A portable sink rental in San Rafael runs on a self-contained fresh and gray water tank, no plumbing hookup needed, and most standard units carry a 60 to 70 gallon holding tank. That's enough for a full day of hand washing or hair rinsing on a job site, at a wedding, or parked next to your portable restroom rental setup.
A portable sink station is a standalone basin with its own fresh water tank feeding the faucet, and a separate tank underneath catching the gray water runoff. No sewer line, no garden hose required, just fill the fresh tank and go. Most units pair a foot pump or a battery-powered faucet with soap and towel dispensers built into the frame, which matters because 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at any washing facility, not just sanitizer. San Rafael crews running framing or demo jobs usually pair one handwashing station rental per crew cluster near the standard porta potty rental units rather than one sink per worker. If you're staging a hair-washing station for a film shoot or a shelter intake, ask about hot water portable sink options, since some units run a small heater off the same water tank instead of straight cold fill. That's the difference between a basic hand rinse and something people can actually wash hair in comfortably.
Hair washing needs more water flow and warmer temperature than a quick hand rinse, so a portable sink for hair typically pairs a larger fresh water tank with a heating element or an insulated line. Camping portable sink setups usually run smaller, just a basin and a gravity-fed tank, good for rinsing dishes and hands at a group site. Either way, the same 60 to 70 gallon tank spec applies to most rental frames, which is why we size the water tank to expected headcount rather than guessing. A crew of 15 near downtown San Rafael pulling long shifts on a renovation will drain a small tank fast, so we often deliver a second portable sink station alongside a porta john rental to keep both washing and toilet demand covered. For weekend camping trips or reunions out past San Anselmo, 4.3 miles west, or Larkspur, 5.1 miles southwest, we've delivered combined sink and toilet packages that cover a full weekend without a refill.
OSHA 1926.51(c) sets toilet ratios for construction sites, one facility for 20 workers or fewer, stepping up as headcount grows, and while that standard covers toilets specifically, most job sites budget one handwash station for every one or two toilet units to keep pace. A crew running under construction site services in San Rafael with 20 workers on-site typically pairs two to three sinks with their toilet count, especially if the scope involves painting, coatings, or pesticide work, since OSHA 1926.51(f)(1) requires washing facilities specifically where employees apply paints, coatings, herbicides or insecticides. Event planners sizing restrooms for a wedding or festival should check our how many porta potties do I need guide, since sink counts generally follow the same per-head math. If you're mixing ADA units into the layout, remember ADA Standards section 213.2 requires at least 5 percent of clustered single-user toilets to be accessible, and the same logic applies to sink placement, keep one within reach of the ADA accessible porta potty unit.
Pricing depends on tank size, whether you need hot water, and rental length. Here's what a standard unit runs against comparable equipment we deliver in San Rafael:
| unit | duration | low | typical | high |
|---|---|---|---|---|
| standard | day | 100 | 150 | 350 |
| standard | week | 130 | 200 | 500 |
| standard | month | 125 | 200 | 325 |
| delivery_fee | day | 100 | 150 | 500 |
Delivery fees usually apply once per drop, not per unit, so a multi-sink order to one San Rafael address often costs less per station than a single unit delivered alone. For a deeper breakdown of daily versus monthly math, see porta potty rental cost and monthly porta potty rental, since sink pricing tends to track the same curve as toilet rental. If your event or job runs long, ask about combining a sink order with a temporary fence rental or light tower rental delivery to share the trip.
No. Every unit carries its own fresh water tank and a separate gray water tank underneath, so there's no need for a spigot or hose bib nearby. We fill the tank before delivery and can schedule a refill visit if your event runs past a few days. This is the same reason camping porta potty rentals work at sites with zero utilities.
Yes, some units include a small heating element built into the fresh water tank, good for hair washing stations, shelter intake lines, or cold-weather job sites. Not every unit ships heated by default, so flag it when you request a quote. Ask about pairing it with a shower trailer rental if you need full-body washing too.
It depends on headcount and use, but a standard 60 to 70 gallon tank on moderate use covers a full workday for a mid-size crew before it needs a refill or swap. High-use hair washing stations or large events may need a same-day refill visit. We schedule refills the same way we handle service intervals on septic pumping service calls, based on actual demand.
OSHA doesn't mandate a sink for every toilet, but 1926.51(f)(1) requires washing facilities specifically after paint, coating, herbicide or insecticide work, and general practice pairs sinks with toilets anyway. Check our OSHA portable toilet requirements page or handwashing requirements guide for the full breakdown before you finalize headcount.
Yes, weekend rentals are common for weddings, festivals, and family gatherings. Pricing runs as a short-term rate rather than the daily or weekly table above, so ask for a weekend quote directly through request a quote or check event restroom rental for bundled options with toilets included.
