Extendable single handle shower bar made of stainless steel with matte black finish Delos by Imex

Matte Black Is Not Just a Color: It's a Design Statement

In recent years, matte black has established itself as the go-to finish for contemporary bathrooms that seek more than just functionality: they seek presence. Not the flashy presence of polished gold, nor the neutral coolness of chrome, but that serene visual impact that transforms every fixture into an element of deliberate composition. A matte black faucet doesn't go unnoticed, but it doesn't compete with the space either. It defines it.

The Imex Delos Collection Extendable Single-Lever Shower Bar in Matte Black Stainless Steel (ref. BDD055/NG) is designed with this premise in mind. A complete shower set—extendable bar, 20 cm circular overhead shower, round hand shower, single-lever mixer, 150 cm metallic hose, and integrated diverter—made of S304 stainless steel and brass, with a matte black finish applied with the aesthetic consistency required by a collection of this level.

This document details what the Delos set includes, what each specification means in practice, and why matte black is more than just a color choice.

Complete Technical Specifications

The Matte Black Finish: Why it Works and Why it Lasts

Matte black is probably the most demanding finish to produce with quality. A glossy black can tolerate minor imperfections in the surface layer without them being noticeable; matte black, lacking specular gloss to redistribute light, exposes any defect in the uniformity of the coating much more clearly. When a matte black finish looks good, it's because the manufacturing process supports it.

What is Matte Black Finish in Faucets?

In the case of the Delos set, the matte black finish is achieved by applying a dark colored surface layer to the brass of the faucet and the S304 stainless steel of the structural components. The matte finish—without specular gloss—is achieved by treating the surface layer so that it diffuses light instead of reflecting it in a concentrated manner.

The practical result of this finish is:

• Visually uniform and deep surface: without the light points that characterize polished surfaces, matte black appears as a continuous color plane that gives objects a solid and high visual density

• Remarkable resistance to fingerprints: unlike bright chrome surfaces, where every fingerprint is immediately visible, matte black significantly attenuates the visibility of contact marks. In an environment like the shower, where the product is touched with hands several times a day, this property has a direct impact on daily maintenance

• Effective concealment of water micro-splashes: water leaves white calcareous deposits when drying. On a white or light chrome background, these deposits are difficult to detect until they accumulate; on matte black, they are visible but also easy to remove with a dry cloth without the need for specific products

• Visual integration with dark materials: matte black dialogues with black ceramic, dark microcement, wenge wood, or black Marquina marble in a way that no other metallic finish can replicate

Matte Black in the Context of Current Bathroom Design

Contemporary bathrooms have evolved from the premise of "white and functional space" towards a conception of the bathroom as a room with its own character. In this context, dark finishes—and especially matte black—act as the elements that give visual weight to the space, counteracting the lightness of white or light coatings that are still predominant.

The Delos matte black set works especially well in:

• Bathrooms with white or light gray tiles, where matte black creates a sharp and modern contrast that avoids the monotony of a completely white space

• Bathrooms with cement or microcement in medium gray tones, where black intensifies the palette without leaving the same color range

• Bathrooms with dark wood on countertops, bathroom furniture, or floors, where matte black establishes an elegant tonal continuity

• Bathrooms with large format tiles in neutral tones, where the circular geometry of the Delos set softens the rigidity of the tile lines

• Black + white + wood combinations, which is one of the most popular schemes in current interior design and where matte black is the structuring chromatic axis

The Delos Collection: Circular Geometry in Black

The Delos collection by Imex adopts circular geometry as a coherent design language across all its visible components. The overhead shower is circular, the hand shower is round, and the bar profiles have a rounded cross-section. This formal coherence is a design decision with both aesthetic and practical implications.

Why Circular Geometry Matters in Black

In light finishes like chrome or white, the difference between a square and a circular showerhead might be perceived as a more or less neutral stylistic preference. In matte black, the difference is amplified: angular edges in black appear visually harsher and sharper; curved profiles in black maintain chromatic presence but express it with greater softness.

The circular geometry of the Delos collection, applied to matte black, results in a set that has presence and character without being aggressive. It is the combination that makes the Delos the right choice for bathrooms that want the visual impact of black without the harshness of angular geometries.

The 20 cm Ultra-Slim Circular Overhead Shower with Anti-Limescale System

The overhead shower of the Delos set has a circular shape, an ultra-slim profile, and a 20 cm effective diameter, made of S304 stainless steel and equipped with an anti-limescale silicone membrane system.

S304 Stainless Steel in the Matte Black Overhead Shower

One of the critical factors in any colored finish showerhead—black, gold, or any other—is what happens under the finish when the metal is continuously exposed to water, steam, and temperature changes. Showerheads made of zamak (zinc alloy) or coated plastic present a risk of internal corrosion that can manifest over time as blistering, flaking, or changes in the surface finish, regardless of the quality of the external coating.

The Delos overhead shower is made of S304 stainless steel, whose chromium and nickel alloy creates a passive protective layer that structurally resists corrosion, not just superficially. The matte black finish is applied to a base that does not deteriorate under domestic use conditions, ensuring that the appearance of the overhead shower is maintained long-term.

