Can you replace an existing shower faucet (in my case mixet) with a different brand?

Hi Raydarag

Absolutely! There should be no real issue to stop you as most of the work will be done from behind. Just be sure that the new trim plate covers the old hole and you should be all set!

If needed, they make a remodeler plate (see image) to cover any holes from an older 2 or 3 handle valve being changed over to a single lever valve... ;)
