Toilet Door Integrated into Wardrobe

Integrating the toilet door into a wardrobe is a renovation design that hides the bathroom entrance within the wardrobe, achieving spatial integration and visual concealment through a double-door structure, suitable for optimizing small living spaces.

I. Spatial Structure and Functional Adaptation

1. Double-Door Design
   The bathroom and wardrobe are separate spaces, with the corridor partially overlapping to create a structure where the "wardrobe door conceals the bathroom door." In some cases, the back panel of the wardrobe serves directly as the bathroom wall, with custom cabinet doors covering the entrance, presenting a flat cabinet appearance and avoiding the visual fragmentation caused by traditional bathroom doors in the bedroom.
2. Small Apartment Optimization
   Common in apartments ranging from 30-70㎡, integrating the bathroom and wardrobe spaces can save 3-5㎡ of usable area. The bathroom is typically configured to a 0.5-bath standard (toilet + sink), with a few cases including a shower area, requiring the choice between a bright bathroom (with a window) or a dark bathroom design based on the layout.

II. Technical Considerations

1. Moisture-Proofing
   Both the interior and exterior of the wardrobe should be painted with waterproof paint, the bathroom floor should have a waterproof layer, and sealing strips should be installed in cabinet gaps to prevent moisture penetration, which could lead to cabinet deformation or mold.
2. Ventilation Design
   Equipped with an exhaust fan or a small ventilation system, some cases optimize air circulation through an L-shaped corridor to prevent odors caused by insufficient ventilation in dark bathrooms.
3. Hardware Requirements
   Heavy-duty hinges and door hinges are required, with a recommendation for magnetic, handle-free designs to reduce mechanical wear and maintain the overall appearance of the cabinet.

III. Design Motivations and Derived Functions

1. Privacy and Space Protection
   Addresses privacy and moisture issues when the bathroom door faces the bed directly, while avoiding the disruption of bedroom space integrity caused by traditional layouts, enhancing living comfort.
2. Functional Expansion
   Some cases utilize the corridor between the wardrobe and bathroom to create a mini dressing area or storage space, further exploring the potential of small apartments.

IV. Precautions

This design requires strict control over key aspects such as moisture-proofing, ventilation, and hardware quality, especially in dark bathroom cases where ventilation system design should be strengthened. If the bathroom includes a shower area, additional waterproofing measures are necessary to prevent long-term moisture damage to the cabinets.
