Küstenlinie®
WC seat

The toilet seat from KÜSTENLINIE made a very good impression in our test. With its oval shape , this bright white universal toilet seat fits almost any standard toilet bowl. The antibacterial urea-Duroplast material prevents any discolouration and is also particularly stable and resistant. The easily removable lid (quick release) makes cleaning easier. In addition to the soft-close mechanism, this toilet seat also comes with a transparent rubber stopper for the back wall so that the lid does not make any noise when it is folded back against the wall or the cistern. The ergonomically shaped toilet seat ensures a comfortable seat. What’s more, the installation of this product has been thought through to the end: thanks to a unique, patented template , the toilet seat is easy to fit on the ceramic without having to readjust or realign it. This simple installation from above enables quick and uncomplicated fitting with subsequent stable hold without slipping. The company’s excellent customer service is also worth mentioning, as it is available around the clock in case of questions or problems. All in all, a highly recommended product.

The first impression

The packaging and labelling

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be ensured.

*The maximum score is 100 points
WC seat was additionally secured with foam strips during shipping

The toilet seat from KÜSTENLINIE arrived in the Amazon box. The box was undamaged and easy to open thanks to the zip without the need for any additional tools. Inside the box, the toilet seat was packed in another box and in plastic film. The toilet seat was also secured at the top and bottom with foam strips. The plastic bag might not have been necessary, but it also protects the product from dirt and scratches and secures the small parts to the product. In this case, the product was fully protected and the toilet seat arrived in perfect condition, including all the necessary accessories. The packaging of the toilet seat is only partially recyclable. The plastic bag and the foam strips are not recyclable, but the cardboard box is. Overall, the toilet seat from KÜSTENLINIE makes a good first impression.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the pack complete and does the manufacturer make it as easy as possible for me to use the product straight away?

After unpacking, there were several things on the table: in addition to the toilet seat with lid, the necessary assembly material and the template for assembly were also included. The easy-to-understand assembly instructions were printed directly on the template and clearly illustrated. The small, transparent rubber stopper was also included in the package, but we almost threw it away with the packaging film on which it was barely visible . Better labe lling of this inconspicuous little accessory would have been desirable here to make the customer more aware of it. Information on the use and care of the product can be found at …. The contact information with company name, e-mail address, postal address, telephone number and website of the company are given in the … and the customer is kindly informed that customer service can be contacted at any time using the contact details provided.

The toilet seat from KÜSTENLINIE lives up to its promise and we really enjoyed testing it. Installation was really easy thanks to the patented template. The template helps the toilet seat to fit easily on the ceramic without having to readjust or realign it. This simple assembly from above enables quick and uncomplicated installation without slipping and with a stable hold afterwards. The automatic closing mechanism works perfectly. The transparent rubber stopper supplied allows the toilet lid to rest silently against the wall behind it or the cistern. The ergonomically shaped toilet seat ensures a comfortable fit. The easily removable lid of this toilet seat with the quick-release system makes cleaning easier. The high quality of the ISO-tested urea-Duroplast material also promises hygiene and stability. Thanks to the guaranteed durability of the product and the compact and largely recyclable packaging , the product can also be categorised as sustainable and saves resources. Last but not least, the company’s customer service is actually available around the clock. All in all, the toilet seat from KÜSTENLINIE is therefore a highly recommended product.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also analyse consumer reviews and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*
Price / performance ratioVery good quality and performance at a reasonable price 100 points
Rating cut4.6 out of 5.0 on Amazon 80 points
Total 90 points
Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.6 stars. There are occasional complaints that the soft-close mechanism starts to creak after a while. We were unable to confirm this in the test. However, we were unable to definitively rule out the possibility that this might be the case over a longer period of use due to the limited test duration. Many customers like the fact that the unique template supplied makes installation much easier. They also praised the automatic soft-close function, which works well and for a long time, as well as the easily removable toilet lid, which makes cleaning much easier. In our practical test, we were able to confirm that the product delivers what it promises. Installation with the template works really well and the toilet seat can be used easily and largely silently. The ergonomically shaped toilet seat ensures a comfortable fit. All in all, a highly recommended product.

Prices of up to €59.90 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €34.99. With a price of €49.90, the toilet seat from Küstenlinie is currently in the middle price segment. The price ratio is reasonable for the quality and scope of services offered.
