Bathroom renovation step by step
Glazura, terracotta, hydraulics and water transfer – what influences the price of renovation?
Repairing the bathroom is one of the most demanding projects in the house. In addition to aesthetics, it is about functionality, resistance to moisture and compatibility with water and sewage installations. But before you start choosing tiles and fittings, get to know the repair stages and what really affects the price.
Step 1: Planning and design
Before you take the hammer in your hand, you need a plan.
It is important to specify:
- Bathroom arrangement: Do you want to change the place of the sink, toilet, washing machine, shower or bathtub?
- Style: Minimalist, classic, lofty?
- Budget: How much can you spend and what do you care most about?
Why does it affect the price?
The change in the system involves the need to rework the water and sewage system – this significantly increases the cost of labor and materials.
Step 2: Disassembly of old equipment
Remove:
- Old glaze and terracotta
- Toilets (washing machines, toilets, baths)
- Bathroom furniture
- Lighting and possibly suspended ceiling
Cost?
Dismantling can be cheaper if you do it yourself. A professional company will add man-hours and export debris (sometimes expensive in large cities).
Step 3: Hydraulics and electricians
This is a key step – includes:
- Exchange of pipes (if old or in bad condition)
- Transfer of water points (e.g. shift of shower)
- Power supply to new points (e.g. socket with washing machine)
- Installation of valves, drains, siphons
Why does it cost?
This is the work of specialists, requiring precision and compliance with building regulations. Each additional point is more work and materials (e.g. elbows, tubes, connectors). The exchange of verticals or the assembly of the plaster racks can raise the price by several thousand zlotys.
Step 4: Preparation of walls and floors
Before the new glaze appears:
- Walls need to be leveled, grounded
- Sometimes hydro insulation is necessary (especially in wet zones – shower, bath)
- On the floor, self-leveling tinctures are used
Cost?
Depends on the condition of the walls and floors. The more curves, the more you pay to level and prepare the ground. Hydroisolate is an extra cost, but a necessary cost.
Step 5: Installation of glaze and terracotta
This is the most time-consuming phase:
- Tiles need to be cut, fold, level
- Fugination and impregnation
- Decorative elements such as mosaics or slats often arrive
What affects the price?
- Type of tiles (small, mosaics, large format are more expensive in arrangement)
- Number of cuts and details (e.g. tiles around the linear outflow)
- Glazurnik experience – better professionals are more expensive, but quality of work compensates for costs
Step 6: Installation of sanitary facilities and furniture
When the tiles are dry:
- The toilet shall be fitted (mountain or compact)
- Connects sink and batteries
- Sets a shower or bath
- Bathroom furniture, mirrors, lighting are inserted
Price?
A lot depends on the equipment you choose. A toilet with bidet or freestanding bath can cost several thousand zlotys. The assembly itself – if it needs accurate fit – is also more expensive.
Step 7: Finishing and cleaning
It remains:
- Siliconation
- Sealing tests
- Final amendments and thorough cleaning
What else affects the price of the bathroom renovation?
| Factor | How does it affect the price? |
|---|---|
| Bathroom area | More meters = more materials and work hours |
| Material Standard | Plates for 30 zł/m2 and for 300 zł/m2 is a gap |
| Modification of the hydraulic system | Each shift increases the cost by up to PLN 500–2000 |
| Technical States | If you discover damaged pipes, moisture, fungus – cost increases |
| Availability of professionals | In large cities labour prices are much higher |
Summary
Bathroom renovation is a complex process that is worth planning well. The key to success is not only aesthetics, but also a thoughtful installation, solid construction and moisture resistant materials. Remember – the most cost changes that are not visible to the naked eye: moving pipes, verticals or electrical points. Therefore, it is worth to have a detailed estimate and design before the renovation starts – to avoid surprises.
