Wetroom installation in Prague typically costs between 80,000 and 250,000 Kč, depending on the room size, waterproofing method, drainage system, and finish materials. A wetroom — a fully waterproofed, open-plan shower space with no tray or enclosure — is increasingly popular in Prague apartments and houses, but getting it right demands specialist skills that go well beyond a standard bathroom refit.
This guide covers realistic 2026 pricing for wetroom projects in Prague, what the job actually involves, how to find a qualified installer, and the mistakes expats commonly make when commissioning this kind of work in Czech Republic.
What Does Wetroom Installation Cost in Prague in 2026?
Wetroom costs vary significantly based on scope. Here are typical price ranges you can expect from Prague tradespeople in 2026:
- Small wetroom (up to 4 m²): 80,000–140,000 Kč
- Medium wetroom (4–7 m²): 130,000–200,000 Kč
- Large or luxury wetroom (7+ m²): 180,000–250,000+ Kč
- Converting an existing bathroom to a wetroom: 100,000–220,000 Kč (includes demolition of old fixtures)
These ranges include labour, tanking (waterproofing), drainage installation, tiling, and basic fixtures. They do not include high-end designer tiles, heated towel rails, or underfloor heating — each of which adds to the final bill.
What Drives the Price Up?
Several factors can push your wetroom project toward the higher end of the range:
- Waterproofing complexity: Older Prague buildings (especially pre-war panelák or činžovní domy) often have uneven floors and outdated plumbing. Creating a proper fall toward the drain on an uneven subfloor requires more screed work and time.
- Linear drain vs. point drain: A linear (channel) drain along one wall looks sleek but costs 3,000–12,000 Kč more than a standard point drain, plus extra labour to set the gradient correctly.
- Tile choice: Large-format porcelain tiles (60×60 cm or bigger) are popular for wetrooms but harder to lay on sloped floors, increasing tiling labour by 20–30%. Natural stone requires sealing and special adhesives.
- Underfloor heating: Electric mat systems for a wetroom floor typically add 15,000–30,000 Kč including installation.
- Glass screens: A partial glass panel (walk-in style) costs 8,000–20,000 Kč depending on size and fittings.
Labour Costs Breakdown
In Prague, wetroom specialists typically charge in one of two ways:
- Hourly rate: 450–700 Kč/hour for a skilled tiler or plumber
- Fixed project price: More common for wetroom jobs, where the installer quotes the entire scope after a site visit
A fixed price is generally better for both sides on a wetroom project because the waterproofing and gradient work is hard to estimate by the hour. Always get the quote in writing — ideally as part of a smlouva o dílo (work contract), which is standard practice in Czech Republic.
What Does Wetroom Installation Actually Involve?
A wetroom is not just a bathroom without a shower tray. The entire room becomes a wet zone, which means every surface must be fully waterproofed (tanked). Here is the typical installation process:
- Strip-out: Remove existing bathroom fixtures, tiles, and sometimes the screed down to the substrate.
- Plumbing rough-in: Install or relocate drain pipework. The drain position determines the floor gradient, so this step is critical.
- Floor gradient (spádování): Apply a screed layer that slopes evenly toward the drain — typically at a 1–2% gradient. This is the most technically demanding part of the job.
- Tanking / waterproofing (hydroizolace): Apply a liquid membrane or sheet membrane to the entire floor and walls (at least to splash height, ideally full height). Joints, corners, and drain connections get reinforced with tape or collars.
- Tiling: Lay floor and wall tiles using flexible, waterproof adhesive. Grout with epoxy or polymer-modified grout for water resistance.
- Fixture installation: Mount the shower valve, showerhead, glass screen (if any), and accessories.
- Silicone sealing and finishing: Apply sanitary silicone at all joints and transitions.
The entire process typically takes 5–10 working days for a standard-sized wetroom, depending on drying times for screed and waterproofing layers.
