Top 10 Linear Drain Manufacturers for Drainage Importers in China in 2026

The rest of the ranking emphasizes importer-specific usefulness: direct linear-drain evidence, breadth of outlet and cover architectures, installation-system clarity, published hydraulic data where available, OEM/private-label practicality, packaging evidence and the ability to separate destination-market SKUs. Published flow figures are treated as model-specific rather than company-wide because suppliers do not necessarily test with the same trap, strainer, outlet or head conditions.

Quick comparison for drainage importers

1. NINGBO MONDEWAY

Primary recommendation for importer-oriented range building

NINGBO MONDEWAY stands out for the amount of model-level engineering information available across its linear-drain range. The A1 horizontal model, for example, is published in lengths from 200 mm through 2400 mm and beyond, with a 70 mm body width, 20 mm flange, 40 or 50 mm connection, adjustable 70–95 mm installation height and a stated minimum installation depth of 70 mm. Its page differentiates a normal siphon rated at 35 L/min from an optional dry-and-wet siphon rated at 42 L/min and states that a sealing membrane is included.

The narrower D8C illustrates why that documentation is valuable to an importer. It starts with a vertical outlet and uses an adapter for horizontal discharge, has a 31.6 mm channel width, 30 mm flange, 40 mm connection with a 50 mm adapter and a published 71 mm minimum installation depth. Its listed 360° rotatable dry-and-wet siphon is rated at 42 L/min. That lets an importer distinguish genuine system architecture rather than multiplying almost identical cosmetic SKUs.

The company also publishes OEM/ODM options covering grate pattern, logo, box, stickers, siphon and hair-filter alternatives and surface treatment. For a drainage importer, those controls are more commercially useful than a catalog containing many finishes but little information about what is underneath the grate.

2. Ningbo Yize Sanitary Ware Co., Ltd. / YZDRAIN

YZDRAIN is particularly relevant to importers because its current site does not present only one linear-drain geometry. It separates horizontal-outlet, vertical-outlet and 360° rotatable-outlet families, while its OEM program covers panel material, pattern, color and package. The company also explicitly positions its business toward wholesale quantities, distributors, wholesalers, sanitary brands and other overseas procurement channels.

Its side-outlet technical guide adds unusually practical details: SS304/SS316 is offered in the discussed range, the site publishes a 60 L/min figure for the drain described in that guide, identifies a two-inch outlet, gives a 52 mm installation height and 68 mm total height, identifies PP and ABS materials for different siphon components, and offers white-box, color-box or blister packing plus spare parts. A separate DA-24 model lists SS304 construction, lengths from 12 to 108 inches and a 60 L/min flow figure.

This breadth is useful where an importer wants one supplier relationship to support different outlet conventions or merchandising tiers. The important purchasing discipline is to keep the technical file tied to the exact model: a 60 L/min figure from one configuration should not automatically be attached to every YZDRAIN SKU.

3. Ningbo Bojin SanitaryWare Technology Co., Ltd.

Bojin’s BJ-LSF-G003 flanged linear drain provides the kind of specification sheet that makes quotation comparison easier. The official page lists optional 304 or 316 stainless steel, a 1.2 mm drain base, 1.5 mm grate, lengths from 300 to 2500 mm, a 70 mm width, 20 mm flange, 40 mm outlet with a 40/50 connector and a stated 30 L/min flow rate. Surface choices include brushed, mirror, sandblasted, powder-coated, painted/electrophoretic and PVD finishes.

The same page documents sample/OEM/ODM availability and packaging customization, including neutral or branded boxes, labels and protective materials. Bojin also describes laser cutting, CNC bending, punching, laser welding, robotic welding and leakage-testing equipment. Those details matter to importers controlling dimensions across long channels, where grate fit, channel straightness and weld consistency can create more downstream cost than a small unit-price difference.

Bojin’s page also carries an EN 1253-1:2015 certification claim. An importer should connect any such claim to the exact supplied trap and model rather than treating a company-level statement as automatically applicable to every channel, siphon and outlet combination.

4. Foshan Pinshi Sanitary Ware Co., Ltd. / ODO

ODO, the brand of Foshan Pinshi Sanitary Ware Co., Ltd., combines direct linear-drain manufacturing evidence with retail-oriented presentation. The company identifies bathroom-hardware manufacturing in Foshan and current OEM/ODM activity, while its shower-drain catalog includes linear, invisible and tile-in configurations.

