Pros and Cons of Upgrading to Touchless Plumbing Fixtures

Let’s be honest for a second. Ten years ago, the only place you saw a touchless faucet was in an airport bathroom or a fancy restaurant. And half the time, they didn’t even work. You would stand there waving your hands like a magician, hoping for a drop of water, and end up wiping soap on your pants.

But things have changed.

Since 2020, the world has become obsessed with hygiene. We are all a little more conscious of what we touch. Suddenly, the idea of turning on a faucet after handling raw chicken and then touching that same handle again with clean hands, seems a little backwards, doesn’t it?

In Southern California, where we love our smart homes and modern design, touchless plumbing fixtures are exploding in popularity. We are seeing them in custom homes in Newport Beach, remodeled condos in downtown San Diego, and family homes in Riverside.

But are they actually worth the money? Or are they just another gadget that is going to break in two years?

As a plumbing team that has been serving this region since 1984, we have installed thousands of these units. We have seen the good, the bad, and the ugly. If you are on the fence about upgrading, here is the honest, no-nonsense breakdown of the pros and cons.

What Exactly Are We Talking About?

When we say “touchless,” we aren’t just talking about the sink. The technology has spread to:

• Kitchen Faucets: Motion sensors (usually on the side or top) turn the water on.
• Bathroom Faucets: Standard infrared sensors.
• Toilets: Wave-to-flush technology (no more kicking the handle).
• Soap Dispensers: Built-in countertop units.

The technology is simple: An infrared sensor or a capacitance field detects the electricity in your body or motion and opens a solenoid valve. Water flows. You walk away. Water stops.

The Pros: Why People Love Them

There is a reason these are flying off the shelves. When they work, they are fantastic.

1. The “Raw Chicken” Factor (Hygiene)

This is the number one selling point. Picture this: You are making tacos. You have raw ground beef or chicken juice on your fingers. You need to wash your hands.

• Old Way: You grab the faucet handle with your dirty hand. You wash your hands. Then you grab the now dirty handle to turn it off. You just re-contaminated yourself.
• New Way: You wave your forearm past the sensor. Water comes on. You wash. You leave. The handle stays spotless.
  It stops the spread of germs like E. coli and Salmonella in the kitchen. For families with young kids who bring home every school germ imaginable, this is a game-changer.

2. Water Conservation (The SoCal Reality)

In Southern California, water is expensive. We are constantly in and out of drought restrictions.

Touchless faucets are naturally stingy. They don’t let the water run while you are brushing your teeth. They shut off the second you pull your hands away.

• The Statistic: According to the EPA, leaving the tap running while brushing teeth can waste up to 4 gallons of water per minute. A sensor faucet eliminates this waste entirely, potentially saving the average family thousands of gallons per year.

3. Accessibility for Seniors

We do a lot of “Aging in Place” remodels. For someone with severe arthritis, Parkinson’s, or limited grip strength, twisting a tight knob is painful. A touchless fixture gives them independence. They don’t have to grip anything; they just have to be near it.

4. The “Cool” Factor

Let’s admit it, it looks cool. Having a sleek, handle-free kitchen island impresses guests. It makes the home feel futuristic and high-end. If you are building a custom home to sell, these are the details buyers look for.

The Cons: The Stuff Nobody Tells You

It isn’t all sunshine and rainbows. There are real downsides to adding electronics to a plumbing system.

1. The Power Problem

Regular faucets use gravity and pressure. They never stop working. Touchless faucets need electricity.

• Battery Operated: Most residential units run on AA batteries. They last about a year. But when they die, they die. Usually when you are in a rush.
• Hardwired: In New Construction, we can plug them into an outlet under the sink (AC adapter). This is the best way, but it requires an electrician to install an outlet inside your cabinet.

2. The “Ghost” Activation

Sensors can be sensitive.

• Your cat jumps on the counter? The water turns on.
• You are washing a big pot and your shoulder brushes the sensor? The water turns off right when you need it.
• A shadow from the window hits it wrong? Ghost water.
  Newer models are better at ignoring false alarms, but it still happens.

3. Temperature Frustration

This is the big one. With a manual faucet, you push the handle left for hot and right for cold.

