Private Restroom Trailer Rentals across San Mateo, California

Yes. Our ADA + 2 has a full accessible unisex room with grab bars and space to turn a wheelchair, plus a self-contained ramp built to the California standard. It also has a women’s room and a men’s room on the same trailer. We set the ramp on level ground close to where guests arrive. For graduation parties and church events, it is usually the first unit we suggest.

Most of the time, yes. We ask for the address, a photo of the driveway and the gate width, then plan the route and the turn. Our trailers can be leveled on jacks and blocks on a moderate slope so the floor sits flat. If the driveway is too steep or tight, we set the trailer on the street side of the property or in a nearby flat spot and plan the path for guests.

For most weddings that size, yes. The 5-Station handles about 150 to 450 guests, or 200 to 500 for a five hour event. A long open bar pushes use up, so for 200 guests and a late night we sometimes pair the 5-Station with a 2-Station near the dance floor. Tell us your guest count, your hours and whether there is a bar, and we will size it for you.

We put it close to the site office or the sales trailer, on firm, level ground, with a clear path for our service truck. A long-term trailer needs a standard outlet and a spot our pump truck can reach every week. We service it on a fixed day, pumping, refilling water and restocking. Rentals can run for weeks or for the length of the build.

For most events we deliver the day before, so the trailer is set, leveled, tested and stocked with time to spare. For a Saturday wedding, that usually means Friday afternoon. Pickup is normally Sunday morning or Monday, at a time that respects neighbors. For graduations and school events we can work around the campus schedule.

For a one-day event, the onboard fresh water tank is usually enough, and no hookup is needed. For multi-day festivals or long rentals, we either refill the tank on each service visit or connect to a garden hose spigot if one is close. Waste goes into a sealed tank either way. The only hookup almost every trailer needs is power.

Book as soon as you have a date. September and October are the warmest, clearest months on the Peninsula, and fall Saturdays fill up first. Graduation week in late May and the June fair window also sell out early. Three to six months ahead is safe for most dates. A call to us takes five minutes and holds your trailer.

For large events, yes, we can. An attendant keeps paper, soap and towels stocked, wipes down rooms and keeps an eye on the tanks during the busiest hours. For smaller parties, we stock the trailer heavily before guests arrive, which covers most weddings without anyone on site. Multi-day events get a full service between days.

It can. The city’s special event guide says events expecting 100 or more people may be required to provide portable restrooms, depending on how long the event runs and where it is. Park restroom buildings may not count as enough. We can give you the trailer specs and a footprint for your site plan.

Often, yes. The Event Center has wide paved lots, which makes setup quick, and Coyote Point has room near its picnic areas. Call us with the date and location, and we will tell you right away what we have open. For emergencies like a burst pipe or a flooded building, we move as fast as our schedule allows.

The trailer is fully enclosed, lit and heated, so guests stay dry and warm inside. We set it on pavement, firm ground or plywood when lawns are soft from winter storms. Steps have handrails and non-slip treads. If you are adding a tent, leave room for a covered path to the trailer doors.

Before any trailer goes up a hill street in San Mateo, a few questions save a lot of trouble on delivery day. How wide is the gate at its narrowest point, post to post? Is the driveway paved the whole way, and how steep is the last stretch? Are there low oak limbs, wires or eaves over the route? Where is the nearest outdoor outlet, and is it on a circuit that also runs a pool pump or a hot tub? Take a few photos from the street looking up the drive, and one from the spot where you want the trailer. Send them with the address. Most hillside setups go fine once we have seen those photos.

Placement on a slope is about the floor, not the wheels. A trailer can sit on a moderate grade once it is leveled on jacks and blocks, and that keeps the doors closing right and the sinks draining the right way. Pick a spot guests can reach on a flat, lit path, away from the tent’s main entrance but not hidden. Keep it at least a few feet off a neighbor’s fence. On winter lawns, plan for firm ground or plywood instead of grass. Ask your neighbors to keep the curb clear the day before, because a delivery truck needs room to swing the trailer into the drive.

Many houses in San Mateo Park, Baywood and North Central were built with one full bathroom, or one and a half. A full remodel of that bathroom can take six to ten weeks once tile, plumbing and inspections are done. Families try to get by with a gym membership and a neighbor’s spare room. It wears thin fast, especially with kids. A 2-Station trailer in the driveway gives you a toilet, a sink and a mirror a few steps from the back door, with heat for winter mornings. It plugs into a standard outdoor outlet.

Ask your contractor for the real schedule, then add two weeks. Most remodels run long, and a rental that ends early is easier to handle than one that ends before the new bathroom works. We service long-term home units on a fixed day each week, pumping and restocking while you are at work. Plan where the trailer will sit so it does not block the dumpster or the contractor’s truck. When the job wraps, we pick it up on a weekday morning and leave the driveway as we found it.

On New Year’s Eve 2022, San Mateo got about five inches of rain when about one inch was expected. Streets near Borel Creek, Sunnybrae, San Mateo Village and Laurelwood Park flooded, and pump trouble at the Marina Lagoon station made it worse. Storms like that do not just flood streets. They back up sewer lines, knock out power and shut down restrooms in restaurants, offices and churches for days. A business that cannot offer a working restroom often cannot stay open at all.

A backup plan is simple. Know where a trailer could sit on your lot or in the alley, and where the nearest outlet is. Keep our number with your building contacts. Our trailers carry their own fresh water and sealed waste tanks, so they keep working when the building plumbing does not. A 3-Station covers most small restaurants and offices, and an ADA + 2 covers places where accessibility matters. The federal Ready.gov flood page lists more steps for your building.

Start with ownership. Ask whether the company owns the trailer or is booking it from someone else. A broker cannot always tell you which unit will show up or who will service it. Next, ask what the station count is, how many guests and hours it is rated for, and what it needs for power. Ask whether delivery, setup, stocking and pickup are included, and what service between days looks like for a multi-day event. Ask whether the trailer has heat as well as air conditioning. Peninsula evenings get cold fast in June.

Then ask about the site. Will they look at your driveway or lot before the date? Can they level the trailer on a slope? Do they have an ADA unit, and is it free on your date? Ask what happens if something goes wrong during the event and who you call. A good company answers all of this on one phone call, in plain words. If a quote leaves you guessing, call us and we will walk you through ours, line by line.

Coyote Point Recreation Area is one of the most popular spots on the Peninsula for company picnics, with group sites near the marina that come with tables and grills. San Mateo County Parks takes reservations up to a year ahead, and groups planning to bring more than the site includes are asked to call the parks reservations desk first. City parks in San Mateo rent picnic areas online too. Park restrooms are shared with everyone else in the park that day, and on a sunny Saturday the lines get long.

For a company picnic of 150 to 300 people, a 5-Station near your site keeps staff close to the food and the games. Tell the parks office early that you plan to bring a mobile restroom trailer, so they can tell you where it may park and what access the delivery truck has. Pick a spot on pavement or firm, level ground near the road. Our trailers bring their own water, so you do not need a tap nearby. Schedule delivery for the morning of the event or the day before, and pickup after the park closes.
