How to Choose A Portable Sink for Your School

How to Choose A Portable Sink for Your School

We first posted this article on our sister site All Portable Sinks. We sell portable sinks on both Kindermark Kids and All Portable Sinks. After getting a lot of questions about how portable sinks work and what to consider when purchasing one for your school, we've decided to share this information on Kindermark Kids as well. 

Please let us know if you have any additional questions. Our experienced team is happy to answer questions via a phone call, email or live chat. 


What is a portable sink?

A portable sink is a self contained sink unit that does not use traditional plumbing. It operates using a fresh water and waste water tank that are inside the cabinet underneath the sink. Most units we sell have a pump and heater that run on electricity for warm water so the sink will need to be plugged into an outlet. 

Here is an image of the inside of one of our child height sinks:


As you can see, the tanks are connected with tubing that is easy to connect and change when the tanks are full. The waste water tank is usually larger than the fresh water tank to accommodate other liquids that may be poured down the sink. When the fresh water tank is empty, you change both tanks, emptying the waste water tank. We sell extra tanks and fill kits to make it easy to change and move tanks and allow you to have an extra set on hand. Many of our sinks will allow you to get 30 or more 20 second hand washings on a full tank. 

What Sink Height Should I Order?

We have sinks categorized in two height options: child height and adult height. The child height sinks will have a counter height of 20"-26" and the adult height sinks typically have a 36"-38" counter height. For preschools, we recommend a child height sink. There is a toddler height 20" sink but most are 26"-28". You can purchase a step stool for classrooms with very young children that works well with the 26"-28"H sinks. We also offer a changing table that has a built in sink on the side for those preschool classrooms that still have children with diapers. 

For elementary classrooms, the child height will be the best fit for the younger grades and the upper grades can use an adult height sink with a step stool to make sure all students are able to access it.

High School students should be able to easily use an adult height sink and you can purchase an optional step stool as needed. 


Choosing sink materials

Portable hand washing sinks come in many different styles. The basins can be made of stainless steel or ABA plastic and the counter tops an be made with laminate, stainless steel or ABA plastic. Our classroom sink basins are made with either ABA plastic or Stainless Steel. Cabinet bases can have an aluminum or steel frame with melamine, laminate, wood or plastic sides. The best selling self-contained sinks for schools are the ABS and Stainless steel basins with melamine or specialized birch cabinets created for school use. We recommend checking with your local codes so you choose approved materials. If you call us, we can recommend the best sink for your needs.

Below you will see a photos of 2 of our classroom sinks. The white Lil' Premier ABS sink by Ozark River Manufacturing and the Clean Hands Helper 38" sink by Jonti-Craft with black ABS counter and stainless steel basin.



Choose where you will be placing the sink

We have sinks that are created specifically for outdoor use so we suggest purchasing a nature/outdoor sink for an outdoor classroom or garden since they are created with materials that are better suited for outdoor use. For sinks that will be used in a classroom, consider the amount of students who need access. We offer sinks with more than one sink basin  like the Double Basin Lil' Deluxe sink pictured below. If space is an issue, we can help with compact solutions. If they will be used within a classroom temporarily, all units are on locking casters so they can be stored when not in use. Our Kiddie Station is a changing table with portable sink that helps provide a clean safe environment for little ones and staff in daycare facilities and preschools that have children in diapers. 


We also carry specialty sinks for specific high school classes. These include a lab table with attached portable sink, a culinary cart with portable sink attached to a cooking unit and a portable sink with emergency eye wash for chemistry classrooms.

Choosing accessories for your portable sink

As mentioned above, we have a variety of accessories that make use and care of the sink easier. Step stools will be helpful when the portable hand washing sink is used for students varying ages. Fill kits include specialized tubing and a small roller cart to help you move and refill water tanks. We also offer a hands free automatic sensor that you can attach to the faucet so it turns on with a sensor instead of having students touch the handle. The accessory we recommend the most is an extra set of tanks so that you can have a filled fresh water tank and extra waste water tank on hand to quickly change the sink as needed. In high traffic areas like schools, this limits down time in sink use. 

Keeping Schools Safe

We are dedicated to helping you find hand washing solutions for your school so students have adequate access to hand washing sinks in order to lessen the spread of infections. We can help you find the best sink for your school's needs and budget. We accept purchase orders and offer volume discounts.
