Sourcing bathroom faucets and sanitary ware across borders means decoding a stack of overlapping terms: trade slang, engineering standards and factory shorthand. The same component can be called three different names depending on the market, and one misunderstood spec can turn a profitable order into a returns headache. This glossary defines 48 essential terms for B2B buyers, specifiers and importers. We have grouped them the way you actually work through a project — fixture types, handles and mounting, valves and internals, materials and finishes, performance and efficiency, and certifications plus trade terms — and added a live search so you can jump straight to the term you need.
Start with the fixture families. Knowing whether a project needs torneiras de lavatório, kitchen faucets or a full shower system determines the rest of the specification.
| Term | What it means & why it matters to B2B buyers |
|---|---|
| Basin faucet / Basin mixer | A faucet designed for hand-washing sinks. Mixers blend hot and cold in one spout; pillar taps keep them separate. Buyers often pair them with torneiras de lavatório from the same finish family for project consistency. |
| Kitchen faucet / Kitchen mixer | A taller, higher-flow faucet for sinks and prep areas. Look for pull-out or pull-down spray options and 360° swivel if you are sourcing for multi-bay or commercial kitchens. See FAAO’s kitchen faucets range. |
| Shower faucet / Shower mixer | Controls water temperature and flow to a shower head. Exposed mixers sit on the wall; concealed versions hide the valve behind the tile. Browse matching shower faucets for coordinated bathrooms. |
| Bathtub faucet / Tub filler | A dedicated spout that fills the bath. Freestanding fillers sit on the floor beside the tub; deck- or wall-mounted versions attach to the rim or surround. FAAO’s torneiras de banheira cover deck, wall and floor styles. |
| Conjunto de chuveiro oculto | The mixing valve is recessed into the wall, leaving only the trim plate, handle and outlet visible. It gives a clean look and is popular in hotels and high-end residential projects. View the concealed shower sets collection. |
| Exposed shower system | The valve body and pipework sit on the surface of the wall. Easier to retrofit and service than concealed systems, making it common in renovation and rental-property markets. |
| Shower column | A vertical rail assembly that combines a shower mixer, hand shower, hose and often an overhead rain head in one pre-assembled unit. It reduces on-site installation time. |
| Bidet faucet / Bidet spray | A small faucet or hand-held shattaf used for personal hygiene. Common in Middle Eastern, South Asian and European markets; verify local plumbing codes before specifying. |

| Term | What it means & why it matters to B2B buyers |
|---|---|
| Single-handle faucet | One lever controls both temperature and flow. Faster to operate and easier to clean; preferred in ADA-compliant and high-traffic commercial bathrooms. |
| Double-handle faucet | Separate hot and cold handles, often with a vintage or classical look. Common in traditional hospitality designs; confirm handle indexing and escutcheon spacing. |
| Centerset faucet | A 4-inch (102 mm) faucet with the spout and handles mounted on a shared base plate. Easy to install on standard pre-drilled basins. |
| Widespread faucet | Spout and handles are independent, usually spaced 8–16 inches apart. More flexible for custom vanities and premium residential specs. |
| Wall-mounted faucet | The body mounts on the wall above the basin or tub. Requires concealed rough-in valves and precise spout-to-basin alignment. |
| Deck-mounted faucet | Installed directly on the basin rim, countertop or tub deck. The most common mounting style for basin, kitchen and tub fillers. |
| Vessel faucet / High-rise basin faucet | A tall faucet designed to clear above-counter vessel sinks. The spout height must match the bowl rim to avoid splash. |
| Freestanding bathtub faucet | A floor-mounted column that feeds a freestanding tub. Heavy and stable base required; check floor fixing and supply rough-in before ordering. |
Internals decide reliability and service life. The image below shows a typical cartridge, aerator, hoses and seals layout.
| Term | What it means & why it matters to B2B buyers |
|---|---|
| Ceramic disc cartridge | Two polished ceramic discs slide against each other to open or close water flow. Drip-free, long life and the modern standard for single-lever mixers. |
| Compression valve | A rubber washer compresses against a valve seat. Cheaper but wears faster and is more likely to drip; still used in budget two-handle taps. |
| Thermostatic valve | Maintains a set outlet temperature even if inlet pressure or temperature fluctuates. Critical for safety in schools, hospitals and care homes. |
| Pressure-balancing valve | Adjusts the hot/cold mix to keep temperature stable when water pressure changes. Required by many North American plumbing codes. |
| Diverter valve | Switches flow between outlets, for example from tub spout to shower head or from fixed rain shower to hand shower. Specify how many ways it must divert. |
| Aerator | A screen and flow straightener fitted to the spout tip. It adds air, reduces splash and controls flow rate. Standard thread is M24x1 male or M22x1 female. |
| Flow restrictor | A fixed or removable device that limits flow to meet water-efficiency rules. Removable ones are useful when local codes differ between markets. |
| Angle valve / Stop valve | A small shut-off valve connecting the faucet inlet to the building’s supply pipe. Often sold separately; confirm thread type and handle style with the project plumber. |
Material and finish choices affect cost, lead time and which certifications are possible. Always cross-check the quoted material against the destination market rules.
