How to combine bath and shower in a small space

Configuration ideas for small spaces

In contemporary bathrooms, the question of space is often crucial. Fortunately, a number of ingenious configurations make it possible to integrate both a bath and a shower, even in the most confined spaces.

Designing a small bathroom requires creative solutions to maximize every available square centimetre. Among the most effective options is the bath/shower combination, which offers remarkable versatility without compromising comfort.

To make the most of limited space, several configurations are particularly suitable. The corner bath, for example, is easily installed in a corner to free up floor space. It uses areas of the bathroom that are often under-utilized, optimizing the layout of the room. This solution is ideal for bathrooms with atypical dimensions.

The asymmetrical bathtub is also an excellent alternative for small spaces. Narrower on one side, it optimizes the use of every square centimeter while maintaining optimum comfort.

Integrated bath/shower solutions represent a particularly relevant option for smaller bathrooms. This equipment integrates a bathtub and shower in the same space, usually with a glass shower screen or sliding wall to prevent splashing. This allows you to enjoy a quick shower and a relaxing bath without taking up too much space.

For long spaces, a configuration with the bathtub against one wall and a walk-in shower at the other end can work effectively. According to several plans analyzed, this layout is viable even in bathrooms of just 4 m². The use of a glass wall between the two spaces maintains a feeling of openness.

Corner bath/shower combinations are another interesting option, particularly suited to small, square bathrooms. They fit perfectly into the corners of rooms and make efficient use of available space. This configuration can be complemented by wall-mounted storage units to maximize the use of vertical space.

In terms of layout, there are a few key principles that can be applied to further optimize space. Favoring suspended equipment (such as toilets, washbasins and furniture) frees up floor space and facilitates cleaning. The use of sliding rather than swinging doors avoids clearance problems and saves precious space.

To visually create more space, glass walls and mirrors are invaluable allies. A large-format mirror strategically placed on a wall can visually double the space. Similarly, transparent shower enclosures with very thin or non-existent profiles allow the eye to wander freely, enhancing the impression of space.

Preparing for installation in a small space

Installing a bath/shower combo in a small space requires careful preparation to avoid unpleasant surprises. Even before you buy your equipment, there are several essential steps to take to ensure harmonious, functional integration.

Measure and plan the layout

Before installing a bath/shower combination, it's essential to take precise measurements of the bathroom. These include the total surface area available (length, width, ceiling height), the position of doors and windows and their clearances, the position of water inlets, and any structural constraints such as columns or protruding corners.

Once these elements have been noted down, the production of a scale plan - on graph paper or using 3D design software - enables different configurations to be explored. In general, a standard bath/shower combo requires a minimum of 170 cm long by 70 cm wide, with 60-70 cm of circulation space at the front for optimum comfort.

Corner models are also an excellent option for small, square bathrooms. They adapt to surfaces ranging from 80×80 cm for the most compact to 140×140 cm for the most generous versions.

Check the water supply and drainage system

Plumbing plays a key role in the installation of a bath/shower combination. Before making any purchase, it is essential to check several points:
- the position of the hot and cold water inlets, ideally 110 cm from the floor; 
- the diameter and location of the drain, generally 40 mm for a bathtub; 
- the available water pressure, with a recommended minimum of 3 bars for comfortable use.

If the existing connections don't match the location of the future equipment, there are two possible solutions: adapt the layout or call in a plumber to relocate the inlets and outlets.

It's also important to ensure that the drain slope is at least 1 cm per metre, to guarantee a smooth flow. In certain configurations, such as with integrated walk-in showers, it may be necessary to install a lifting system.

Choosing the right enclosure: fixed, pivoting or folding

Choosing the right shower enclosure is crucial to optimizing space in a small bathroom. Several options are available:

• The fixed wall: simple and elegant, it doesn't encroach on space, but offers limited protection against splashes. It's relatively easy to install and generally affordable. However, it can sometimes complicate access to the bathtub.
• The pivoting wall: more flexible, it provides easy access to the bathtub while offering good protection against splashing water. However, it does require a certain amount of clearance, which should be taken into account when planning.
• The folding wall: particularly suited to very small spaces, it folds up against the wall when not in use. This solution combines practicality and space-saving, but may be slightly less watertight than other options.