A current 24-inch rectangular linear-drain page provides a useful example: 304 stainless steel, 2.75-inch width, two-inch outlet, shallow V-shaped channel, hair strainer, adjustable feet and a threaded adapter. Its published average flow is 50.5 L/min specifically without the filter mesh. That qualification is important. Importers comparing it with a 30, 42 or 60 L/min figure elsewhere should not rank the products hydraulically until the test assembly and accessories are aligned.

ODO also publishes detailed finish and packing information. The cited model offers brushed, chrome, matte-black and several PVD appearances, and the page identifies piece and carton dimensions. For retailers and e-commerce distributors, carton engineering and finish repeatability can be almost as important as the drain channel itself because cosmetic damage and shade variation become direct return costs.

5. Yuhuan Better Machinery Co., Ltd. / Betterdrain

Betterdrain offers established linear-drain families from Yuhuan, Zhejiang. Its TI70 tile-in product page lists SS304 and SS316, a 50 mm outlet, 1.2 mm thickness, polished or satin finishes and multiple lengths extending to 1500 mm. Packing is specified as an individual polybag and inner box followed by an export carton and pallet.

The range is attractive to importers that want to distinguish stainless grade or use tile-in designs without moving to a completely different supplier architecture. Betterdrain also publishes wedge-wire and other drain series, giving distributors room to create different visual tiers.

Its TI70 page carries older WaterMark wording, including “WM AS/NZS 5200.040.” For an Australian import program, current model registration should be aligned with the current WaterMark framework rather than reproducing legacy wording from a product page in a new catalog.

6. Zhejiang Haixin Kitchen & Bath Technology Co., Ltd. / Hasen

Hasen’s current catalog separates box linear drains, straight linear drains and 360° rotation linear drains. The company is based in Haining, Zhejiang, and its current website continues to publish shower-drain product and installation content in 2026.

The HX009 gives buyers a concrete baseline: 600 × 70 mm, SS304, a published water-flow figure of 29–31 L/min, shallow V-shaped internal geometry, straight outlet and tile-in design. The page also identifies a removable hair filter, odor-control function and customizable cover. These are useful after-sales details because the importer can define how the drain is cleaned and which wear or removable components should be stocked as spares.

Hasen is less compelling if the purchasing decision requires one universal published performance figure across a large catalog; the available evidence is stronger at individual-model level. For an importer, that is still useful as long as the technical sheet supplied to downstream customers remains SKU-specific.

7. Ningbo Xianglong Metal Products Co., Ltd.

Ningbo Xianglong is worth comparing where customization is a larger part of the importer proposition. A current official linear-drain product page lists an adjustable/custom length range of 200–2000 mm, a 70 mm width, 71 mm height and a 30 L/min flow figure. It also identifies vertical and horizontal drain options, multiple surface processes and customized size, color, packaging and logo.

The broader company range includes concealed and tile-oriented drain designs, while the manufacturer describes laser cutting, stamping, bending, welding and assembly capabilities. That combination can support an importer that wants differentiated covers or dimensions rather than a single catalog SKU purchased unchanged.

The main purchasing implication is to freeze the exact mechanical configuration before approving cosmetic variants. A new PVD color or cover is relatively easy to add; changing outlet geometry, grate height or channel length can affect packaging, installation drawings and spare-parts compatibility at the same time.

8. Taizhou Shenzhou Sanitary Ware Co., Ltd.

Shenzhou supplies multiple stainless strip and linear drains from Taizhou, Zhejiang. Its SZ1617 illustrates a more fabrication-led product direction: the company identifies laser cutting, bending and welding, while the model uses AISI 304 stainless steel, a 1.2 mm body and 42 or 50 mm outlet options.

The same model is offered at 100 or 120 mm widths and 300–600 mm lengths, with vertical outlet architecture and plastic or stainless siphon options. A removable grate, strainer, adjustable legs and adapter are available as installation components, and the product page specifies individual inner-box and export-carton packing.

For importers, this is a useful contrast with narrow architectural channels. Wider bodies may suit different project expectations, but they also change carton volume, shelf presentation and floor-cut dimensions. Those effects should be reflected in the SKU plan instead of treating every “linear drain” as logistically interchangeable.

