Typical Weekly Range
The $150 to $275 weekly range covers a combined sink-toilet unit. Short event windows tend toward the high end because delivery, servicing, and pickup are compressed.

How Much Is a Porta Potty With a Sink?
A porta potty with a sink in the Phoenix area typically costs $150 to $275 per week; Phoenix Portable Bathrooms bases each quote on unit type, rental length, and required service stops across the Valley. Knowing what the rate includes makes it easier to compare a combined unit with a standalone handwashing station or a restroom trailer.
Quick Summary
- A combined sink-toilet unit typically costs $150 to $275 per week in the Phoenix market.
- Long-term construction placement runs about $600 to $1,200+ per month, and contracts of 30 days or more can lower the average weekly cost.
- A standalone handwashing station costs $40 to $90 per week when toilets are already on-site.
- ADA-compliant sink units run $200 to $325 per week, while restroom trailers start at $500+ per day.
Three Things Behind the Price
Sink Hardware and Service
The added cost covers a fresh water tank that usually holds 5 to 7 gallons, a soap dispenser, and a foot-pump or hand-crank faucet, plus refilling and sanitizing at each service visit.
What to Review in a Quote
Confirm the unit grade, rental dates, delivery and pickup, service frequency, site access, and freshwater refill before comparing totals.

Inside a Combined Sink-Toilet Unit
The sink basin beside the toilet, with the fresh water reservoir, soap dispenser, and foot-operated or hand-crank faucet visible. This explains why one footprint still requires service on both the waste and freshwater sides.
Combined Unit vs. Standalone Handwashing Station
The one-piece unit next to a standard toilet paired with a separate sink station. The comparison clarifies the footprint and flexibility of each setup.
Restroom Trailer Sink and Interior Features
Running-water sinks, mirrors, interior lighting, and climate control. Those features matter for weddings and corporate events, especially when Phoenix temperatures push past 110 degrees.
Rental Option Snapshot
Standard Toilet Without a Sink
$100 to $150 per week suits straightforward construction placement when separate handwashing access is available.
Standalone Handwashing Station
$40 to $90 per week adds sink capacity without replacing an existing toilet fleet and can support site planning around Arizona Department of Environmental Quality and OSHA sanitation expectations.
Combined Sink-Toilet Unit
$150 to $275 per week is the practical middle ground for events, retail sites, schools, and job sites that need both functions in one footprint.
ADA and Trailer Options
ADA-compliant sink units cost $200 to $325 per week and use a wider door, interior turning space, and lower sink basin under the 2010 ADA Standards for Accessible Design. A basic 2-stall trailer with sinks may run $400 to $600 per day, while smaller luxury trailers start around $500 to $900 per day and larger feature-rich setups can reach four figures per day.

| Rental Option | Typical Rate | Best Fit |

What the Extra Cost Covers
A combined unit generally costs roughly 20 to 40 percent more than a toilet-only unit at the same grade, or about $20 to $40 more per week, because the route crew services both the waste tank and the freshwater side. The base rental includes the unit, delivery, one setup, and standard service intervals; the sink adds tank, pump, refill, and sanitizing work.
Factors That Change the Price
Rates shift with daily, weekly, or monthly duration; standard, deluxe, ADA, or trailer grade; and the number of service visits. High-rise delivery, gated sites, remote desert lots, multi-day festivals, and job corridors near Loop 202 can add route time, while larger water and waste tanks may reduce visits but cost more to service. Outdoor events lasting more than one day may need more frequent servicing, especially at unshaded venues such as South Mountain Park.
Common Follow-Up Questions
If toilets are already on-site, a separate sink station is usually the flexible add-on; when space and delivery simplicity matter, use the combined unit. For a multi-hour event, a useful starting point is one stall per 50 to 75 guests, then adjust for event length and service needs. Public events on City of Phoenix property typically need at least one ADA unit per bank of standard toilets. Wedding trailers are best reserved at least a few weeks ahead during the Valley's busy October-through-April outdoor season.
