Bathroom Renovation in Prague: Complete Expat Checklist

A bathroom renovation in Prague as an expat means navigating unfamiliar trades, Czech-specific regulations, and a language barrier — all while trying to get a quality result on budget. This checklist walks you through every step, from initial planning to final sign-off, so nothing falls through the cracks.

Whether you're updating a tired panelák bathroom or gutting and rebuilding in a historic apartment, this guide gives you a structured, actionable plan you can follow from day one.

Before You Start: Planning Your Prague Bathroom Renovation

Rushing into a bathroom renovation without a plan is the single biggest source of budget blowouts and delays. Before you contact a single tradesperson, work through these planning steps first.

Define Scope and Priorities

Be honest about what you actually need versus what you want. A full gut renovation (ripping everything back to bare walls and replacing all plumbing and electrics) is a fundamentally different project from a cosmetic refresh (new tiles, fixtures, paint). Your scope determines your budget, timeline, and which trades you need.

• Cosmetic refresh: New tiles, fixtures, vanity, mirror, paint. Typically 2–4 weeks.
• Partial renovation: New layout for some fixtures, updated plumbing or electrics, waterproofing. Typically 3–6 weeks.
• Full gut renovation: Everything stripped, new plumbing risers, new electrics, new waterproofing, new everything. Typically 4–8 weeks.

Check Your Lease or SVJ Rules

If you're renting, you need written permission from your landlord — ideally specifying what work is allowed and who pays. If you own a flat in a bytový dům (apartment building), your SVJ (společenství vlastníků jednotek — the owners' association) may have rules about noise hours, construction debris removal, and modifications to shared infrastructure like waste stacks or water risers.

Many Prague SVJs require you to submit a written notification (or even a formal request for approval) before any renovation that involves plumbing or structural changes. Ignoring this can result in fines or being ordered to reverse the work.

Do You Need a Building Permit?

Most standard bathroom renovations — replacing tiles, fixtures, and updating plumbing within the same layout — do not require a building permit (stavební povolení) in the Czech Republic. However, if you're changing the layout significantly, moving load-bearing walls, or altering shared building infrastructure, you may need at least an ohlášení (notification to the building authority).

When in doubt, consult your local stavební úřad (building authority) or hire a project manager who understands Czech construction regulations. This is especially important in Prague's historic districts (Prague 1, 2, parts of 3 and 7), where heritage protection rules may apply.

Your Step-by-Step Bathroom Renovation Checklist

Use this numbered checklist as your master plan. Print it, save it, refer back to it throughout your project.

1. Set your budget range. Bathroom renovations in Prague typically range from 80 000 Kč for a basic cosmetic update to 400 000+ Kč for a full gut renovation. Add a 10–15% contingency for surprises — especially in older buildings.
2. Get at least 3 quotes. Never accept the first quote. Post your job and compare pricing, scope, and communication quality across multiple tradespeople.
3. Check SVJ rules and get landlord approval (if applicable).
4. Confirm permit requirements with your local building authority.
5. Choose your materials and fixtures before work starts — tiles, shower tray/bathtub, toilet, vanity, taps, mirror, lighting. Delays in material delivery are the #1 cause of timeline overruns.
6. Agree on a written contract (smlouva o dílo) with your chosen tradesperson or team. This should include scope, price, payment schedule, timeline, and warranty terms.
7. Schedule the trades in order: demolition → plumbing rough-in → electrical rough-in → waterproofing → tiling → fixture installation → painting → final clean.
8. Arrange water and electricity shutoffs with your SVJ or building manager — your neighbours need advance notice.
9. Plan for debris removal. Prague requires construction waste (stavební odpad) to be disposed of properly. Your tradesperson should handle this, but confirm it's included in the quote.
10. Do a final walkthrough before making the last payment. Check every fixture, every tile, every seal. Test hot and cold water, drainage, and all electrical outlets.

Which Trades Do You Need for a Bathroom Renovation?

A bathroom renovation in Prague typically requires multiple specialist trades. Understanding who does what helps you plan the schedule and avoid paying one trade to wait for another.

