What aspects can increase the bathroom renovation budget? with Reformia
The average cost of renovating a bathroom of approximately 5.40 m² is around 3,500 €, that is, around 650 €/m². The cost will depend on the type of renovation, the materials used and the quality of the finishes.
1. Lack of planning
Any improvisation during construction work can cause the budget to skyrocket. In the case of bathrooms, examples can be very different: it can be a last-minute distribution change that involves modifying the installations, or it can be the choice of materials that were not originally planned.
2. Quality of materials
There are countless materials of very different qualities, both in flooring and surfaces as well as fixtures or furniture. Since the bathroom is a humid space and subject to intensive use, it is advisable not to compromise on this aspect, although when calculating how much the work costs, the price will increase.
3. Custom-made furniture
Custom-made furniture has great advantages, such as adapting to the available space in the bathroom (you must keep in mind the minimum bathroom dimensions) and also to personal tastes. However, it has the disadvantage that this type of furniture can be much more expensive than mass-produced models.
The average cost of renovating a bathroom of approximately 5.40 m² is around 3,500 €, that is, around 650 €/m². The cost will depend on the type of renovation, the materials used and the quality of the finishes.

Steps to plan a bathroom renovation
The average cost of renovating a bathroom of approximately 5.40 m² is around 3,500 €, that is, around 650 €/m². The cost will depend on the type of renovation, the materials used and the quality of the finishes.
1. Planning the renovation
It is essential to decide in advance what the bathroom elements will be, the distribution of fixtures and furniture in the renovation. You also need to consider whether it will be necessary to improve the ventilation system or take any other measure to prevent moisture.
You can simplify the routes of the supply and drain pipes to make the renovation cheaper: for example, relocating a fixture to place it as close as possible to the original drain can save money and possible problems if there were a breakdown.
In addition, a pre-established order should be followed in the renovation to ensure maximum efficiency: after demolition and debris removal of the bathroom, structural changes should be made to the space, such as removing walls, moving a door or creating an opening for a new window. Next, the upgrade of installations, pipes and everything related to utilities should be carried out. Then the surfaces of floors, walls and ceiling should be changed; and finally, the installation of fixtures, furniture and finishes.
2. Bathroom budget forecast
As a guide, the budget for a comprehensive bathroom renovation usually follows the following distribution:
It is important to clearly establish the cost of each item and specify it clearly in the budget before starting the renovation, in addition to setting aside some budget for possible unforeseen circumstances.
3. Management of licenses and permits
Licenses for home renovations are divided between minor and major work permits:
It is advisable to install a shut-off valve on each fixture, so if there is a breakdown or leak, the general supply does not have to be cut off. In new construction homes it is mandatory; otherwise you can take advantage of the water installation renovation to incorporate the valve.
4. During the execution of the renovation
The comprehensive renovation of a 4 m² bathroom has an average duration of one week, although in some cases it can take longer. Depending on the type of material, more or less specialized labor may be needed.
Factors such as maximizing natural light, heating and ventilation of the bathroom should be considered. If there is no natural ventilation system, it will be essential to install a bathroom exhaust fan to help reduce humidity and eliminate odors.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Bathroom size and layout
Smaller bathrooms (3-4 m²) have a higher cost per square meter, while larger bathrooms (6-8 m²) spread fixed expenses. The shape and layout also affect the complexity of plumbing and drainage installation.
Quality and type of materials
Price varies significantly depending on whether you choose basic, mid-range, or premium materials. Imported ceramics, branded fixtures, designer sanitaryware, or special finishes can increase the budget by 30% to 100%.
Scope of the renovation
A complete renovation with plumbing changes, electrical work, tiling, and new sanitaryware is more expensive than a surface-level refresh of finishes only. Renovations requiring structural changes or significant plumbing work can double the base budget.
Previous condition and additional work
If the bathroom requires moisture damage repairs, old pipe replacement, or structural fixes, costs increase considerably. The need for special waterproofing also affects the final price.
Breakdown of bathroom renovation budget items
The average cost of renovating a bathroom of approximately 5.40 m² is around 3,500 €, that is, around 650 €/m². The cost will depend on the type of renovation, the materials used and the quality of the finishes.
The average cost of a bathroom renovation involves different aspects. The first of these is the size of the room.

The budget for a comprehensive bathroom renovation project should include different items. In the case of a medium-sized bathroom (6 m²), this would be an example of a bathroom renovation budget:
TOTAL: 6,000 €, using quality materials and including installation upgrades, labor and furniture.
- Labor: each professional or company applies their own rates, but on average, this item can represent between 10% and 20% of the final budget.
- Masonry work: its price starts at 25 €/m² for surface work. However, depending on the model chosen, that cost can double.
- Debris removal: removing fixtures, screen and furniture; demolishing tiles, floors and false ceilings; debris removal and disposal to landfill can cost around 600 €.
- Fixtures: the cost of all bathroom fixtures, including shower or bathtub with screen, toilet, sink, bidet and taps would cost around 1,500 €. Installation will cost at least another 300 €.
Partial bathroom renovation
This is a type of renovation where only some elements of the room are changed. The reasons can be very different: very tight budget, inability to do without the bathroom for a long time if the work extends, renovation of only deteriorated elements, etc.
You can renovate the bathroom for 1,000 euros. However, the possibilities for a partial bathroom renovation are many, although some are more common:
- Technical Building Code (https://www.codigotecnico.org/)
- REBT (Low Voltage Electrotechnical Regulations). Royal Decree 842/2002, of August 2, which approves the electrotechnical regulations for low voltage: https://www.boe.es/buscar/act.php?id=BOE-A-2002-18099
