It seems like every shower has its own unique way of controlling water temperature and pressure. Of all the showers I’ve ever used, no two of which have ever been alike, I like my controls the least. Plus the faucet has started dripping lately.

Is this likely to be something I can replace on my own, without a plumber? To me, that means: Can I likely do this without damaging the wall, without having to mess with pipes, and without needing to do anything involving words like “hacksaw”, “weld”, or “plumbing torch”?

Basically I believe in my ability to buy a faucet and control thingie from Home Depot; to use screwdrivers, allen wrenches, pliers, and regular wrenches; to use things like plumbing tape, lubricants, and caulk; and to remember to turn the water off to the house.

Would a project like this likely require anything more complex than that? I tend to prefer shower controls that have separate knobs for hot and cold, but I figure going from a one-knob setup to a two-knob setup is definitely going to require reconfiguring the plumbing. Should sticking with a one-knob solution be okay?

I don’t know if it matters but I live in Florida in the US, and this place was built in the 1980s. I doubt this matters, but my current controls work by turning the larger knob left or right for temperature, and the smaller knob for pressure.

My place does have some annoyances - like the front door is an uncommon size that’s difficult to find replacements for at places like Home Depot. Is there any chance of me running into issues like that when it comes to things like the size of the pipe openings?

Thanks for any insight.

Edit: Thanks for all the replies. It’s pretty clear now that this is something that could very easily end up a lot more involved and time consuming and property damaging than I’m comfortable with.

    Go on google or Amazon and search for shower valves, you’ll find pictures of what’s inside the wall behind the chrome plate you got there… seeing images will give you a better idea of what to expect than anything anyone can describe.

    After that, go take the knob off your shower valve (probably the center cap pries out, you take out a screw, and it pulls off), then take off that chrome ring (Allen screw on bottom, or it might just get pried off carefully or unscrew the whole thing, they vary). Have a look… that’ll tell you what your specific type of valve is and if you can do this without making a big ass hole in a wall…

    Then figure out what’s on the other side of the wall the valve is on… if it’s a closet, maybe a big ass hole in the wall is ok? A big ass hole in the wall of the shower will involve tile. I’m thinking based on your description that you should 100% not fuck with tile. You’ll get into all manner of special tools, special skills, etc. real quick with tile :) a hole in drywall in someone’s closet might be a homeowner kinda deal though tbh.

    Those three things are hopefully enough to answer your own questions, because the real “no bullshit” answer is that it depends… pex, copper, iron, delta, thermo, yadda yadda yadda… The shit inside the wall is as varied as the shit on the outside…

    I could do this myself, but I wouldn’t… sink, toilet, ice maker, leak in the crawlspace, move the hose bib outside to the complete other side of the house, replace the water heater, add an expandion tank, all that shit is an immediate “fuck no im not paying soneone to do that, ill do it”, but a shower valve is a hard no :)

    Have a look by all means, no harm in checking it out, but I wouldn’t be too optimistic in your shoes.
