I installed steam in an all in one tub/shower. Has lamps, lights, speakers, whirlpool. The steam is awesome. Whirlpools are nice but steam goes to the bone. Great if you have a cold an will clear you up enough you can breath to go to bed and sleep. You don't need ventilation as one stated. It's enclosed and just turn the shower on, which you need to anyway to wash and the seam goes down the drain. Power consumption isn't even noticed on electric bill but then it isn't used every day...we love ours.
