1. NINGBO MONDEWAY

Best fit: buyers wanting a broad concealed-drain platform rather than one isolated tile-in model.

NINGBO MONDEWAY’s current range gives buyers several ways to achieve a concealed finish. Its dedicated Invisible series uses a tile-insert chassis, while the broader shower-drain portfolio includes linear, wall, slim and horizontal/vertical outlet families. That matters when one development needs a common visual language across standard bathrooms, shallow renovations and wall-edge installations.

The A1 linear system is particularly useful as a specification reference. Mondeway lists a maximum drainage capacity of 42 L/min, a minimum installation depth of 70 mm and a maximum tile thickness of 12 mm, together with a removable siphon, anti-clogging components and a flange/waterproofing approach. Its D5L family adds a 360-degree rotatable siphon and lists 48 L/min with an 80 mm minimum installation depth. Buyers can therefore select outlet and installation architecture before choosing the decorative top treatment rather than forcing one drain body into every bathroom layout.

Why it ranks first here: the product architecture covers the entire problem behind concealed drainage—tile integration, siphon serviceability, waterproofing interface, outlet routing and renovation depth—while the dedicated invisible range makes concealment a product family rather than an incidental grate option.

RFQ priority: identify the exact invisible or tile-capable model, tile/stone thickness, outlet direction, trap architecture and required tested flow before the quotation is locked.

2. Ningbo Bojin SanitaryWare Technology Co., Ltd.

Best fit: importers who want unusually granular public specifications for a conventional tile-insert linear drain.

Bojin documents its BJ-LSF-TPG01 tile-insert shower linear drain with 304 or optional 316 stainless steel, a 40 mm outlet, 20 mm flange, adjustable supports and an integrated siphon. Its tile tray accepts floor finishes up to 14 mm according to the current product page, while the cover, hair filter and siphon components are designed to remain accessible for maintenance.

The same product family publishes a 30 L/min flow figure, while another tile-insert channel configuration lists 35 L/min and broader 40/45/50/50.8 mm outlet choices. That model-level detail makes Bojin easier to screen during preliminary engineering than suppliers whose catalog shows attractive invisible drains without corresponding connection or flow information.

Trade-off: do not treat the different Bojin flow figures as interchangeable. They belong to different drain configurations, so the quotation and hydraulic submittal should identify the exact body, outlet, siphon and filter arrangement.

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

Best fit: projects where pipe direction and waterproofing layout must be decided before the finish.

SANIPRO stands out for the breadth of its tile-insert architecture. Its current catalog includes tile-in versions with side outlets or vertical outlets and with or without flanges. The FST side-outlet tile-in family lists 40/50 mm outlets, 70/80/100 mm widths, adjustable supports, a removable siphon and 304/316L stainless material options; the FVT family provides the same tile-or-glass insert concept around a vertical outlet.

This is valuable for concealed-finish work because the drain’s appearance can remain consistent while the plumbing geometry changes. SANIPRO’s own company information identifies Ningbo Master Building Material Co., Ltd. as the manufacturer/exporter behind the brand and describes linear-drain production supported by CNC, laser-cutting, punching and other metal-processing equipment.

Trade-off: its dimension and outlet documentation is stronger than the hydraulic information on the cited tile-in product pages. For projects with high-output shower systems, add a model-specific flow requirement to the submittal package rather than estimating from outlet diameter alone.

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

Best fit: importers building a product line that includes both invisible tile-in and exposed-grate drains.

YZDRAIN’s current linear-drain category includes several tile-in products, including adjustable tile-insert shower slot drains with flanges and other concealed-finish variants. The factory is Ningbo Yize Sanitary Ware Co., Ltd., based in Ningbo, Zhejiang, and its official company information identifies shower-drain manufacturing as a core activity.

A 2026 manufacturer guide from YZDRAIN gives this supplier additional relevance to the current buying decision: it distinguishes recessed tile-in trays from visible grate covers and discusses 304/316 stainless construction, removable tile trays, optional trap configurations and side or bottom outlet choices. That makes YZDRAIN particularly useful for buyers trying to merchandise two visual approaches from a common supplier base.

Trade-off: the current tile-in category is stronger on available architectures than on a single standardized hydraulic figure. The exact drain selected for a project should therefore carry its own flow, trap and connection specification.

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

Best fit: buyers using published hydraulic capacity as an early screening criterion.

ODO’s current shower-drain range includes tile-insert and invisible linear products, backed by Foshan Pinshi Sanitary Ware Co., Ltd. and bathroom-hardware manufacturing in Guangdong. Its documented 24-inch tile-in linear drain uses 304 stainless steel, a 2-inch outlet, an internal U/V-shaped channel, adjustable feet and a removable hair strainer.

