Product Description
Matte Black, Two Installation Choices
The BD-A21B in matte black gives you the flexibility to choose how the drain integrates with your bathroom floor — either as a visible design element with its solid matte black face, or as a seamless feature by inserting a piece of floor tile into the recessed cover. One drain, two aesthetics.
Solid Cover — Matte Black
The primary face is a solid matte black stainless steel panel. The matte finish gives it a bold, contemporary look that works with most bathroom finishes — from concrete and stone to tile and plaster. Unlike polished chrome or mirror finishes, the matte black doesn’t show water marks and fingerprints as readily.
Tile Insert — Seamless Floor Integration
Flip the BD-A21B’s cover to reveal the tile insert recess. Cut a piece of your floor tile — marble, limestone, polished concrete — to fit the recess, and the drain becomes nearly invisible in the floor. This is the choice for minimalist wet rooms, curbless showers, and contemporary bathrooms where a continuous floor surface is the design goal.
Dual-Function — Practical Flexibility
The BD-A21B’s double-sided design means you can make the installation choice on-site, after you’ve seen the floor tile in place. If the design evolves mid-project or the client changes their mind on the finish, the drain specification doesn’t need to change — you simply choose the appropriate face.
Wide Coverage, Low Profile Linear Format
At 1000mm length and 100mm width, the BD-A21B handles the water volume of large showers and open wet room configurations without the visual weight of a traditional point drain. The low profile sits flush with the floor, meeting the accessibility requirements of curbless and level-access showers.
SUS 304 Stainless Steel — Specified for Wet Environments
The BD-A21B body is constructed from SUS 304 stainless steel, with a flange and channel system designed for continuous water exposure. The material specification and the precision-machined seal are what differentiate a quality linear drain from budget alternatives that fail at the seam between drain body and cover.

FAQ
Q: Can I install the BD-A21B without using the tile insert function?
A: Yes. The BD-A21B is designed so the solid matte black face can be used as the finished cover without any tile. Simply flip to the solid face and install — the tile insert option is there if you want it, not mandatory.
Q: What tile types work with the tile insert?
A: The tile insert recess accommodates most stone and porcelain tiles from 8-12mm thick. Natural stone tiles (marble, travertine, slate) and porcelain tiles are the most common. Confirm the recess depth with your tile contractor before selecting the BD-A21B for very thick or very thin tiles.
Q: What is the difference between the BD-A21B and BD-A21C?
A: The BD-A21B and BD-A21C share the same dual-function tile insert design. The difference is finish: BD-A21B is matte black, BD-A21C is brushed gold. Choose based on the bathroom’s metal finish specification.
Q: Does the matte black finish require special cleaning?
A: No. The matte black finish is low-maintenance — water marks and fingerprints are less visible than on polished or mirror finishes. Clean with warm water and a soft cloth; avoid acidic or abrasive cleaners which may damage the PVD coating over time.
Q: How is the BD-A21B installed in a concrete floor?
A: The BD-A21B is typically installed during the screeding stage — the drain body is set to the correct height and falls, with the floor tile laid to meet the drain’s top surface. The tile insert recess provides a clean edge for the tile cutter to work to. Detail the connection to the waterproofing membrane per the installer’s standard wet room waterproofing specification.
Choose Your Finish on Site — Matte Black, Seamless, or Both.
The BD-A21B’s dual-function design means the bathroom specification doesn’t need to be locked in before you see the tile. A visible matte black feature, or a seamless floor-integrated drain — one product, decided on site.
