Bathroom renovation – costs, options & planning
A new bathroom is one of the most valuable investments in a property – not only visually, but also in terms of living comfort, energy efficiency and resale value. Many houses and apartments in Switzerland date from the 1960s to 1990s and are now due for their first major renovation. But how much does a bathroom renovation really cost? Which factors influence the price? And what is the difference between a basic, average and luxury bathroom renovation?
In this guide, you’ll get a clear overview of typical costs, all major pricing factors, realistic examples and practical tips to help you plan your new bathroom not only beautifully, but also efficiently and sensibly.
How much does a bathroom renovation cost?
The cost of a bathroom renovation depends heavily on room size, material selection, the condition of existing plumbing and the desired quality level. For quick orientation, it helps to look at typical bathroom categories: basic, average and premium. The following reference values include the most important components such as sanitary fixtures, tiling work, standard fittings, built-in furniture and installation.
Basic bathroom
A basic bathroom is functional and solidly equipped. It includes standard sanitary ceramics such as a shower or bathtub, single washbasin, toilet, simple fittings and ceramic standard tiles in wet areas only. The layout remains simple, and special materials or additional comfort features are avoided.
Costs: approx. CHF 1,000–1,500 per m²
Example: 12 m² ≈ CHF 12,000–18,000
Average bathroom
An average bathroom already offers noticeably more comfort. Typical features include a walk-in shower, double washbasin, higher-quality fittings, larger mirror cabinets and natural stone or large-format tiles on floors and walls. Additional details such as rain showers or heated towel rails are often included.
Costs: approx. CHF 1,200–1,700 per m²
Example: 12 m² ≈ CHF 14,400–20,400
Premium / luxury bathroom
Luxury bathrooms focus on exclusive materials, seamless wall surfaces, high-end fittings, wellness elements, freestanding bathtubs or steam showers, as well as custom-made furniture. Technical extras such as ambient lighting, smart home controls or premium natural stone finishes are common.
Costs: approx. CHF 2,000–3,000 per m²
Example: 12 m² ≈ CHF 24,000–36,000
Price range per m² (quick reference)
For a quick cost estimate – regardless of bathroom size – the following guideline values apply:
● Basic: CHF 1,000–1,500 per m²
● Average: CHF 1,200–1,700 per m²
● Premium / luxury: CHF 2,000–3,000 per m²
These figures serve as realistic benchmarks and help you define your budget more accurately.

The most important cost factors in a bathroom renovation
Room size & layout
The larger the bathroom, the more material, labor time and installation work is required. Awkward or angled room layouts increase effort due to additional cutting, custom solutions and more detailed planning.
Condition of existing plumbing (water, drainage, electricity)
If pipes are outdated, damaged or no longer compliant, they must be replaced or rerouted. This increases complexity and often requires additional work behind walls, under floors or on electrical systems.
Choice of sanitary ceramics & fittings
Whether standard products or designer elements are installed has a major impact on cost. Premium fittings, freestanding bathtubs or walk-in showers often require more precise installation, special substructures or custom adaptations.
Wall & floor materials (tiles, natural stone, seamless surfaces)
Different materials require different installation techniques. Large-format tiles, natural stone or seamless surfaces demand more expertise, careful preparation and longer installation times than standard tiles.
Floor plan changes & relocation of installations
If sanitary fixtures are moved to new positions – for example replacing a bathtub with a shower or relocating a toilet – pipes, drains and connections must be adjusted. This significantly increases planning and installation costs.
Accessibility & special solutions
Age-appropriate adaptations such as walk-in showers, non-slip floors, grab bars or wheelchair-accessible sinks require tailored planning and often special components, increasing coordination and installation effort.
Regional differences & availability of tradespeople
In metropolitan areas, labor costs are generally higher. At the same time, limited availability of qualified tradespeople can delay projects and increase overall coordination costs.
Extras and comfort options in a bathroom renovation
In a bathroom renovation, extras in particular can significantly increase the overall cost. Many of these comfort options not only enhance the design, but also improve everyday usability and the long-term value of the bathroom. Below is a concise overview of the most popular additional features, including realistic price ranges.
Freestanding bathtub
Freestanding bathtubs look luxurious and are a real visual highlight. However, installation requires more space and often additional plumbing adjustments.
Cost: approx. CHF 3,000–5,000 (including installation)
Whirlpool / steam shower
Whirlpool bathtubs and steam showers greatly increase the wellness factor. They usually require stronger power connections, additional plumbing and extra sealing.
Cost: Whirlpool CHF 3,000–7,000 · Steam shower CHF 3,000–5,000
Shower toilet (dusch WC)
Modern shower toilets combine comfort, hygiene and technology (spray functions, drying, heated seat). Installation usually requires a power connection.
Cost: approx. CHF 2,000–3,000
Natural stone and seamless surfaces
High-quality natural stone slabs or seamless wall and floor finishes are easy to maintain and visually sophisticated. However, they require precise workmanship and special materials.
Cost: depending on surface area, approx. CHF 3,000–5,000
Heated towel rail
A small upgrade with a big comfort benefit: warm towels and additional heat in the bathroom.
Cost: approx. CHF 700–1,200
Ambient lighting
LED light strips in mirrors, ceilings or niches create atmosphere. Smart home control is also possible.
Cost: approx. CHF 1,000–3,000
Custom-made cabinets and bathroom furniture
Individually made furniture optimizes storage space and fits perfectly into the floor plan. Ideal for small or angled bathrooms.
Cost: approx. CHF 2,000–5,000
Saving tips for your bathroom renovation
Choose materials wisely
The biggest cost drivers in a bathroom are surfaces and sanitary ceramics. If you opt for high-quality porcelain tiles instead of natural stone, or choose mid-range fittings instead of designer brands, you can often save several thousand francs without visible compromises.
Reduce custom solutions
The fewer special solutions, the more affordable the renovation. Standard sizes for showers, furniture or glass partitions significantly reduce planning and installation effort. Custom-made solutions only make sense if the layout strictly requires them.
Compare quotes
Prices between construction companies and sanitary installers can vary considerably. Obtain at least three quotes and carefully check which services are included (demolition, plumbing work, waterproofing, tiling). Price differences of 15–30% are common.
Do some work yourself
Not everything has to be done by professionals. Removing old furniture, clearing the room, minor preparatory work or even painting can be done yourself. This reduces labor hours, which are often the most expensive part.
Standard sizes instead of custom dimensions
Vanity units, bathroom furniture or glass walls in standard sizes are significantly cheaper than custom-made versions. If the room geometry allows it, standard modules should be preferred.
Good planning saves thousands of francs
A clearly defined concept prevents expensive changes during construction. Decide on colors, materials, sanitary fixtures and positions before work begins. Any later change increases labor effort and total costs.
A bathroom renovation increases comfort and property value
A bathroom renovation is one of the most effective modernization measures in Swiss apartments and houses. Whether a simple refresh or a luxury full renovation, the right planning, realistic budgeting and clear priorities determine whether the project runs smoothly, on time and cost-efficiently.
Those who compare quotes early, choose standard solutions and understand the key cost factors can save several thousand francs without sacrificing comfort or aesthetics. With experienced professionals, you get a bathroom that is stylish, durable and perfectly tailored to your everyday needs.
