How to Choose Bathroom Fittings for a Delhi Home

Start with hard water, because it decides most of this

Delhi and NCR water carries a lot of dissolved mineral. It comes out of solution wherever water evaporates or is heated, which means on every tap, every shower face and inside every cartridge. This is not a maintenance detail — it is the main thing that determines how long a fitting lasts here.

• Prefer a ceramic disc cartridge, and prefer a make whose cartridges are widely stocked. Ceramic discs handle grit better than a rubber washer over time. But the cartridge is a consumable in Delhi water, so the practical question is not which is best in a showroom — it is whether a plumber can get that exact part in two years. Unbranded or heavily discounted mixers frequently fail this test, and then a small fault becomes a whole new fitting.
• Choose a shower head with rubber nozzles you can rub clean. The flexible silicone nubs let you push the scale out with a thumb in ten seconds. A shower face with fine drilled metal holes will block, will need soaking in vinegar repeatedly, and will eventually spray sideways for good.
• Avoid deeply textured, engraved or complicated shapes. Scale collects in every groove and stays there. Simple, smooth forms wipe clean; ornate ones become a weekly chore.
• Be realistic about matt black, brushed gold and coloured finishes. They look excellent and they show hard-water marks and cleaning damage more readily than chrome, which is dull-looking but genuinely the most forgiving finish in this water. If you want a coloured finish, accept that it needs wiping dry after use.
• Solid brass bodies with a proper plated finish outlast light alloy ones, which corrode from the inside where the plating is thinnest. Weight in the hand is a rough but real indicator.
• If you can, treat the water rather than the symptoms. A softening or anti-scale arrangement on the supply protects the geyser, the fittings and the machines together. Our hard water tips cover the day-to-day side.

Concealed or exposed plumbing?

This is the biggest decision, it is taken before tiling, and it cannot be reversed later without breaking the wall. Neither answer is wrong; they trade appearance against serviceability.

Concealed means the working body of the mixer or diverter sits inside the wall and only the handle and spout show. It looks clean and modern, it is easy to keep free of scale on the outside, and it is what most new Delhi bathrooms use.

Exposed means the body is on the surface. It looks more utilitarian, but every part is reachable with a spanner, and replacing it later is a half-hour job with no tiling.

What actually matters when choosing between them:

• Concealed fittings are only as good as the body inside the wall. The visible handle can be replaced; the body cannot, not without breaking tiles. Spend your money on the concealed part and save it on the trim if you have to choose.
• Insist on a serviceable concealed body. Good concealed valves are designed so the cartridge can be pulled out from the front, through the wall plate, without opening the wall. Ask specifically whether the model you are buying allows that. It is the single most useful question in this entire guide.
• Concealed pipework must be pressure-tested before tiling. The line is charged with water or air and held under pressure to prove every joint holds. If a builder or contractor skips this, a joint that weeps will be found by the neighbour below, months later, through his ceiling.
• Photograph the walls before tiling. Take clear pictures of every pipe run with a tape measure in the frame. In three years, when someone wants to hang a mirror or fix a cabinet, those photos are what stop a drill going through a concealed line — which is a genuinely expensive accident.
• Exposed is the sensible choice in a rental, a servant bathroom, a utility area or a house you plan to redo soon. There is no shame in it, and repairs cost a fraction.
• Wall-hung WCs and concealed cisterns follow the same logic. They look excellent and free up floor space, but the cistern and its flush valve live inside a wall or a false wall. Only choose one with a proper access panel behind the flush plate, and confirm the inlet and flush valves inside are a serviceable, commonly available type.

Match the fittings to the water pressure you actually have

A great many disappointing Delhi bathrooms are the result of fittings chosen for pressure the flat does not have. Most flats here are fed by gravity from an overhead tank, and the pressure at your shower is decided almost entirely by the height of that tank above it.

• Top-floor flats have the least pressure, because the tank is barely above them. If you are on the top floor, be cautious with any fitting that needs pressure to perform.
• Rain showers and large overhead shower heads need real pressure and volume. On a gravity feed they often deliver a disappointing sprinkle. A smaller head with a good spray pattern will feel far better than a large one that is starved.
• Body jets and multi-function shower panels need more flow than a typical Delhi flat provides. Be honest about this before buying.
• Thermostatic mixers need reasonably balanced hot and cold pressure to hold a temperature. If your cold comes from the tank and the hot from a geyser fed differently, check the arrangement with your plumber before choosing one.
• A pressure-boosting pump is an option, not a given. It can transform a top-floor shower, but it needs space, power and correct installation, and it must not be allowed to draw directly on a shared line.
• Test what you have before you buy. Time how long your current shower takes to fill a bucket. That tells you more about what will work than any showroom demonstration. Our low water pressure guide covers improving what you have.

What to prioritise, and what to save on

If the budget will not stretch to everything, this is the order that people who have lived with the results would choose.

Spend on these:

• Waterproofing and floor slope, before anything visible. No fitting matters if the floor leaks into the flat below. This is invisible, unglamorous and the single most consequential thing in the room — our bathroom waterproofing guide explains what a proper job includes.
• Concealed bodies and anything buried in a wall. Cost of failure is enormous relative to the part.
• The drainage: floor trap, waste pipes, and their fall. An anti-odour floor trap and properly sloped waste pipes prevent the two most persistent bathroom complaints there are.
• The mixer you use every day, particularly the shower mixer. This gets operated thousands of times a year, and a cheap cartridge shows it.

Save on these without regret:

• Accessories. Towel rails, soap dishes, robe hooks and paper holders do a simple job. Mid-range stainless or good chrome is fine.
• The health faucet. It is a consumable in Delhi water and will need replacing regardless. Buy a decent ordinary one rather than a designer version.
• Anything decorative in a bathroom guests never enter.
• Very large or complex shower systems that your pressure cannot support anyway.

And a few practical checks before you buy anything: confirm the fitting matches your existing pipe centres if you are replacing rather than rebuilding; check the spout reach actually clears the basin, which is a surprisingly common mistake; ask whether spares are stocked locally; keep the bills and warranty cards together somewhere you will find them; and buy all the fittings for one bathroom in the same finish family, because chrome from different makes rarely matches exactly.

Buy the fittings before the plumbing work starts

This is the practical failure that causes the most rework in Delhi bathrooms, and it is entirely avoidable.

• The plumber needs the actual fittings, or at least the exact models, before roughing in. Pipe centres, wall thickness allowance, the depth a concealed body sits at, the height of a shower outlet, and the position of a WC inlet all depend on the specific product. Guessing means chipping tiles later.
• Decide the layout before any wall is cut. Where the WC sits, which side the shower is on, whether the basin is counter-top or wall-hung, whether there is a washing machine point. Moving any of these afterwards means new plumbing points — our new plumbing point guide covers what that involves.
• Check the concealed body depth against your tile and wall build-up. Set too deep and the handle will not reach; too shallow and the plate will not sit flat. This is one of the commonest installation errors.
• Keep every spare part, allen key, aerator and instruction sheet that comes in the box, in one labelled bag. In three years, that bag is what saves a fitting from being replaced.
• Order a spare cartridge for each concealed valve at the time of purchase, while the model is definitely current. It is a small item and it removes the worst failure mode in this entire guide.
