how big is that firepit jilly...im sitting here thinking of the old galvanized round tubs ...know the ones i mean...if that fire pit is large enough you could set that sort of tub in the middle...then fill it with water...then build a fire all around the tub to heat the water...when the fire dies down and the water is warm you could get in it...just dont put it on TOP of the coals...and leave a path for yourself to get in it.
