In a studio flat measuring just 15 square metres in Paris’s 13th arrondissement, renovating the bathroom was the top priority. Space was exceptionally limited, while the existing fittings were outdated and impractical. An interior design team completely reworked this tiny wet room, demonstrating just how much comfort can be created in the smallest of spaces.
From problem room to relaxing retreat
Before the renovation, the compact wet room was more an emergency solution than a proper bathroom. It felt dark, cramped and makeshift. Its function and appearance reflected that: rather like a storage cupboard with a water connection than a place where anyone would want to begin the day.
The central issue was that the shower and toilet were virtually on top of each other. To shower, the occupant had to lower the toilet seat and turn on the shower head directly above the toilet. There was only a miniature separate basin, and storage was effectively non-existent.
“A purely functional room with no atmosphere whatsoever became a considered, modern retreat that genuinely welcomes its resident.”
To transform the space, the design practice focused on two key measures: a completely new layout and carefully selected compact sanitary fittings.
Smart bathroom planning: every centimetre matters
In very small bathrooms, the position of the toilet, basin and shower determines whether the room works well or becomes frustrating. This was precisely where the team began.
Moving the basin into the corner
Rather than placing the vanity unit centrally, it was moved into a corner of the room. This straightforward adjustment freed up valuable centimetres that had previously gone unused. The slimmer unit then left sufficient room for a wall-hung toilet with a concealed cistern.
- Basin positioned in the corner to open up circulation space
- Wall-hung toilet to keep more of the floor visible
- Slim shower screen tailored exactly to the room
- Compact heated towel rail providing both warmth and drying space
The sanitary elements come from ranges designed specifically for small floor plans: a narrower shower screen, a slim basin unit and a space-saving heated towel rail. The selection shows how much the market now offers for mini bathrooms, provided you know what to look for.
A defined shower area instead of wet room chaos
The most striking change is that the shower and toilet no longer form one combined area. The new shower has a clear separation using glass and profiles, so the user no longer stands directly on the tiles in front of the toilet. This not only feels more hygienic, but is also more relaxing psychologically.
Thanks to the careful positioning of the shower area, the space in front of the basin remains surprisingly generous, even though the floor plan has barely increased. The redesigned room can be used intuitively, without contortions or acrobatic manoeuvres.
Design concept: soft, light and finished with black accents
Once the basic layout had been resolved, attention turned to appearance. Before the refurbishment, bare walls and an almost austere feel dominated the room. It was somewhere one would want to leave as quickly as possible.
The new design scheme relies on soft forms, light shades and a clean visual line. Accessories and ceramics share a calm, rounded language: there is no harsh, angular clinical look, but instead a welcoming, homely feel.
“Rounded forms remove the severity from the mini bathroom, while black metal adds character.”
At the same time, a bold contrast is introduced through black metal. It appears throughout the room and visually ties the scheme together:
- Mirror frame
- Taps at the basin and in the shower
- Profiles and handles on the shower screen
This recurring feature adds structure and a hint of industrial character to the bathroom. The black finish echoes design details in the studio’s main living area, where industrial touches are also used. As a result, the entire flat feels cohesively designed.
Light, colours and materials: leaving the dark room behind
The shift “from dark room to the spotlight” is achieved above all through the revised lighting scheme. Light wall surfaces reflect the available daylight more effectively, while additional lighting at the mirror and on the ceiling prevents shadowy areas.
The colour palette has deliberately been kept restrained: light, neutral shades are used for the walls and tiles, with warmer tones introduced through wood or wood-effect surfaces. This makes the room appear larger and calmer. Black metal details provide focused accents without becoming visually overwhelming.
| Before | Now |
|---|---|
| Bare walls, hardly any colour | Light surfaces, clearly defined accents |
| Dark, with limited lighting | Several light sources, a welcoming atmosphere |
| Inconsistent appearance | A cohesive design concept |
Functionality you can feel, not just see
Looking good is one thing; working in everyday life is another. The new layout therefore gives considerable thought to practical routines: where towels are placed, where shower gel is kept, and how the light switch can be reached without having to stretch across the room.
The heated towel rail is mounted so that towels remain within easy reach while drying at the same time. The basin unit provides enclosed storage for toiletries and cleaning products. Open surfaces have been reduced to keep the room tidy and minimise dust.
“The smaller the bathroom, the more severely planning mistakes stand out – and the more worthwhile every good decision becomes.”
What others can learn from this project
Many urban homes in Germany face similar layouts: tiny bathrooms, some still dating from the 1970s or 1980s, with little appeal and poor spatial organisation. This Paris example offers practical ideas that can be applied elsewhere.
Three key lessons for mini bathrooms
- Put function first: Plan routes and daily routines before choosing tiles and colours.
- Think in corners: Corner solutions for the basin or shower often recover crucial centimetres.
- Create a common thread: A recurring material or colour links the bathroom with the rest of the home.
Choosing suitable products is equally important. Many DIY retailers and manufacturers now offer ranges for “Small Spaces”, including slim basins, shortened toilets and space-saving shower trays. Anyone who specifically looks for these ranges can avoid making the bathroom feel like a miniature version of a large one, with everything simply squeezed inside.
When professional bathroom planning is worthwhile
Professional planning often makes the decisive difference, especially in very small rooms. It is not simply about attractive sketches, but precise work down to the millimetre: will the door still open properly? Can the shower control be used without knocking an elbow? How far may the toilet project into the room before it obstructs the entrance?
Design practices and specialist bathroom studios work with exact measurements, often including 3D models. This makes it possible to see in advance whether the concept is coherent. Doing this thinking before construction begins avoids costly corrections later.
Benefits beyond the bathroom
A well-planned mini bathroom improves not only everyday comfort but also the value of a small home. In studios and micro-apartments in particular, tenants and buyers are increasingly attentive to the quality of wet rooms. A modern, functional sanitary space can become a genuine selling point.
The Paris example illustrates just how much potential can lie in what seems to be a problem area. With precise planning, consistent design and suitable products, a neglected room becomes a small gem – and going to the bathroom suddenly becomes something to look forward to rather than postpone.
