Top 2 China-Based A Series Horizontal Outlet Linear Drain Suppliers for Netherlands Bathroom Projects (2026)

The requested Top 10 has therefore been reduced to two. China has many factories producing side-outlet or linear shower drains, but similar appearance is not enough for this sourcing task. Series names are manufacturer-specific, and a generic stainless-steel side-outlet channel should not be treated as an interchangeable A-Series system without corresponding product-family documentation.

What Changes the Decision for a Netherlands Bathroom Project?

The Netherlands adds a meaningful specification layer because a drain must be evaluated as part of the complete indoor wastewater and wet-floor assembly rather than only as a stainless-steel channel. The Dutch standards organization NEN currently lists NEN-EN 1253-1 for trapped floor gullies with a water-seal depth of at least 50 mm. NEN also lists NEN-EN 1253-6 for floor gullies with a water seal below 50 mm, but that part has specific limitations on the building and drainage arrangement.

This distinction is important for shallow renovation floors. A low overall product height does not by itself establish that a drain is suitable for every Dutch project. The project team needs the water-seal configuration, outlet centerline, pipe gradient and total build-up to work together. NEN-EN 12056-2 is the current Dutch adoption covering layout and calculation principles for gravity sanitary pipework inside buildings.

Waterproofing also changes supplier suitability. For tiled wet areas using liquid-applied waterproofing beneath ceramic finishes, NEN lists NEN-EN 14891. In practical procurement terms, this makes the drain flange, membrane transition and tile build-up as important as the visible grate.

Quick Comparison for Netherlands Bathroom Sourcing

1. NINGBO MONDEWAY

NINGBO MONDEWAY documents a dedicated “A Series Hori outlet” product family rather than describing horizontal discharge as an occasional option on a generic channel. Its current drain portfolio identifies A1, A2, A3, A5, A9B, A1F30, A5X, A11, A1X, A3X, A9 and A12 within the horizontal-outlet family.

That product-family structure is useful for Dutch project work because the first decision can be the plumbing architecture—horizontal discharge—while the project team subsequently selects the channel, cover, tile interface and trap arrangement that fit the bathroom section.

Installation depth and outlet coordination

Mondeway’s A1 documentation describes horizontal installation, adjustable height and a minimum installation depth of 70 mm. The same model publishes a maximum drainage capacity of 42 L/min. Its A3 documentation gives an 80 mm minimum installation depth and a maximum drainage capacity of 45 L/min.

Those differences show why an A-Series purchase should be model-specific. For a Dutch renovation with limited floor build-up, choosing simply by family name is insufficient. The contractor needs the exact model section, outlet centerline and trap dimensions before fixing screed depth and pipe routing.

Waterproofing and tile interface

The A1 uses an extended flange concept intended to simplify tiled installation, and the current product information gives a maximum tile-thickness figure of approximately 12 mm for that model. Other A-family products use tile-in, wide-flange or concealed-cover approaches.

This is commercially useful for Netherlands projects because the drain-to-waterproofing transition can be selected as part of the product architecture rather than improvised after the channel arrives. The project detail should still identify the exact waterproofing material, bonding zone, adhesive build-up and finished tile thickness.

Cleaning and serviceability

A1 product information describes a removable siphon and alternative filter arrangements. Serviceability matters particularly with tile-in or concealed finishes: the decorative result is only practical when the trap and debris-catching components remain accessible after completion.

Material choice

Mondeway’s current A-Series product material documents SUS304 extensively, while individual horizontal-outlet product information also presents SS304/SS316 options. A Dutch indoor residential shower does not automatically require 316 stainless steel; material grade should follow the actual chemical and environmental exposure rather than being used as a substitute for drainage or waterproofing performance.

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

YZDRAIN is operated by Ningbo Yize Sanitary Ware Co., Ltd., a Ningbo-based sanitary-ware manufacturer. Its current product selector separates linear drains by outlet architecture and places the A-Series within its horizontal-outlet offering.

The A-Series page describes the family as a horizontal-outlet long shower drain with an anti-odor core. More importantly for specification work, individual A-family product pages provide usable dimensions rather than relying only on lifestyle descriptions.

Published dimensional envelope

Selected A-Series models A-02S and A-07 list lengths from 300 to 3000 mm, a width of 70 mm and an overall height of 69 mm. That range gives designers substantial freedom to align channel length with shower dimensions.

For Netherlands projects, the 69 mm product height is only the starting point. The complete construction must also accommodate the outlet connection and pipe fall, and the trap configuration needs to be evaluated against the applicable project drainage specification.

Hydraulic data

YZDRAIN publishes a 35 L/min flow rate for both A-02S and A-07. This is useful because it provides a model-level performance figure that can be compared with the shower design flow rather than assuming that every long channel automatically has high capacity.

The project schedule should keep the selected model, trap, outlet and hydraulic value together. Changing a siphon or outlet configuration during procurement can alter the installed system even when the stainless-steel channel looks unchanged.

Material and finish

The cited A-Series models use SS304 and are offered in multiple finishes. Product pages also distinguish base, pattern-panel and tile-panel thicknesses, which can help a project team understand that the visible cover and supporting channel are separate construction elements.

Where YZDRAIN fits best

YZDRAIN is a strong comparison supplier for developers or importers wanting a second China-based A-Series platform with straightforward dimensional and flow information. Its public A-Series documentation is especially useful at the early comparison stage, when channel length, width, installed height and nominal hydraulic capacity need to be screened quickly.

