Hi, our 60's house has a built-in shower, concrete walk-in floor and is lined with Seratone which hangs down about 15mm and is proud of the wall so makes a good drip edge. This was all fitted 6 years ago by a local builder but the lower edge of it is all now rotting. Another builder has been to look and suggested that we just reline it but use some stuff called 'showerline' which is faced with aluminium. The shower is 1200 x 900 and three sides are clad, the fourth is open with curtains. Now, the question is that this second builder has quoted us $4000-5000 to remove and reline and we wondered if this is a sensible figure? Also, is the suggestion of this new material a good one? What is the inside part of it made of? ie is it the same as seratone? Views would be appreciated.
