I use the hot tubs almost everyday, if they aren't too crowded that is, most often though I get one to myself, particularly if we are sailing in cool weather when hot tubs are the most fun, except it is tough to get out of them to dry off if it is blowing, snowing or driving rain. Never had a problem with picking up a skin bug from the water; attendants are continually checking water quality, but I can only speak from Princess, HAL and Regent experience.
Just got off the Caribbean Princess a few weeks ago, there are nine hot tubs on that ship while the huge newest Princess ships offer only six and one of the six has no jets. Two on the Caribbean are much hotter than the others which is about time they got the temperature exactly right for me. Those two are found along side the outside adults only swimming pool you can access from the Lotas Spa and Fitness center.
I find most shipboard hot tubs are a little too cool for my taste, probably because they let the older kids use them which might account for why the adults only only tubs have decent temperatures. One negative is when adults let their kids learn to swim in the hot tubs.
