My bathroom had a cheaply done vinyl floor install done. They didn't remove the toilet, just cut the vinyl around it. Why they would not spend the extra 5 minutes to remove the toilet I don't know. So urine was under the laminate for probably years. Removed the replacement vinyl, the original vinyl and the subflooring(not sure if that is the correct word, the 1/4" pressed board). It is better but still has a smell. What now? Any suggestions? I will be cleaning the floor once a week for awhile then apply kilz. Probably going to remove and replace the whole vanity also since the wood also has urine in it. These people must have been mentally handicap to not fix this issue.
