A lactation room is a private, dedicated space in a workplace where employees can pump breast milk. It is not a bathroom, not a breakroom, and not a storage closet with a chair in it. Under federal law, most U.S. employers are required to provide this space to nursing employees for up to one year after their child’s birth.
What a Lactation Room Actually Looks Like
At a minimum, a lactation room should have a lockable door, a comfortable chair, a flat surface for pumping equipment, and accessible electrical outlets. Many well-designed rooms also include a small sink for cleaning pump parts, a refrigerator or cooler for storing expressed milk, and a wastebasket. If multiple employees share the space, a privacy curtain between stations is standard.
Design guidelines from Washington University School of Medicine recommend going further: task lighting over the sink and work area, a thermostat so the room stays comfortable, and storage for cleaning supplies and paper towels. These aren’t luxuries. Pumping sessions typically last 15 to 30 minutes, and a cold, dimly lit room with nowhere to set anything down makes the process significantly harder.
Sound matters too. Breast pumps are noisy, and employees using the room generally don’t want coworkers hearing them through thin walls. Best practice calls for walls that extend to the ceiling structure above (not just to a drop ceiling), sound-dampening materials like fabric panels or carpeting, and solid doors. The ideal lock is an indicator deadbolt that displays “occupied” on the outside, so no one knocks or tries the handle mid-session.
Federal Law Requires More Than a Bathroom
The PUMP for Nursing Mothers Act, which expanded protections under the Fair Labor Standards Act, requires most employers to provide two things: reasonable break time for pumping and a space that meets specific standards. The space must be shielded from view, free from intrusion by coworkers or the public, functional for pumping, and available each time the employee needs it. The Department of Labor is explicit on one point: a bathroom does not qualify, period.
These protections apply for one year after the child’s birth and cover most salaried and hourly workers. Before the PUMP Act, only hourly (non-exempt) employees were covered. The expansion closed that gap, bringing protections to millions of additional workers. Employers who don’t comply can face enforcement action through the Department of Labor’s Wage and Hour Division.
Why Employers Benefit Too
Providing a lactation room isn’t just a legal obligation. Companies that support nursing employees see measurable returns. Breastfed babies tend to get sick less often, which means fewer days parents need to stay home with a sick child. That translates directly into lower absenteeism for both mothers and their partners. Research from the University of Arkansas for Medical Sciences found that employers who support breastfeeding in the workplace experience lower turnover and absenteeism rates, often at little cost.
The setup expense is genuinely modest. A private room with a chair, a table, an outlet, and a lock on the door covers the legal requirement. Adding a mini-fridge and a small sink improves the experience substantially without a major investment. For many workplaces, the room already exists. It just needs to be designated, furnished, and kept available.
Hygiene and Shared Spaces
If your workplace lactation room is shared among multiple employees, cleanliness becomes everyone’s responsibility. The CDC recommends wiping down pump dials, power switches, and countertops with disinfectant wipes before each use. After pumping, milk should be capped or sealed, labeled with the date and time, and placed in a refrigerator, freezer, or cooler bag with ice packs immediately.
If you’re using a shared pump (some workplaces provide hospital-grade pumps for communal use), cleaning the external surfaces after every session is especially important. Pump parts that touch milk are personal and should never be shared, but the motor unit and surrounding surfaces need regular disinfecting. Between pumping sessions during the same day, you can refrigerate your own pump parts in a sealed bag rather than washing them each time, though rinsing off milk residue first helps prevent buildup.
What a Lactation Room Is Not
A lactation room is not a wellness room, a nap room, or a multipurpose quiet space, though some workplaces try to combine these functions. The problem with shared-purpose rooms is availability. If someone is meditating in the room when a nursing employee needs to pump, that creates a real conflict. Breast milk production is time-sensitive. Missing or delaying a pumping session can cause pain, reduce milk supply over time, and increase the risk of infection. The room needs to be available when a nursing employee needs it, not when it happens to be free.
It’s also not a perk or a nice-to-have. The international standard, outlined in ILO Recommendation No. 191, calls for nursing facilities under adequate hygienic conditions at or near the workplace wherever practicable. In the U.S., federal law has moved well beyond “where practicable” to a clear mandate for most employers.
What to Do If Your Workplace Lacks One
If you’re returning to work after having a baby and your employer hasn’t set up a lactation space, you have legal standing to request one. Start with your HR department or direct supervisor and reference the PUMP Act by name. The request doesn’t need to be complicated: you need a private, non-bathroom space with a lock, a chair, a surface, and an outlet, available when you need to pump.
If your employer refuses or offers a bathroom as the designated space, you can file a complaint with the Department of Labor’s Wage and Hour Division. Retaliation for asserting your right to pump at work is also prohibited. Keep records of your requests and any responses in writing.