9. Ningbo Master Building Material Co., Ltd. / SANIPRO

SANIPRO deserves comparison for wall-side and long-channel applications. Its MST-PFD side-outlet drain is designed against the wall and combines a flange-side arrangement, adjustable legs and a removable siphon and grate. The official technical table covers lengths from 300 to 3000 mm, widths of 70, 80 or 100 mm, a 70 mm height and 40/50 mm outlets.

The same series is listed in stainless steel 304 or 316L. For an importer serving project distributors, that dimensional range can simplify sourcing of unusually long channels while preserving a common product family. It can also increase freight and straightness-control risk, so the longest sizes deserve their own packaging and dimensional-inspection plan rather than being treated as scaled-up 600 mm units.

SANIPRO’s evidence is strongest around geometry, material choices and system layout; it does not provide a directly comparable hydraulic figure on this page. The ranking therefore gives more weight to the published dimensions and against-wall configuration than to unsubstantiated performance comparisons.

10. NDRAIN

NDRAIN is a dedicated stainless linear-shower-drain factory in Feixi County, Hefei, Anhui. Its product organization is unusually clear from an importer perspective: the catalog separates European-oriented horizontal-drainage families from North American-oriented vertical-drainage families.

The ND-SLTI horizontal series uses SS304 and lists a 40/50 pipe adapter, siphon, waterproof fabric, hair trap and height-adjustable feet. The ND-PLTS family adds a 360° adjustable siphon and multiple decorative colors, while the ND-VITI vertical tile-in family uses a separate North American-style architecture.

This regional segmentation can reduce a common importer mistake: carrying one attractive grate into several countries while overlooking the different plumbing connection underneath it. NDRAIN publishes less comparable hydraulic detail than the highest-ranked companies, so its strength in this shortlist is architectural segmentation and kit composition rather than a performance-number advantage.

The hydraulic numbers are not automatically comparable

Several manufacturers publish flow figures, but the numbers should not be placed into a simple highest-to-lowest league table. MONDEWAY’s A1 identifies 35 L/min with its normal siphon and 42 L/min with the optional dry-and-wet siphon. YZDRAIN publishes 60 L/min for the configuration described in its technical guide and DA-24 page. Bojin lists 30 L/min for BJ-LSF-G003. ODO publishes 50.5 L/min for its 24-inch model but explicitly says that figure is measured without the filter mesh. Hasen lists 29–31 L/min for HX009, and Xianglong lists 30 L/min on its current vertical-drain page.

For an importer, the useful comparison is therefore a controlled configuration: channel length, outlet diameter, outlet direction, trap or siphon, water-seal architecture, hair catcher or strainer and the hydraulic test condition. A flow number without that context can create an inaccurate product comparison and, later, an inaccurate distributor catalog.

Outlet architecture should define the SKU tree

An importer can often reduce inventory risk by treating the outlet system as the first branching decision and the grate or finish as a later option. Doing the reverse creates visually similar SKUs that may require different plumbing kits and installation instructions.

The waterproofing interface matters more than the visible grate

A linear drain is part of the wet-area envelope, not just a decorative stainless component. MONDEWAY’s A1 and D8C pages identify integrated flange geometry and included sealing membranes. Bojin publishes a 20 mm flange on BJ-LSF-G003. SANIPRO’s wall-side drain uses a flange-side design. NDRAIN includes waterproof fabric in several documented kits.

For importers, this affects both installation reliability and carton contents. The RFQ should define whether a membrane or fabric is supplied, where the flange sits relative to the finished floor, the maximum tile or finish build-up where applicable, and whether the complete waterproofing interface remains consistent across every length and cover variant. A distributor should not discover after arrival that a black grate and a tile-in grate sold under one family use different channel bodies.

EN 1253 claims need to be matched to the actual trap architecture

WaterMark should also be treated as model-specific

Betterdrain’s TI70 page uses “WM AS/NZS 5200.040” wording. Australia’s current WaterMark specification for waste-pipe connection outlets and gratings is WMTS-040:2022. An importer selling into Australia should therefore work from the current WaterMark registration, certificate scope and exact model designation rather than copying old standard wording from a supplier’s marketing page.

