If you've ever needed to do laundry late at night in Princeton and found every laundromat closed, you already know the gap this fills. Laundromat of Princeton is the only 24-hour laundromat in Princeton, NJ — open around the clock, every day of the year.
More people than you'd expect. In a college town like Princeton, 24-hour access isn't a luxury — it's a necessity for a lot of people.
Students who get home from studying at 11 PM and realize they have nothing clean for tomorrow
Healthcare workers and first responders coming off overnight shifts
Parents of young children who can't do laundry when the kids are awake
People who prefer the laundromat when it's quiet and uncrowded — typically after 9 PM or before 7 AM
Anyone whose work schedule doesn't fit into standard business hours
During daytime and evening hours (roughly 8 AM to 9 PM), there's an attendant on site to help with machines, handle wash & fold orders, and maintain the facility.
After hours, the facility is self-service but monitored. The machines work exactly the same way — card payment, same prices, same reliability. The wash & fold drop-off counter is not staffed during off-hours, but self-service laundry is fully available 24/7.
Our machines are brand-new, high-efficiency commercial washers and dryers. The coin-free card payment system means you just tap your debit or credit card at the machine. No scrambling for quarters at midnight.
We have machines in multiple sizes, including large 60lb capacity washers for comforters, sleeping bags, and bulky items.
Laundromat of Princeton is at 301 N Harrison St, Suite 22 in the Princeton Shopping Center. There's free parking directly in front. The shopping center is well-lit and accessible at all hours.
Yes. We are open 24 hours, 365 days a year. On major holidays, the laundromat remains open for self-service even if the attended wash & fold counter is closed.
The facility is in a well-lit shopping center with security lighting. We maintain the space for a safe, clean environment at all hours.
Wash & fold drop-off requires an attendant and is available during attended hours only. Check our website for current attended hours. Self-service laundry is always available 24/7.
