How to replace wall mixer?

[matteo917]

Hello Team, I’m planning to refresh my bathrooms with new tapware and some other things. I asked a quote to my local plumber and I was told in order to change the wall mixer in the 2 showers and bath I have to brake the wall behind the mixer to access it and replace it. 
Is it that the case? Can’t I just replace the old mixer with a new one?

I see what you saying. The property is not super hold. From what I saw at Bunnings, they are all pretty similar. As long I can find the same size ring and cartridge should not be a problem. To me seems so crazy that to replace a tap I need to gut the bathroom

Hello team, 

I think I have a plan. I have purchased the exact tap mixer I have installed (45$) I’ll use it to make sure that the  mixer I’ll purchase fit the one I currently have. With all the pieces in my hand should be a pretty straight forward process. Any thoughts?

My best advice is to keep your docket and be very careful when replacing and testing the parts. You don't want to damage them just in case you need to return or exchange them. Please keep us updated with your progress, we look forward to seeing your new shower fittings installed.
