Shower technique is a great alternative for hydration. Also helps them clean their eyes/turrets of dust and dirt/irritants. I leave mine in the shower for about 15-30 mins. You want to let them settle in and have plenty of time to drink their fill and really clean out those eyes. Just make sure the water is lukewarm to the touch and not hot. Also you can direct the spray to bounce off the wall of the shower or tub but Ive never had an issue because my shower has a fine mist setting. I just set the plant up so that he/she can go in or out off the spray when they are done.
