A lady who does custom sewing in my neighborhood will be making a shower curtain for me at a fair price. As for the vinyl liner, I think I'll have to cut up a standard sized one, but the actual shower curtain should hide any jagged edges on the liner.

This site has some good options if you want a solid. they're pretty cheap. I'm tempted by the 84" length. Super Walmart had white hotel fabric curtain in 78" length for about $15. Some curtains are available in 70" wide instead of 72". Stall width is usually 54". That seems skimpy for a 47" shower.

In decorating-land (not bath-land), the rule of thumb is that the fabric should be 2 to 3 times the width of the window, depending on how much fullness you like, so a 72" curtain on a 48" stall sounds skimpy. I'm not sure if the rule holds true across the bath-land border though.

A 72" wide curtain is 1.5 times the width of your 48" shower stall. In my opinion, in bath-land, I think 1.5 times the width seems better than 2 to 3 times the decorating-land rule of thumb. I don't think it would be too much material.

I sure hope they didn't wait for 8 years for the latest reply!

Ha! Maybe it was more for my benefit than for theirs. :)
