Single lever extendable stainless steel shower bar brushed gold finish Art by Imex

Why the Choice of Shower Bar Defines the Complete Bathroom Experience

The shower bar is one of the most underutilized elements in bathroom design: it is often bought as an accessory, almost as an afterthought, yet it is the component that most directly impacts the daily use of the space. The quality of the flow, the ease of temperature regulation, the height of the shower head, the flexibility of the hose, the durability of the finish against steam and cleaning products... all of this depends on what you choose when you select a shower bar.

The Imex Art Single-Lever Extendable Shower Bar in S304 Stainless Steel with Brushed Gold Finish (model ART IMEX, ref. BDAR025OC) is designed to address each of these factors through its construction quality and aesthetic coherence. This document details what the set includes, what each technical specification means in practice, and for what type of bathroom and user it is the most suitable choice.

Technical Specifications of the Set

The Brushed Gold Finish: Aesthetics and Functionality

The brushed gold finish is one of the most prominent finishes in contemporary mid-to-high-end bathroom projects. Its popularity is not only aesthetic: it also responds to specific functional properties that differentiate it from both standard chrome and the glossy gold finishes of previous decades.

What is a Brushed Gold Finish?

Brushed gold is a surface finish obtained by applying a metallic layer—in this case, over brass and stainless steel—which is then subjected to a mechanical brushing process in a single direction. This process creates a satin texture with visible parallel micro-grooves, producing a warm yet restrained visual effect, distinct from the specular shine of classic gold.

The result is a finish that:

• Diffusely reflects light, avoiding aggressive glare that can be dominant in small spaces.

• Conceals fingerprints and water splashes more effectively than polished surfaces, significantly reducing the frequency of cleaning needed to maintain a pristine appearance.

• Ages more gracefully than glossy gold, without the loss of aesthetic presence often associated with standard chrome finishes over time.

• Integrates easily with material combinations such as white marble, gray microcement, natural wood, terracotta or toasted ceramic tones, and bottle green or matte black coverings.

In the context of the current trend toward warm, organic bathrooms with noble materials, brushed gold functions as the chromatic axis that unifies the space without being ostentatious.

S304 Stainless Steel: Why Material Matters in the Shower

The shower bar body, shower head, and hand shower are made of S304 stainless steel (also known as AISI 304 or 18/8), which is the most widely used alloy in bathroom and kitchen applications requiring continuous resistance to humidity.

Composition and Properties

S304 stainless steel is an iron alloy with a minimum content of 18% chromium and 8% nickel. This combination produces a passive chromium oxide layer on the material's surface that:

• Acts as a barrier against corrosion, even with prolonged contact with water, steam, and chlorinated agents.

• Does not react with common cleaning products, allowing the use of standard cleaners without degrading the finish.

• Will self-regenerate if the passive layer is mechanically damaged, provided the environment is oxidizing (such as air and water).

In the context of a shower, where metal is exposed to continuous cycles of humidity and temperature, the choice of S304 over zinc alloys (zamak) or coated plastic is crucial for the product's longevity. Systems made of zamak present a much higher risk of internal corrosion in continuously wet environments, regardless of the quality of the exterior finish.

The Extendable Bar

The bar itself is the component that determines the height range at which the shower head assembly can be positioned. Being extendable, it adapts to different installation heights and different usage needs within the same family—from children to tall adults—without the need to fix a permanent height. The extensibility also facilitates installation in cabins or shower areas where the distance between the fixing point and the optimal use position does not match a standard measurement.

The Square Ultra-Flat Shower Head: Design and Features

The shower head included in this set has a square, ultra-flat profile, with an effective diameter of 20 cm, made of stainless steel and equipped with an anti-limescale system.

Why the Square Format?

In recent years, the square shower head has supplanted the circular one as the dominant option in contemporary design bathrooms. The reason is visual coherence: modern shower spaces—with rectangular screens, square shower trays, and large-format coverings—integrate better with angular geometries. A 20 cm square shower head functions as a visually neutral element in that context, compared to the tension that a circular element can generate in an environment dominated by straight lines.

Why the Ultra-Flat Format?

The ultra-flat profile minimizes the visual volume of the shower head. In smaller shower enclosures, where every centimeter of free space is valuable, a thin-bodied shower head contributes to making the shower area appear more spacious and less cluttered. It also facilitates cleaning of the shower head itself, by eliminating the nooks and accumulation surfaces that more voluminous designs have.

The Anti-Limescale System

The anti-limescale system is a functional feature that directly affects maintenance. The injectors of shower heads—the small holes through which water exits—are prone to limescale accumulation in areas with hard water. In a shower head without an anti-limescale system, this accumulation is visible and requires regular descaling of the injectors to maintain uniform water distribution.

The silicone button anti-limescale system—present in this shower head—works differently: each injector is surrounded by a small flexible silicone button or membrane that, simply by running a finger over the surface of the shower head, releases accumulated limescale deposits. Maintenance becomes a matter of a few seconds, without the need for tools or specific products.

