About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

Quest
Side shower seal

Manufacturer’s product description

A side shower seal like this 200-centimeter model from Quest primarily serves the purpose of reliably containing water leakage and making the shower more watertight overall. Transparent PVC ensures a discreet appearance that blends well with modern glass showers. Many users appreciate the 200-centimeter length because it can be easily cut to size, making it suitable for shower enclosures of various heights.

One advantage is the simple, adhesive-free installation, which requires no tools and is completed quickly.

Initially, the material is still somewhat stiff and only takes its final shape after a short time.

Overall, the impression is that of a functional, simple product that serves its purpose and integrates well into existing shower systems.

  • Tool-free installation
  • Transparent PVC blends discreetly into glass showers
  • Can be cut to size in 200-centimeter lengths
  • May be slightly bent due to shipping
  • Feels a bit stiff at first and takes time to adjust

Upon unpacking, the shower seal appears neatly packaged and adequately protected, so that damage during transport is rare. The transparent film and sturdy cardboard sleeve give a solid first impression. Due to transport, the seal arrived slightly bent but smoothed out completely after a few hours. A positive aspect is that no unnecessary parts or complicated installation materials are included, which makes getting started easier. A slight plastic odor is noticeable but dissipates quickly after unpacking. The 200-centimeter length is practical but can feel a bit unwieldy when handling it in small bathrooms. Overall, it gives a clean, uncomplicated impression that fits well with a simple, functional replacement part.

The workmanship appears clean overall, with sharp edges and uniform material thickness. The transparent material provides a subtle look that blends harmoniously with glass showers. The lip on the underside is slightly softer to better conform to uneven floors. With very frequent opening and closing of the door, the shower seal naturally wears out a bit faster. A positive feature worth highlighting is the material’s UV resistance, which reduces the likelihood of yellowing. The surface is easy to clean, contributing to a well-maintained appearance over the long term. Overall, the workmanship appears solid, even if minor material weaknesses may become visible depending on the installation environment.

In practical use, the shower seal largely lives up to its promise of improved sealing. Water is reliably contained, provided the glass thickness matches the seal and installation is done correctly. The simple, adhesive-free installation works well and meets the manufacturer’s specifications. The promised durability is generally achieved, though longevity depends heavily on the intensity of use. The transparent design remains clear over time, which also aligns with the advertising claims.

Overall, the product delivers on most of its promises, even if minor limitations may arise in everyday use.
