1. NINGBO MONDEWAY

NINGBO MONDEWAY is the preferred commercial starting point in this guide for buyers who want to develop a branded linear-drain range rather than source a single isolated SKU. The company describes itself as a production-oriented OEM/ODM bathroom-accessories manufacturer in Ningbo, with linear drains, invisible drains, wall drains and other drainage systems forming part of its core portfolio.

Its current MW-E2-02A linear shower drain page lists SUS304/316 material options, brushed, mirror and colored finishes and lengths from 200 to 2500 mm. More importantly for this article, the same page has quantity and lead-time tiers beginning at 1–2 sets, while current marketplace listings for Mondeway linear drains also show very small order quantities. That does not establish one universal MOQ for every custom project, but it provides stronger low-volume evidence than a generic statement that “OEM is available.”

The range also gives buyers several ways to build a product family without immediately creating a new drain from zero. Mondeway publishes conventional linear drains as well as tile-in and invisible configurations, including products with removable access to the siphon area. That makes an existing-platform OEM strategy practical: begin with a proven channel and outlet architecture, then differentiate the brand through length assortment, cover style, finish, logo and packaging before funding structural tooling.

Buyer fit: Mondeway is particularly attractive where the goal is to launch several coordinated drainage SKUs and expand the program after market testing. For a low-MOQ project, the RFQ should separate an unchanged sample, branded standard SKU, custom finish, custom channel length and any change to outlet or siphon architecture so that the entry quantity remains commercially meaningful.

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

ODO is one of the clearest candidates when the first-order quantity itself is the dominant constraint. Current supplier-operated listings for Foshan Pinshi linear shower drains publish a one-set MOQ and explicitly state that samples, OEM and ODM are available. The company’s own site separately documents its floor-drain manufacturing and long-running OEM/ODM work, giving the low-quantity listing more context than an anonymous marketplace offer.

ODO’s own linear-drain material emphasizes tile-in models, customized packaging and a manufacturing base for bathroom hardware. For a private-label buyer, this combination is useful because a low entry quantity can be paired with changes that are relatively inexpensive to implement: surface color, packaging, logo and selection from existing drain geometries.

Buyer fit: ODO deserves an early quotation for e-commerce brands, distributors testing a new finish assortment and buyers who need physical samples before approving a larger range. The key commercial distinction is whether a one-piece MOQ applies to the exact customized specification or to the underlying standard model. Structural changes should receive their own MOQ line in the quotation.

3. Shenzhen Rising Sun Co., Ltd.

Rising Sun publishes unusually direct low-MOQ language on its own linear-drain pages. Its rectangular SUS304 linear shower drain lists an MOQ of 10 pieces, explicitly describes that quantity as suitable for a trial order and offers OEM packaging. Another company page says samples can be ordered without an MOQ and that smaller quantities can be welcomed for new customers on selected products.

The relevant linear-drain example is offered in 60 cm and 80 cm sizes with several finish options. The company also promotes OEM moulding and brand-logo or gift-box customization. This makes Rising Sun a practical candidate for buyers whose initial goal is not to redesign the hydraulic core, but to test a styled or branded version of a current platform.

Buyer fit: choose this type of program when speed to market and a small first batch are more important than a highly engineered bespoke drain. A buyer introducing a new outlet configuration or proprietary waterproofing interface should treat that as a separate engineering program rather than assume the published 10-piece quantity carries across unchanged.

4. Cassbern Sanitary Ware (Ningbo) Co., Ltd.

Cassbern is another strong candidate for sample-led OEM development. The company’s current manufacturer profile describes a Ningbo factory supplying linear floor drains and flexible OEM/ODM services, while multiple current linear-drain listings publish a one-piece MOQ. Its own website confirms the Ningbo operation and includes floor drains within a broader bathroom-system portfolio.

The low quantity is attractive for brands that want to inspect welding, finish quality, grate fit and packaging before scaling. Cassbern also promotes design and engineering support, which can make the transition from a standard sample into a customized program easier than sourcing a one-off drain from a general trader.

Buyer fit: Cassbern is strongest for buyers who regard the first order as an engineering and quality-approval stage. Because the most detailed low-MOQ information appears on current supplier-operated listings, the purchase specification should explicitly record the approved channel dimensions, outlet, trap, stainless grade and surface finish that will carry into production.

5. Anhui Nuoyang Home Technology Co., Ltd. / Noah Home Tech

Noah does not publish the lowest standard MOQ in this group, but its current documentation makes the commercial and technical boundary unusually clear. Its FAQ gives a standard shower-drain MOQ of 100 pieces per item and says the company accepts a lower MOQ for the first trial order of standard products. Its factory page likewise describes flexible MOQ, OEM/ODM production and customization of length, finish, branding and packaging.