The unusual differentiator is the published drainage figure: ODO states an average 50.5 L/min for the cited configuration without the filter mesh. That caveat matters. A buyer comparing the figure with a competitor’s drain tested with its siphon, hair filter or a different hydraulic head would not be comparing equivalent assemblies.

Trade-off: ODO’s published number is useful for screening, but the final project calculation should use the assembled configuration that will actually be installed.

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

Best fit: concealed wall-edge drainage and layouts where the waste pipe does not align neatly with the drain center.

Hasen provides two particularly relevant architectures. The HX011 wall-mounted linear drain combines an SS304 body, a reversible 2-in-1 tile-insert cover, siphon and concealed wall-edge installation; the official specification lists 28–30 L/min. Its HX007 uses a 360-degree rotatable outlet, tile-insert design, SS304 body and a published 29–35 L/min range.

The company behind the range, Zhejiang Haixin Kitchen & Bath Technology Co., Ltd., identifies itself as a Zhejiang manufacturer of shower drains and related stainless-steel kitchen and bathroom products.

Trade-off: wall drains shift critical installation work toward the wall/floor junction. They can deliver an exceptionally clean floor plane, but the waterproofing and recess detail should be designed as a system rather than improvised after tiling begins.

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

Best fit: straightforward stainless tile-in programs with several standard lengths and material choices.

Betterdrain’s TI70 range is explicitly described as a tile-insert linear shower drain and is offered in lengths from 600 to 1500 mm with a 50 mm outlet, SS304 or SS316 material and a 1.2 mm body thickness. The company’s hidden TI85 configuration adds a side-outlet approach for installations where a vertical connection is inconvenient.

Yuhuan Better Machinery Co., Ltd. identifies its head office and factory in Yuhuan, Zhejiang and describes integrated product design, development and production.

Trade-off: the published tile-in pages are clear on outlet, dimensions and stainless grades but less useful for direct hydraulic comparison. Specify a tested flow for the ordered length, outlet and trap combination when shower output is demanding.

8. Ningbo Xianglong Metal Products Co., Ltd.

Best fit: customized OEM programs where the concealed finish must be coordinated with outlet position, channel depth and private-label requirements.

Ningbo Xianglong Metal Products Co., Ltd. is a Ningbo-based stainless-steel floor-drain manufacturer with in-house metal-fabrication capabilities. Its 2026 technical material specifically addresses tile-insert and invisible drains, including removable tile trays, waterproofing interfaces, cleaning access and project-specific cover geometry.

The company’s current OEM guidance also discusses tile-insert covers alongside vertical, horizontal and 360-degree outlet choices, 40/50/75 mm connection options and multiple drain-body depths. That configuration flexibility is more important to an OEM buyer than the number of decorative grate patterns because it affects how one product platform can be adapted across regional plumbing systems.

Trade-off: project-specific technical statements should remain tied to the exact production drawing and test submittal rather than being generalized across every drain in a broad OEM portfolio.

9. Taizhou Shenzhou Sanitary Ware Co., Ltd.

Best fit: custom stainless tile/marble channels where manufacturing flexibility is more important than a highly standardized catalog architecture.

Shenzhou’s official range contains a dedicated tile-insert linear stainless-steel shower-drain family for tile and marble. Listed configurations include 80, 100 and 120 mm widths, custom-size models and an AISI304 version described for higher drainage volume.

The Taizhou manufacturer describes its production capabilities as including laser cutting, CNC bending and robot laser welding, while its factory address places the company in Luqiao District, Taizhou, Zhejiang.

Trade-off: the range supports custom geometry, but buyers designing around a defined shower output should attach their required hydraulic performance and outlet drawing to the RFQ instead of assuming that a longer or wider channel automatically drains faster.

10. Kaiping City Jinqiang Hardware Products Co., Ltd. / Kimpower

Best fit: cost-conscious programs prepared to qualify the exact drain configuration through project documentation.

Kimpower, operated by Kaiping City Jinqiang Hardware Products Co., Ltd., offers tile-insert stainless linear floor drains as part of a broader floor-drain manufacturing program. One current product is offered in 300, 600, 800 and 1000 mm lengths, while another anti-odor tile-in linear family extends through multiple lengths to 1100 mm.

The manufacturer identifies its factory in Kaiping, Guangdong and describes itself as a producer of stainless-steel sanitary floor drains.

Trade-off: Kimpower’s current product information establishes tile-in linear-drain relevance, but its public specifications provide less hydraulic and waterproofing detail than the manufacturers placed higher in this guide. It is therefore better suited to procurement processes that include detailed engineering submittals before order approval.
