    • I ordered from NSS after finding one of their really helpful ‘how to’ videos online, which went as far as giving the right part numbers. Good price, rapid delivery, easy fit and a shower that is as good as new.

    • I am not a plumber and after watching National Showers Spares how-to video on YouTube I found the part easy to fit, it was a straight replacement for the old one - in and out done in under half an hour.
      Everything you need came with the kit, new seal and Silicone grease, all made to the same quality as the original one.

    • I have a Mira excel shower post 2002 and the hot water supply stopped so I pulled the cartridge out and found that the hot water inlet wasn't opening as the plastic that slides the Bakelite plate has snapped. just wondering if that part can be sold separately?