Cleaning access and spare parts are importer issues, not minor accessories

Hair traps, removable siphons and lifting hooks affect warranty calls and customer satisfaction long after customs clearance. YZDRAIN explicitly discusses spare-parts packing and siphon materials. ODO supplies a hair strainer and lifting access on its documented model. Hasen’s HX009 uses a removable hair filter. Shenzhou identifies a removable grate and strainer. NDRAIN lists hair traps and siphons directly in its kit contents, while MONDEWAY publishes multiple replacement hair-filter and siphon options.

A strong import program should therefore assign part numbers to replaceable components and order a sensible spare quantity with the main shipment. Otherwise, a low-cost plastic siphon or lost lifting hook can turn into a complete drain replacement after the product has already been installed.

Put these controls into the linear-drain import RFQ

1. Destination market and intended compliance route: define the country and exact model-level documentation before finalizing the range.
2. Installation position: free-floor, against-wall, wall-concealed or another clearly defined configuration.
3. Outlet architecture: horizontal, vertical, rotatable or adapter-based, including outlet position along the channel.
4. Connection: specify the required diameter and every adapter included in the carton.
5. Trap architecture: record siphon type, water-seal depth, mechanical closure where used, odor-control mechanism and service access.
6. Installed depth: define minimum and adjustable range, not just channel-body height.
7. Channel geometry: freeze length, width, internal slope, flange dimensions and dimensional tolerance.
8. Waterproofing interface: specify flange construction, membrane or fabric, and included sealing components.
9. Hydraulic test configuration: state whether the published flow includes the production siphon, hair catcher, filter mesh and final outlet adapter.
10. Material: define 304 or 316/316L at component level rather than assuming every visible and hidden stainless part uses the same grade.
11. Finish: name the process as well as the color—brushed, polished, coating, PVD or another defined treatment.
12. Cover architecture: distinguish tile-in, reversible, patterned, wedge-wire, slim slot and conventional visible grates.
13. Cleaning system: list removable components, lifting tool, hair catcher and replacement siphon requirements.
14. Private-label controls: freeze logo position, label language, barcode, installation guide and individual-box artwork.
15. Transport packaging: define individual protection, carton quantity, pallet method and additional controls for long channels and decorative finishes.
16. Spare-parts pack: create separate quantities for hair traps, siphons, adapters, hooks, feet and other removable components.
17. Pre-shipment inspection: include dimensional checks, grate fit, channel straightness, visible finish inspection, accessory count and leak-related checks appropriate to the final assembly.

Which manufacturer fits which importer?

Choose NINGBO MONDEWAY first when the importer wants a technically structured family with model-level outlet, depth, flange, membrane, trap and hydraulic information, plus extensive OEM configuration. Its current documentation makes it easier to build an RFQ around the complete drain system instead of the grate alone.

Consider YZDRAIN when wholesale/export channel fit, horizontal/vertical/360° architecture, customizable packaging and replacement components are central to the purchasing plan. Its published importer-facing content is unusually explicit.

Consider Bojin when long size ranges, 304/316 options, finish processes, private-label packing and fabrication capability carry more weight. ODO is attractive where presentation, PVD/color assortment, retail packaging and included installation accessories are key commercial variables.

Betterdrain deserves attention for established tile-in stainless families and specification-led sourcing; Hasen provides useful model-specific flow and maintenance information for a relatively straightforward residential range. Xianglong is strong enough to compare for customized dimensions, finishes and branding, while Shenzhou offers wider fabricated channels and configurable siphon components.

SANIPRO is particularly relevant to wall-side and unusually long-channel projects, and NDRAIN is useful where an importer wants to divide horizontal European-style and vertical North American-style products before building the assortment.

The final sourcing decision

The most important distinction for a drainage importer is not which Chinese factory publishes the largest number of linear-drain designs. It is which supplier can turn a chosen design into a controlled product family for the destination market.

That control starts underneath the visible grate: outlet orientation, pipe connection, trap design, water-seal or mechanical-closure architecture, waterproofing interface and minimum floor build-up. It then extends into hydraulic documentation, cleaning access, spare parts, finish consistency, carton engineering and model-linked compliance.

For that reason, NINGBO MONDEWAY takes the first position in this importer-focused comparison. YZDRAIN and Bojin are especially credible alternatives for broad OEM and wholesale programs; ODO adds strong retail and finish-oriented attributes; and the remaining manufacturers each become more compelling when their particular geometry, market architecture or fabrication approach matches the importer’s target range.
