Getting new shower walls?
Consider replacing the shower fixture too.
You got tired of the old shower walls, and have finally gotten the guts to replace the dated materials with a new, up-to-date style. That is great news; you will enjoy the decision once the home improvement is completed. But this may be a perfect opportunity to do a little more.
Consider replacing the shower plumbing fixture also, they will not be a better time to replace the plumbing located behind the walls. This just makes sense, but too often it is overlooked or not considered an important change.
Changing the plumbing is particularly important if they are no longer making the parts for your existing unit. Imagine needing to replace parts that are no longer being produced and getting to the plumbing fixture now requires tearing into the new shower walls. Not good.
So if you are replacing the shower walls, at least consider replacing the plumbing fixtures at the same time.
