How Much Does It Cost to Renovate a Bathroom in a Bloc Apartment, and What's Involved?
Citeste articolul in romana → Renovare baie de bloc: cat costa, cat dureaza si ce presupune
In 2026, a full renovation of a typical 3–4 m² bloc bathroom costs roughly 10,000–25,000 lei (about €2,000–5,000), labour and materials included, and takes two to three weeks of work. The bathroom stays where it is: the pipes keep their routes, and the fixtures stay put or move slightly. None of this needs a notification unless the building's main stack (the riser) is touched.
In short
Full renovation, same layout: roughly 10,000–25,000 lei, two to three weeks of work.
Fixtures can shift slightly. The toilet is the hardest to move; the basin and washing machine are the easiest. Moving the bathroom itself is a different job.
Labour is usually 30–50% of the total. Removing the rubble is often billed separately.
The parts that matter most are the ones you won't see: the pipes up to the riser, the waterproofing and the electrics. Don't save money there.
No notification needed for fixtures, finishes and pipes inside your bathroom, even if a fixture shifts (Law 169/2026, art. 299 alin. (2) lit. a) pct. 7 and 9). The exception is work on the riser, which belongs to the association.
Leave access to the riser, and remember that a leak from your bathroom is your bill (Law 196/2018, art. 30(4)–(5)).
How much does a bathroom renovation cost in 2026?
For a typical 3–4 m² bloc bathroom, roughly 10,000–25,000 lei with standard finishes, and more with premium ones.
What's included: everything back to the concrete, new pipes along the existing routes, electrics, waterproofing, tiles and fixtures.
By finish level, in Bucharest:
Standard finishes: roughly 10,000–25,000 lei (about €2,000–5,000).
Premium finishes: large-format tiles, a built-in WC frame, glass shower walls, designer taps. Upwards of 25,000 lei, and over 40,000 lei at the top end.
All-in per m²: roughly 1,500–4,000 lei/m² of floor, labour and standard materials included.
Shifting a fixture adds plumbing work and sometimes a higher floor, so expect the upper half of the range. Moving the bathroom to another room has its own limits and costs;
What do labour and materials cost?
Labour is usually 30–50% of the total. Tiles and fixtures are where your choices move the price most.
Labour, Bucharest, 2026:
Removing old tiles: roughly 13–25 lei/m².
Laying tiles, standard sizes (30×30, 40×40 cm): roughly 65–90 lei/m².
Laying large-format or rectified tiles (60×60 cm and up): roughly 100–150 lei/m².
Liquid waterproofing: roughly 50–90 lei/m² of labour.
Extractor fan installation: from about 150 lei, plus the fan.
Rubble removal: often billed separately, roughly 500–3,000 lei depending on access and volume.
Materials, typical ranges:
Tiles: 100–500 lei/m². A 3–4 m² bathroom tiled floor-to-ceiling needs roughly 20 m².
Adhesive and grout: 300–800 lei.
Waterproofing materials: 400–800 lei.
Bathtub: 1,000–3,000 lei. Shower enclosure: 2,000–3,000 lei.
Toilet: 500–1,500 lei. Washbasin: 300–1,000 lei. Taps: 600–2,000 lei.
Where to save: the tiles, the basin and the taps. Where not to: the pipes, the waterproofing and the electrics. They're covered by tiles, and fixing them later means breaking the tiles.
Can you move the fixtures within the bathroom?
A little, yes. How far each one can go depends on its drain and on how far it sits from the riser.
Toilet: the hardest. Its drain is the largest pipe and has to reach the riser with a steady fall, so it usually stays where it is or moves a short distance along the same wall.
Shower or tub: can usually shift within the room. The drain needs a fall, and a new position may mean raising the floor a few centimetres.
Basin and washing machine: the easiest. Small drains, and the pipes can run in boxing along the wall.
Swapping the tub for a shower is the most common shift, and usually the one that makes room for the washing machine. Anything beyond the bathroom's walls is a move, not a renovation.
What does a full bathroom renovation involve, step by step?
Seven stages, in a fixed order. The ones in the middle decide whether the bathroom lasts.
Strip-out (1–2 days). Tiles, fixtures and old pipes come out; rubble goes down to a container.
Pipes and electrics (2–3 days). New water and drain pipes along the existing routes, from your fixtures up to the connection with the riser. A dedicated bathroom circuit with an RCD (protectie diferentiala) and earthing; cabling for the fan and lights.
Walls and floor (1–3 days). Levelling the walls and, if needed, a new screed (sapa) to set the floor height and the fall towards the shower drain.
Waterproofing (1–2 days, plus drying). A liquid membrane in at least two coats on the floor and up the walls in the shower area, with tape in every corner and around every pipe. Ask for a water test before tiling.
Tiling (3–5 days). Floor and walls, then grouting.
Fit-out (1–2 days). WC, basin, taps, shower or tub, fan, lights, mirror, silicone.
Measure for the shower glass. Made-to-measure glass is measured after tiling and often takes a week or more to arrive, so plan for a few days without the screen.
Order everything before the strip-out: tiles, fixtures, taps. A crew waiting for a delivery is the most common reason a two-week job takes five.
How long does it take?
Two to three weeks of work, with a coordinated crew and materials on site.
The works: two to three weeks, including drying times.
Before the start: allow time to choose and order the materials, so they're on site on day one.