The Ultra-Slim Format: Why it Matters in Black

A bulky profile showerhead in black appears visually heavier and more dominant than the same showerhead in a light finish. The ultra-slim profile of the Delos overhead shower reduces its visual volume to a minimum, allowing the black to have presence through color and not through mass. The result is a visually clean showerhead that integrates into the bathroom composition without monopolizing it.

The Anti-Limescale System

Maintaining black accessories is a legitimate concern for any user considering this finish: the contrast between the black of the showerhead and the white limescale deposits is much more visible than on light chrome surfaces.

The anti-limescale silicone membrane system of the Delos overhead shower directly addresses this concern. Each nozzle is equipped with a small flexible silicone membrane that releases accumulated limescale deposits by simply running a finger over the surface of the showerhead. Maintenance to keep the matte black showerhead in perfect condition is reduced to a few seconds, without tools, without special products, and without disassembling.

The 150 cm Metallic Hose: A Noticeable Difference

One of the features that distinguishes the Delos set from other shower bars in a similar price range is its metallic hose—instead of the PVC hose that is standard in many sets.

Why the Metallic Hose Matters

The hose connecting the faucet to the hand shower is in permanent contact with hot water and is visible in the shower cabin throughout the useful life of the set. The differences between a PVC hose and a metallic hose are both functional and aesthetic:

Aesthetically: A PVC hose, regardless of whether it has a black outer finish, has an appearance that reveals it as plastic. The metallic hose has a visual presence that maintains coherence with the matte black finish of the rest of the set: the texture and light behavior on a metallic surface are completely different from those of PVC, and in a quality set, this difference is perceptible.

Functionally: The metallic hose is structurally more resistant to crushing and twisting than PVC. At the connection points and in the frequent bends that occur in daily use, the metal maintains its shape better than plastic. This translates into greater durability for the component that experiences the most movement in the set.

With matte black: The metallic hose in black is the only component that maintains real material coherence with the rest of the set. A visible black PVC hose next to a matte black brass faucet creates a material dissonance that users with an eye for detail will perceive.

The 150 cm length is the domestic standard for comfortable use: sufficient for the hand shower to reach all parts of the body and to rinse the shower cabin without restrictions, without the length being excessive and creating an obstruction in the space.

The 30 mm Single-Lever Ceramic Cartridge

The functional heart of the Delos set's faucet is the 30 mm single-lever ceramic cartridge. This component determines the precision of temperature control, the smoothness of handle operation, and the long-term durability of the system.

How the Ceramic Cartridge Works

The ceramic cartridge uses two alumina discs—a high-hardness technical ceramic—that slide over each other to regulate water flow. Alumina is one of the hardest materials existing in domestic applications, meaning that mechanical wear under normal use is practically nonexistent.

The practical consequences are three:

1. The faucet does not drip due to wear of the internal mechanism: faucets that develop dripping over time do so because their rubber gaskets or sealing elements deteriorate. The ceramic cartridge eliminates this structural point of failure

2. Temperature control is precise and predictable: handle movement produces gradual and reproducible temperature changes, without the abrupt jumps that characterize lower quality or worn cartridges

3. The feel of the handle does not change over time: the smoothness of movement felt when opening the faucet on the first day is the same that will be felt five or ten years later

The 30 mm Diameter

The Delos ceramic cartridge has a diameter of 30 mm, which is the standard for conventional domestic faucets. This diameter provides the appropriate control surface for precise adjustment and fluid operation in daily use.

The Brass Faucet Body

The body of the Delos set's faucet is made of brass—the copper and zinc alloy that is the reference material for quality faucets in the European market.

In the specific context of the matte black finish, the choice of brass as a base is particularly relevant. Brass allows for an adhesion and uniformity of the surface coating that alternative materials—zamak, ABS—cannot match. A matte black finish on brass has a depth of color and uniformity that is perceptibly superior to the same finish on other substrates.

Furthermore, brass has a density that translates into a perceptible solidity when operating the faucet handle. In a bathroom product used several times a day, this tactile solidity is a direct indicator of the set's construction quality.

The Integrated Diverter: Practical Convenience

The Delos set includes an integrated diverter that manages the water flow between the overhead shower and the handheld showerhead.

What the Diverter Enables in Practice

Without a diverter, switching between the fixed overhead shower and the hand shower requires turning the water off and on again, interrupting the shower and forcing you to readjust the temperature. With the diverter, switching is a one-step operation without interrupting the flow:

• For rinsing your body: fixed overhead shower

• For washing your hair with greater control: handheld shower

• For rinsing the shower screen or shower tray: handheld shower directed at the area to be cleaned

The integrated version of the diverter means that this mechanism is part of the set's structure without adding visible external components. The result is a clean visual line and a reduction in connection points susceptible to developing leaks in the long term.

The Height-Adjustable Holder

The height-adjustable holder for the hand shower allows you to position the hand shower at the height most comfortable for each user. This adjustability requires no tools: the holder slides along the bar and locks into the desired position.

In a family bathroom, this feature eliminates the need to compromise with a single permanent installation height. The same set serves with equal comfort for an adult of 1.80 m and a child of 1.20 m, simply by adjusting the position of the holder.

