24-Hour Laundromats in St Louis, MO

3 of the 45 laundromats we list in St Louis have 24-hour access.

Google's hours badge lumps every '24 hours' listing together, whether it means a staffed desk all night or just card-access machines after the attendant clocks out — a distinction map search can't show but matters if you're standing outside at 2 a.m. Every 24-hour laundromat here is confirmed from the shop's own posted hours or website, not a stale hours field.

Bring quarters even at a 24-hour spot. Card and app readers are common now, but the change machine is usually the first thing to break overnight with no attendant to fix it — cash-backup quarters keep you from getting stuck mid-cycle at 3 a.m.

Good to know

Are there laundromats open 24 hours near me?

Most mid-size and larger cities have at least a few, often chains or independent shops that advertise 24/7 self-service on their door and website. A typical overnight load runs $5-8 total: $2.50-$4.50 to wash and about $0.25 per 6-8 minutes to dry.

Is it safe to do laundry at a 24-hour laundromat at night?

Stick to locations with visible security cameras and good street lighting, which most chain-run 24-hour shops have since they're unattended overnight. If you're unsure about a specific location, call ahead and ask whether staff are on-site after a certain hour.
