Portable Sink and Handwash Station Rental
Does Cal-OSHA Require Handwashing Stations on Construction Sites?
Compliance, hygiene, and hassle-free service.
Yes. Cal-OSHA Title 8, Section 1526 requires employers to provide handwashing facilities in close proximity to portable restrooms on construction sites. This isn’t optional — it’s a compliance requirement that Cal-OSHA inspectors check during site visits.
Our portable sink rentals satisfy this requirement. We place handwash stations adjacent to your portable restroom units for easy access and efficient service routing. Pair them with your porta potty rental and we deliver, service, and verify both on the same schedule.
General contractors, home builders, roofers, pavers, and landscapers across San Jose, Oakland, Santa Cruz, Watsonville, Salinas, and the greater Bay Area rely on our stations to keep their sites compliant without adding another vendor to manage.

How Many Units Does Your Site Need?
The general rule is one unit per 10 workers for a 40-hour work week. For sites with 20+ workers, or crews working overtime, add units accordingly. Cal-OSHA §1526 requires a minimum of one toilet per 20 employees. We’ll recommend the right count during your quote — just tell us your crew size and project duration.
For events, plan one unit per 50-75 guests for a 4-hour event. Add more for longer events, if alcohol is served, or if food is being served. VIP restroom trailers serve 75-150 guests depending on the model. Call us with your guest count and event details — we’ll quote the exact setup.
Yes. Standard weekly service works for most sites, but we offer twice-weekly and daily service for high-traffic crews. Multi-weekly service improves worker comfort, job site conditions, and crew morale. It’s a small investment that sets your site apart. We’ll help you determine the right frequency during the quote process.
We serve the Greater San Francisco Bay Area, Santa Cruz County, and Monterey County — including San Jose, Santa Cruz, Watsonville, Gilroy, Salinas, Monterey, and surrounding communities. View our full service area coverage.

What Is a Portable Handwashing Station?
A portable handwashing station is a self-contained unit with fresh water, soap dispensers, and paper towels that requires no plumbing connection — placed wherever workers or guests need hand hygiene access. Pro Portable Restrooms provides standalone portable sink rentals for construction sites and outdoor events across the Bay Area, Santa Cruz County, and Monterey County, meeting Cal-OSHA Title 8 §1526 requirements for handwashing facilities near portable restrooms on job sites.
Every handwash station is delivered fully stocked, serviced on a scheduled basis, and verified digitally through ServiceCore — the same accountability standard we bring to every rental.
Each unit includes:
- Fresh water tank (refilled at every service visit)
- Soap dispensers (restocked at every service visit)
- Paper towel dispensers
- Wastewater holding tank
- Foot-pump or hands-free operation
We carry multi-station configurations — two-station and four-station units — to match your site’s traffic and layout. Two-station sinks work well for smaller crews and intimate events. Four-station units handle high-traffic construction sites and large outdoor gatherings where multiple people need access simultaneously.

Do I Need Handwash Stations for My Outdoor Event?
Any outdoor event without permanent restroom facilities benefits from standalone handwashing stations. California health codes require handwash access near food service areas — if your event has food vendors, catering, or a food truck, portable sinks aren’t just courteous, they’re a health department expectation.
Beyond food service, handwash stations serve guest areas, staff zones, and volunteer stations. For weddings, festivals, corporate events, and community gatherings across the Bay Area, Santa Cruz, and Monterey Counties, we provide event-ready handwash stations that are clean, professional, and fully stocked for the duration of your event.
Need premium restroom facilities to match? Pair handwash stations with our VIP restroom trailers for a complete, high-end restroom experience.
How Often Are Portable Sinks Serviced?
Portable sinks are serviced on the same schedule as your portable restrooms — weekly is standard. For high-traffic sites with 20+ workers or events spanning multiple days, we offer twice-weekly and daily service to keep water fresh, soap stocked, and stations clean between heavy use periods. Upgrading service frequency is a small investment that keeps your crew washing their hands — not waiting in line at an empty station.
Every service visit includes:
- Fresh water refill
- Soap and paper towel restock
- Wastewater removal
- Exterior and basin cleaning
- Digital service verification through ServiceCore
Every visit is documented with a time-stamp and service record. You get proof of completion — not just a promise. For construction managers tracking compliance documentation or event coordinators managing vendor accountability, this changes how you evaluate your sanitation provider.
How Do I Choose the Right Handwash Station for My Site?
Choosing the right portable sink depends on three factors:
Site type: Construction sites need durable, high-capacity units that handle daily crew use. Events need clean, presentable stations that fit the occasion.
Traffic volume: A two-station unit serves a crew of 10–15 workers or an event of up to 75 guests. Four-station units handle larger crews and higher-traffic events. We’ll recommend the right configuration based on your expected usage.
Duration: Short-term event rentals and long-term construction site placements have different service needs. Monthly construction rentals include weekly service. Single-day or weekend event rentals include pre-event stocking and post-event pickup.

Can I Bundle Sinks With My Porta Potty Rental?
Most sites that need portable sinks also need portable restrooms — and often temporary fencing too. Order everything from one vendor and simplify your site services. One delivery, one service schedule, one invoice, one phone number to call.
Bundling with Pro Portable Restrooms means fewer vendors to manage, coordinated delivery and service timing, and a single point of contact when you need something adjusted. For contractors running multiple projects across the Bay Area, Santa Cruz, and Monterey Counties, that simplicity adds up.
