Draininfloor

Draininfloor refers to a drainage element installed flush with or recessed into the floor to collect surface water or wastewater and route it to the building drainage system. It is used in bathrooms, showers, laundry rooms, basements, and other wet areas where water may pool. Drain in floor can be a point drain with a circular grate or a linear drain spanning the floor.

There are two primary formats: point drains (round or square outlets) and linear/trench drains (elongated channels). Point drains are discrete, often with removable baskets or grates; linear drains provide continuous drainage along a wall or threshold. Grate materials are typically stainless steel or engineered plastics. Some systems include integrated shower bases or waterproofing membranes to simplify installation and reduce tile height differences.

Effective in-floor drainage requires proper slope toward the drain, typically 1 to 2 percent, a waterproofing membrane beneath tiles, and correct trap height to maintain a water seal. Venting and access for cleaning are important. In wet rooms, drains may be paired with curbless or low-threshold designs and must be sealed against leaks.

Materials include stainless steel, brass, or plastic grates with polymer bodies. Traps help prevent sewer gas but require periodic cleaning to avoid clogging. Debris and hair are common causes of reduced flow, so regular cleaning of the grate and surrounding area is recommended.

Installation should comply with local plumbing codes and moisture-control standards. Consider slip resistance for floor surfaces, proper sealing to prevent leaks, and adequate access for maintenance.
