Why not try using a few drops of Lavender and Tea Tree Oils in the bath. This is a good synergie and has healing properties. They are both anti-infectious, and anti-viral. Not only is is good for you but you can also use it to clean the tub! I do enjoy a bath from time-to-time and I have never suffered with bladder infection - maybe because I always use essential oils in the bath. Good Luck.
