Movement of Toilet and Sink

The movement of toilets and sinks can be achieved primarily through two methods: moving the sink outside the bathroom and using mobile toilets. Here are the specific designs and considerations:

I. Moving the Sink Outside the Bathroom

Relocating the sink from inside the bathroom to an external area can achieve dry-wet separation and enhance space utilization. Common designs include:

1. Low Wall Partition
   Construct a low wall slightly taller than the sink (typically 80-100cm in height) between the sink and the corridor, with the top suitable for placing green plants or decorations. This design can block water splashes while maintaining space transparency, suitable for small bathroom layouts.

2. Screen Partition
   Use glass, metal, or wooden screens as later-added partitions. Glass screens offer strong light transmission, suitable for areas with insufficient lighting; wooden screens can create a warm atmosphere but require moisture-proof treatment.

3. Wall Partitioning
   Build a wall from the side of the sink to the ceiling, forming an independent washing area. This method is suitable for corridor areas with sufficient lighting and ample space, providing complete isolation from moisture but sacrificing some transparency.

4. Half-Wall Partition
   Construct a half-wall approximately 1.2 meters high on the side of the sink, with the top suitable for hiding water and electricity pipelines and the bottom reserved for storage space. This design balances functionality and aesthetics but requires the half-wall height to be higher than the splash range of the sink.

5. Entrance Hall Layout Reconstruction
   Move the sink to the entrance hall area, achieving a convenient layout for "washing hands upon entering" or "washing outside the bedroom." This method requires advance planning of drainage pipelines and ensures sufficient space in the entrance hall (recommended area ≥ 3㎡).

II. Mobile Toilets

Adopt environmentally friendly mobile public toilets made as a whole, equipped with a feces collection system, sink, smart mirror, and other facilities, which can be directly transported to the site for use. Double-unit mobile toilets combine imitation wood design with ceramic facilities, meeting the needs of multiple people using them simultaneously, suitable for temporary scenarios such as scenic spots and construction sites.

III. Design Considerations

1. Drainage System
   If the sink is adjacent to the bathroom with only one wall in between, the drainage pipe can be directly connected through the wall; if the sink is moved a long distance, ensure the drainage pipe slope is ≥1% (i.e., a drop of 1cm per meter) to avoid water accumulation and backflow.

2. Waterproofing Treatment
   After moving the sink outside, the floor should be coated with flexible waterproof paint (height ≥ 30cm), and the wall waterproof layer height should be ≥ 1.8 meters. If adjacent to a wooden floor area, a water-blocking stone or threshold stone should be installed.

3. Material Selection
   It is recommended to tile the walls (moisture-proof and easy to clean), and the floor can be consistent with the living room or use anti-slip tiles; if installing a wooden floor, a metal or stone partition should be installed around the sink.

4. Countertop Details
   Install a water-blocking strip (height ≥ 5cm) on the edge of the sink to prevent water from flowing to the floor or seeping into the wall. Recommended countertop materials are quartz stone or ceramic, avoiding natural stone materials that are prone to staining.
