Who invented the shower heads?

Stefan Raab's "Doosh" shower head shows small weaknesses in the test

On June 3, 2013, Stefan Raab presented the "Doosh" shower head he helped develop. for the first time to a larger public. At a price of 29.90 euros, the good piece has since been available in every Butlers branch and should enable comfortable showering without your hair getting wet. Above all, ProSieben wants to appeal to women. Heim.de has had the shower head extensively tested. Four women and a man got into the shower for us and extensively checked all the functions of the shower head. It turns out that the shower head keeps its main product promises, but it also has a few weaknesses. Last but not least, its unusual shape causes problems.

To test whether "Doosh" can actually be installed as easily as Raab and the product packaging promise, the testers tried the shower head on their own private shower. We used the same shower head for all five tests to make sure that the connection is still tight even after multiple installations.

The criteria for testing the Raab shower head

In addition to the question of whether "Doosh" can actually be installed in just one minute, as promised, we were of course primarily interested in how pleasant it is to shower with the new shower - both with a concentrated water jet that only comes from the middle section of the shower head, as well as when showering with the hand shower and of course when the water flows out of all 204 jet nozzles of the boomerang-shaped shower head.

In addition, the testers should give a judgment as to whether the comparatively high price seems justified. At 29.90 euros, "Doosh" costs significantly more than many other shower heads. By way of comparison: With online shipping at Amazon, through which "Doosh" is also offered, a branded shower head from Hansgrohe with five different adjustable jet hardnesses costs only 17.90 euros. Even with a 1.60 meter long metal shower hose from the same manufacturer, the branded item is only 25.73 euros and is therefore still cheaper than the Raab shower head, which is sold without any accessories.

The installation of the Raab shower head works largely without any problems

At least when it comes to assembly, you don't miss such accessories. With all testers, "Doosh" could simply be screwed onto the existing hose. One tester needed additional tools in the form of pliers for the exchange, which was due to the fact that slight calcifications had formed on the thread of the old shower head and the hose. Another examiner also had difficulty removing her existing shower head from the hose and got male support to do so. With the other three testers, the exchange worked without any problems. The difficulties in removing the old shower can hardly be blamed on the Raab shower head.

All in all, "Doosh" largely fulfills one of its product promises at this point. You should be able to replace your existing shower with a new shower head in just one minute. This only worked for three out of five test persons, but the other two also rated the assembly as unproblematic. Nobody needed more than three minutes for the entire replacement, so that the installation effort is still absolutely within the framework. In all five testers, "Doosh" fitted onto the existing shower head bracket.

Raab shower head: comfortable showering without your hair getting wet?

The second and even more important product promise of "Doosh": With its special shape, which is reminiscent of a boomerang, the new shower head should enable comfortable showering without the hair getting wet. Already at the press conference for the product presentation, Raab made it clear that this is the most important advantage of "Doosh" over conventionally shaped shower heads.

The water does not reflect off the body because it is distributed over so many individual nozzles, which leads to a lower flow speed and thus less jet hardness. It is different with ordinary shower heads. If you lower it to shoulder height and then hit the neck, the water will often splash back because of the high pressure. In doing so, the hair would often get wet, according to "Doosh" inventor Raab. In addition, several women reported to him that they found it uncomfortable to constantly turn back and forth under the lowered shower so that all parts of the body could get some of the warm water.

Showering with the Raab shower head set to its full width is pleasant

On this point, "Doosh" is actually an improvement over conventional shower heads, which women especially appreciate. All of our testers found the very soft water jet, which comes at full width from the 204 jet nozzles of the shower, to be pleasant. Showering without the hair getting wet works "better than usual," according to the unanimous assessment. One test person even confirmed almost verbatim what inventor Raab explained during his presentation. "Since the water jet is very gentle in the wide mode, it does not splash off the shoulders as usual. And because of the width, the whole body is covered with water. Excellent!" Enthuses the tester.

