I'm tackling some home renovations, including two bathrooms, and I'm considering my plumbing options. Right now, my entire house is set up with copper pipes, which have worked well so far. However, I'm thinking of ditching the copper at the connection points for things like showers and vanities and switching to PEX. It seems easier to handle, more forgiving, and potentially cheaper overall (aside from the initial cost of tools). Before I invest in tools and supplies for multiple projects, I'd love to hear your thoughts on whether going from copper to PEX is a smart move. Thanks in advance!

While every added connection can increase the chances of leaks, all materials have their quirks. I’ve used PEX extensively and haven’t dealt with leaks, and I find it way simpler when doing remodels. If you’re replacing everything, you’ll appreciate how much easier PEX is, especially in tight spaces.
I think it depends on the job. For visible areas, I prefer good old copper due to its durability. But for hidden spots and flexibility, PEX is fantastic and lets you add features like outdoor water lines easily. Just make sure you’re using quality connectors to minimize leak risks!
If your existing copper is in good shape, I’d suggest leaving it and only replacing what needs to go with PEX. It maintains a solid connection with less chance of leaks.
I was thinking of replacement all around, since I'm updating the fixtures too. If I replace, it’s PEX or new copper, and I’m weighing the effort of soldering versus switching to PEX.

For sure! Using quality brass fittings with PEX seems like the best route. Plus, being able to push it through can save tons of time!
