Change shower from seperate hot and cold handles to a single unit
We currently have older plumbing in the shower and have replaced the hot and cold handles twice now. They break off easily and we now want to convert from the 2 seperate handles to one single unit that turns on the water and adjusts the temperature. We have a limited budget and want to know how much it will cost to redo our shower plumbing to this configuration. Does anyone have a ballpark idea as we plan to take down all the tile and replace the tub as well but need to know how much we will end up spending on the plumbing issue.
