Over the years in the various houses that I've lived in I've always seemed to have the same problem with curved bath panels.
Whether fitted professionally or by me, the curved part of the bath panel where it pushes in under the lip of the bath always seems to begin showing micro cracks after four or five years. These just seem to progressively get bigger until I end up buying a new panel. The cracks are longitudinal, not vertical.
I'm at that stage again now, having just ordered a new panel.
To prevent the problem reoccurring within the next few years I'm considering reinforcing the inside, non visible, curved area prior to fitting.
I'm torn between glass fibre, which can be messy or Isopon car bumper filler.
Any alternative suggestions would be gratefully appreciated.
I did suggest to Mrs. Blade that I could just make a wooden bath panel, but this was deemed unacceptable.
