Wet Laboratory space types are defined as laboratories where chemicals, drugs, or other material or biological matter are tested and analyzed requiring water, direct ventilation, and specialized piped utilities. Wet Laboratory space types do not include biohazards in Levels BL-2, BL-3, and BL-4 as defined by the 2007 NIH/CDC guideline "Biosafety in Microbiological and Biomedical Laboratories (BMBL) 5th Edition,". The Wet Laboratory space types are typically located within a building specifically designed to house them (see WBDG Research Facilities.
Wet Laboratory space types are unique in that they must accommodate simultaneous and separate ventilation and utility connections at individual lab modules to ensure both the reliability and accuracy of results as well as occupant safety throughout the space. Typical features of wet laboratory space types include the list of applicable design objectives elements as outlined below. For a complete list and definitions of the design objectives within the context of whole building design, click on the titles below.
- Surfaces: Resilient surfaces are an integral part of the Wet Laboratory space type design. Use epoxy paint for lab walls and monolithic, seamless, chemical-resistant vinyl flooring with integral coved based and mylar finish.
- Fume Hoods: Design Wet Laboratory space types to accommodate one 6'-0" chemical fume hood for each laboratory module, and provide direct 100% exhaust. It is also typical of this space type to include an acid and corrosives vented storage cabinet located under the fume hood, as well storage for emergency equipment.
- Laboratory Occupancy: Occupancy Group Classification for Wet Laboratory is B2, Sprinkler protected construction, as per IBC, with a GSA Acoustical Class C1 for enclosed spaces and Class C2 for open spaces.
- Fire and Life Safety: All Laboratory spaces should contain a hand-held chemical emergency fire extinguisher in an emergency equipment cabinet. There is generally one fire alarm pull station by each egress point and an audible and visible (strobe) alarm in each occupiable space (not including closets, storage rooms, or coat racks). Also include toxic gas monitors in each lab module and a gas storage area with audio and visual (strobe) alarms both inside and outside the lab. Eyewash and deluge shower should be located at each module quad. For more information, see WBDG Security and Safety in Laboratories.

The following program is representative of Wet Laboratory space types.
- The planning module fits within a 24' by 32' column bay, which allows two modules to be joined to form a 24' by 24' lab suite.
