I have a replacement for my Grohe Ladylux Plus handspray (attached to the end of the pull-out hose). Do I simply unscrew the old one from the end of the hose?

Yes! If the threads match up you're good to go/ Good luck, Tom

I agree with Tom, Good luck.

Correct. Unscrew it . All done by hand. Make sure you get the same replacement sprayer for that particular model.

Back to you
