There are various types of sanitary appliances on the reuse market: washbasins, slop sinks, toilet bowls, bathtubs, etc. And they come in many different styles.
Ceramics and enamelled cast iron usually stand the test of time very well. This is partly due to the ease of maintenance and the possibility of thorough cleaning of these elements. This is less the case for plumbing, which is why reused sanitary ware is usually reinstalled with new pipes and taps. For most companies offering these elements, they are part of a larger product range.
Sanitary ware with a special aesthetic (e.g. enamelled cast-iron bathtubs with lion's paws from the end of the 19th century, austere washbasins from the 1950s or frivolously coloured ones from the 1970s, modern hanging toilets of high quality, etc.) are much in demand for projects looking for a certain cachet. More anonymous quality products are often installed in public facilities (bars, restaurants, cultural centres, etc.).
