Thanks so much for commenting!

I would love to consider a wall-mounted extension arm as an option, but I haven't been able to find one that is long enough. If you have suggestions for sourcing, please let me know.

Also, we're moving to more modern-looking chrome fixtures, and the freestanding options that I'm finding are either rather Victorian or the handshowers have a shape that really is not conducive to using as an overhead shower (e.g. see attached photo for the most common modern option).

If we can source an extension arm, do you think we would be able to replace the handshower with a more functional option and replace the attached tube (so it can reach the extension arm)?

I would consider going in to a local plumbing supply store. Speaking directly with these specialty showrooms like a Delta, Kohler, Etc. will have options that may be for retrofitting old spaces. Sometimes there are options in these showrooms to add components like the hand held onto a new fixture set up. I think you solution is going to be a custom fit in order to meet your modern decor. It will be worth your time to visit a few showrooms to hear some alternative options. Take some good photos and dimension of the tubs height, width and the wall distance you have between your tub.

Ditch the whole setup. Clawfoots are a giant PIA to shower in and would be extremely undesirable for a tenant. Not to mention the giant risk of moisture damage that you have with them. Especially with a tenant who will not be at all careful. Now you have a 15K insurance claim with mold remediation.

Put in an alcove tub with properly waterproofed walls.

Just plumb it completely separately.

I would hate cleaning around the clawfoot tub. And it does seem like a terrible idea with tenants.

@sophie - LOL :) I totally hear you. I would love to ditch the stupid tub altogether. The only catch is that this remodel is a "temporary" one. When we move back from overseas we need to tear down the entire back section of hour "habitrail" house and start over, so I don't want to go whole hog on this remodel—else my husband will have more ammo for not doing the full shebang. (I'm coordinating the remodel from more than 8,000 miles away, which is hugely complex.)

That said, maybe your mold comment will change his mind. The tub is massive and is definitely fabulous for a nice bath, but beyond that it's a huge PITA and space hog.

I think I've seen things like this in old homes, where a pipe with head attached went straight up from where you faucet is and had a head bent inward toward the tub. There was also a shower curtain rail that surrounded the tub.

But I haven't see such a thing in 60 years.
