Tricks to remove shower?

[Dogwaggin]

I’ve removed the toilet, and removed the screws holding the flange down.  Are there any tricks for removing the toilet flange and the shower drain? They don’t seem to unscrew or pull up.  Do I need to drop the tank?  Thanks for any help!

I’m going to answer my own question just in case anyone else looks for this information.  
 

The toilet flange just required a pry bar and a hammer and a bit of brute force. Once the flange started turning counter clockwise it unscrewed from the pipe going in to the waste tank.  

 

The shower drain took a bit more effort.  First we had to go underneath and disconnect the p-trap.  Then needed both  a tub drain wrench and an adjustable locknut wrench.  This part was a two person job. It was a compression type fitting but the castle nut was recessed so we couldn’t really get a wrench we could turn on it.  So one person had to get underneath and get the locknut wrench wedge against the castle nut and then in the shower above a second person used the tub drain wrench to turn the fitting.

Sorry, I missed this - yes they overused the silicone holding the toilet flange and it takes force.  So, what are you doing - complete shower removal?

Yes I was able to completely remove the shower. The shower drain was actually quite a bit harder than the toilet flange.   It took a little effort but I got the shower out  in one piece and may decide to reinstall it when everything else is done. There was a piece of plywood (1/2 inch probably) that was glued to the top of the shower and wedged in between the shower and the roof, plus the air vent was screwed into it. Some of the plywood had some rot and I pulled it out easily but most of it was solid and I ended up using an oscillating tool to cut sections out and also used a scraper to pry the glue apart. That piece of plywood had to be removed in order to move the shower because it had it wedged tightly to the ceiling, especially in the corner near the hatch.  Once the plywood was removed I was able to slide he shower to the center of the rig. Since it’s a rear hatch I was able to utilize my Tetris skills and turned the shower to the side and got it out! I was surprised that the floor underneath is in great shape.  I wish the same could be said about the other side under the propane cabinet.

Here’s a pic of the shower once I was able to move it out of the corner. You can see the floor has damage under the propane storage box.  You can probably also see the bow in the floor which is particularly bad in that rotten corner.  
To get the shower out I had to tip it to the side and then turn it to remove it.  I couldn’t tip it toward the front or back because there wasn’t enough clearance.  I couldn’t slide it straight out because there is a lip at the rear hatch.

Wow, I can't believe you got that out the hatch?!  Mine had to remain in the rig while I did all the other work, then I slid it back in place.  If you are re-using your shower, check my thread on an easy way to keep rodents out from the gaps in the floor where the toilet drain goes.

The only way I got it out was because it’s a rear hatch. Not 100% but I think I’m hoping to reuse it.  Thanks for the tip on rodent proofing the plumbing area.
