How far is Mercer Island from Seattle?
Mercer Island sits 8.9 miles southeast of Seattle across Lake Washington. The drive takes about 19 minutes over the I-90 floating bridge. Delivery fees to Mercer Island typically run higher than in Seattle proper because of that distance and the route constraints. Seattle Porta Pros charges delivery fees in the $100 to $150 range for weekly rentals and similar amounts for single-day drops. A weekend delivery may cost between $125 and $540 depending on what you're renting and when you need it. Check your exact address with us before booking so we can quote you accurately, because bridge access rules and residential street placement matter on the island.
Mercer Island is a residential community with strict codes around construction and temporary equipment. Any portable toilet, dumpster or storage container placed in the public right-of-way requires a Street Use permit issued by the Seattle Department of Transportation (SDOT). The permit process uses the ROW Management - Simple Review base fee, plus location and duration charges. You'll submit through the Seattle Services Portal and upload a Right-of-Way Impact Plan. Containers must sit in legal parking spaces, stay at least 30 feet from intersections, 10 feet from driveways and 15 feet from fire hydrants. We handle placement and removal; you'll need the permit before we deliver. Visit our porta potty permit requirements guide for more detail.
When you rent from Seattle Porta Pros for a construction site or home renovation on Mercer Island, we size your order to the job. OSHA 1926.51(c) requires 1 toilet facility for 20 workers or fewer, 1 toilet seat and 1 urinal per 40 workers from 21 up, and 1 toilet seat and 1 urinal per 50 workers at 200 or more. If your crew falls under 20 workers, one standard unit covers the rule. Larger sites need multiple units. A standard portable toilet measures about 44 by 48 inches on the ground and stands 92 inches tall, so it fits most driveways and staging areas. Our team discusses placement with you before delivery to avoid surprises.
What's included in a weekly rental?
One service visit per week is the baseline for up to 10 users over a 40-hour week, per ANSI/PSAI Z4.3 industry standards. That means we pump the tank, restock toilet paper and hand sanitizer, deodorize and do a quick clean each visit. Your cost falls in the $130 to $500 per week range for a standard unit depending on how many you need and how long you keep it. Deluxe flushable units cost more upfront but require less frequent servicing and appeal to clients on residential sites where appearance matters. If you need daily service instead, try our daily rental option for shorter jobs.
A standard unit's 60 to 70 gallon tank empties at one visit per week for typical use. If your crew or event draws more than 10 users in a week, add another unit instead of pushing service frequency higher. Two units at one visit per week cost less than one unit with multiple visits. If you're running a weekend event on Mercer Island and expect 20 to 50 guests, rent two or three standard units and request weekend delivery and service. Pricing for a weekend might range from $125 to $400 per unit depending on size and whether you add a deluxe upgrade.
Mercer Island winters are mild by Seattle standards. Average January minimum temperature drops to 36.9 degrees Fahrenheit, and annual snowfall runs 6.8 inches. That's less harsh than some regions, but winter rain is steady: the area sees 91 days per year with 0.10 inch or more of precipitation, the highest in the five-city metro. Our units sit on a stable, firm base that meets ADA Standards section 302.1 so they don't sink or tip in wet soil. If you're doing winter renovation work on the island, we keep units serviced and stocked year-round.
Mercer Island's main community venues include the Mercer Island Community Center and several public parks. If you're organizing a small gathering or sports clinic, check whether the venue requires you to provide portable toilets. Many island events in parks do because municipal facilities fill quickly. We're familiar with island parks and their access roads. Call us to confirm whether a specific location allows container placement or whether a permit covers your event date. For larger festivals or community gatherings, deluxe flushable units project a nicer image than standard ones.

How do I get an ADA accessible unit on Mercer Island?
An ADA accessible portable toilet must meet ADA Standards section 213.2: at least 5 percent of single-user units in a cluster, and never fewer than one, must be accessible. The unit includes a 60 inch diameter turning circle per ADA Standards section 304.3.1, a 32 inch clear door opening per section 404.2.3, and a 48 inch maximum forward reach for controls per section 308.2.1. An ADA unit costs $120 to $240 per week on a typical contract. Weekend rentals run higher. If your Mercer Island job needs ADA compliance, a construction site open to inspectors or a public event, one ADA unit plus one or two standard units is the usual mix.
When does a portable toilet need a handwashing station?
If your crew applies paints, coatings, herbicides or insecticides at your Mercer Island site, OSHA 1926.51(f)(1) requires a washing facility with soap and a hand drying device per 29 CFR 1910.141(d)(2). Hand sanitizer alone does not satisfy the rule. We rent portable sinks and handwashing stations that hook to a holding tank. Pair one with your toilet package on painting or chemical jobs. A handwashing station typically costs $60 to $220 per week depending on size and service frequency. See our handwashing station rental page for more options and pricing.
Can I rent a restroom trailer instead of a standard unit?
Yes. A restroom trailer holds multiple stalls, running water, mirrors and climate control. They rent by the day, weekend, week or event package. Daily rates run $175 to $2,500 depending on stall count and amenities, and event packages start around $2,500. For a wedding or upscale gathering on Mercer Island, a luxury trailer beats portable toilets. The trailer needs about 60 feet of straight clearance behind the delivery truck, so confirm your driveway width with us before ordering.
