installing a shower curtain..I am wondering if I am doing it correctly...I think I am ..It may seem like a no-brainer but it is kind of hard for me to do..I am a lefty...lol Do i put liner & curtain on at the same time & the same holes .on the rod???..I want to have a center entrance but then if easier side entrance...Floor does get wet & around the tub is getting all rotted on the floor...Mobile Home so it would not be hard as floors are made of cheap wood
