Carado shower tray broken after only three and a half years ! Unfortunately, the Hymer-Zentrale in Bad Waldsee rejected a Kulanz exchange of the shower tray of my Carado T 344, although there is clearly a material error + installation error. The shower tray is at the broken point near the edge very thin and not properly underlaid. The damaged place is about 5 cm long with subsequent thin crack of about 20 cm length.The repair costs with replacement of the shower tray at a The Hymer dealer is 1280-€ to 1400-€. From Hymer to the replacement of the shower tray is advised,as a safe sealing of the plastic tray can not be guaranteed due to the special antibacterial plastic. Who has experience with sealing of carado shower trays and can help me? Which material can the plastic tray be sealed with at least cost-effectively? For a replacement of the shower tray all shower enclosure walls would have to be equipped with In addition, the washbasin and the complete toilet have to be removed. Which company in the Munich area or Schwäbisch Hall (winter stand of my Carado) can seal the shower tray safely? Thank you in advance for your help HM10
