Designing Kitchens and Bathrooms - Diverter Spout

My bathroom has a shower stall separate from the bathtub. However, my wife wants a hand-held showerhead added to the tub. I removed the old spout so to see what I needed to add a diverter spout. The old spout was slid onto 4 inches of copper tubing attached with a set screw. Do they make diverter spouts that attach the same way or do I need to do some cutting and reattaching of the copper tubing? Bear in mind that I'm not looking to spend a lot of money on parts other than the showerhead itself.

When you removed the shower head you should have a pipe with threads on it. That's all you need, just make sure your new diverter will screw on like your shower head did.

Maybe I didn't explain it correctly. I only have a bathtub (no showerhead) with a fill spout. I want to remove the old spout and add one that has a diverter so that I can attach a handheld showerhead. When I took off the old spout, there was about a 4-inch long, unthreaded copper pipe. The old spout was slid over that and attached via a set screw.
So, I'm curious as to whether they make diverter spouts that will attach the same way (slide over the extended copper pipe and attach with a set screw) or will I have to cut the pipe back and attach a male threaded end to it so that I can attach a new spout?

I've never seen a diverter spout made like you need.The design of yours suggests that the spout serves mostly as a decorative cover to a plain peice of copper pipe.You may need to have a threaded adapter soldered onto the existing copper so that a threaded spout with diverter can be installed.

So we've decided that I need to cut the copper pipe. I haven't really looked into how much pipe it takes with a diverter spout, but in general, how much pipe, including the threaded splice that I solder on, needs to be sticking out of the wall?

First buy the spout. The measure from rear of spout to the rearmost part of the female thread part inside. Then you can figure your pipe and mta as a unit has to go inside that female thread by about 3/8-1/2 inch further, depending on how many wraps of teflon tape you do.

Um, I don't want to assume too much here. What are you going to divert to? Unless your mixing valve was designed for shower + tub, a diverter won't divert anything, it'll just try to stop the water.

What is the hand-held supposed to be hooked up to?

Are you planning on using a tub spout that has an attached hose & handle? If so, get that first and work backward, exactly as the previous poster described.
