I am remodeling our old standup shower in the master bathroom. There was an old fiberglass shower pan that I removed. I couldn't figure out how the drain was attached so I used an angle grinder to cut the fiber glass around the drain and remove it. It's a brass drain attached to galvanized pipe. I couldn't budge the ring that tightened around the threads of the brass drain so I used a dremel tool to cut a slot in it and it came off.

The problem is the drain is still firmly attached to the galvanized pipe, but I can't see how. My plan is to replace the drain and pour a concrete shower pan that gets tiled over. The simplest thing to do would be to remove the existing drain and just attach a new adjustable one onto the galvanized pipe. Is this possible or do I need to cut the galvanized pipe? I am working with a concrete slab foundation and don't have a lot of room to work. I've attached a few pictures to hopefully show whatever it is I have left out. Any help would be greatly appreciated.

It looks like the strainer is LEADED in, so it can be tricky to remove. In this case, for us to be able to really help you, you'll need to tell us what kind of shower pan you'll be using... vinyl membrane, copper pan, hot mopped tar,etc.? Once we know the type of pan we can tell you how to proceed.

You can always cut it of 6" below the old shower head, install Fernco coupling, short piece of pipe and new shower drain head. Chances are that you will damage the old pipe during old drain head removal and as a result, it may not seal properly. However, as Mark asked above, we need to know what kind of new shower pan you are going to build. Each pan installation may require different type of drain head.

Back to you
