I have bought from Bathstore a toughened glass over-bath shower screen which is curved like a bow over its length but square at the top. I cannot fit it because the weird shape of my Victorian house eves ceiling means that one corner needs to be cut away and shaped to fit. Any suggestions, can anyone cut it, or replace the glass at a reasonable price, or even replace with glass with something more malleable. Any ideas gratefully received. I live in Surrey
