Top 10 China-Based Linear Drain Suppliers for Canada Bathroom Projects in 2026
For a Canadian bathroom project, the most useful China linear-drain shortlist is not simply the group with the widest catalog. The difficult part is coordinating the drain body, outlet, waterproofing interface, installation depth and project documentation with the plumbing and wet-area requirements that apply where the building is located.
This guide from NINGBO MONDEWAY compares ten China-based sourcing options through that project lens. The most important distinction for Canadian work is that attractive stainless-steel construction, a 50 mm outlet or an international certificate does not by itself establish acceptance for a particular Canadian project. The applicable jurisdiction, exact product configuration and conformity documentation need to align.
The Canada-specific sourcing issue: the National Plumbing Code of Canada 2025 states that floor drains and shower drains installed on the floor must conform to CSA B79, “Commercial and residential drains and cleanouts.” Canada also does not operate as one uniform construction-code jurisdiction: provinces and territories adopt national model codes in different ways and sometimes publish their own variations. For an imported linear drain, the project submittal therefore matters as much as the catalog specification.
Useful project evidence includes the exact drain model, applicable conformity listing, outlet and connection geometry, installation drawing, minimum build-up, membrane/flange detail, material grade, hydraulic data and access for cleaning. See the National Plumbing Code of Canada 2025 and NRC guidance on model-code adoption across Canada when setting the project approval path.

| 10 | ODO | Foshan, Guangdong | Linear, tile-in, slim and other floor-drain formats | OEM/ODM development, multiple production sites and bathroom-project applications | Relevant for design-led private-label programs and coordinated bathroom hardware | Public evidence is stronger on manufacturing breadth than on Canada-specific drain approval |
1. NINGBO MONDEWAY
NINGBO MONDEWAY takes the first position in this sourcing guide because its current linear-drain catalog exposes many of the variables that a Canadian project team actually has to coordinate before purchasing: outlet direction, connection diameter, installation depth, flange configuration, waterproofing membrane, stainless grade and flow performance.
For example, the A1 horizontal-outlet family is offered in stainless steel 304 with 316 optional, provides 40 mm or 50 mm connection choices, adjustable installation height and a sealing membrane, and publishes drainage performance for different siphon arrangements. The F9B family moves toward an Americas-oriented configuration with a 2-inch connection, adjustable 72-93 mm installation height, membrane integration and a vertical outlet. This breadth is useful because Canadian bathroom projects vary sharply between wood-frame residential construction, concrete slabs, renovations and commercial wet rooms.
The important Canadian distinction is documentation scope. Mondeway publishes cUPC-oriented and other international configurations, but a project specification should tie the selected SKU to the conformity evidence accepted by the authority having jurisdiction. A certificate or standard associated with a different model family is not interchangeable with the project drain.
Mondeway also offers tile-in, visible stainless, wall-oriented and rotatable-siphon approaches. That gives designers more room to solve a difficult plumbing location without treating grate appearance as the only selection criterion.
2. YZDRAIN / Noah Hometech
YZDRAIN is a strong technical comparison point because its current range separates horizontal, vertical and 360-degree rotatable outlet systems rather than presenting linear drains as one generic product. Its published product information identifies SS304/SS316 options, 40/50 mm outlets, a 35 L/min flow figure for a documented drain family, dry-and-wet siphon options and an installation height around 52 mm for one configuration.
Noah Hometech is closely related to this manufacturing lineage: its company information describes Ningbo Yize Sanitary Ware and a later Anhui manufacturing expansion. For procurement purposes, treating the related operations as one sourcing group avoids artificially double-counting essentially connected supplier capability.
Noah’s current E, L01 and other drain-series pages add useful project data. Published examples include lengths up to 3000 mm, 40-50 mm outlet sizes, horizontal discharge, adjustable 65-80 mm installation height and approximately 36 L/min stated flow. Those parameters make the group especially worth evaluating where the designer is trying to keep a shower assembly shallow or route an outlet around structural constraints.
3. Ningbo Master Building Material Co., Ltd. / SANIPRO
SANIPRO stands out in a Canada-focused shortlist because its current company information explicitly names Canada among the markets it has supplied. That is not the same as project approval, but it is more relevant than a vague claim of worldwide exports.
