External Movement of the Dry Area in Small-sized Toilets

The external movement of the dry area in small-sized toilets requires space surveying, location selection, functional planning, and construction optimization to enhance both functionality and aesthetics. The specific plan is as follows:

I. Determining Applicable Scenarios

One of the following conditions must be met:

1. Limited Space: The original toilet has an imbalanced distribution between the dry and wet areas, causing interference among washing, toileting, and showering functions. For example, if the dry area is less than 0.8 square meters, the distance between the sink and the toilet may be too close.
2. Layout Defects: The dry area is located inside the wet area, requiring passage through the shower area for washing, which introduces moisture and compromises privacy, such as in a 'linear' layout without an independent door partition.
3. Upgraded Needs: There is a need to add a children's washing station, a makeup area, or space for appliances, which the original dry area cannot accommodate, such as increased family members leading to conflicts during peak usage times in the morning and evening.

II. Core Implementation Steps

1. Space Surveying and Needs Assessment

   • Precise Measurement: Record the dimensions (length, width, height) of the original toilet's dry area, the waterproofing range of the wet area (the shower area should extend to the wall at 1.8 meters), the location of drainage pipes (such as the distance from the floor drain to the wall), and the width of the doorway (which should be at least 0.7 meters to ensure the sink can be moved in).
   • Needs Analysis: Clarify the usage habits of family members (such as whether simultaneous washing by two people is needed), functional priorities (such as reserving 0.6 meters of width for a makeup table), and style preferences (such as recommending blue walls with white tiles for a fresh and clean look).

2. Selecting the External Movement Location

   • Corridor Area: Prioritize corridors with a width of at least 1.2 meters and without load-bearing walls or high-voltage power lines. Expand the space by removing non-load-bearing walls (with confirmation from the property management), minimizing damage to the original toilet.
   • Adjacent Unused Space: Such as storage rooms or balcony corners, ensuring that the drainage pipes can connect to the original drainage system (with a slope of at least 1%) to prevent odors.
   • Internal Adjustment of the Toilet: Reduce the waterproofing range of the original wet area and move the dry area to an unused space inside the doorway (such as the area above the original toilet), requiring re-planning of the toilet and shower area layout.

3. Optimizing Functional Layout

   • Sink Design: For use by two people, a double sink with a length of at least 1.2 meters and a spacing of at least 0.4 meters between sinks is needed; for makeup needs, a mirror with a mirrored cabinet (depth ≤ 0.3 meters) and open shelves can be configured for easy access to items.
   • Appliance Integration: Reserve an inlet, an outlet, and a socket of at least 10A for the washing machine; the dryer requires a 16A socket, and stacking is recommended to save space.
   • Storage Details: Leave 30 centimeters under the bathroom cabinet for a laundry basket and a robot vacuum cleaner; use wall-mounted drainage pipes to avoid dead corners; a combination of a mirrored cabinet, open shelves, and a tall cabinet can hide toiletries.

4. Dry-Wet Separation and Partition Design

   • Material Selection: Use glass bricks (translucent but opaque), frosted sliding doors (with strong privacy), or long-hole glass (aesthetically pleasing and transparent) to separate the wet and dry areas; long-hole glass partitions are recommended between the shower area and the toilet.
   • Style Matching: A fresh and clean look suits blue walls with terrazzo floor tiles; a sweet Nordic style can choose light pink walls with Nordic patterned tiles.

III. Key Construction Considerations

1. Drainage System: Pre-embed drainage risers in advance to avoid wall demolition and hole drilling later; the ground in the external movement area should have a slope (≥ 2%) towards the floor drain.
2. Waterproofing Treatment: Apply waterproof coating to the ground and walls (from directly below the sink to the wall at 1.5 meters) in the external movement area, and install a 'water stop strip' under the threshold stone to prevent water seepage.
3. Material Selection: Prefer glazed tiles for walls (water-resistant and easy to clean), wooden flooring for the dry area of the ground (which should be separated from the wet area by a threshold stone to block moisture), and anti-slip tiles for the wet area.
4. Countertop Protection: Install a water baffle (height ≥ 5 centimeters) to prevent water from seeping into the wall, and seal the joint between the sink and the wall with glass glue.

Through scientific planning and attention to detail, the external movement of the dry area in small-sized toilets can significantly improve usage efficiency and spatial aesthetics while reducing the risk of bacterial growth.
