The Bain Ultra tubs (and I would think most airbubble tubs) are very low maintenance unlike many whirlpool tubs that need monthly cleansing cycles. Resale-wise I think alot of people are looking for a master bath with a tub that does something therapeutic, so I don't think it matters if it's air or whirlpool. If you're not worried about resale, I would say do what you feel is right for your lifestyle. Having the air gives you the choice of using the tub as a soaker or as a therapeutic option if your back is hurting, you've pulled a muscle, etc. With the soaker, soaking is the only option you have. I personally, like to leave my options open. Just my $0.02.

angie, you might get more help on the plumbing forum :) Monica

And another nut bar hit's this site. You have been given most perfect advice from some of the best boys on this site. Why don't you listen ? 104F is the safest temporary temperature rize for the human body not to excede a 15 minuet time frame. After you alter the thermostat canceling your U.L. approval your tub now become not legal and insurance companies love that. How are you going to alter the high limit after you screw with the stat ? Most of those tubs come with timers. Is that going to be altered ? Do you have any idea how poisonous chlorine gets after it is heated behond safe levels ? And what is that safe level ? Do you have any idea how stupid it is to shut off the pump with over heated water ? I guess not. The water now does not move. You are now in a poaching tub. Sorry, i take that. I know you will leave the tub when you get too hot, but let's say your not feeling well. Had a bad day. Under medication or not up to snuff. Fall asleep, Wake up dead. Then what ? It could happen. I was a power engineer at a holiday inn for years and have pulled many unconscious people from the wet sauna ( and we locked it off at 104F. with an outside manual timer maxed out at 15 minuets. We took the water away because they were flooding the heating elements and shorting them out so they went to the pool and poured chlorinated water from empty beer cans onto the heaters. Chlorine poisoning and burned lungs. Nice vacation. I guess you have already made up your mind and we will not turn you. Good luck and be carefull. Maybe warmer clothing when riding your bike ?

If I want to take a bath, I want to be able to stretch out my legs. Babies have shorter legs :-) I sat in the Kohler Underscore yesterday 60 x 30 and the lumbar support is awesome! I'm 5'7" and had another 3 inches for my feet so could stretch my toes too! I need an alcove tub. https://www.us.kohler.com/us/underscore-60-x-30-alcove-bath-with-integral-apron-integral-flange-and-left-hand-drain/productDetail/bathing/1302655.htm?skuId=1302576&brandId=656492
