Bathroom Renovation in Paris: Budget, Condominium Regulations and Financial Assistance (Controlling New Housing Costs)

The bathroom has become the favorite room of the French, but in Paris, it is often the smallest! Renovating a 3m² or 4m² bathroom in an old building is an exciting technical and aesthetic challenge. It is an opportunity to value your property and to gain invaluable daily comfort.
But be careful: touching the plumbing in a multi-family building cannot be improvised. Water damage, evacuation problems, lack of pressure... the pitfalls are numerous. Chez Tubulure network, we are specialized in Parisian bathroom renovation. Here is our complete guide to the success of your project.
The Specificities of the Parisian Bathroom
Forget Pinterest photos of huge 15m² bathrooms. In Paris, the reality is different and requires ingenuity.
Optimizing Space (Le Tétris)
Every centimeter counts. We work with “space-saving” equipment:
- Compact suspended toilets: They free up the floor and make cleaning easier.
- Low depth vanity units: To move around easily.
- Custom showers: To use the quirky corners.
- Sliding or pocket doors: So as not to lose 1m² when the door is opened.
Evacuation Management (La Pente)
This is the crucial technical point. To install a shower (especially an Italian shower at ground level), water must be drained. However, in older buildings, the evacuation column is sometimes far away or raised.
- The Tubulure Network solution: If gravity is not enough, we can install silent lift pumps or create a slight designer platform to hide the pipes while ensuring a correct slope of 1 to 2 cm/m.
Budget: How much does a renovation cost in Paris?
The price per m² for a bathroom renovation is higher than for a bedroom, because it involves several trades (plumbing, tiling, electricity, painting). Count on average between €3,000 and €8,000 including VAT for a complete renovation of a small bathroom (3-5m²), supplies and labor included.
What makes the price vary:
- The condition of the existing plumbing: Do you have to redo the entire copper supply or just change the elements?
- The tiling: The installation of mosaics or XXL tiles requires more time than standard tiles.
- The equipment: A built-in thermostatic faucet costs more than a conventional mixer.
We provide a detailed quote item by post. No vague global package. You know how much it costs to remove it, how much it costs to remove the faucets, etc.
Italian shower in an apartment: dream or nightmare?
Everyone wants an Italian shower (without steps). In Paris, upstairs, it is technically complex because you have to embed the siphon into the ground. However, you cannot dig into the slab of the neighbor below!
Our solutions:
- The extra-flat tray: It's the best compromise. It is only 3 or 4 cm high, can be placed on the floor, and perfectly imitates the “Italian” effect without the risks of infiltration of a tiled shower.
- Watertightness under tiles (SPEC): If we tile the shower, we must apply a sealing mat or resin under the tiles. It's your guarantee against water damage (and it's mandatory for insurance companies).
