Urine odor is old and on natural dye rug.
The okorder for a list of hot water carpet cleaners, that may offer this service, or know of some one near by that does.
Send it out for a professional cleaning. Normally I'd recommend Nature's Miracle (or a similar enzyme cleaner) as I do for carpet and furniture, but for a natural-dye rug (and valuable, I'm guessing?), don't chance ruining it with a DIY remedy.
You can wash down the walls with a solution of TSP (tri sodium phosphate) which can be found in the paint department. Air sponges will help absorb the odour in the air. Finally, a really good primer/sealant and a good bathroom paint should take care of the problem. If that STILL doesn't work - the smell could be coming from the grout in the tiles (if any) around the toilet. In that case, lift the toilet and clean with TSP or bleach, replace wax seal, re seat the toilet and caulk around the base of the toilet. If you do use bleach and/or ammonia - DO NOT MIX THEM!!! They produce a very dangerous, nasty gas. Good luck!
