Portable Sinks in General

What is a portable sink?

A portable sink is a self-contained and fully-functional sink that does not require any plumbing or installation as well as being mobile. The compact size (of most models) makes them easy to transport in a small truck or van and most models come with safety-lock casters for easy rolling.

Are portable sinks difficult to install?

Not at all. In fact, that’s the whole key behind portable sinks: they’re self-contained, easy to use and other than filling up the water tank and plugging it in, there’s no installation whatsoever.

Are portable sinks difficult to maintain?

No, MONSAM Enterprises’ portable sinks are specifically designed to be easy to clean, easy to maintain, and easy to use! Cleaning instructions are included with each sink.

How do I empty and refill the water tanks?

You simply take them out of the sink cabinet and either refill them or empty the waste tank then replace them inside the cabinet. We have a folding hand cart that you can purchase to assist you in this process. We also offer a flex tube which connects the fresh tank with any standard faucet to make it easier to refill the fresh tank.

How many uses does each sink provide?

Each 5-gallon tank provides an average of 40 hand-washing uses before it needs to be refilled. The number of hand washings increases if the unit includes an optional foot switch or motion sensor.

Is MONSAM Enterprises the manufacturer of the portable sinks?

Yes, MONSAM Enterprises is the leading manufacturer of portable sinks, with more than fifty models available.  We ship anywhere in the world.  That means exceptional quality and innovation for you and your customer.