Without a working bathroom: plan where you'll shower for those weeks. In a one-bathroom flat, many people stay with family or rent short-term.
Do you need approval to renovate a bathroom?
No, as long as you don't touch the building's riser. Everything inside your bathroom, up to the connection with the riser, is yours to renovate without paperwork.
Fixtures, finishes and your own pipes, even with a fixture shifted within the room: no notification or permit. Replacing finishes, floors and interior installations needs no formality (Law 169/2026, art. 299 alin. (2) lit. a) pct. 7 and 9).
The riser is different. It's shared property, so work on it is the association's decision, not yours (see "The riser behind the panel" below).
Moving the bathroom to another room is a different job with its own approval route: see #9.
Either way, check the association's rules on hours for noisy work, and tell the neighbour below (see below).

What's different about a bloc bathroom?
Five things a crew used to houses can get wrong: the riser, the walls, the ventilation duct, the floor and the neighbour below.
The riser behind the panel
The water and drain risers (coloane) usually run in a shaft behind a panel next to the WC or basin. They're common property (Law 196/2018, art. 35(1)(e)), so they belong to the association, not to you.
Have the plumber check the riser and its connection while the wall is open. If it's in poor condition, raise it with the association before you tile. Replacing it later means breaking your new tiles.
Don't let your crew replace or reroute the riser on their own. Changing shared installations needs a technical report from the utility provider, a two-thirds vote of the general assembly and city hall approval (Law 196/2018, art. 37(6)).
Never tile the panel shut. The association can ask to reach the riser through your flat with five days' written notice, or 24 hours in an emergency (art. 31(1)). The law has the association pay to restore your finishes afterwards (art. 31(3) and (6)), but you'd still be waiting for the repair. Fit a removable access panel and avoid all of it.
The walls
Bloc bathrooms often have thin partition walls, and in some buildings prefabricated ones. What they can carry varies, so have the wall checked before you choose a wall-hung toilet frame, heavy large-format tiles or tall cabinets.
Don't let anyone cut channels into a concrete panel wall or the floor slab for pipes. Those are structural. Run pipes in boxing or in the floor build-up instead.
The ventilation duct
Most bloc bathrooms vent into a shared vertical duct behind a grille. Fit a quiet extractor fan with a non-return valve into the existing duct. The valve stops your neighbours' air from coming back into your bathroom. A humidity sensor or a run-on timer keeps it running after a shower.
The floor
The drain height is fixed by the riser connection, and you can't cut into the slab. So a level-access walk-in shower usually means raising the bathroom floor a few centimetres or using a low shower tray. Check the door threshold and ceiling height before you commit.
What about leaks and the neighbour below?
Your bathroom's pipes and waterproofing are your responsibility, and so is any damage they cause downstairs.
You must keep your own installations in working order so they don't damage others (Law 196/2018, art. 30(4)).
If your leak damages a neighbour's flat or the common parts, you repair it or pay for it (art. 30(5)).
Insurance: the mandatory home policy (PAD) covers earthquakes, landslides and floods, not water from pipes. An optional home policy covers water damage and, if you choose it, your liability to neighbours. For a small flat it's typically a few hundred lei a year.
Before you start: tell the neighbour below, and photograph their bathroom ceiling with them. If anything appears later, you'll both know what was there before.
Tub or shower?
It depends on who lives there. In a 3–4 m² bathroom, the choice decides whether the washing machine fits.
Shower (e.g. 90×120 cm): frees space, often enough for the washing machine. Easier to step into as you get older; easier to clean. Needs a good fall to the drain and glass that's measured after tiling.
Tub (usually 150–170 cm): bathing small children, a long soak, and what many family buyers expect when you sell. Takes the whole short wall.
Tub with a shower screen: the compromise when you want both and the room only allows one.
What should a bathroom quote include?
Hold every quote against this list. Anything missing is either excluded or will come back as an extra.
Strip-out and rubble removal (who pays for the container)
Water and drain pipes up to the riser connection, and what pipe material
Any fixture that shifts, and what that adds (pipework, floor height)
Electrics: dedicated circuit, RCD, earthing, fan and lighting points
Waterproofing: product, number of coats, how high up the walls, corner tape, and a water test before tiling
Screed or levelling, if needed
Tiling by m², with any surcharge for large-format tiles
Fit-out of every fixture, and silicone
A removable access panel for the riser
Who buys the materials, and when they need to be on site
Start date, duration and payment stages
A written warranty and an invoice
A typical case
A composite example, not a specific client.
A couple owns a two-room flat in a 1980s panel bloc. The bathroom is 3.5 m², with the original tiles, a tub, steel pipes and no fan. The washing machine lives in the hallway.
What they do:
Full renovation, same layout, with no paperwork. They order the tiles and fixtures before the crew starts.
The tub becomes a 90×120 cm shower in the same corner, on the same drain, and the washing machine moves into the freed space, sharing the basin's connections. The toilet stays where it is.
The plumber finds the drain riser in fair condition and leaves it alone. The new pipes follow the old routes and stop at the riser connection, behind a removable access panel.
A fan with a non-return valve goes into the existing duct.
The floor goes up 3 cm to give the shower drain its fall, and the door is trimmed.
The result: two and a half weeks of works and roughly 13,000–20,000 lei with mid-range tiles and fixtures, inside the market range.