More about water and wastewater

Another test person even noticed an additional benefit: when shaving your legs in the shower, the wide curtain of water is very pleasant because it means you don't have to constantly turn back and forth under a thin jet of water. The short-haired male test subject was less enthusiastic in our test series. He did not need his hair to stay dry when showering, which is why the effect did not have a positive effect on the rating for him. He complained about the shower feeling with the water jet in full width when you shower with your face to the shower.

But at least: Because the water comes out of the 204 individual jet nozzles with relatively little pressure with the wide jet, the hair of all our testers actually stayed dry. "Doosh" keeps this promise unreservedly.

Concentrated jet is also said to improve conventional showering

However, it is precisely this low water pressure that is disadvantageous for conventional showering. Shower head inventor Stefan Raab knows that too. "If I want to wash my hair, I need more power," said a friend who tested one of Raab's very early prototypes in which only the full functionality was available. That is why the "Doosh" available today has a toggle button in the middle of the shower head. At the push of a button, the water only comes out of the middle section. This automatically increases the water pressure as the same amount of water now flows out of fewer nozzles. "And with a pressure that you are not familiar with from normal nozzles," Raab promised the assembled journalists at the press conference.

The fact that you switch between the two functions with a button and not with a rotating mechanism has a very practical background: "Most of the time you have slippery fingers when showering and otherwise keep slipping," explains Raab.

Some testers complain about low water pressure in conventional showers

Switching using the button in the center of the shower head actually works properly, as our test subjects confirm. A more differentiated picture emerges with regard to the jet hardness, i.e. the water pressure that comes out of the nozzles in the middle part. "If you have any doubts, you can use it to mess your farm if you have decent pressure on the line," joked Raab at the press conference. In our test, however, it turned out that three of the five testers found the water pressure by no means higher, but rather noticeably lower than is the case with their own shower. "Too little water pressure", so the verdict of a tester. In our test, "Doosh" did not always keep Raab's promise that the pressure would be higher than with normal shower heads. In any case, there can be no talk of "farmyard kärch".

The Raab shower head is not well suited as a hand shower

The biggest weakness of the Raab shower head lies elsewhere: Its unusual shape with a width of around 40 centimeters makes it unwieldy. So "Doosh" is not well suited as a hand shower. Whether in a closed shower cubicle or in the bathtub with shower: several test persons reported that they had repeatedly hit the wall or the shower curtain with the shower head.

"Bad handling, the shower head looks too big," was one of the verdicts. "In narrow showers you bump into the walls every now and then. That doesn't appeal," was another assessment. And the boomerang-like broad shape of "Doosh" can become a negative factor not only when showering. "Too bulky for my taste, which would bother me when cleaning the shower," complained one test person. As positive as the "Doosh" shape is when you want to keep your hair dry, the shower head has to pay tribute to this shape when it comes to handling it as a hand shower.

Price / performance ratio of the Raab shower head was okay for the testers

Even if there are technically at least equal shower heads on the market that are significantly cheaper than the Raab shower head, our female test subjects did not find the retail price of 29.90 euros problematic. Not a single test person rated the price / performance ratio worse than "rather good". Once "Doosh" even got a "very good" in this category. Only the male tester, who benefited less from the "Doosh" benefits, rated the price / performance ratio as "rather bad".

Objectively, you have to state that you can buy a lot of technically at least equal products for 30 euros, but the price is apparently not so high that most consumers would notice it unpleasantly. Especially for the women who are primarily targeted as customers, the qualities of the Raab shower head seem to justify its price. In addition, "Doosh" is made in Germany, which explains the relatively high sales price to a certain extent.

Overall, the Raab shower head performed well in the test

All in all, "Doosh" was able to convince in our test. Above all, he can keep his two most important product promises "easy installation" and "comfortable showering without your hair getting wet". With the latter in particular, inventor Raab is trying to close a gap in the market and solve a supposedly existing shower problem for female consumers. The inventor will be delighted that all women in the test attested that his shower head had extremely satisfactory properties at this point, which were also reflected in the overall ratings.

All four female test persons rated "Doosh" in their overall assessment with grades between "2+" and "2-". For the male examiner, on the other hand, it was only enough to get a "4". No wonder: it does not benefit from the advantages of the Raab shower head, so that the undoubtedly existing weaknesses were more significant here.
