Tiling cost per m² in Finland: how to price a tiling job

Tiling cost per m² is worked out line by line from quantities. Measure floor and walls separately, work out tiles with waste and adhesive and grout from their consumption, multiply the area by labour hours and the hourly cost, and price drains, pipe penetrations and boxings per piece. In Finland, wet-room waterproofing is a line of its own.

What goes into the price of tiling per m²?

A finished square metre of tiling is made up of several tasks and materials. When each has its own line in the quote, you can see where the price comes from, and the client can see what they are paying for.

• Preparation: removing the old surface, priming, levelling and falls to the drain in wet rooms.
• Waterproofing: wet-room floor and walls, corner reinforcements, and the joints at pipe penetrations and the drain.
• Tiling: fixing the tiles, cutting and drilling.
• Grouting: grout and silicone in movement joints.
• Details: floor drains, pipe penetrations, boxings, niches, corner trims and thresholds.
• Materials: tiles with waste, tile adhesive, grout, the waterproofing system and primers.
• Other costs: protection, cleaning, waste, transport and travel.

How do you calculate the price of a tiling job?

Work through the tiling in the same order every time, and no line gets left out.

1. Measure each surface separately. The floor, the walls and the waterproofed surfaces are different quantities. Deduct doors and windows from the walls. The tiled area is the finished surface, not the tiles you buy.
2. Count details per piece. Drains, pipe penetrations, boxings, niches and external corners take time that the square metres do not show.
3. Choose the labour consumption. Labour consumption is hours per square metre, and it depends on the tile size, the laying pattern and whether the surface is a floor or a wall. Rakennustieto’s Rakennustöiden menekit collects the Ratu data on labour and material consumption for new build and renovation. After that, the hours you have recorded on your own jobs are the best benchmark.
4. Work out materials from consumption. Tiles are bought as area times waste, rounded up to whole boxes. The consumption per square metre of adhesive, grout and waterproofing is in the product’s technical data sheet.
5. Base waste on your own jobs. Waste varies a lot from job to job. In a study by Formoso, Soibelman, De Cesare and Isatto (2002), material waste was measured on 74 building sites, and it varied widely between projects. One fixed percentage for every job does not work.
6. Add other costs, overheads and margin. Keep unit prices current. In Statistics Finland’s building cost index, labour costs rose 3.3% and surface materials 3.7% in the year to September 2026.

As formulas:

What you calculate	Formula
Tiles to buy	area × (1 + waste), rounded up to whole boxes
Grout	(A + B) ÷ (A × B) × joint width × joint depth × area × density
Tile adhesive	area × consumption (kg/m²) from the product’s technical data sheet
Labour hours	area × labour consumption (h/m²) + details × hours per piece
Price per m²	(materials + labour + other costs) ÷ tiled area

In the grout formula, A and B are the tile’s side lengths in metres. The formula gives the joint length per square metre; multiplied by the joint width and depth, it gives the volume of grout.

How much tile and grout does a 2 × 2.5 m bathroom need?

The walls are tiled up to the ceiling, and the room is 2.5 m high. The wall area is the perimeter of 9.0 m times 2.5 m, which is 22.5 m², minus the door at 0.8 × 2.1 m = 1.68 m². That leaves 20.8 m² of wall to tile.

The wall tile is 300 × 600 mm, and a box holds 1.44 m². With 10% waste, you need 20.8 × 1.10 = 22.9 m² of tile, or 22.9 ÷ 1.44 = 15.9 boxes, so 16 boxes in practice.

For your own job, the tile calculator works out the tiles in boxes and the bags of tile adhesive and grout.

The joint length per square metre is (0.3 + 0.6) ÷ (0.3 × 0.6) = 5.0 m. With joints 3 mm wide and 8 mm deep, that takes 5.0 × 0.003 × 0.008 = 0.00012 m³, or 0.12 litres of grout per square metre and about 2.5 litres for all the walls. Multiply the litres by the product’s density to get kilograms.

Labour hours are calculated from 20.8 m², not 22.9 m², because waste does not add to the surface being tiled. The floor gets its own line, since its tile, falls and labour consumption are different.

Why is one square-metre rate not enough for a bathroom?

A small bathroom has many details for its area. The drain, a boxing, a niche and each pipe penetration take the same time whether the room is 3 or 8 square metres. Hide them in the square-metre rate and the small room makes a loss while the large one is priced too high.

So the quote should have square-metre rates for the floor and the walls and prices per piece for the details. Small tiles, mosaic and diagonal patterns raise the labour consumption, so they need a labour consumption figure of their own.

What does Finnish law require of wet-room waterproofing?

A wet room must be waterproofed. Under the Ministry of the Environment’s decree 782/2017, the structure behind surfaces exposed to running water, repeated splashing or condensation must be waterproofed. The waterproofing must also be watertight at joints, penetrations and junctions, the floor must fall towards the floor drain, and the joint between the waterproofing and the drain must be tight. The decree also applies to renovation work.

Price this work on lines of its own: waterproofing in square metres for the floor and walls, the falls, and a price per piece for pipe penetrations and the drain connection. Under the decree, the walls of a separate toilet do not need waterproofing, so the waterproofed area is not always the same as the tiled area.

According to Finance Finland, insurers pay about €160 million a year in compensation for water leak damage, on about 37,000 claims. In Finance Finland’s water leak study (Haapaniemi 2014), the most common reason for a refused claim was a construction, workmanship, design or installation error. A leak caused by faulty work can fall outside the insurance.

Why show the labour share separately?

Consumers in Finland get the household deduction (kotitalousvähennys) only for labour. According to the Tax Administration’s guidance, the invoice states the deductible work separately from other items such as supplies and travel. The deduction also requires the company that did the work to be in the prepayment register.

When the tiling quote splits out labour, tiles, adhesive and grout, the client sees at once what the deduction covers. The rest of the quote, such as the type of price, VAT and contract terms, is covered in the guide to the contractor quote template.

Which lines get left out of tiling quotes?

These lines are easy to leave out, and every missing line is paid for out of your own margin:

• removing old tiles and waterproofing, and the demolition waste
• levelling the substrate and correcting the falls
• drying times for waterproofing and levelling compound that lengthen the job
• corner reinforcements and pipe collars
• silicone in movement joints
• corner trims and the threshold
• holes for pipes and fittings
• cutting tiles and carrying them upstairs
• protection, dust control and final cleaning
