I have disinfected the whole toilet inside and out all the way around the base and the walls and baseboards and floor around the toilet. it still smells like urine in that bathroom, I wipe around base to see if its leaking, but.I get nothing.

I assume your toilet bowl has the normal water in the trap - that the water level is above the top of the exit opening into the siphon (outlet curve) of the toilet, so you are not smelling sewer gases coming back up from the sewer pipes.

Commonly this is due to a wax seal leak under the toilet - cost about $125-175 for a Plumber to remove toilet and replace the $10 seal - plus any cost to clean up the subfloor area or repair damaged subfloor or flooring joists if the leak has been going on for a long time and has caused rot or a fungus farm to grow in there.

If you wanted to be sure where it is coming from, take a garbage bag or piece of pallet-wrapping shrink wrap and tightly seal it over the toilet bowl with duct tape making the seal with the bowl, air out room till there is no smell, then close door and let sit for an hour or so, then come back - if no smell, then bowl is the issue (assuming trap water is OK) - if smells again then probably wax seal failure though possibly a mounting flange corroded out. (The wax seal is a large beeswax ring that makes the water-tight seal between the bottom of the toilet and the mounting flange on top of the sewer pipe located under the toilet and roughly flush with the floor).

If still toilet bowl as source, then I would use several applications of liquid lysol cleaner or hydrogen peroxide cleaner, being sure to get fully up under the rim and around the water inflow holes under the rim - might need a large Q-tip shaped applicator to get into the holes.
