Replace bathroom basin tap & bath panel

We are looking to get two small bathroom jobs completed in Dublin city centre: 1. Replace the two basin taps in our bathroom sink with a new two-hole basin mixer tap (already purchased, images attached). 2. Replace our existing bath panel with a new panel (already purchased, images attached), including any necessary sealing. The main items (mixer tap and the bath panel) have already been purchased, exact catalog items purchased are shown in the images for reference. We are not sure if any additional small parts such as connectors etc. are needed, but we would be happy to pay for these if they are required. Location is IFSC area, Dublin 1.
