Prefabricated Slab House with Toilet Door

When adding a toilet door in a prefabricated slab house, it is necessary to comprehensively consider the structural characteristics of the house and the usage requirements of the bathroom. The following are the specific key points:

I. Impact of Wall Structure on the Toilet Door

When adding a bathroom to a prefabricated slab house, the walls should be made of lightweight materials (such as aerated concrete blocks, light steel keel gypsum boards, etc.), and it is recommended that the thickness does not exceed 120 millimeters. This requirement directly affects the installation method of the toilet door:

• Door Frame Fixing: Lightweight walls have limited load-bearing capacity. The door frame should be fixed to the wall keels or blocks using expansion bolts or special anchors to avoid directly damaging the prefabricated slab structure. If the wall is of a light steel keel structure, additional reinforcing keels should be installed at the door frame position to improve stability.
• Door Opening Size: The width of the door opening should be adjusted according to the wall thickness to ensure that the door leaf can open without conflicting with surrounding facilities (such as toilets and washbasins). For example, the standard door opening width for a 120-millimeter-thick wall is usually 700-800 millimeters.

II. Waterproofing and Moisture Resistance Requirements

The bathroom environment is humid, so the toilet door needs to have moisture-resistant properties, and the connection between the door frame and the wall should be the focus of waterproofing treatment:

• Door Material Selection: It is advisable to choose PVC-laminated doors, aluminum alloy doors, or solid wood composite doors (with waterproof paint treatment on the surface). Avoid using solid wood doors (which are prone to deformation) or untreated density board doors.
• Waterproofing Details: A metal or plastic moisture-proof strip should be installed at the bottom of the door frame to prevent moisture from seeping in from the ground. The contact area between the door casing and the wall should be sealed with glass glue to prevent moisture from entering the interior of the lightweight wall along the gaps.

III. Balancing Ventilation and Privacy

The bathroom needs to balance ventilation and privacy, and the design of the toilet door should meet the following conditions:

• Ventilation Design: If the bathroom has no independent windows, a toilet door with louvers or frosted glass can be selected to enhance air circulation. If a solid door is used, an exhaust fan should be installed above the door or linked to the exhaust system.
• Privacy Protection: For glass doors, opaque materials such as frosted glass or fluted glass should be chosen to prevent privacy leakage caused by transparent glass. Solid doors can be equipped with door locks (such as bathroom-specific locks) to improve security.

IV. Installation Precautions

• Level Calibration: Before installation, check whether the door opening is level to avoid problems such as the door leaf not closing properly or friction noise due to an uneven wall.
• Hardware Selection: Hinges should be made of stainless steel to prevent rust. For door locks, it is recommended to choose models with a moisture-resistant coating to extend their service life.
• Coordination with Overall Decoration: The color and material of the toilet door should be unified with the style of the bathroom tiles and sanitary ware to enhance the overall aesthetics.
