Non-woven batard form?
This is probably going to sound completely odd, but our cabin has a tiny little water closet under the stairs and I need to find/make a very narrow lavatory sink (6" deep max front to back) to go in it. In order to wash hands, the sink only has to be the width of your hand, but it would help if it were a rounded oblong so you could scoop you wrist and forearm through the trough to rinse.
Anyway, I'm posting here on TFL because I have a wonderful open weave french bread serving basket, and an equally lovely woven reed batard banneton which are the perfect size and shape... but obviously, being porous, aren't going to work to make a homemade vessel sink. I've been online searching high and low for a glass, glazed ceramic or metal vessel roughly the same shape and size. All I have been able to find are unglazed pottery baking pots, fluted brioche pans, and low-sided bread serving bowls... none of which will work for a functional sink either.
Do any of you know where I could source a waterproof bowl or batard form that might work? I'll even take poly if that's all I can find! Who would have thought it would be this difficult to find a wide, narrow-depth, somewhat squatty but not shallow, batard-like container?!
Thanks for your help!
