Don't forget that with ambient dry subs, the more room, the more air, and the
more air, the more it has to weigh to dive.  Air has a buoyancy of 64 lbs. per
cubic foot.  It adds up fast.  A space 2 feet deep, 2 feet wide, and 5 feet
high is 20 cubic feet (not exactly roomy) and would have a buoyancy of  about
1280 lbs.  At 31 cubic feet, you need a ton to sink it... unless you use a
'flying' design which remains positively buoyant at all times.