• Demolition / removal: Stripping old tiles, removing old fixtures, disposing of waste.
• Plumber (instalatér): Moving or replacing water supply pipes, waste pipes, connecting shower/bath, toilet, basin. Find a plumber on TraderPoint.
• Electrician (elektrikář): Bathroom electrics must meet Czech safety standards (ČSN). Zones around water sources dictate what can be installed where. Find an electrician on TraderPoint.
• Waterproofing specialist: Applying hydroizolace (liquid or sheet membrane) under tiles in wet areas. This is non-negotiable — skipping it leads to water damage, mould, and disputes with neighbours below you.
• Tiler (obkladač): Wall and floor tiling. Quality tiling is one of the most visible parts of a bathroom renovation. Find a tiler on TraderPoint.
• Painter: Ceiling and any non-tiled wall surfaces. Find a painter on TraderPoint.
• Bathroom fitter / general contractor: Some professionals handle the entire project end-to-end. This simplifies coordination but make sure you understand exactly what's included. Find a bathroom fitter on TraderPoint.

Some experienced bathroom fitters in Prague can handle plumbing, tiling, and basic electrics themselves. If you go this route, confirm they hold the relevant Czech trade licences (živnostenský list) for regulated trades like plumbing and electrical work.

Common Mistakes Expats Make with Prague Bathroom Renovations

After helping connect thousands of expats with tradespeople across Prague, certain patterns emerge. These are the mistakes that cost people money and time.

1. No Written Contract

A handshake deal with a tradesperson — even one recommended by a friend — is a recipe for disputes. Always insist on a smlouva o dílo (contract for work). It should clearly state the scope, total price, payment milestones, start and end dates, and what happens if work is delayed or defective.

2. Paying Everything Upfront

A reasonable payment structure is: 10–30% deposit, progress payments tied to milestones, and 10–15% held back until final walkthrough and approval. Any tradesperson demanding full payment before starting work is a red flag.

3. Skipping Waterproofing

In older Prague buildings — especially paneláky and pre-war apartments — waterproofing under tiles is essential. Water seeping through tiles and into the floor slab causes damage to your flat and the one below. Proper hydroizolace (waterproofing membrane) typically adds 5 000–15 000 Kč to the project but can save you tens of thousands in damage claims.

4. Not Checking the IČO

Every legitimate Czech business has an IČO (identification number). You can verify it on the official Czech business register at ares.gov.cz. This doesn't guarantee quality of work, but it confirms the business is legally registered — an important baseline check.

5. Choosing on Price Alone

The cheapest quote often becomes the most expensive project. A low bid may mean corners will be cut on waterproofing, materials, or finishing. Compare quotes on scope and detail, not just the bottom line number.

Materials and Fixtures: Where to Buy in Prague

Prague has a wide range of bathroom material suppliers. You don't need to speak Czech to shop at most of them — many larger stores have English-speaking staff or at least product labels you can research online beforehand.

• Large DIY chains: Hornbach, Bauhaus, and OBI stock tiles, fixtures, and accessories. Good for standard ranges at competitive prices.
• Specialist tile showrooms: Prague has dedicated tile showrooms (obklady a dlažby) in areas like Průmyslová, Čestlice, and across Prague 9 and 10. These offer wider ranges and expert advice.
• Sanitary ware shops: SIKO, Ptáček, and similar chains specialise in bathroom fixtures — toilets, vanities, showers, bathtubs. Many have showrooms where you can see products in person.
• Online ordering: Czech e-shops like mall.cz, eboard.cz, or direct from manufacturers. Delivery to Prague is usually 1–3 working days.

Pro tip: Buy 10–15% extra tiles beyond what you need. Matching tiles from the same batch later is often impossible, and you'll need spares for cuts, breakages, and future repairs.

Coordinating Trades: The Order That Matters

Getting the sequence wrong is one of the fastest ways to blow your timeline. Here's the standard order for a full bathroom renovation in Prague:

1. Demolition and strip-out — Remove old tiles, fixtures, and fittings. Inspect the substrate for damage or mould.
2. Plumbing rough-in — Install or relocate water supply and waste pipes. This must happen before walls are closed up.
3. Electrical rough-in — Run new cables for lighting, heated mirrors, towel rail, ventilation fan, and any sockets (remember Czech bathroom zoning rules).
4. Wall and floor preparation — Repair substrate, level floors if needed (self-levelling screed is common in Prague apartments).
5. Waterproofing (hydroizolace) — Apply to shower area, around the bath, and ideally the entire floor.
6. Tiling — Walls first, then floors. Grouting after tiles have set.
7. Second-fix plumbing — Install toilet, basin, taps, shower head, bath.
8. Second-fix electrical — Install light fixtures, switches, heated towel rail connection.
9. Painting and finishing — Ceiling paint, silicone sealing around fixtures, mirror mounting.
10. Final clean and snagging — Walk through, test everything, create a snag list of any issues.
