I've completed the demolition of my old shower, but am puzzled now. I am on a slap foundation. My drain pipe is not centered, and it rises about 2 inches off the slab. It does not appear to have weep holes, and I cannot remove it. Is it necessary to have the weep holes, and does it need to be removed?

From what I have read, my next step will be to lay down my curb, which is another challenge. My supply pipes rise 8" above the slab where the curb should go. Should I make my entire curb 8" high, or just the part by the pipes? Should I use 2x2's instead of 2x4's so my curb will be on both sides of the pipes?

Here are some pics of my issues:

Hi Darren,

I don't see anything raising above the slab unless you haven't removed the mortar yet. You first step should be to prepare the drainage. Break out the cement around the drain down to the trap. Then convert to 2" PVC and bring it above the slab. If you haven't already done it clean up the slab and then install bottom half of the adjustable type flange
drain. ( see: http://www.lawsupply.net/odds_ends/drains/ ) The weep holes are in the flange. Frame the base in with 2 X4's and make the front curb The average is 4" but you can make it higher if you wish. Next will come the shower pan made from Blue Compaseal. Now comes the top part of the flange ,(the part containing the weep holes and adjustable drain). You are now ready to mud and tile, but first you must clean up the slab and get rid of the old drain and raiser. Good luck, Tom

I guess from the angles of the photos, you couldn't see the drain rising above the slab. I'll add one more picture showing it.

No need. The left hand side of the window was covered by a pop-up and I missed the "stub up" that didn't turn out to be a stub up at all. What you have left is a cast iron body adjustable flange type shower drain. To see what they look like click on the link I gave you and check out the cast iron flange 6 pictures down. Before you go any further you're going to have to break out the old cast iron flange and the drain that screws into it. Since the old flange is recessed into the cement the stub up will have to be increased so that the new flange will set level with the cement floor. Next will come the shower pan made from Blue Compaseal. Now comes the top part of the flange ,(the part containing the weep holes and adjustable drain). You are now ready to mud and tile. I wish In could say that the old flange and drain looks useable but since the upper and lower flanges are bolted together it looks hopeless. You do know what the functions of the upper and lower flange, weep holes and the Compaseal shower pan are don't you? If not call in some outside help, preferably someone with cast iron and lead joint experience. My advice. Frame in your shower including the front curb and call in a plumber to set the cast iron flange and adjustable drain, pan out the shower and rough in the shower valve. That will leave the mortar and tile work for you to do. To check on how the average tile shower floor's installed click on, http://www.compotite.com/skyblue.html Another link to check out is http://www.compotite.com/blue_inst_eng.htm Good luck and I apologize for not picking up on the other two pictures.
