Your kitchen or bathroom mixer has started dripping, the handle feels loose, or the old chrome is pitting from years of sea air. Replacing it is one of the most straightforward plumbing jobs we do here in Sanur – but choosing the right unit and dealing with the supply lines underneath can trip you up. Here is what to look for when buying, how the swap actually goes, and what to check before anyone starts unscrewing things.
Which Mixer Tap Suits Your Villa
Start with the body material. In Sanur's humid, salt-laden air a zinc-alloy tap will start to pit within a year or two. You want a solid brass body with a quality PVD or chrome finish. If the tap sits near an outdoor kitchen or pool deck, ask specifically for marine-grade or 304 stainless components; standard chrome will not hold up against daily splashes of seawater mist.
A single-lever (monobloc) mixer is generally easier to maintain than a two-handle model because there are fewer rubber seals exposed to PDAM water, which can carry slight acidity depending on the day. The internal ceramic-disc cartridge typically outlasts older rubber-washer designs by several times over.
Before you buy, measure three things: the distance between your hot and cold wall outlets (or the single-inlet position), the height from the basin rim to the outlet, and whether the existing mixer mounts from above the deck or below it. A photo of the current setup, taken from directly above, saves a lot of guesswork.
- Brass body – avoid 'stainless' taps that are actually plated mild steel
- Ceramic-disc cartridge for longer service life
- Check inlet spacing: 150 mm is the Bali standard, but older villas sometimes use 120 mm
- For poolside or open-air kitchens: specify marine-grade hardware
Where to Buy a Mixer in Bali
The quickest option is one of the plumbing-supply shops along Jl. Raya Sanur or the cluster around Jl. Gatot Subroto in Denpasar. You can walk in, compare finishes under natural light, and pick up the unit the same day. Bring a photo of your existing tap so the shopkeeper can confirm the inlet pattern matches.
Online marketplaces like Tokopedia or Shopee offer a wider range and often lower sticker prices, but delivery can take two to four days and returns on a sealed box are a hassle if you discover the inlet spacing is wrong. If you go this route, order at least three working days before the planned install date.
Whichever channel you choose, ask the seller to confirm the body is brass (they should be able to weigh it – brass feels noticeably heavier than zinc alloy) and that the cartridge is replaceable rather than welded into the body.
Send a couple of photos of your current tap and under-sink area on WhatsApp and we will tell you exactly what needs replacing and quote the job before anyone lifts a wrench.
How We Replace It – Step by Step
First we shut off the isolation valve under the basin or the main stopcock for that branch line, then open the tap fully to drain any residual pressure in the pipe. Only once there is no water coming out do we start disconnecting.
The old mixer comes off from above the deck: undo the mounting nut, lift the unit, and pull the braided supply hoses free from the wall outlets. At this point we inspect the threads on both the wall fittings and the underside of the basin for corrosion or mineral build-up and clean them back with a wire brush.
A new gasket goes on the washer face, the new mixer is seated and tightened hand-plus-a-quarter-turn (overtightening cracks ceramic basins), and fresh braided flexible hoses are connected to both the mixer inlets and the wall outlets. We use stainless-steel-braided hoses with rubber-lined cores rather than the thin plastic ones bundled with budget taps.
Water is turned back on slowly. We check every joint – both hose connections, the base of the mixer, and the area where it meets the basin – for any seepage. Then we run hot, cold, and mixed flow for about two minutes to confirm smooth operation before we pack up.
- Have the isolation valve location identified before we arrive
- Clear the under-sink cabinet so we can work comfortably
- If the basin is porcelain or glass, keep the area dry around the mounting hole
Old Supply Lines: The Hidden Problem
Many Sanur villas built in the 1990s or early 2000s still have their original copper pipes or first-generation braided hoses running from the main line to each tap. Years of humidity, salt air, and variable PDAM pressure take a toll. A hose that looks fine on the outside can have a split inner liner waiting to burst during a rainy-season pressure spike.
Because of this, when we swap a mixer we almost always replace both supply lines at the same time. It adds ten minutes to the job but removes a common source of slow drips that come back three months later.
The trickier issue is the wall outlet itself. If the thread is stripped, the fitting has corroded through, or the pipe behind the tile is soft, we may need to fit a repair sleeve or cut out a short section and re-thread it. That is extra work, and we will flag it before touching anything so you are not surprised by the scope.
If you see green-blue corrosion, flaking paint on the pipe, or the metal crumbles under your fingers, stop working on it and call us. Forcing a corroded fitting can crack the pipe behind the plaster and turn a simple tap change into a wet-wall repair.
What Does the Job Cost?
There is no single rate because every villa is different. The final quote depends on the type and size of the mixer, whether new supply lines are needed, the condition of the wall outlets, and how accessible the under-sink area is (a tight cabinet with old grout around the deck takes longer than an open stainless-steel kitchen).
The simplest way to get a number: take two or three clear photos – one straight-on of the current tap, one showing the inlet spacing, and one of the under-sink space – and send them over on WhatsApp. We look at what we are dealing with, tell you what needs replacing alongside the mixer, and give you a fixed price before anyone picks up a wrench. You pay once the job is done and you have run the water yourself to confirm there are no leaks.
Questions
Can I just buy any mixer online and fit it myself?
You can, but the most common mistake is inlet-spacing mismatch or overtightening that cracks the basin. If your wall outlets are original and possibly corroded, a professional check saves you from a burst pipe behind the tile. Send us a photo first and we will tell you honestly whether it is a straightforward DIY swap or something better left to someone with the right tools.
How often should I replace the cartridge inside my mixer?
With PDAM water and the occasional well-water top-up, a quality ceramic-disc cartridge typically lasts three to five years in normal use. If the flow starts feeling weak, the handle gets stiff, or you notice a slow drip even when fully closed, the cartridge seals are likely wearing. Replacing just the cartridge is much cheaper than a whole new tap – send us a photo of the model number on the body and we can advise.
My outdoor kitchen tap has white crusty deposits around the base. Is that a problem?
That is mineral scale from hard water mixing with salt-air moisture – very common on Sanur pool decks and open kitchens. It looks ugly but is not structurally dangerous by itself. However, if the metal underneath is pitting or the finish is flaking, the tap is past its useful life and should be swapped for a marine-grade unit before the corrosion reaches the internal seals.