| Term | What it means & why it matters to B2B buyers |
|---|---|
| Brass (H59 / H62 / C37700) | The most common faucet body material. H62 has higher copper content and better corrosion resistance; C37700 is a lead-free forging brass common in North America. |
| Lead-free brass / DZR | Dezincification-resistant brass, such as CW602N or C46500, resists corrosion in aggressive waters. Required for drinking-water approvals in the EU, UK and North America. |
| Zinc alloy (Zamak) | A lower-cost die-cast material used for handles, decorative covers and some bodies. Less durable than brass; clarify whether the part is zinc or brass before quoting. |
| Stainless steel 304 | Corrosion-resistant, lead-free and often used for kitchen faucets, shower hoses and high-end minimalist designs. SUS 304 is the common AISI grade in Chinese production. |
| Electroplated finish | A metallic coating deposited by electrolysis, usually nickel then chrome. Chrome plating is the benchmark for durability and mirror reflectivity. |
| PVD finish | Physical Vapor Deposition bonds the color layer to the surface at high temperature. More scratch-resistant than electroplating; used for brushed gold, gunmetal and black finishes. |
| Salt spray test (NSS / CASS) | An accelerated corrosion test. Entry-level faucets pass 24 h; premium finishes should pass 48–96 h NSS or CASS before mass production. |
| Finish warranty | The manufacturer’s guarantee against peeling, discoloration or corrosion. Ask whether the warranty is 3, 5 or 10 years and what test data supports it. |
| Term | What it means & why it matters to B2B buyers |
|---|---|
| Flow rate (GPM / L/min) | Gallons or litres per minute. US lavatory faucets are typically 1.2–1.5 GPM under WaterSense; kitchen faucets often run 1.5–1.8 GPM. Match the rating to local code. |
| Working pressure | The inlet pressure range the faucet is designed for, commonly 0.05–1.0 MPa (7–145 psi). Low-pressure systems need cartridges that operate below 0.1 MPa. |
| Spout reach / Projection | Horizontal distance from the faucet centre to the water outlet. Too short causes splash on the rim; too long overwhelms a small basin. |
| Thread size (G1/2″ / NPT) | Inlet connection standard. G1/2″ BSP is common in Europe, Asia and the Middle East; 1/2″ NPT is used in North America. Adapters add cost and leak risk. |
| WELS rating | Australia and New Zealand water-efficiency star rating, up to 6 stars. Higher stars mean lower flow and can affect import eligibility and rebate programs. |
| WaterSense label | US EPA program for water-efficient plumbing. Lavatory faucets must be ≤1.5 GPM at 60 psi and ≥0.8 GPM at 20 psi to qualify. |
| Leakage class | European EN standards classify taps by leakage resistance under pressure. Class 1 is the tightest; always request the test class for project work. |
| Rough-in valve | The hidden valve body installed during rough construction. For concealed showers and wall-mounted faucets, the rough-in depth must match the finished wall thickness. |
Compliance and logistics terms determine whether the goods can be installed and who pays for what. The photo below shows final inspection before packing.
| Term | What it means & why it matters to B2B buyers |
|---|---|
| WaterMark certification | Australian and New Zealand mandatory plumbing approval for tapware. Without it, products cannot be legally installed in most AU/NZ states. |
| CE marking | European conformity mark showing the product meets EU safety, health and environmental requirements. CE alone does not replace national water-approval schemes. |
| ACS approval | French sanitary conformity for materials in contact with drinking water. Required for faucet sales in France and often requested in French-speaking markets. |
| NSF/ANSI 61 & 372 | North American standards for drinking-water system components. NSF/ANSI 372 certifies weighted average lead content ≤0.25% on wetted surfaces. |
| UPC / cUPC | Uniform Plumbing Code listing by IAPMO, accepted across most US states and Canadian provinces. cUPC covers Canada; UPC covers the United States. |
| WRAS / KTW approval | UK and German approvals for materials in contact with drinking water. WRAS is recognized across the UK; KTW and DVGW W270 are German requirements. |
| RoHS / REACH | EU chemical safety regulations limiting hazardous substances in products and packaging. Important for customs clearance and large retail buyers. |
| HS code / Incoterms | HS 8481.80 covers taps and cocks. Incoterms such as EXW, FOB or CIF define who pays for freight, insurance and customs handover. |

Basin faucets are shorter, lower-flow fixtures for hand-washing sinks, while kitchen faucets are taller with higher flow and often include a pull-out or pull-down spray. The cartridge, aerator and spout reach are sized for different tasks, so they are not interchangeable on the same sink.
No. WaterMark is the mandatory plumbing approval for Australia and New Zealand, while WaterSense is a voluntary US EPA efficiency label. A faucet can carry both, but each mark serves a different market and requires separate testing.
Lead-free brass limits the lead content on wetted surfaces, typically to a weighted average of 0.25% or lower under NSF/ANSI 372. It is required for drinking-water faucets in the United States, Canada and much of Europe, and it affects both material choice and unit cost.
Request at least two sets: one for approval of appearance, finish and packaging, and one for independent testing or certification review. For multi-market orders, ask for samples in each voltage, thread or flow configuration you plan to sell.
Yes, but specify the finish code clearly on the purchase order and confirm that the supplier can plate all components to the same color standard. Small hardware such as angle valves, flanges and drains should be included in the finish-matching scope to avoid a mismatched installation.
A shared vocabulary is what turns a vague faucet inquiry into a clear, quote-ready specification. Bookmark this glossary for the next time you review a spec sheet, compare supplier offers or brief an inspector. Getting the terms right up front protects margins, avoids compliance delays and keeps projects moving from sample to shipment.
