[Cob] cob shower stall?

[Jonathan Walther]

If I shaped a cob shower stall, and covered the walls with formica,
would that be ok?  Can anyone suggest some other smooth, waterproof
substance I could use instead of formica?  I'd like something I can
screw directly to the cob using masonry bolts.

The bathroom is generally a moist place; is there some webpage with tips
and tricks and recommendations about making cob bathrooms?