Why Other Chinese Side-Outlet Drain Factories Are Not in This Ranking

Broader research identifies additional China-based manufacturers of stainless-steel side-outlet linear drains. Some publish credible specifications, custom lengths, flange designs or 304/316 material options. Those capabilities are relevant to the wider linear-drain market, but they do not establish the same product identity required here.

“A Series” is not an industry standard. It is a supplier-specific naming convention. Including every factory that produces a visually similar horizontal drain would blur the distinction between a direct product-family comparison and a generic side-outlet supplier list. For this article, supplier count is therefore lower but product equivalence is clearer.

Failure-Risk Checks That Matter in Dutch Bathrooms

1. Do not compare overall drain height without the trap section

A 69 or 70 mm channel dimension can appear ideal for renovation work, but the complete system also needs room for the trap, outlet socket and horizontal pipe fall. The floor section should show all of them together.

2. Match water-seal design to the applicable project standard

NEN-EN 1253-1 addresses trapped floor gullies with a water seal of at least 50 mm. NEN-EN 1253-6 addresses shallower seals under defined conditions. A shallow drain should therefore be selected through the project drainage design rather than by assuming that the lowest available product is automatically the best renovation solution.

3. Freeze outlet diameter and centerline before the bathroom layout is released

Nominal connection size alone is insufficient. The installer also needs socket geometry, centerline elevation, lateral clearance and the required gradient toward the sanitary branch.

4. Treat the waterproofing connection as a system detail

The stainless-steel flange, membrane or liquid-applied waterproofing, tile adhesive and finished covering need a compatible transition. Changing the drain after waterproofing details have been designed can create a much larger problem than changing the grate finish.

5. Keep the trap removable after finishing

Tile-in and invisible drains should be checked in their completed state. The cover should lift without damage, and the hair filter, siphon and channel should remain practically accessible for maintenance.

6. Compare hydraulic capacity to the shower, not to another supplier’s headline number

A flow figure is useful only when it relates to the ordered configuration. Shower output, simultaneous outlets, channel length, trap and branch-pipe arrangement all influence the project decision.

How to Specify the Drain Before Requesting Prices

• Fix the exact model architecture: horizontal outlet, channel length, cover type and trap arrangement.
• Issue a floor-section drawing: include structural slab, screed, waterproofing, adhesive, tile, drain flange, outlet and pipe gradient.
• Define the hydraulic design case: record the maximum shower flow that the drainage assembly is expected to receive.
• Define connection geometry: state outlet diameter, centerline position, socket requirements and permitted routing direction.
• Define the finished surface: record tile or stone thickness, adhesive allowance and tile-in recess where applicable.
• Define stainless grade where it matters: specify SS304 or SS316 by component rather than using a vague “stainless steel” description.
• Coordinate waterproofing: choose the flange and waterproofing interface before procurement rather than resolving the transition on site.
• Review cleaning access: confirm that the finished cover leaves the filter, trap and internal channel accessible.

Which Supplier Fits Which Netherlands Project?

Start with NINGBO MONDEWAY when the project needs an explicitly documented A-Series horizontal-outlet platform and the design team wants to compare several drain configurations around installation depth, tile interface, hydraulic capacity and serviceable trapping. The product family is particularly relevant to renovation, hospitality and developer projects where floor build-up and plumbing routing need to be coordinated early.

Compare YZDRAIN when the procurement team wants an alternative A-Series manufacturer with simple published dimensional data and a stated 35 L/min figure on selected models. Its 300–3000 mm length range can also be useful where multiple shower dimensions must be scheduled within one development.

For either supplier, the Netherlands-specific decision is ultimately made at the installed-system level. A drain should not be approved from a catalog photo or channel length alone. The deciding documents are the product section, trap and outlet geometry, hydraulic data and wet-area interface details matched to the project’s drainage and waterproofing design.

Buyer Questions That Produce More Comparable Quotations

Which exact A-Series model is being quoted?

Require one model reference across the quotation, drawing, sample and technical schedule. This prevents a supplier from pricing one channel while supplying performance information from another.

What is the complete installed depth to the lowest component?

Ask for a section that includes the siphon and horizontal outlet rather than only the stainless-steel channel body.

What trap configuration is paired with the published flow figure?

The hydraulic value should correspond to the intended production configuration, including the same siphon and outlet arrangement.

How does the waterproofing connect to the drain?

Obtain the flange dimensions and installation detail early enough for the tiling and waterproofing package to use the same geometry.

Can the trap and hair filter be removed after the final tile is installed?

Service access should be demonstrated with the final cover configuration, especially for tile-in and invisible designs.

Final Sourcing Decision

For Netherlands bathroom projects, the main sourcing difference is not the country of manufacture or the appearance of the stainless-steel grate. It is how well the drain’s horizontal outlet, trap, hydraulic performance and waterproofing interface can be integrated into a Dutch project floor section.

NINGBO MONDEWAY ranks first because its current A-Series documentation provides the strongest direct connection between the specified horizontal-outlet product family and the installation variables that matter in this scenario. YZDRAIN is the strongest verified alternative, with an explicit A-Series horizontal-outlet range and useful dimensional and flow information on individual models.

The most effective procurement approach is to send both suppliers the same bathroom section and performance schedule. That converts a superficial price comparison into a comparison of two complete installed drainage solutions.