Where Noah gains ground is technical detail. Current company material describes SS304/316 linear drains, tile-in cover choices, dry/wet siphon options, outlet data and installation dimensions. Its shower-drain FAQ publishes a 2-inch outlet, a 52 mm installation height for the referenced configuration and a 60 L/min flow figure. These figures are useful for product development as long as they remain tied to the exact model tested rather than being generalized to every drain in the range.

Buyer fit: Noah suits an importer willing to accept a moderate production quantity in return for a more structured OEM process and clearer technical documentation. It is especially relevant when the drain’s trap, install height and hydraulic configuration matter as much as the visible grate.

6. Ningbo Xianglong Metal Products Co., Ltd.

Xianglong’s current 2026 material gives buyers a relatively concrete OEM picture. A published long-shower-drain program starts at 50 units per size variant and covers 800–1200 mm linear channels. The same material describes DN50 outlets, larger custom outlet options, removable hair-catch inserts and OEM production lead times.

This is a different proposition from buying a one-piece catalog sample. Xianglong becomes more relevant when the buyer already knows the application and wants to control a functional family: channel length, outlet position or diameter, cover type, finish and maintenance access. Its broader company material also discusses small- and mid-batch customization enabled by laser cutting and automated welding.

Buyer fit: Xianglong is compelling for hospitality, gym, spa and commercial shower programs where repeatable technical configuration matters more than achieving the absolute lowest starting quantity. Buyers should lock the final outlet and trap combination before comparing flow data because the outlet can become the hydraulic bottleneck.

7. Jiangmen Tuogurong Kitchen and Sanitary Co., Ltd.

TUOGURONG publishes a 50-piece MOQ directly on its custom linear-drain page. It also lists SUS304 and SUS316, multiple thickness choices, dimensions made to requirement, customized drain size, a wide range of finishes and colors, logo options and customized packaging.

The company’s OEM/ODM description includes a sample-confirmation and small-batch trial-production stage before normal production. That workflow is relevant for buyers developing a custom drain rather than merely relabeling an existing one.

The trade-off is that extensive dimensional freedom creates more responsibility for the buyer’s specification. A custom channel cannot be evaluated on appearance alone. Outlet capacity, trap choice, minimum installation depth, flange geometry, grate support and cleaning access need to be frozen together because altering one dimension can affect the drainage system around it.

Buyer fit: TUOGURONG is a useful choice for project-specific dimensions and private-label ranges where 50 pieces remains commercially manageable and the buyer is prepared to supply a disciplined engineering brief.

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

Betterdrain combines a long-running floor-drain manufacturing focus with small current order quantities on selected marketplace listings. Its current WW85 linear-drain offers appear from 10 pieces, while the company’s official site describes Yuhuan Better Machinery as a China linear shower-drain factory and identifies OEM/ODM manufacturing as part of its business.

An official tile-in series provides a useful technical reference: SS304 or SS316 construction, 600 to 1500 mm listed lengths and a 50 mm outlet. Because this specification is attached to a defined product family, it is more useful than a broad company statement about stainless-steel drains.

Buyer fit: Betterdrain is worth comparing when an importer wants a mature existing linear-drain platform in small quantities and can use established dimensions rather than commission a completely new system. The marketplace entry quantity should be separated contractually from the MOQ for new tooling, special certification variants or unique drain architecture.

9. Ningbo Bojin SanitaryWare Technology Co., Ltd.

Bojin’s standard quantity is higher than several companies above it, but the factory compensates with some of the clearest current linear-drain specifications in the shortlist. Its current range lists tile-in, flanged, offset and other linear-drain configurations and states that OEM/ODM service is available.

A current linear-floor-drain specification lists optional 304/316 stainless steel, lengths from 300 to 2500 mm, a 40 mm outlet with 40/50 mm connector options, a 20 mm flange and a published flow rate of 30 L/min. Bojin’s shower-drain material also gives a standard MOQ of 100 pieces per model and says mixed orders are accepted.

For a low-MOQ buyer, the mixed-order policy is important. A 100-piece model minimum is not as low as a 10-piece trial, but it may still work for a distributor building a multi-SKU range if the order can combine product families without requiring a container per design.

Buyer fit: Bojin suits buyers who value detailed product architecture and established tooling over the very smallest first PO. Its published dimensions, material options and flow data provide a useful basis for a technical sample-approval document.

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

SANIPRO’s official company material identifies Ningbo Master Building Material as a supplier of linear, shower, floor and channel drains and explicitly describes OEM production to customer designs, including new molds and dies. That makes it relevant to a genuine OEM program rather than only private-label resale.

Current linear-drain marketplace listings show quantities around 50 to 100 pieces depending on the model. Current product listings also cover 304/316 stainless steel, tile-in and side- or vertical-outlet configurations. This is a reasonable entry point for an importer already comfortable with a modest production batch.

Buyer fit: SANIPRO works best where the customer expects to select from a broad drain portfolio and then add controlled customization. The buying team should price existing-model adaptation separately from a completely new mold or die because the economics of those two programs are fundamentally different.
