The whole job costs from €3,000, with materials and plumbing fixtures separate in the estimate. The larger the room and the more complicated the work, the higher the price.
Why a bathroom is a separate job
In a bathroom, water reaches the floor and walls every time someone washes. That is why waterproofing is needed under the tiles, and the joints in corners and at plumbing fixtures must be flexible. If a layer is left out, water can get into the floor slab and appear on the neighbour's ceiling.
The second reason is the building's utilities. In an apartment building the risers are common property of the apartment owners, but the pipes from the riser to your fittings are part of the apartment. The bath, shower, toilet and sink belong to the apartment, and they can be changed without the neighbours' consent.

Order of work in a bathroom renovation
- Demolition The old tiles, bath, sink and toilet are removed, if they are being replaced. The condition of the walls and floor is revealed, and then you can see how much levelling is needed.
- Pipes and electrics If the water pipes are replaced or fittings are moved, this is done before any finishing. Electrical wiring is installed under the direction of a certified construction specialist, and when the wiring is rebuilt, residual current protection is installed.
- Preparing the base The walls and floors are levelled and primed. Ceresit states that a cement screed and plaster under tiles must be at least 28 days old with moisture below 4%.
- Waterproofing The manufacturer recommends applying Ceresit CL 51 in at least two coats. Waterproofing tape is worked into corners and joints, and collars are used around pipes and drains.
- Tiling and joints Tiles are fixed to a prepared surface; with Ceresit CM 17, the adhesive must cover at least 65% of the underside of the tile. In corners and at plumbing fixtures the joints are filled with silicone, not grout.
- Installing the plumbing After the grout has hardened, the bath or shower, sink, toilet and taps are installed. For Ceresit CE 40 grout, the manufacturer states water exposure after 24 hours.

What you decide
- Bath or shower: a shower with a drain at floor level needs the floor to slope towards the drain, more on the page shower with a floor drain.
- Tile size and pattern: large-format tiles and patterns cost more than a plain layout.
- Whether to replace the pipes up to the riser: old pipes under new tiles will have to be opened up later.
- Whether the risers have to be replaced now: they are common property, so replacement needs a decision of the apartment owners' association, and the building manager organises the work.
- Where the washing machine will go and whether it needs a socket.
- Whether you will choose the materials and plumbing fixtures yourself.
Leave access by the risers, for example a hatch. The owner must allow specialists authorised by the association or the building manager to carry out work to maintain the building's utilities, and a riser tiled over makes this difficult.

Ventilation in a bathroom
In residential buildings, bathrooms and toilets are ventilated through natural extract ducts. If a fan and a shared ventilation system are connected to the bathroom, the air ducts of the kitchen and sanitary rooms may only be connected each to its own duct. Natural ventilation ducts in an apartment are cleaned and inspected at least once every 10 years, and in rooms with gas appliances at least once every five years. If mirrors and walls stay damp for a long time after washing, check the duct before the renovation.

How much a bathroom renovation costs
Prices are for labour. Materials are calculated separately in the estimate. A bathroom renovation, all the work, costs from €3,000. If only a few jobs are needed, they are calculated line by line:
| Work | Price |
|---|---|
| Demolition of old tiles | from €9/m² |
| Waterproofing in a bathroom | from €6/m² |
| Tiling | from €24/m² |
| Floor drain installation | from €100 per drain |
| Replacing or installing a bath | from €130 per bath |
| Installing a toilet during a renovation | from €50 per toilet |
Example: tiling 18 m² × €24 = from €432, waterproofing 5 m² × €6 = from €30 and floor drain installation from €100, in total from €562. This covers only these three jobs, without demolition, levelling and plumbing.
Bathroom renovation costs: what they depend on
- the floor area in m² and the area of walls to be tiled;
- the condition of the walls and floor after demolition;
- whether the pipes, risers and electrical wiring are changed;
- the tile size and the number of corners;
- a shower with a drain or a bath.
