How to design a contemporary bathroom: sinks, tapware and sanitaryware
Sinks, tapware and sanitaryware are often selected separately. The final result, however, depends on the relationship between these elements. The sink establishes heights and volumes, the faucet must work with the shape and depth of the bowl, while the sanitaryware affects the visual continuity between the wall and the floor.
Understanding how to design a contemporary bathroom therefore means considering dimensions, plumbing, finishes, maintenance and everyday habits together. There is no single configuration that is always better: there is only the one that best suits the available space and the way the bathroom will be used.
Before choosing products: understand the space correctly
The design process should begin with an accurate survey. The size of the bathroom, door openings, windows, circulation space, niches and recesses determine how much room is actually available.
The position of waste pipes, water connections and WC cisterns must also be checked, together with the structure of the walls. Concealed faucets or wall-hung toilets may require service walls, support frames and building work that reduce the available depth.
It is also important to distinguish between actual and perceived dimensions. A wall-hung element leaves the floor visible and can make the composition appear lighter, but it does not necessarily occupy less space. Likewise, well-proportioned back-to-wall sanitaryware can create a compact and visually ordered result.
At this stage, consulting a professional can help you assess the floor plan, technical constraints and everyday requirements correctly. Domus Habitat offers the experience gained over 50 years in the sector, including a dedicated VideoCall with its architects.
Countertop or wall-hung sinks: where the design begins
A countertop sink introduces two overlapping volumes: the bowl and the surface beneath it. It allows different materials to be combined and preserves usable space around the sink, but the overall height must be carefully assessed.
With the Antonio Lupi Nabatei NBT060C countertop sink, measuring 10 cm in height and 60 cm in width, it is important to provide a well-proportioned surface with enough room for the faucet and easy cleaning.
A wall-hung sink creates a composition centred on the wall and leaves the floor clear. The Galassia Ceramica Lola 7501, measuring 50 cm in width, can be used in a compact bathroom without necessarily adding a cabinet of the same size. Its depth and the position of the trap must, however, be checked against the available circulation space.
The Agape Bjhon 2 freestanding sink, with floor drainage, removes the need for a cabinet or countertop. It creates a self-contained composition that emphasises the volume of the sink while keeping the wall clear.
All dimensions should always be checked against the product data sheet and confirmed with the designer and installer.
The relationship between sink and tap
Faucets should not be selected on the basis of finish alone. Spout height, projection, water flow position and basin depth all affect usability and splashing.
A tall faucet such as the Gessi Rilievo 59010 can be paired with a countertop sink, provided that the spout reaches the bowl correctly.
Wall-mounted faucet, such as the Gessi Inciso 58088, leaves the countertop clear. However, the concealed installation height, distance from the basin and point at which the water enters the bowl must be established in advance.
Tapware: material, treatment and finish
Brass, stainless steel and PVD do not refer to the same characteristic. Brass and steel may be the base material; polished, satin, brushed and matt describe the appearance of the surface; PVD is a treatment applied to the material.
The CEA Design Ziqq ZIQ39, for example, is made from AISI 316L stainless steel and is available in different surface treatments and finishes.
The choice should take into account frequency of use, hard water, cleaning habits and the manufacturer's instructions. Polished surfaces make water marks and fingerprints more visible, while dark finishes can emphasise limescale. Satin or brushed finishes may make some marks less noticeable, but they still require correct maintenance.
Coordinating a bathroom does not mean repeating the same colour throughout. Taps, shower profiles, accessories, handles and lighting can create continuity or a controlled contrast. The result becomes confused when too many metallic finishes are introduced without a clear hierarchy.
Wall-hung or back-to-wall sanitaryware
Wall-hung toilets is fixed to the wall and remains raised above the floor. Back-to-wall toilets rests on the floor but sits flush against the wall. The two terms are not interchangeable.
The Antonio Lupi Komodo wall-hung WC, rimless and complete with a soft-close seat, keeps the floor clear and gives the composition a lighter appearance. It does, however, require a concealed cistern, a suitable support frame and a compatible wall structure.
The NIC Design Milk 003716 is a back-to-wall floor-standing toilet. It may be easier to integrate into certain renovation projects, particularly when the position of the existing waste pipe makes a wall-hung solution less practical.
The toilet flush plate also forms part of the design. The Gessi Origini 54611, compatible with Geberit Sigma cisterns, can be coordinated with the tapware and accessories, but technical compatibility with the flushing system must take priority over the finish.
How to coordinate sinks, fauct and toilets
In a compact bathroom, a wall-hung sink, streamlined tapware and shallow toilets can help avoid an excessive accumulation of volumes.
In a more material-led bathroom, a countertop sink can be paired with a substantial vanity unit and tall or wall-mounted faucets. Toilets with fuller shapes and a carefully selected metallic finish can complete the composition without making every detail identical.
In a bathroom used frequently, storage, ease of cleaning and surface resistance become more important. Enough space should be left around the sink, finishes should suit the characteristics of the water and plumbing components should remain accessible.
In less invasive renovations, existing waste pipes and water connections may influence the design more than the preferred style. Adapting the product selection to the existing plumbing can prevent unnecessary work.
A design mistake to avoid
Visual compatibility does not guarantee technical compatibility.
A tap may match the finish of the flush plate but still be unsuitable for the basin. A WC may look consistent with the overall design but be incompatible with the waste connection or cistern.
Before purchasing, product data sheets, model codes, dimensions, concealed components and plumbing requirements must be checked. Domus Habitat's design service allows these aspects to be assessed with its architects, while also providing clearer information for the professionals involved in the work.
The factor that is often overlooked
A bathroom should be designed for real everyday use, not only to look tidy in photographs.
The number of users, the presence of children, storage requirements, cleaning frequency and hard water all affect the priorities. A main bathroom used every day requires different considerations from a guest bathroom.
From product selection to a complete design: rely on our experts
The sink defines heights and volumes, the faucet must be proportioned to the bowl, and the toilet must work with the available space and plumbing. For this reason, each individual choice should begin with an overall vision of the bathroom.
