Wholesale Floor Drains
Drain configurations planned around outlet position, tiled floor build-up, waterproofing, required fall and approved drawings.
Floor Drains collect surface water at a planned low point and connect that drainage point with the selected floor build-up. WNS Global supports importers, distributors, developers, hospitality procurement teams, contractors, showroom buyers and project specifiers with sourcing around drain type, body and grate dimensions, outlet orientation and connection size, waterproofing interface, required fall, tile insert or finish, cleaning access and project documents. Final values remain subject to approved specification. WNS Global is the sanitary ware supplier for this category rather than its maker: the products come from vetted sanitary ware manufacturers in Foshan, and specification, inspection and export are handled here as one contact.

Product definition
What Are Floor Drains?
Floor Drains are drainage fittings that collect surface water at a planned low point and connect it to a site drainage route. A selected drain must coordinate with body and grate dimensions, outlet orientation and connection size, floor build-up, waterproofing interface, required fall, finished tile thickness, tile insert or finish and access for cleaning. The visible grate is only one part of the decision: the buyer should align the full configuration with the project drawing and the responsible drainage and waterproofing trades.
A styled image does not define complete supply. Do not assume the supply includes drainage pipework, waterproofing, tile, installation, floor preparation or other visible accessories unless the approved quotation names that scope.
Not the same as
- A complete drainage and waterproofing system
- A confirmation that pipework, tile or installation is included
- A substitute for approved floor slope and drainage drawings
Decision guide
Floor Drain Comparison
Compare the drain route with floor integration, planning variables, project fit and drawing verification.
| Approach | Installation or integration | Typical project fit | Buyer confirmation point |
|---|---|---|---|
| Square floor drain | Point-drain body coordinated with a local low point and outlet route. | Hotel bathrooms, utility areas and compact shower floors. | Grate size, floor fall, outlet position and waterproofing interface. |
| Linear floor drain | Long-format channel coordinated with shower layout, tile direction and floor fall. | Walk-in showers, wet rooms and tiled shower areas. | Channel length, outlet route, floor build-up and cleaning access. |
| Invisible or tile-insert floor drain | A tile-insert appearance coordinated with finish depth, slope and service access. | Premium wet areas and finish-led project bathrooms. | Tile insert, waterproofing detail, outlet direction and approved finish reference. |
