Why are most hotel pipe wells on one side of the corridor?

Reduce the impact on the interior of the guest room during maintenance. The built-in bathroom space becomes the transition space for the guest room to enter the home, which effectively reduces the noise and line-of-sight interference in the aisle. Moreover, the pipeline well can be arranged on one side of the corridor, which can reduce the influence on the interior of the guest room during maintenance and also play a role in sound insulation of the sleeping space of the guest room. Most hotels use this method.