The Single-Lever Faucet: The 35 mm Ceramic Cartridge

The faucet is the most critical component from a functional point of view: it is the mechanism that controls water flow and temperature, and it is also the one that accumulates the most mechanical wear over the lifespan of the unit.

What is a Ceramic Cartridge?

The 35 mm ceramic cartridge is the internal mechanism of the faucet that regulates water flow. Unlike rubber cartridges or ball systems, the ceramic cartridge uses two alumina discs—a high-hardness technical ceramic—that slide over each other to open, close, and mix hot and cold water flows.

The practical advantages of this system are:

• Precision in temperature control: angular movement of the handle produces gradual and predictable temperature changes, without the abrupt jumps characteristic of worn cartridges.

• No dripping due to wear: the hardness of the ceramic discs makes them virtually immune to mechanical wear under normal household use. Faucets that drip over time do so because their rubber seals deteriorate; the ceramic cartridge eliminates that point of failure.

• Minimal maintenance: unlike conventional systems, the ceramic cartridge does not require periodic lubrication or adjustments.

• Smooth and consistent feel: the action of the discs produces a smooth handle movement that does not change over time, maintaining the same tactile response throughout the cartridge's lifespan.

The 35 mm diameter is the quality standard for intensive-use faucets: cartridges with smaller diameters have higher internal hydraulic resistance and lower durability under frequent opening and closing cycles.

The Brass Body

The faucet body is made of brass, not zamak or plastic. Brass is the copper and zinc alloy that has been the reference material for bathroom faucets for over a century, for reasons that remain completely valid:

• High corrosion resistance in humid environments and with chlorinated water.

• Precise machining: brass allows for tight dimensional tolerances, ensuring the quality of the internal seal and preventing long-term leaks.

• Compatibility with all quality surface finishes, including the PVD brushed gold that covers this model.

• Density and weight that convey solidity and perceived quality when operating the handle.

The Square Hand Shower and the Adjustable Holder

Square Hand Shower

The square design hand shower is the portable element of the set – the handheld shower that is held to direct the water jet. Its square format maintains visual consistency with the shower head and the overall aesthetic line of the set. The modern design of the hand shower is also intended for a comfortable and secure grip even with a wet hand.

Height-Adjustable Holder

The hand shower holder is height-adjustable along the bar. This means that the parking position of the hand shower when not in use can be adjusted without tools to each user's preferred height, and changed at any time. In a bathroom shared by people of different heights, this adjustability eliminates the need to compromise with a single fixed position.

The Hose: 150 cm PVC Hose

The hose — which connects the faucet to the hand shower — is 150 cm long and made of quality PVC.

150 cm is the standard length for comfortable domestic use: enough to maneuver the hand shower in any position within the shower cabin or area, including using it to rinse the cabin itself. A shorter length would limit the range of action; a longer one would introduce the risk of the hose falling to the floor or creating an obstacle in the space.

The PVC material ensures lasting flexibility without the hardening that affects some lower quality hoses over time. The termination at both ends with standard connections ensures compatibility with the components of the set and the possibility of replacement if necessary.

Flow Rate: 12 Liters Per Minute

The average flow rate of 12 liters per minute offered by this set is the reference value for a comfortable shower experience under standard domestic pressure conditions. This value represents a balance between:

• Body coverage: a flow rate below 8-9 l/min feels noticeably weak in a 20 cm shower head, diluting the rainfall sensation.

• Water efficiency: flow rates above 15-16 l/min consume water disproportionately without proportionally improving the experience.

• Compatibility with domestic installations: most domestic water installations are dimensioned for flow rates in this range without noticeable pressure drops.

In practical terms, a 7-minute shower with this set consumes approximately 84 liters—a reasonable and efficient value for the shower head's caliber.

Installation: What to Know Before Buying

This shower bar is designed for wall installation, as part of a wall-mounted shower set. The fixing system includes supports to anchor the bar at two points on the wall—upper and lower—through which the water connection also runs.

Pre-installation considerations:

1. Water connection: the single-lever faucet requires a wall-mounted water outlet with standard separate hot and cold water inlets. If you currently have a wall-mounted shower with an existing faucet, replacement is direct in most cases.

2. Distance between fixings: verify that the distance between the wall fixing points is compatible with the extendable range of the bar before drilling.

3. Wall type: fixing on tiling requires specific plugs and screws for ceramic, different from those used in masonry or plaster.

4. Sealing: apply neutral silicone around the perimeter of the anchor plates to prevent water infiltration behind the tiling.

Installation by a qualified plumber is recommended, especially for the connection to the water supply. The installation of the bar itself is accessible for a DIYer with basic experience.

The 5-Year Warranty

The Imex Art set includes a 5-year warranty against manufacturing defects, subject to use in accordance with the manufacturer's instructions. This warranty covers:

• Failures in the ceramic cartridge under normal domestic use.

• Defects in the surface finish not attributable to abrasive cleaning products.

• Structural failures in the components of the set

The 5-year warranty is a significant indicator of the manufacturer's confidence in the product's build quality: in the faucet and shower market, warranties from lower-quality manufacturers are often limited to 1-2 years.
