Removable grab handles: There are also removable shower handles on the market that are attached by means of suction cups. The benefits of these grab handles: They do not need to be screwed to the wall and can be removed and taken away if necessary – for example on holiday. However, removable shower handles also have some disadvantages – for example, the wall surface must be firm, non-porous and clean to ensure that the suction cups are attached securely. In addition, a TÜV-approved safety indicator should definitely be installed to warn the user if the vacuum under the suction cups is no longer strong enough to ensure a secure hold. However, since such a warning may also be overlooked, a permanently installed grab handle is usually preferable in terms of safety.
