Can I insulate my bathroom floors from underneath? I have a crawlspace and 2 x 6 subfloor. If I can insulate, which type should I use? The floor joists are too far apart for filling the cavity with rolled insulation (Or do they make insulation that wide, the joists (beams) are 4 - 5 feet apart). Thanks.

I would opt to insulate the walls instead of the floor if water lines are in the crawl. Furr the walls with 2x4s @ 24" centers. Install batt insulation and apply a poly vapour barrier, drywall is optional. If you want to insulate the floor put the vapour barrier on first, then insulate. The insulation can be held in place with strapping under the joists.
