How Hard Is It to Replace Your Own Bathroom Fixtures?

You’re staring at that outdated faucet or that toilet that runs every twenty minutes, wondering if you can handle the swap yourself or if you need to call someone. It’s a fair question. The Denver plumbing service pros at Bell Plumbing, Heating, Cooling & Electrical get asked this constantly by homeowners trying to figure out where the line is between a Saturday afternoon project and a job for a licensed plumber.

The honest answer: it depends on which fixture you’re replacing. Some swaps are genuinely simple. Others look simple until you’re three hours in with the water shut off and no idea how to reconnect the supply line.

Here’s the difficulty level for each one.

Easy: Showerheads and Tub Spouts

These are about as low-risk as bathroom work gets.

• Most showerheads thread on and off by hand or with a wrench
• Tub spouts either slide on or screw on, depending on the style
• If you can identify which type you have, you can usually handle it yourself

Usually Manageable: Faucets

Replacing a bathroom sink faucet is one of the more approachable projects out there, as long as a few things line up:

• Supply lines are in decent shape
• Connections aren’t corroded
• You’ve got a wrench, some plumber’s tape, and patience

Where it gets tricky: older Denver homes often have supply valves that haven’t been touched in decades. They can seize, crack, or leak the moment you try to shut them off. What should’ve been a 30-minute job turns into something bigger fast.

Moderate, With Real Risk: Toilets

Toilet installation looks straightforward on paper. Remove old toilet, set new wax ring, bolt down new toilet, done.

In practice, a poorly seated wax ring or a cracked flange leads to slow leaks that damage your subfloor long before you’d ever notice a puddle. If your existing toilet has been in place for 15-plus years, there’s also a good chance the shutoff valve underneath hasn’t been exercised in just as long.

That’s worth checking before you disconnect the old one, not after. If you’re not confident about sealing the base correctly, Bell’s toilet repair and installation service takes that risk off the table.

Harder Than It Looks: Vanities and Sink Basins

Swapping a full vanity means dealing with:

• Disconnecting the drain and supply lines
• A wall or floor that’s been hidden by the old unit for years
• Possible water damage underneath
• Mismatched plumbing rough-in measurements
• A drain that doesn’t line up with your new sink’s location

This is where a lot of confident DIYers end up calling for help partway through.

Plan on Professional Help: Shower Valves and Trim Kits

Shower valves are typically installed inside the wall, which means opening up drywall or tile just to reach them. Get the connection wrong and you won’t see the leak until it’s already damaged the wall or the floor below.

If your valve is failing or you’re upgrading to a new shower system, Bell’s plumbing team handles this regularly, usually with minimal wall repair needed afterward.

The Real Question: What’s Behind the Wall?

Fixture difficulty isn’t just about the fixture. It’s about what’s connected to it. A faucet swap in a house with newer supply lines is a breeze. That same swap in a 1970s Denver home with original galvanized piping can turn into a much bigger job the moment you touch anything.

Before committing to a weekend project, check the age of your home’s plumbing and the condition of the shutoff valves. Anything corroded, discolored, or original to the house is a sign to have a professional take a look first.
