Replacing old bath Kohler fixtures to Moen

[Peter Morgan]

Hello,

I would like to replace my old Kohler bath fixtures (faucet,handle or temp regulator , shower head 🚿 with Moen brand fixtures.).

I hope the old cartridge is still in tact or I probably may have to replace that as well.

Is that doable? How much can a plumber typically charge for this installation?

Thanks

Thanks
