it would be highly unlikely to transmit chlamydia from a toilet seat (unless there was fresh discharge on the seat itself) and next to impossible through a bath. i don't know if you are male or female but why do you have chlamydia? this is a very treatable infectious disease. one you have been properly treated and tested "negative" at the end of the treatment you no longer have chlamydia and cannot transmit it to anyone.
can u transmitt chlamydia thru sharing a toilet or sharing a bath? my child often bathe with me.