For really tight spaces, folding or sliding walls optimize every available centimeter. Clear tempered glass models (minimum thickness 8 mm) offer the added advantage of not visually "cutting through" the space, creating a sensation of volume.

Finally, whatever your choice, don't forget to check the compatibility of the wall with your bathtub model, and to plan its installation in relation to technical constraints such as the presence of radiators or switches.

Tips for creating a feeling of space

Designing a small bathroom space isn't just about technical issues. Creating a feeling of space in your bathroom with a bath/shower combo also involves visual tricks that can radically transform the perception of your room.

Use a glass wall for more light

Light is the indispensable ally of small spaces. A glass wall for a bath/shower combination goes beyond mere practicality: it becomes a real lever for visual enlargement.
Transparent tempered glass panels provide visual continuity that avoids any break in the field of vision, giving the illusion of an enlarged space. To accentuate this effect, it is advisable to opt for models with minimalist profiles, or even without visible uprights. These "all-glass" configurations guarantee maximum transparency, promoting the diffusion of natural light throughout the room.

Lime-scale-resistant glass offers a significant advantage: simplified maintenance and long-lasting clarity. An 8 mm laminated glass wall, for example, combines impact resistance with visual lightness, ideal for preserving the harmony of a bath-shower area.

Several configurations can be adapted to suit the constraints and layout of the bathroom:

• Single fixed wall: perfect for transforming a classic bathtub into a functional shower.
• Pivoting wall: suitable for small spaces requiring flexible opening.
• Sliding walls: ideal for corner installations where clearance is limited.

The choice of transparency level is also decisive. Although tinted or screen-printed glass adds a decorative touch, it can reduce the perception of space. These finishes are more suited to spacious bathrooms.

Finally, the judicious use of mirrors in conjunction with glass walls considerably enhances the effect of grandeur. Placed opposite a source of natural light, a large mirror can almost double the perception of volume in the bath/shower area.

Choose continuous tiles for visual unity

Floor and wall coverings play a key role in the perception of space. Uniform materials, in particular, can visually transform a small bathroom. Using the same tiles for the floor and walls creates a continuous envelope that erases visual boundaries. Tone-on-tone grouting reinforces this effect, making transitions almost invisible.

The tile format also influences the feeling of space. Large rectangular tiles (60×120 cm), laid lengthwise, limit joint lines, visually lightening the room. In a combined tub-shower with walk-in shower, this floor-to-wall continuity multiplies the effect of depth.

Light shades, such as beiges or soft greys, reflect light better and bring an impression of volume and warmth. Imitation stoneware in natural tones enhances this luminous, soothing ambience.

Finally, the direction in which the tiles are laid has a strong influence on spatial perception: a diagonal or herringbone pattern adds depth, while a horizontal pattern visually enlarges the space. These installation details contribute fully to the illusion of a larger bathroom.

Finishes and styles for a harmonious look

To complete your bath/shower combo, finishes and style choices play a decisive role in the overall aesthetics of your bathroom. Every detail counts to create a harmonious whole that reflects your personality while optimizing the available space.

Technology fans will appreciate models equipped with a touch-sensitive control panel indicating temperature, or even integrated music to play a gentle melody during your bath.

Trendy colors for walls and fittings

In 2025, emerging bathroom colors focus on well-being and harmony. Green, in particular, is gaining in popularity for its soothing properties and ability to create a Zen atmosphere. For fittings, metallic finishes such as brushed black or brushed bronze add a sophisticated, contemporary touch. These shades go perfectly with natural materials such as wood or stone.

Affordable, accessible solutions

Despite the many advantages of bath and shower installations, the budget factor often remains a major concern. Fortunately, there are solutions to suit all budgets, without compromising on quality or functionality.

Inexpensive bath/shower combinations: where to find them

If you're looking for an affordable bath/shower combo, you have several options. DIY stores regularly offer standard models starting at €400, while complete bathtub-showers with enclosures can be found for between €500 and €1600, depending on type and materials.

For an economical renovation without major work, an alternative is simply to replace the faucets with a trendy color or add new accessories such as a mirror. This approach can achieve a refreshed bathroom for as little as a few hundred euros.

Do-it-yourself or call in a pro?

Do-it-yourself installation represents a significant saving on labor costs, generally ranging from €300 to €1,000 for the installation of a bathtub. However, this option is best suited to experienced do-it-yourselfers.
