How stable would ethan-1,1-diol be? I suspect it would readily break down to ethanal + water?

In aqueous solution most aldehydes from hydrates, and an equilibrium exists, which is catalysed by acids:
RCH=O + H2O <=> RCH(OH)2
The extent of hydrate (diol) formation depends on the aldehyde, and is easily reversible. I have seen one reference to the extent of conversion as being 50% at equilibrium.
I would therefore expect ethane-1,1-diol to be not very stable, and revert to ethanal, as you suggest, if you tried to isolate it.
Risk assessment
Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website.
