My appliances can last anywhere from 1 to 7 days and I even take a bath every day though I try not to get it too wet. The appliance and bag are separate in a two step appliance/pouch combo some come as one unit there for you could just change the bag out and keep the appliance longer. There are drops/tablets you can put in the bag to reduce smell. If you had this and a gentle toiletry scent spray you would have no issues, though keep in mind certain foods will smell worse than others and it's kinda interesting figuring this out. Unless the bag leaks there is no smell as it's an airtight system until you empty it. I've had maybe 5 pouch issues in the last 5 years and looking back I think they were all my fault, either not closing the tip enough at first and letting the appliance go a bit too far at night. As far as noises I only notice the noises when I eat either very fibrous foods or no food at all leading to a lot of built of air that needs to come out, but with a light snack things seem happy and no one notices anything. The sounds is very similar to a stomach gurgling when it's hungry and it's easy to blame any noise on a, "Oh I must be hungry.. sorry."
If you want as little risk as possible and to avoid the possibility of a failed Ileo jpouch I would suggest going with a total colectomy with an End Ileostomy.
With an Ileostomy you can pretty much eat whatever you want, pain free, I only struggle with keeping hydrated on the really hot days then again I'm quite active at my job. Which means I just have to focus on bulking foods and more liquids. Part of my hydration issue is missing Small intestine that was removed in the formation of the Jpouch that then failed, so you may not have this issue at all either as I did not when I originally had the Ileo's waiting for the 2nd/3rd step surgeries.
I think all of us here had a similar mindset, no one thought they were gonna ever go under the knife but the human being is amazing at adapting to any situation. For instance at work no one even knows I have a bag unless I tell them, also I had the 3 step Jpouch surgery (which failed unfortunately) but on the 3rd surgery you end up closing up the Ileostomy as they reconnect the intestine and this is the honest truth I kinda missed having the bag so I ended up going back to it, it's really not the end of the world and much better than suffering 24/7.
