    2 inch bath tub drain
    Anyone know of an online supply house that may have a 2 inch bath tub drain replacement? I have to replace the drain and over flow on a project at a 1940 house. The old drain was 2 inch. I've done a lot of searching but have come up empty handed. Any help would be great. Thx.

    I have never heard of 2" drain and overflow for bathtub. But it doesn't mean it doesn't exist. Question: where did you measure the 2" ? Can you post a photo of your drain and the tub ? Back to you...

    Thx for the response. Been busy on the same old house. I'll try and post a pic later today. I'll also double check the measurement. I believe it was inside to inside, but I'll make sure.

    Usually, the tub drain and overflow, trap arm and trap are 1 1/2". It connects to 2" pipe with 1 1/2" vent. Please, double check the measurements.

    Hi all...

    As Milo has discussed, tub waste and overflow assemblies (see image) are usually 1.5" (1.5" outside diameter) tubular size brass or plastic nowadays. Older clawfoot tub waste and overflow assemblies were 1-3/8" (1.375" outside diameter) tubular size metal.. the only exception I know to tub waste and overflow assemblies being a true 1.5" tubular size.

    A tub waste and vent are usually 1.5" piping (~1.875" outside diameter), but the tub waste can also be 2" piping (~2.375").

    You can transition from any pipe material to a tub waste and overflow assembly using a shielded MISSION clamp.. see image. These are available at any plumbing supply store.

    Bring all outside diameter measurements with you.

    Let us know if you have more questions...

    Hey, Mr. Da Nile,
    Did you ever find a replacement for your 2" tub shoe & drainpipe? I am having simaliar problems. I do have a gaping hole in 80 year old tub,(cast Iron i believe) the actual hole size is like 3" across. A brass tub shoe had to be cut out from below in basement, it was threaded into a 2" drain pipe that was pressure fitted nut into a T that was tied into galvanized line. I have stumped 3 plumbing shops that cannot help me, their only advice is to replace the tub. I dont have that kind of $$$$. I just cannot believe the "so called experts" that have never heard of 2" drain pipes?? And if our ancestors used them long ago,, why don't they have some sort of a reducer for such items of need? If someone did that? Then they would be titled to "EXPERT" status.

    Your 80 year old tub is just like me.
    Too damm old to repair and replace parts on.
    Time to think about a shiny new tub.
    However, I'd call around some 0f the plumbing repair shops and ask if they have any old drains in their bone yard. Most repair shops keep a "bone yard" of old toilet lids, fittings,etc, for just such a occasion, Good luck, Tom

    Hi,

    I have a 2" Kohler drain. The threaded portion is 2" not 1 1/2" like the new standard is. I know your frustration. Every shop I called treated me like a fool who was measuring the diameter of the flange. I wound up buying a drain key and popping the drain out to bring with me to a shop. The guy pulled out his old Kohler manuals and found my assembly on the first page of his oldest book on his shelves. I have all of the part numbers now for the assembly.

    He said, regrettably, that no one would have these parts in stock just based on age alone. (My house is from 1917 and he estimated the drain design to be 1955-1960) But his kernel of knowledge he gave me was to use my Dremel to polish the stopper's edge and the drain's edge. So I went home and plugged in the tool, got the polishing pad that is marroonish in color and bristled webbing, turned it to 20k and went to it.

    IT WORKED LIKE A CHARM!

    My drain holds water, and 50 years from now when I have to do it again, I'll make sure to remember this.

    I hope this helps anyone who is searching on this topic. It was a long process for me, just to get past the disbelief people had about a 2" drain.

    Hi PBJ:

    2" tub waste and overflow assembly...nope, not made!

    2" basket strainer for old tub waste and overflow assembly... yup! In fact, I've ripped a few of those out before... ;)

    Thanks for posting your experience with this! Surely will help someone down the road.

    Have a great night...

    My Clearpass Concealed Pop-up drain with overflow assembly would beg to differ. It is a 2" drain attached to a 1 1/2" pipe.

    Maybe I am using the wrong terms.

    Hey guys. I ended up using an off the shelf drain assembly that just fit,and then getting a guy( who was refinishing a claw foot for me) to touchup what the new drain did not cover. I think there are drain assemblies out there that will replace the old 2 inch, but I got frustrated and gave up. Lol. Good luck . On to newer probs for me. : )
