HandyShower is a multifunctional 3-in-1 personal hygiene system that can be used as a faucet, a shower or a bidet. HandyShower helps you conserve water anywhere you are.
Our patented self-closing valve mechanism allows you to control how much water you use.
Thanks to HandyShower’s nozzle swap, the device can be used as a faucet a bidet or a shower.
The device weighs only 400 grams and folds easily so it can fit any backpack, luggage or case.
HandyShower’s construction has been designed to work even in the most extreme conditions, with no defects.
Using the device is fast and simple. Setting up the device takes about 1 minute, changing the nozzle – few seconds.
HandyShower offers severals kits. Their costs (60, 80, 120 or 160 zloty) gives you the best price-quality ratio on the market.
HandyShower is a well-thought device suitable for diverse users’ needs. I believe that it will be a very useful device in humanitarian aid projects.
HandyShower is first and foremost simple and effective above average.

HandyShower is a water-saving and multi-functional sanitary device, which due to interchangeable nozzles can serve as a portable tap, bidet or shower. In short: small, lightweight and portable bathroom at your fingertips.
Due to the system of interchangeable nozzles, there are infinitely many uses for HandyShower. Besides the three main functions: a tap, a bidet, and a shower, HandyShower can be used for cleaning equipment such as bikes, kayaks or motorbikes, where the long nozzles are perfect in hard to reach places. HandyShower can be efficiently used in washing dishes, abluting during pilgrimages, cleaning a pet or in crisis situation during a failure or lack of access to sanitary infrastructure.
Our mission is enabling access to basic sanitary devices to everyone everywhere. HandyShower is indispensable in places, where access to running water is limited, e.g. at the desert or in areas affected by humanitarian disasters. HandyShower will certainly make life easier for travelers, camping enthusiasts, preppers, truck drives, dog lovers and biking aficionados, canoeists and pilgrims. HandyShower will surely be useful to those who like being prepared for the unexpected.
There are four different HandyShower kits. See the picture below.
HandyShower is the only one on the market that offers the innovative system 3-in-1, which considerably increases its functionality compared to a regular solar shower. Due to the interchangeable nozzles, the device can be used as a tap, a bidet, or a shower. Moreover, at the heart of HandyShower is the patented valve that facilitates the efficient use of scarce water. Teemer-push valve works friction less, which makes it very durable and creates a smooth, light movement thanks to which HandyShower is easy to use and adaptable to all your needs.
Water tank included in the set has a capacity of 2 liters. We are currently preparing a 10-liter version, however, if that is not enough for you, HandyShower can be easily connected to other tanks.
For a child it is sufficient, but for an adult around 3 liters of water is needed. Washing hands requires around 200ml of water, hence the water bag would suffice 10 washes.
HandyShower can be easily used with other tanks such as canister, solar shower bag, or even a bottle, however, they all have to be placed above the shower head.

Changing the nozzles is very simple: to remove or install the nozzle just turn it and pull it up/press it down. Click here to see:
HandyShower works according to gravity, therefore the water tank has to be placed above the shower head. Just put the water tank e.g. on the roof of the car or any other elevated place so that the tank is at least 0,5 higher than the device.
The simplest kit ‘Basic’, which constitutes of the shower head, the tube, and one nozzle weights only 95 grams. The Premium + kit, which includes all additional elements along with the pedal (for hands-free operation) weights approx. 400 grams.
To heat the water inside the tank, place it in sunny area and wait for around 2 hours.
Individual elements of HandyShower are manufactured in Poland, China, and Taiwan, and the assembly takes place in Poland.
We are currently in the process of testing the durability of the valve. First test lasted 8 months (8 hours daily). We managed to press the device 800 000 times, after which the valve started leaking. Click the link to see how we tested it: https://youtu.be/NvMRX91JdO0
Sure! Long nozzles 5 and 6 are especially designed for washing hands.
Of course, that’s how it was designed. In order to enable the flow of water, lightly press the head of HandyShower with your thumb.
There are many water valves and they all have different uses. Some are durable, others are cheap, and others are portable. Until now, however, there was no valve that would be small, light, durable, reliable and cheap at the same time. The HandyShower valve has been developed over many years of trials and experiments. We are still conducting durability tests – you can follow it here https://youtu.be/NvMRX91JdO0 or on our Facebook page, where we post updates on how many times the valve has been pressed.
The valve works without friction, which makes the operation really smooth, and it practically does not wear out. The valve was developed in accordance with the guidelines of organizations such as Oxfam or the International Federation of the Red Cross and Red Crescent; the guidelines can be found here (Household Handwashing Device). The problem is significant because many organizations announced contests for a handwashing device. The contests were popular among engineers all over the world, including engineers working for Boeing, Airbus or Formula 1.
HandyShower has been designed to work at low pressures, such as pressure resulting from gravity – from a bag hung at a height of 2 or 3 meters. The prescribed working pressure is between 0 and 0.3 bar. The device can be used at higher pressures, however, it requires some structural changes. We have also developed a higher pressure valve, you can see how it works here.
Yes, we are working on it. We are constantly researching and developing, so any tips or suggestions are always welcome.
Time of the flow is dependent on the height at which we place the water tank relative to the shower head. If we are using the standard short nozzle with 9 holes and place a bag with 1 liter of water at the height of 0,5m then the average time of water flow is around 50 seconds. However, if we place the bag at the height of 1,5m, creating a very strong pressure, then the time will be 20 seconds. When using a longer nozzle with one or three holes, the time of flow will be twice as long.
