Moving Toilet to Bedroom
Whether moving a toilet to a bedroom is illegal depends on the situation:

I. The upstairs resident privately moves the bathroom to the downstairs bedroom This situation generally constitutes illegal renovation behavior. According to Article 5 of the 'Measures for the Administration of Interior Decoration and Renovation of Residential Buildings (Revised in 2011)', interior decoration and renovation activities in residential buildings are prohibited from converting rooms or balconies without waterproof requirements into bathrooms or kitchens. Bedrooms themselves do not have waterproof requirements. When the upstairs resident privately moves the bathroom to the downstairs bedroom, it may damage the original building structure, increase the risk of water seepage, and thus affect the structural safety of the entire building. This behavior not only violates relevant regulations but may also have a serious impact on the lives of the downstairs residents. The downstairs residents have the right to request that the upstairs resident stop the infringement, restore the original state, and compensate for losses.
II. Renovation within a fully-owned residential property If the renovation is carried out within a residential property that is fully owned by the individual and does not violate the relevant management regulations of the residential community, such as ensuring proper handling of the building's structural safety, waterproofing, and drainage, then from a legal perspective, such a renovation within one's own space is generally not illegal. However, if it involves public areas or major alterations to the building structure that affect the safety of the entire building, it is illegal. Because the structural safety of a building is related to the stability and safety of the entire building, any structural alterations require professional assessment and approval.
III. Leased residential properties If it is a leased residential property and the tenant makes such alterations without the landlord's consent, it may also violate the lease agreement. The lease agreement usually clearly stipulates the tenant's usage methods and restrictions on the property. If the tenant makes alterations to the property structure or purpose without the landlord's consent, the landlord has the right to request restoration to the original state or claim compensation for losses.