With a touchless faucet, the handle usually stays in one “preset” position. If you want to change from cold drinking water to hot dish-washing water, you usually have to touch the handle anyway to adjust the mix. Some high-end voice-activated ones solve this (“Alexa, dispense hot water”), but they are very pricey.

Comparison: Is It Worth It?

Here is a quick cheat sheet to help you decide.

The Southern California Hard Water Warning

This is something most blogs won’t tell you because they are written for a general audience.

Southern California has very hard water.

Our water is full of calcium and minerals. When water dries on a surface, it leaves a white crust (scale).

• The Risk: If that white scale builds up over the tiny sensor window (usually a little black glass circle), the sensor goes blind. It stops seeing your hands.
• The Fix: You have to gently wipe the sensor with vinegar or a mild cleaner regularly. If you ignore it, the faucet will stop working.

New Construction vs. Retrofit

If you are building a new home, we highly recommend planning for touchless fixtures now, even if you don’t install them yet.

Why?

Because of the power.

If you are in the “Rough-In” phase of building, you can ask your electrician to install a power outlet inside the vanity cabinet or under the kitchen sink.

If you do this, you can install a hardwired touchless faucet later. You will never have to change batteries.

If you are retrofitting an old house, you are likely stuck with battery packs. It works, but crawling under the sink once a year to change 6 AA batteries is a chore most people hate.

Who Should Buy This?

You SHOULD upgrade if:

• You cook a lot (raw meat/baking).
• You have young kids who can’t reach the handles or forget to turn water off.
• You have an elderly family member living with you.
• You are remodeling a “Forever Home” and want the latest tech.

You should SKIP it if:

• You are on a tight budget.
• You get frustrated easily by technology.
• You have cats that walk on the counters (seriously, they love the moving water).

Maintenance Tips for Touchless Owners

If you already have one, or you are about to buy one, here is how to keep it alive:

1. Clean the Sensor: Use a soft cloth. Do not use abrasive scrubbers (like steel wool) on the sensor window. If you scratch it, it breaks.
2. Change Batteries Proactively: Don’t wait for it to die. Change them every daylight savings time (just like your smoke detectors).
3. Keep the Under-Sink Area Clear: The control box is under there. If you shove a bunch of cleaning supplies against it, you might knock a wire loose.
4. Know the Manual Override: almost every touchless faucet has a way to bypass the sensor and work manually. Learn how to do this before the battery dies so you aren’t stuck without water.

The Verdict

Touchless technology is here to stay. It isn’t a fad. The hygiene benefits alone make it a winner for most families.

However, it is an investment. It requires a mindset shift. You are trading simplicity for capability.

Frequently Asked Questions

1. What happens if the power goes out?

If you have a battery-powered unit, nothing happens, it keeps working! If you have a plug-in (AC adapter) unit, it will stop working unless it has a battery backup. Most high-quality plug-in models come with a battery backup case for exactly this reason. Always check before you buy.

2. Are they difficult to install?

They are harder than a regular faucet. You have more parts: a control box, a battery pack, and data cables. It usually takes a professional plumber about an hour to install one correctly. If you try to DIY it and pinch a data wire, the whole unit is trash.

3. Can I adjust the water temperature without touching it?

On most standard touchless models, no. You set the handle to a “warm” mix, and the sensor just turns that mix on and off. If you want hot water, you have to manually move the handle. However, expensive “smart” faucets (like Moen or Delta) allow you to ask for specific temperatures via voice command.

4. Do they really save money?

They save water, which saves money. But because the unit costs $300-$500 more upfront, it will take a long time to “pay for itself” strictly through water bill savings. The value is really in the hygiene and convenience, not just the financial return.

5. How long do the batteries last?

In a typical family home (kitchen use), a set of AA batteries lasts about 12 to 18 months. In a guest bathroom that is rarely used, they can last 2 years. Most faucets have a blinking LED light that warns you when the battery is getting low (usually a red flash).

6. Can I install one in my bathroom?

Yes! Bathroom touchless faucets are great for keeping the vanity clean. No more wet hands dripping water all over the counter while reaching for the handles. They keep the bathroom looking spotless much longer.
