How to Choose a Sink Tap: Mixer, Pillar or Sensor

1. Three Sink Tap Types, One Confusing Aisle

Standing in the plumbing aisle at the hardware store, or scrolling an online store late at night, you meet three names pillar, mixer, sensor and almost no plain explanation of which one belongs on your sink. Pick wrong and you find out too late: your basin has the wrong number of holes, your gravity-fed tank can't push enough pressure, or your water bill quietly creeps up.

This guide shows you how to choose a sink tap the way a renovator actually decides — by holes, water pressure, budget, water savings, finish and upkeep. At Big Bath, we've fitted all three types across our nine Malaysian branches for over 40 years, so this is the advice we give customers in store. By the end you'll know which tap fits your kitchen or bathroom, and why. The short video below shows how to tell tap types apart before we go deeper.

2. What Is a Pillar Tap?

Quick Answer: A pillar tap is the classic design with two separate taps, one for hot and one for cold, each sitting on its own hole in the basin. You mix the temperature in the bowl, not inside the tap. In Malaysia's warm climate, many homes simply run a single cold pillar tap.

Pillar taps are the oldest of the sink tap types and still the cheapest. Each tap feeds one supply line, so they are simple to fit and easy to replace one side at a time. They also work well on low water pressure, which suits older landed homes and gravity-fed tank systems.

The catch is the basin. Pillar taps need two tap holes, so switching to a single-hole mixer later means changing the basin or fitting a cover plate. There's also a local quirk worth knowing: across much of Malaysia and the region, pipe water sits at a comfortable 25–30°C all year, so plenty of households never plumb hot water to the basin at all. A single cold pillar tap does the job. If your bathroom leans traditional, browse our mixer and pillar sink taps with crosshead or lever handles.

3. What Is a Mixer Tap?

Quick Answer: A mixer tap blends hot and cold water inside one body and sends it out through a single spout, usually controlled by one lever. It needs just one hole in the sink, gives instant temperature control, and is the default choice in most modern Malaysian kitchens and bathrooms.

Inside a single-lever mixer, a ceramic disc cartridge sets both flow and temperature. Lift the lever for more water; swing it left or right for hotter or cooler. That one-handed control is why mixers dominate new builds. They need only one tap hole, so a basin looks clean and uncluttered, and they pair with almost any modern sink.

The main thing to check is pressure. Many mixers need a minimum flow to blend hot and cold properly, so on a low-pressure gravity tank you should choose a model rated for low pressure or fit a pump. Prices stretch from around RM120 for an entry-level basin mixer to RM500 and beyond for a designer kitchen unit, so there's a tier for every budget. See the range of single-lever wash basin mixers before you commit.

4. What Is a Sensor Tap?

Quick Answer: A sensor tap is touchless. An infrared sensor detects your hands and runs the water only while they are there, then shuts off on its own. That makes it the most hygienic and water-efficient of the sink tap types, and it is moving from airport washrooms into Malaysian family bathrooms and kitchens.

No handle means no germs passed from dirty hands to a tap and back, which helps when you're handling raw chicken or the kids forget to turn the water off. Because flow stops the instant hands leave, a sensor tap trims the litres wasted while you soap up or scrub a pot.

Most sensor taps run on batteries or mains power, and you can usually set the flow and run-time once, then forget it. The trade-offs are price and power. Sensor taps start higher, roughly RM200 and climbing past RM800, and you'll eventually swap batteries or wire in a transformer. For busy households that value hygiene and lower bills, explore the touchless and intelligent-digital options in our taps and fittings range.

5. Mixer vs Pillar vs Sensor: Side by Side

Quick Answer: Pillar taps win on price and low-pressure tolerance, mixer taps win on everyday convenience, and sensor taps win on hygiene and water savings. The right sink tap type depends on your basin holes, your water pressure, and how much touch-free use matters to you.

6. How to Choose the Right Sink Tap

Quick Answer: To choose the right sink tap, start with three fixed facts about your sink: how many tap holes it has, what water pressure you get, and which room it's for. Style and finish come after. Those three checks rule out most wrong buys before you fall for a look.

Work through them in order:

• Count the holes. One hole points to a mixer or sensor tap; two holes point to pillar taps (or a three-hole set on a vanity).
• Check your pressure. Gravity-fed tanks in older homes run low. If that's you, pick a low-pressure-rated mixer or stay with pillar taps.
• Match the room. Kitchens want a tall or pull-out spout for filling pots; bathroom basins want a shorter spout to avoid splashing.
• Mind the spout height. Tall vessel basins need a high-neck tap; shallow basins need a low one.

