@dgroves0430 I also like hot baths. I don't do anything special with my ostomy - just fill the tub with water and get in. I like to use bubble bath, or bath salts, but be aware that bath oil may compromise the adhesive of you appliance, so you might want to stay away from that (unless you plan to do a change right after of course!). Once you see how your appliance does in a bathtub you'll have more confidence for a hot tub. You might notice some lifting on the edges of your appliance from a prolonged soak, if you do, you can always use tape to "picture frame" the appliance.
Of course wait until your medical team clears you for sitting in water (not usually the best thing to do with new incisions).
What are you after with scented tablets or spray? Do you want to deodorize the contents of your bag, or have something pleasant smelling on the outside? There are a variety of deodorizers on the market, and you can find them at medical supply companies (which is where you would probably be ordering your appliances). Things like Holister M9 drops, Brava Lubricating Deodorant, or Adapt Lubricating Deodorant are options. Another one is to put an Altoid peppermint into your bag (WOCN suggested). If you want something to smell pleasant on the outside I think that some scented spray might work? Or scented powder.
Depending on what brand you have, there should be a stoma cap that works with your appliance, and again, you can order these where you order your appliances. There are also wraps that cover the bag, if that is a preference. Ostomysecrets have intimacy wraps, and you can find these at a variety of places (including Etsy).
What other concerns do you have?
@susanf8 what I use to cover the bag is called a stomacloak. They come n different sizes, depending on type of bag. They are somewhat expensive, but they can be washed. They are leak proof so it provides peace-of-mind when out and about.