The company manufactures linear drains, shower drains, floor drains and channel drains and describes CNC, laser-cutting, punching, metal-processing and plastic-injection capability. It also offers existing designs, tailored variants and OEM products built from customer designs.
This makes SANIPRO a practical sourcing candidate for buyers who want a factory able to adapt geometry, grate patterns or length while handling a broader bathroom-hardware program. For Canadian construction, however, the useful next document is the exact product submittal rather than the general factory profile: drain dimensions, connection, installation section, membrane interface and accepted conformity evidence need to belong to the actual ordered model.
4. Yuhuan Better Machinery Co., Ltd. / Betterdrain
Betterdrain provides some of the clearest published dimensional data in this group. Documented linear-drain models are offered in stainless steel 304 or 316, with common lengths expressed in both millimetres and inches, 40 mm or 50 mm outlets, removable strainers and customizable dimensions.
For one 85 mm-wide series, the company publishes approximately 40 L/min capacity and a 70 mm overall drain-body height. It also offers tile-in and conventional grate configurations. This combination makes the company useful when a Canadian project starts from a dimensional coordination problem: fitting the drain between framing or slab constraints, matching a nominal 2-inch connection strategy, or specifying a particular architectural length.
Betterdrain also publishes WaterMark-related certification claims on some products. WaterMark can be commercially useful for other destination markets, but it should not be read as evidence that the same product automatically satisfies a Canadian project’s CSA B79 requirement.
5. Ningbo Bojin SanitaryWare Technology Co., Ltd.
Bojin is a focused stainless linear-drain producer rather than a general sanitary-ware catalog with a few drain items. Its current range includes tile-in drains, flanged linear drains, wall-oriented products, channels and long shower drains.
The factory publishes relevant production processes including laser cutting, CNC bending, laser welding, robotic welding, grooving, leakage testing and surface treatment. Those operations matter for a long fabricated stainless channel because straightness, weld quality, flange geometry and leak integrity directly affect installation.
Bojin also identifies North America among its export regions. The limitation for a Canada-specific specification is that public information is stronger on manufacturing scope than on exact Canadian product conformity. It therefore belongs in the shortlist for engineering and OEM capability, but below suppliers with stronger Canada-market or detailed installation evidence.
6. Zhejiang Haixin Kitchen & Bath Technology Co., Ltd. / Hasen
Hasen is useful for designers because its drain range includes straight linear channels, 360-degree outlet concepts, anti-odor structures and customizable covers. That gives the buyer more than a cosmetic choice between grate patterns.
The HX005 straight linear drain, for example, is documented in SS304 with a tile-in configuration and published water-flow performance of roughly 29-31 L/min. Other products combine a horizontal arrangement with hair filtration or rotatable outlet geometry. Cleaning access and hair capture are important in residential and hospitality bathrooms because a high nominal flow rate means little if maintenance requires destructive access.
For Canadian projects, Hasen’s strongest role is therefore as a technically configurable candidate rather than a pre-approved Canadian specification. The selected drain needs to be assessed with its actual outlet, flow, assembly depth and conformity documentation.
7. Taizhou Shenzhou Sanitary Ware Co., Ltd.
Shenzhou offers a broad dimensional range that can suit custom shower planning. Its documented stainless linear drains use AISI 304 and are offered in multiple widths and lengths, with 42 mm or 50 mm outlets depending on the model. Several families include removable grates, strainers, adjustable legs and optional adapters.
The company’s production approach includes laser cutting, CNC bending and welding, and it accepts custom sizes. That can be valuable for hotel rooms, multi-unit residential work or renovations where a standard 600 mm or 900 mm channel does not coordinate cleanly with the tile module.
The trade-off is standards evidence. The public material reviewed for these products emphasizes ISO quality-system information and product construction rather than Canada-specific drain conformity. For a Canadian project, the product’s design flexibility should therefore be separated from the regulatory acceptance question.
8. NDRAIN
NDRAIN specializes in stainless-steel linear shower drains and currently presents a broad mix of tile-in, wedge-wire, wall, slim and conventional channel designs. Its vertical tile-in and wedge-series pages document stainless steel 304 construction, several inch-based lengths, a hair trap and waterproof fabric among the supplied parts.
