I am replacing the shower head we currently have with a new one. The existing shower head used a 1/2" "S" shaped pipe with male threads on each end. The new connection is designed to end up flush with the wall and has just about 3/4" of thread exposed, but the connection inside the wall is in there about 1 1/4". I got a 1/2" male/male nipple and a 1/2" female/female connector, but that ends up being too long - it adds about 2".

Not sure how I can connect this without it being too long or too short. I also don't think I can move the connection inside the wall, as it is attached to the studs, and I don't want to take out tile, etc.

pipe inside wall

fixture + extension too long

There's a one-peice extension fitting that's a bit shorter. Might or might not be shorter enough; or too short. You'll probably have to order it or try a comprehensive plumbing supply.

Search on 1/2" pipe thread extension and you should get results. Male threads on one end, female threads on the other, one solid piece.

The other likely options would be select a different product more adjustable to retrofit installs, or fill the space between the wall and the fitting on a "too long" extension with some sort of accent tile of appropriate thickness.

    That McMaster Carr part looks like it could work but at 30.11 USD (dollar) plus what ever shipping charge that they will tack on makes it a hard decision to purchase it. This alternate choice amazon.com/2-pack-Brass-Fitting-Adapter-Female/dp/B079XT6TKK gets you two adapters for just 10.95 USD and shipping can me covered by Prime membership. The hex shape of the Amazon part will be way easier to get a socket on it through the hole in the wall as well.
