We used Mick Banks of All Install and he was brilliant. He installed some extra cupboards in the kitchen for us and shelved a number of places for us. I am not sure if he does the shower screens but he is a time served joiner and is a craftsman who does a very professional job. He can fit curtain poles and put up mirrors, coat hooks etc and has worked for a number of our friends in Roda all of whom were delighted with his work.
He can be contacted on 0034626971670 and his email address is email@example.com
Hope that this helps.