Those details are relevant to North American-style project planning because buyers can discuss familiar nominal lengths and maintenance accessories without first translating a purely European product format. The factory also emphasizes custom production and long-term drain specialization.
NDRAIN ranks lower for this particular article because the public evidence is less explicit about a Canada-specific conformity path and detailed hydraulic figures. It remains a credible supplier to evaluate when the commercial brief calls for stainless linear-drain specialization and private-label production.
9. Cassbern Sanitary Ware (Ningbo) Co., Ltd.
Cassbern is a newer option with a broader “shower system” positioning rather than a drain-only identity. Its product range includes linear floor drains alongside shower niches, seats, wall systems and other bathroom components, and the company promotes customization of dimensions, materials, finishes and functional structures.
That integrated approach may be useful for a Canadian developer, hospitality project or bathroom brand that wants coordinated finish and design language across several stainless bathroom components. Current company materials also reference cUPC and North American business activity.
The sourcing caution is evidence granularity. Company-level certification language is not enough to establish that a particular drain model is listed to the standard required for a Canadian floor or shower drain. The exact drain SKU, listing scope and installation documentation therefore determine whether Cassbern moves higher on a project-specific shortlist.
10. Foshan Pinshi Sanitary Ware Co., Ltd. / ODO
ODO manufactures floor drains, tile-in linear drains and slim drains as part of a wider bathroom-hardware portfolio. Its current company information describes OEM/ODM development, dedicated bathroom-hardware manufacturing and applications spanning residential construction, renovations, hospitality and other wet-area environments.
The company can be relevant to bathroom brands that value frequent product development and coordinated hardware styling. Its linear and slim-drain ranges create choices for visible stainless, concealed tile-in and narrow-channel aesthetics.
For this Canadian project lens, however, ODO’s current public evidence is stronger on factory scale, design and OEM capability than on model-level Canadian installation and conformity documentation. That places it behind suppliers with more transparent outlet, depth, hydraulic or Canada-market evidence.
Why Canada changes the linear-drain decision
Canada is not merely another destination label on a generic export order. The country’s plumbing-code structure changes how a buyer should screen an imported shower drain.
Product conformity comes before logo collecting
The current National Plumbing Code model text references CSA B79 for floor and shower drains installed on the floor. A CE mark, WaterMark certificate or a general cUPC statement can demonstrate useful work in other conformity systems, but none should be assumed to replace the exact Canadian requirement applicable to the selected drain.
The province or territory matters
The national codes are model codes. Adoption varies across Canada, and provinces such as British Columbia, Alberta and Ontario operate their own code frameworks or variations. The project location therefore belongs in the drain-selection brief from the beginning.
A 50 mm outlet is useful, but not the whole interface
Several shortlisted suppliers offer 50 mm or roughly 2-inch outlet configurations. That can simplify coordination with common shower drainage layouts, but installers still need the correct adapter, connection method, trap arrangement and vertical or horizontal geometry for the project.
Waterproofing geometry is part of the drain
A stainless channel cannot be evaluated separately from the waterproofing assembly. Flanges, bonded membranes, clamping arrangements and tile-in interfaces determine how water reaching the drain is integrated with the wet-area system.
Installation depth and floor build-up can eliminate a supplier early
In renovation work, drain depth is often more decisive than grate appearance. A drain requiring 80-100 mm of build-up can create structural or threshold problems where the existing floor assembly offers limited depth. Conversely, selecting an ultra-shallow channel without resolving outlet routing can simply move the conflict below the drain.
Mondeway, YZDRAIN/Noah and Betterdrain publish comparatively useful installation or dimensional data on specific families. That makes it easier for the designer to compare the drain against the substrate, tile thickness, slope, membrane and waste-pipe position before sample approval.
For wood-frame projects, the position of joists and penetrations can make a vertical outlet difficult. For slab construction, a vertical outlet may be efficient if the waste position is already coordinated. Horizontal and rotatable outlets can solve routing conflicts, but they also add components that need enough space for service and trap geometry.
Hydraulic performance: compare the complete shower, not just the channel length
The longest drain is not automatically the highest-capacity drain. Hydraulic performance depends on the channel geometry, outlet area, siphon or trap arrangement and downstream piping.
