common Type of Toilet systems in Base Camp

Barrel Toilet

This type of toilet is widely used in the base camp where human waste is collected inside liners or bags and then later disposed.

Portable Cabin or Box Toilets

This type of Everest toilets system is mostly used by large support teams and it has rigid lightweight units.

Deep Pit

This is the most traditional type of toilet system where a whole is dug into moraine or in ground under a wooden platform.

How do Climber Go to the Bathroom on Everest?

The Most Comfortable Option in Everest Base Camp(5,364m)

At Everest Base Camp, climbers will stay for multiple week to adapt themself and to practice for the expedition. There, they have the closest thing to a normal toilet and dispose their waste in:

• Barrel toilets inside tents
• Waste collected in liners
• Regular cleaning by support staff

These systems are relatively organized compared to higher camps like Camp III or IV. Waste is later transported down the mountain for proper disposal. So at this level, how do climbers go to the bathroom on Everest answers comfortably in comparison to the what they faces next.

Camp I (6,061 m) and Camp II(6,400 m)

As climbers move higher than Everest Base Camp,  things become more basic as they have to dispose waste on:

• Simple toilet made nearby tents
• Buckets or barrels lined with bags
• At last, they seal everything and packed them and later carried down

Here, how do climbers go to the bathroom on Everest starts to get more challenging. Privacy decreases, and hygiene becomes harder to maintain. Still, these systems help reduce environmental damage by containing waste.

Camp III(7,200 m)

At this point, how do climbers go to the bathroom on Everest answers carefully, quickly, and often inside a tent. When climbers reach Camp III, they have to face extreme conditions as they have to do poop in wag bags inside the tent and behind the rocks only if they found any.

Due to less space, strong wind, and most importantly freezing cold, building a proper toilet using tent is not possible. So, they pass their human waste like pee and stool carefully and quickly.

Camp IV(8,000 m)

Camp IV also known as the death zone, where how do climbers go to the bathroom on Everest becomes extreme. As it has no toilets, so climber use wags bags and pee bottles. Also, to avoid peeing and feces, climbers often focus on avoiding heavy meals.

Wag Bags

A major part of understanding how do climbers go to the bathroom on Everest is the use of WAG bags. Wag bag or Waste alleviation and gelling bags is a special sealed bag which has high absorption capacity with solidfying agents. Climbers use these bag to do stool inside the tent and pack it and carry them down with themself. Wag bag is also known as poop bags and they are:

• Leak-proof bags with super-absorbent polymers (SAP)
• Designed in such a way they reduce odor

New regulations now require Everest climbers to carry their waste down the mountain due to pollution concerns. This system is critical because waste does not decompose in freezing conditions.

Pee Bottle or Pee Funnel

The pee bottle have wide mouth which is used to urinate both male and female climbers. Urine Funnel is used by women to pass urine inside down suits.

The pee funnel helps climbers to urinate while standing no matter their gender. It also avoid you to pull down your pant in the freezing temperature during night and in summit hour.

Summit Push

During summit Push, climber avoid eating heavy and carry pee bottle and funnel to pass urine. Similarly, they also carry wags bags in case of emergency. So, how do climbers go to the bathroom on Everest during summit day? Most climbers try not to go, as they plan their solid intake to avoid needing to go.
