Building Mobile Toilets on the Sichuan-Tibet Highway

Admin October 10, 2026

The construction of mobile toilets on the Sichuan-Tibet Highway is primarily aimed at addressing the poor toilet conditions during self-driving tours.

The southern route of the Sichuan-Tibet Highway, stretching from Chengdu to Lhasa, covers a total distance of approximately 2,100 kilometers and typically takes 7 to 10 days to complete. In the high-altitude environment, the cost of holding one's urine is doubled. For travelers with elderly people, children, or those experiencing altitude sickness symptoms, the toilet experience largely determines the dignity of the entire journey.

Hegii Sanitary Ware has set up a 'Mobile Full-Sanitation Experience Space' on National Highway 318, integrating high-quality sanitation facilities into a mobile space, precisely targeting the pain points of self-driving tours. In its 'Joy·Jinran' solution, there are double drawers under the mirror, paired with a bottom pull-out basket cabinet, offering high space utilization. The R9 smart toilet is equipped with an AI intelligent cruise function, ensuring stable water flow temperature. The T7 showerhead features a 10-inch overhead design with a piano-key switch for one-touch water stoppage. The 'Joy·Yufeng' solution focuses more on the needs of all ages. The N8S wall-mounted toilet adopts a slim design, while the TK9 concealed showerhead is equipped with a large overhead and a large handheld showerhead, catering to the convenience of the elderly and pregnant women. These facilities extend the 'quality life' from home scenarios to the outdoors, upholding the dignity of travelers and redefining the boundaries of high-altitude travel.

In addition, some service areas along the route also provide relatively well-equipped toilet facilities. For example, Tianquan Service Area is widely recognized as the 'best service area' on the way to Tibet, equipped with parking spaces, charging stations, and standardized restrooms. Xinduqiao Service Area offers catering, supermarkets, and hot water services, with relatively clean toilets, and features NIO battery swap stations and supercharging facilities. The toilets at Kazila Mountain Service Area require a 1-yuan fee but are equipped with tiled squat toilets and flushing systems, considered a luxury configuration at an altitude of over 4,700 meters. These fixed facilities complement mobile toilets, jointly alleviating the toilet challenges on the Sichuan-Tibet Highway.