S304 Stainless Steel as the Basis of the Set

The extendable bar, shower head, and structural components of the Delos set are made of S304 stainless steel (AISI 304), the benchmark alloy for quality bathroom applications.

With a minimum content of 18% chromium and 8% nickel, S304 develops a passive layer of chromium oxide on its surface that:

• Resists corrosion in continuous exposure to water, steam, and household cleaning products

• Self-regenerates if the passive layer is mechanically damaged, always under oxidizing conditions

• Does not react with chlorine from treated water, which is a documented problem for many other metals in bathroom applications

This S304 base under the matte black finish is what ensures the long-term appearance of the set: the finish is not applied to a material that can deteriorate internally, but to a steel whose resistance is structural.

Flow Rate of ~12 Liters per Minute

The average flow rate of ~12 liters per minute provided by the Delos set is the standard value for a comfortable shower experience under normal household pressure conditions.

For a 20 cm circular shower head, this flow rate produces a water distribution dense enough to evenly cover the outlet surface and create a genuine rain sensation. At lower flow rates, large-diameter shower heads produce too dispersed a coverage; at much higher flow rates, water consumption increases without a proportional improvement in the experience.

In terms of water consumption, a 7-minute shower with the Delos set consumes approximately 84 liters — an efficient value for the caliber of the shower head and the experience it offers.

Installation Guide: What to Check Before Buying

The Delos set is a wall-mounted installation system that requires an existing or new recessed water outlet. The main points to check before installation are:

1. Wall water inlets: the single-lever faucet requires two inlets (hot and cold) with the standard 150 mm separation between centers. If there is an existing wall shower with a faucet, replacement is direct in most cases

2. Verticality of the bar: carefully mark the upper and lower fixing points to ensure perfect verticality. A slightly inclined bar affects both the operation of the extension mechanism and the aesthetics of the set

3. Fixing to tiles: use specific anchors and drill bits for ceramic. Seal the perimeter of the anchor plates with neutral silicone to prevent water infiltration behind the cladding

4. Hydraulic connection: apply Teflon tape to the threads of the water inlets to ensure watertightness. Check for leaks before finalizing the installation

⚠️ Installation by a qualified plumber is recommended for the water connection part. An incorrect connection can generate hidden leaks in the wall that are difficult and expensive to detect and repair.

Maintenance of the Delos Set in Matte Black

Matte black requires slightly different attention than chrome or gold finish. The basic guidelines for keeping the Delos set in perfect condition:

For the shower head:

• Regularly run your finger over the surface of the shower head to activate the silicone anti-limescale system and release limescale deposits before they accumulate

• Avoid leaving the shower head wet without drying after use in very hard water areas

• Do not use abrasive products or sponges that can scratch the matte black finish

For the faucet and bar:

• Clean with a damp cloth and dry with a soft cloth after cleaning

• Avoid cleaning products containing acid, bleach, or abrasives

• Neutral cleaning products or those specific for stainless steel are fully compatible with the matte black finish

For the metal hose:

• Avoid forced bends at very sharp angles that can fatigue the metal

• Clean with a damp cloth and dry to remove limescale deposits on the outer surface

With this basic maintenance, the Delos set will maintain its original appearance throughout its useful life.

Comparison: Delos vs LINE — same black, different collections

For those evaluating between different black shower bars from Imex, the most relevant comparison is between the Delos collection (this product) and the LINE collection in black:

The main difference between both collections is the type of black finish and the hose: the Delos uses matte black with a metal hose; the LINE uses brushed black with a PVC hose. For bathrooms seeking the complete opacity and depth of black, Delos is the choice; for bathrooms that prefer black with a slight satin finish and visible micro-scratches, LINE would be more suitable.

About the Delos Collection and the Imex Brand

Imex is a Spanish manufacturer specializing in faucets, shower systems, sanitaryware, and bathroom accessories with decades of presence in the European market. The Delos collection represents its line of wall-mounted shower sets oriented towards contemporary design bathrooms that opt for matte black as the reference finish.

The 5-year warranty that Imex offers on the products in this collection reflects the manufacturer's confidence in the durability of the materials and the constructive quality of the set. In the faucet and shower system segment, warranties from manufacturers with less industrial robustness are usually limited to 1-2 years; Imex's 5 years represent a significantly higher standard that has real implications for spare part availability and long-term technical service.

What Type of Bathroom is This the Right Choice For?

The Delos matte black set is the right choice if:

• Your bathroom has a contemporary visual language where black is the structuring finish for accessories

• You want the complete depth and opacity of matte black, without shine or micro-scratches

• You value a metal hose that maintains material consistency with the rest of the set

• You need a complete system — shower head, hand shower, bar, faucet, hose — coordinated in a single black finish

• Your installation has a wall water outlet and allows for the installation of a complete shower set

Consider other options if:

• You prefer brushed black (with visible micro-scratches) instead of matte black → the LINE model in black

• You want the same circular design but in brushed gold → the LINE model in brushed gold

• You prefer angular geometries (square shower head, square hand shower) → Imex's ART collection in black or gold
