Wash Basins & Urinals — Complete Guide
Wash basins (lavatories) and urinals are essential sanitaryware fixtures. Wash basins are used in bathrooms, dressing areas, kitchens and washrooms for hand-washing; urinals are used in men's washrooms (commercial, institutional and increasingly residential). Both are made primarily of vitreous china, with modern options in glass, stone, stainless steel and solid surface. The choice depends on mounting style, space, and aesthetic.
Indian sanitaryware is governed by IS 2556 (Vitreous Sanitary Appliances). Major brands: Jaquar, Hindware, Cera, Parryware (Roca), Kohler, Toto, American Standard, Johnson.

Types of Urinals
| Type | Description | Use |
|---|
| Wall-Hung Flat Back | Standard wall urinal | Common commercial |
| Wall-Hung Half Stall | Larger splash guard | Schools, offices |
| Full Stall (Floor) | Floor-to-wall urinal | High-traffic, public |
| Bowl Urinal | Compact bowl type | Small washrooms |
| Waterless / Waterfree Urinal | No flush — sealant trap cartridge | Water-saving, green buildings |
| Sensor Urinal | Auto-flush on sensor | Hygienic public toilets |
| Integrated Flush Urinal | Built-in flush | Modern |
Urinal Flush Systems
- Manual Push Valve: User presses to flush
- Auto Flush Cistern: Periodic timed flush (multiple urinals)
- Sensor / Infrared: Touchless auto-flush on use
- Flush Valve (Flushometer): Direct pressure flush
- Waterless: No flush — odour-sealing cartridge / trap liquid
Waterless urinals save ~1.5 lakh litres of water per urinal per year — ideal for green-rated (IGBC / GRIHA) buildings. They use a sealant liquid or membrane cartridge to block odour without water.

Conclusion
Wash basins and urinals come in a wide range of styles — from economical wall-hung basins to designer counter-top and stone bowls; from standard wall urinals to water-saving waterless and sensor types. Choose ISI-marked vitreous china, mount at correct heights, use bottle traps, and coordinate with the bathroom suite. For commercial washrooms, sensor and waterless urinals deliver hygiene and major water savings.
Basins & urinals connect to drainage PVC pipes, are fed by faucets & taps from tanks / geysers, and pair with matching EWC toilets and kitchen sinks.
