RV Repair: drain, strainer basket, rv need

Question
we are trying to replace the walls in the bathroom of our RV need to remove the tub but can not get the drain out any advise

Answer
Hi Misty,
 There is a nut on the back side of the P-trap. If you can reach that and lift out the shower pan with the strainer still attached, that is the easiest way. If you can't. You may have to cut an access from under the floor. To remove the strainer nut. There is no easy way. A strainer basket wrench almost never works from the top side. Good Luck.
