If you just want a shower, it looks like Minute Suites offers one for $25 (up to 30 minutes).

If you want a shower and full lounge experience, the Club at DFW charges a $50 fee.

Both of the above are open to any passenger.
If you have an Amex card, $50 will get you into the Centurion lounge. It's often considered the best lounge in the US, though reports lately are that it can get crowded, so there might be a wait for the showers, or they may even turn you away.

Finally, assuming you're flying AA, there's the Admirals Club. Also $50 for a day pass, or $99 for a 30 day pass.
All of the above are found in Terminal D, which will be used for both your flights (since they are international).
