A full renovation of a 50 sq.m. apartment is one of the most common investments, as this size is ideal for singles, couples, and for short- or long-term rental purposes. A complete renovation of a 50 sq.m. home costs approximately €35,000–€38,000. However, the final amount may vary significantly depending on the extent of the changes you wish to make, the quality of materials selected, and whether specialized technical solutions are required.
Let’s take a detailed look at how prices are shaped in 2026 and exactly where your money goes.
Demolition – Debris Removal
During the renovation, doors, window frames, tiles, sanitary ware, old wardrobes, etc., will be removed. These materials are collected in waste containers. Three containers are required, with each container costing 150€. Labor costs are approximately 1,200€.
Total demolition cost (approx.): 1,650€ (1,200€ + 3 × 150€)
New Masonry or Drywall Installations
If drywall needs to be installed or new walls constructed (e.g., to divide spaces), this entails additional cost. For a 50 sq.m. apartment, the average cost is approximately 750€.
Plumbing
Plumbing renovation is one of the most important aspects of a renovation and includes new piping, radiator replacement, and installation of sanitary fixtures. For a 50 sq.m. home, plumbing labor costs approximately 2,200€.
We add 4 new radiators at 200€ each, including installation (800€), and a solar water heater costing 1,000€.
Total plumbing cost (approx.): 4.000€ (2.200€ + 800€ + 1.000€)
Electrical Installations
Electrical systems have evolved significantly compared to the past. A renovation requires new electrical installations, including multiple power outlets, a UTP data network, and alarm wiring. Fiber optic installation and various smart home systems could also be added; however, these would significantly increase the cost. Therefore, we are considering a standard installation with a new electrical panel, data network in all rooms, and alarm wiring.
The cost for 50 sq.m. is approximately 3,500€, plus an additional 450€ for branded switches and sockets.
Total electrical cost (approx.): 3,950€.
If the apartment has 2 bedrooms, the price rises to approximately 4,200€.
Plastering – Repairs
Plumbing and electrical work will have caused damage in various areas of the house. These must be repaired with plastering and finishing work.
For 50 sq.m., plastering costs approximately 1,000€.
External Window Frames
The next stage is replacing the external window frames. We choose thermally insulated frames to reduce heating and cooling losses. In a 50 sq.m. apartment, there are typically 2 balcony doors and 2 windows. The cost also includes shutters and insect screens.
Average cost: 4.200€ (approx.)
Wall and Ceiling Skimming
Before painting, walls and ceilings must be skim-coated with a thin layer of putty to create a smooth surface. If you choose to apply putty only to selected areas to save money, walls may not appear perfectly smooth and patch marks could remain visible.
For 50 sq.m., this cost is approximately 1.900€.
Flooring
At this stage, new flooring is installed throughout the home. Tiles are typically chosen for the kitchen and living room, while wooden flooring is preferred for the bedroom. Tiles cost 20€ per sq.m., and installation (including necessary materials) costs 25€ per sq.m.
Total flooring cost: 1,450€ (approx.). If there is a second bedroom, the cost rises to approximately 1,650€.
Bathroom – Sanitary Ware
Next is the bathroom renovation. The total cost for a full bathroom renovation, including new sanitary ware, tiles, piping, and labor, amounts to approximately 3,000€.
Kitchen
Kitchen renovation is one of the most important stages, as it is a space where we spend much of our day. The focus is on combining aesthetics and functionality. A full renovation includes new cabinets, countertop, tiles, and plumbing installation.
Cost: 3,300€ (approx.)
Wardrobes
In a 50 sq.m. apartment, one bedroom wardrobe is usually sufficient. The cost for a quality wardrobe is approximately 1,400€. Besides functionality, it significantly enhances the aesthetics of the space.
If there is a second bedroom, a second wardrobe is required, raising the cost to 2,600€.
Interior Doors & Security Door
For a 50 sq.m. residence, we estimate 2 interior doors (e.g., bathroom and bedroom) and 1 security door. The 2 interior doors cost 350€ each (700€ total), while the security door costs approximately 700€.
If there is a second bedroom, three interior doors are required.
Total cost: 1,400€ (approx.) for one bedroom and 1,750€ (approx.) for two bedrooms
Air Conditioning
A complete renovation would not be complete without air conditioning. A 40 sq.m. area is typically covered comfortably by one air conditioning unit costing approximately 600€ (including installation).
If there are separate spaces, a second unit may be needed, raising the price to 1,200€.
Painting
After completing all necessary work, it’s time to calculate the painting cost. The price may vary depending on the chosen colors. Below is an indicative estimate:
Painting a 50 sq.m. residence costs approximately 1,000€. If there is a second bedroom, the cost rises to approximately 1,200€.
Miscellaneous Works
Some renovation tasks do not fall into the above categories, such as exterior painting, railing maintenance, transport of materials to the site, protective packaging of items, cleaning during the project, and various minor materials.
Typical cost: 650€ (approx.)
Permits – Social Insurance (IKA) – Debris Disposal
At Mecha, beyond the standard works, we also assist with work permits and workers’ insurance costs. This amount also includes certified debris disposal.
Typical cost: 1,250€ (approx.)
Project Design – Construction Company Fee
Architectural design, 3D visualization, material selection, and full project management and supervision by the construction company amount to approximately 3,500€ for a 50 sq.m. residence. This fee also includes a workmanship quality guarantee.