Once those four are settled, the finish and shape are mostly personal taste. For a basin specifically, compare shapes and heights across our wash basin mixers before deciding.

7. What Each Tap Type Costs Over 5 Years

Quick Answer: Upfront price isn't the whole story. A cheap tap that runs more water can cost more over time once the bill is added. The table below shows an illustrative five-year cost for one basin tap by type, using Selangor's domestic water rates of RM0.65 to RM3.51 per cubic metre.

An aerated mixer or a sensor tap costs more on day one but can claw it back through lower water use — most clearly on a heavily used family basin.

8. Flow Rates & Water Savings Compared

Quick Answer: Water savings come down to flow rate the litres a tap pushes per minute and whether it shuts off on its own. Standard taps run fast and free; aerated mixers cut flow by mixing in air; sensor taps add automatic shut-off. Together those features can roughly halve basin water use.

Look for an aerator and a water-efficiency label. On a basin used many times a day, the saved litres add up fast.

9. Finishes & Durability by Tap Type

Quick Answer: Finish is about looks and upkeep, not just colour. Chrome is cheap and easy to clean but shows water spots; matte black hides marks but shows limescale; brushed nickel sits between the two. Under the finish, a solid brass body lasts longest in Malaysia's humid, sometimes hard water.

Whatever the finish, check that the body is solid brass or stainless steel. Both resist the corrosion that humid, hard-water homes bring on.

10. Installing & Maintaining Your Tap

Quick Answer: Most sink taps fit in under an hour if the hole count matches. The basics are simple: shut off the supply, fit the tap and gasket, connect the hoses, then check for leaks. Upkeep is mostly cleaning the aerator and wiping the finish, while going easy on harsh chemicals.

The fitting itself follows four steps:

1. Shut off the water. Close the under-sink valves and open the tap to drain the pressure.
2. Remove the old tap. Undo the supply hoses and the mounting nut, lift the tap out, then clean the surface.
3. Fit the new tap. Seat the gasket, drop the tap into the hole, and tighten the nut from below until snug.
4. Connect and test. Attach the hot and cold hoses, turn the water back on, and check every joint for leaks.

After that, clean the aerator every few months and skip abrasive cleaners. For a sensor tap, check the batteries once or twice a year. If you'd rather not DIY, the team at any Big Bath branch can fit it for you.

11. Which Sink Tap Should You Buy?

So, which of the sink tap types is right for you? If your basin has two holes or you're on low pressure, a pillar tap is the simple, cheap answer. If you want everyday convenience in a modern home, a single-lever mixer is the safe default. And if hygiene and a lower water bill matter most a busy family kitchen, a clinic, a shared bathroom a sensor tap earns its higher price.

Count your holes, check your pressure, set a budget, then pick the finish you'll enjoy cleaning. Do that and you'll buy once, not twice.

12. Frequently Asked Questions

1. What is the difference between a pillar tap and a mixer tap?

A pillar tap has two separate outlets one for hot, one for cold so you mix the water in the basin. A mixer tap blends both inside one body and pours from a single spout with one lever. Pillar taps need two holes; mixer taps need one.

2. Which sink tap type saves the most water?

A sensor tap usually saves the most, because it runs only while your hands are under it and then shuts off. An aerated mixer is the next best, cutting flow by mixing air into the stream. A standard pillar or mixer tap with no aerator uses the most.

3. Do sensor taps work during a power cut?

Battery-powered sensor taps keep working during a power cut, since they don't rely on mains electricity. Mains-powered models stop unless they have a battery backup. For homes with frequent outages, a battery or battery-backup sensor tap is the safer choice.

4. Can I replace a pillar tap with a mixer tap?

Yes, but it takes a little work. A mixer needs a single hole and both hot and cold supplies, while pillar taps use two holes. You may need a cover plate for the spare hole, or a basin swap. If you're unsure, ask a plumber to check first.

5. Which tap is best for low water pressure in Malaysia?

Pillar taps cope best with low pressure, which is why they suit older gravity-fed homes. If you prefer a mixer, choose one rated for low pressure or add a small pump. Check the minimum pressure on the box before you buy.