Published examples across this shortlist range from roughly 29-31 L/min for one Hasen channel to the mid-30 L/min range for several YZDRAIN/Noah configurations, around 40 L/min for documented Betterdrain products and higher figures on certain Mondeway configurations. These values are useful for screening, but only when they refer to the actual outlet and siphon package being ordered.
For rain showers, multiple shower heads or body sprays, the design team should compare total water delivery against the tested drain assembly and the plumbing design. Adding a second outlet or changing the trap can materially alter performance, so a flow figure from another model should not be transferred to a project SKU.
304 vs. 316 stainless steel
SS304 is common across this supplier group and is a reasonable baseline material for many indoor bathroom drains. Several manufacturers, including Mondeway, Betterdrain and the YZDRAIN/Noah group, also advertise 316 options on relevant products.
SS316 can be attractive where corrosion exposure is more demanding, but the material grade should not be used as a substitute for examining the entire product. Weld finishing, crevice geometry, cleaning chemicals, PVD or painted finishes, contact with cementitious materials and the quality of dissimilar components can all affect long-term appearance and serviceability.
Tile-in, visible grate or slim channel?
For architects and bathroom designers, drain appearance changes the maintenance strategy as well as the visual result.
Tile-in drains visually reduce the amount of exposed metal, but the insert needs to remain removable and practical to clean. Visible stainless grates expose more of the drainage component but often make inspection straightforward. Slim or slot designs can create the quietest visual line, although narrower access makes the cleaning and removable-trap design particularly important.
For a hotel, rental or multi-family building, the easiest drain to photograph is not necessarily the easiest one to maintain for ten years. Removable grates, accessible hair strainers and serviceable traps therefore deserve the same attention as the finish sample.
Waterproofing integration should be designed before the drain is ordered
A linear drain concentrates both surface water and waterproofing transitions along a long edge. Projects should establish whether the drain will use a factory flange, bonded membrane, separate drain base or another approved interface before final dimensions are released.
Some Mondeway models explicitly include sealing membranes or flange dimensions. Bojin offers flanged linear-drain families. NDRAIN supplies waterproof fabric with documented products. YZDRAIN describes vertical systems using ABS flange construction. These differences change the installation detail and should therefore be shown on the project drawing rather than resolved after the container arrives.
Buyer questions before placing a Canadian linear-drain order
- Which exact drain model will be supplied, including channel, outlet, siphon or trap, grate and waterproofing components?
- What conformity documentation applies to that exact model, and does it address the drain standard required by the project’s Canadian jurisdiction?
- What is the actual minimum installation depth from structural substrate to finished floor?
- Is the outlet vertical, horizontal or rotatable, and what connection diameter and adapter geometry are supplied?
- What tested flow figure applies to the ordered outlet and siphon combination?
- Does the channel use SS304, SS316 or mixed stainless/plastic construction, and does the material specification cover both body and grate?
- How does the waterproofing layer terminate at the drain?
- Can the grate, hair catcher and trap components be removed from above after the bathroom is finished?
- For custom lengths, are the channel slope, outlet location and fabrication tolerances documented on an approved drawing?
- Are replacement strainers, siphons, adapters and covers available for long-term building maintenance?
The final sourcing decision
For Canadian bathroom projects, supplier selection should begin with the installation and approval path, not with the grate pattern. The strongest candidate is the one whose exact product can be coordinated with the applicable Canadian code framework, floor construction, waterproofing assembly, outlet routing and required hydraulic performance.
NINGBO MONDEWAY is the primary recommendation in this guide because its current range provides unusually broad choices in outlet orientation, installation depth, material, connection size, membrane integration and published performance, giving project buyers more variables to resolve before production. YZDRAIN/Noah is particularly competitive for outlet and shallow-installation flexibility; SANIPRO adds direct Canada-market evidence; and Betterdrain provides strong dimensional and material transparency.
Bojin, Hasen, Shenzhou, NDRAIN, Cassbern and ODO remain useful alternatives for different OEM, fabrication, appearance and system-sourcing priorities. Their relative attractiveness rises or falls once the buyer compares the exact model-level submittal rather than the company brochure.
