Bathroom Renovation - A bathroom renovation involves the comprehensive overhaul of an existing bathroom, from the water lines and drains to the tiles and subfloor, as well as the fixtures and fittings. Unlike a simple refurbishment (painting, replacing fixtures), a complete renovation involves stripping the bathroom down to the structural framework and rebuilding it from scratch.
A complete bathroom renovation begins with careful planning. First, the existing conditions are assessed: How do the water and sewer lines run? Is the existing electrical connection sufficient for modern requirements such as electric floor heating or an illuminated mirror cabinet? Do load-bearing walls need to be taken into account?
The next step is demolition. Old tiles, fixtures, and often the subfloor are removed. Especially in homes built between the 1960s and 1980s, we often encounter outdated lead or copper pipes that must be replaced. The rough-in installation of water, wastewater, and electrical systems forms the foundation of the renovation.
Next, the new subfloor is installed, with integrated underfloor heating if applicable. After the drying period, professional waterproofing in accordance with DIN 18534 is performed; this is essential in wet areas, and failure to do so may result in the loss of insurance coverage in the event of damage. Only then are tiles laid and the new fixtures installed.
| Features | Bathroom Size | Estimated Total Cost |
|---|---|---|
| Standard (simple tiles, brand-name tub) | 5-6 m² | €10,000-15,000 |
| Mid-range (floor-level shower, porcelain tile) | 5-6 m² | €15,000-22,000 |
| Upscale (designer fixtures, natural stone, bathtub) | 7-9 m² | €22,000-35,000 |
| Luxury (steam shower, smart home, freestanding bathtub) | 8-12 m² | €35,000-€60,000 |
Additional costs arise if pipes need to be laid, load-bearing walls need to be opened, or if hidden mold or moisture damage is discovered. We recommend always budgeting a contingency of 10-20% of the total cost for unforeseen work in older buildings.
The actual construction time is usually three to six weeks. Added to this are drying times for the screed and waterproofing, which-depending on the heating system used and the season-can take four to six weeks. Overall, owners should expect eight to twelve weeks from demolition to completion.
Typical Schedule:
| Week | Work |
|---|---|
| 1 | Demolition, waste disposal, rough plumbing installation |
| 2 | Electrical installation, pouring screed |
| 3-6 | Screed drying time (accelerated by heating) |
| 7 | Waterproofing, tile preparation |
| 8-9 | Tile installation |
| 10 | Installation of sanitary fixtures and fittings |
| 11 | Final assembly, silicone application, painting |
| 12 | Final inspection, remaining work |
Effective coordination of the trades by an experienced construction manager can significantly shorten the overall duration.
The walk-in shower has become the standard-it is not only visually appealing and easy to maintain but also offers the advantage of accessibility. Those who implement further accessibility measures during the renovation (sufficient movement space of at least 120 × 120 cm, appropriate wall clearance, and grab bars) can apply for funding through KfW:
For landlords: Modernization costs may be passed on to the rent at a rate of 8% per annum pursuant to Section 559 of the German Civil Code (BGB), provided that the living quality is sustainably improved.
A modern, renovated bathroom significantly increases a property’s market value. Buyers pay particular attention to the condition of the bathroom and kitchen during viewings. An outdated bathroom from the 1980s can reduce the selling price by 10,000 to 20,000 euros, while a contemporary bathroom renovation increases the value by a comparable amount. The ratio of investment to value appreciation is therefore often exceptionally favorable for bathroom renovations.
The Nuremberg metropolitan area has a large stock of apartments from the post-war period and the economic miracle years-many bathrooms have not been thoroughly renovated in decades. Anyone planning a bathroom renovation in Nuremberg, Fürth, or Erlangen should contact contractors early on, as demand for plumbing services in the region is high. Waiting times of three to six months are not uncommon.
We recommend obtaining at least three quotes and ensuring a detailed scope of work to minimize additional charges during the construction phase. Choose a contractor who coordinates all trades (plumbing, electrical, tiling)-or assign the coordination to a project manager. This saves time and avoids gaps in liability.
The actual construction time is usually three to six weeks. Add to that drying times for the subfloor and waterproofing of four to six weeks. Overall, homeowners should expect eight to twelve weeks from demolition to completion. Effective coordination of the trades by an experienced construction manager can significantly shorten the total duration. We recommend planning an alternative solution early on if the renovation project involves the only bathroom in the home-without an alternative bathroom, a renovation is hardly practical in busy households.
Do-it-yourself work is generally possible and can reduce costs by 20 to 30 percent. Demolition and painting are well-suited for experienced DIYers; laying vinyl flooring in adjacent rooms is also often possible as a DIY project. However, we strongly advise against doing your own plumbing, electrical work, or waterproofing: mistakes in these areas lead to water damage, mold growth, or safety risks. In addition, improper waterproofing often voids insurance coverage in the event of damage. Materials that the homeowner purchases themselves and has a contractor install can reduce costs-clarify this with the contractor in advance.
In most cases, yes. A modern bathroom is one of the strongest selling points for residential properties. We regularly observe in the Nuremberg market that properties with renovated bathrooms sell faster and command higher prices. Especially for existing apartments in sought-after neighborhoods like Gostenhof, Maxfeld, or the Südstadt, a new bathroom makes the decisive difference in the purchase decision. A full renovation before selling is especially worthwhile if the condition of the bathroom significantly limits the pool of potential buyers-for example, in the case of older bathrooms with a tub but no shower and outdated tiles, which present a high emotional barrier for many buyers. Let us advise you on which measures will have the greatest impact in your specific case.
