www.toolsforhealing.com had a couple of ozonator's for drinking water (do not know if they were strong enough for bathwater or not) but I believe they were more than $200 by a few dollars. I know Hulda Clark sells one but it is $250 too...you might look on ebay though. I saw Hulda's sell for $150 on there...boy I sure did want to buy it! You might put ozonater as your favorite search and recieve emails when new ones are listed so you will not miss any. Maybe you can find something that route. :) Best of luck to you! Caitlin Lorraine
P.s. I bought a little ozonating filter for my fridge on ebay for $20 and have just loved it! My fridge has stayed so nice and clean, my veggies are staying good longer (cucumbers still firm after almost a month! never happened before...), no mold, and no mixing of smells. Really worth it I think!