Wetrooms in Prague Apartments: What Expats Need to Know
If you live in a Prague apartment building (bytový dům), there are specific considerations that don't apply to houses:
SVJ Approval
Most apartment buildings in Czech Republic are managed by an SVJ (společenství vlastníků jednotek — owners' association). If your wetroom installation involves changes to shared plumbing risers, floor structure, or waterproofing that could affect neighbours below, you may need SVJ approval before starting work. Check your building's stanovy (bylaws) or ask your SVJ committee.
Noise and Access Restrictions
Many Prague SVJs restrict noisy construction work to weekday daytime hours (typically 8:00–18:00). Demolition and drilling during the strip-out phase will be loud — let your neighbours know in advance to avoid complaints.
Waterproofing Is Non-Negotiable
In an apartment, a waterproofing failure doesn't just damage your flat — it damages the flat below. This is the single most important reason to hire an experienced wetroom installer rather than a general handyman or basic tiler. If water leaks through the floor into a neighbour's apartment, you are responsible for the damage. Proper tanking with a tested membrane system (not just paint-on waterproofer from a DIY store) is essential.
Floor Build-Up Height
Creating the sloped screed layer adds height to the floor — typically 50–80 mm at the highest point. In older Prague apartments with low door thresholds, this can create a step up into the wetroom. Discuss this with your installer during the planning stage. Solutions include a ramped transition strip or lowering the existing subfloor (more expensive and disruptive).
How to Find a Wetroom Installer in Prague
Wetroom installation sits at the intersection of several trades: plumbing, tiling, waterproofing, and screeding. You have two main options:
- A specialist wetroom or bathroom installer who handles the entire project (most convenient, usually best results)
- Separate tradespeople — a plumber for drainage, a tiler for waterproofing and tiling — coordinated by you or a project manager
For most expats, a single installer who takes responsibility for the whole job is the better choice. It avoids the "that's not my problem" finger-pointing when something goes wrong between trades.
What to Ask Before Hiring
Before committing to any wetroom installer, ask these questions:
- Have you done wetrooms before? Ask to see photos of previous projects. A standard bathroom tiler may not have experience with floor gradients and tanking systems.
- What waterproofing system do you use? Look for recognised systems (Schlüter-DITRA, Mapei Mapegum, Rako System, or similar). Avoid anyone who says "I'll just use tile adhesive — it's waterproof enough."
- Do you have an IČO? An IČO (identifikační číslo osoby) is a Czech business registration number. You can verify it on ares.gov.cz, the official Czech business register. Working with a registered tradesperson gives you legal recourse if something goes wrong.
- Will you provide a written quote and contract? A smlouva o dílo should cover scope, price, payment schedule, timeline, and warranty terms.
- What guarantee do you offer on the waterproofing? Reputable installers typically guarantee their tanking work for 5–10 years.
Common Wetroom Mistakes to Avoid
These are the problems Prague bathroom installers see most often when fixing botched wetroom jobs:
- Insufficient floor gradient: Water pools instead of draining. The floor must slope consistently toward the drain — even 1 mm errors over a large floor become visible puddles.
- Skipping membrane on walls: Some installers only waterproof the floor. In a wetroom, walls receive direct water spray and must be tanked to at least 2 metres high, preferably full height.
- Wrong tile grout: Standard cement grout absorbs water over time. Epoxy grout or polymer-modified grout is essential in a wetroom.
- No threshold or drainage planning: Water escaping the wetroom into a hallway means the gradient or layout was wrong. A small lip, a well-placed linear drain near the door, or a glass screen solves this.
- Hiring on price alone: A wetroom done cheaply and badly will cost far more to fix than doing it properly the first time — especially in an apartment where water damage affects other units.
Wetroom vs. Walk-In Shower: Which Is Right for You?
Many people confuse wetrooms with walk-in showers. The difference matters for cost and planning:
- Walk-in shower: Uses a shower tray (often flush with the floor) and may have a glass screen. Only the shower area needs full waterproofing. Simpler and cheaper — typically 40,000–90,000 Kč installed.
- True wetroom: No tray. The entire room floor is sloped and waterproofed. More design freedom but higher cost and technical complexity.
If your main goal is removing a bathtub and getting a barrier-free shower, a walk-in shower with a flush tray may give you 80% of the wetroom look at half the cost. Discuss both options with your installer before committing.
