Wooden kitchen floors: finishes, durability and price

Øens HåndværkerCentralPublished August 16, 2026 · 11 min. read

Wooden floors in the kitchen hold up well when the surface treatment matches the wear and tear. Varnish provides the densest surface against water spills, and according to Gulvfakta from the Flooring Industry within Danish Industry, varnished floors can typically be used for a long time - often several years in homes - before needing re-varnishing. However, varnish usually requires re-varnishing the entire floor rather than spot repair. Oil is more vulnerable to water, and in high-traffic areas like kitchens, oil may require maintenance oil several times a year, but the area in front of the sink and stove can be treated separately.

The short overview

The choice for a kitchen floor essentially comes down to varnish and a hardening oil - varnish wins on durability, oil on repairability. Here are the differences summarised:

• Varnish: densest surface and minimal ongoing maintenance, but damage can rarely be repaired locally. Gulvfakta states that varnish usually requires re-varnishing the entire floor.
• Oil: can be spot-repaired in front of the sink and stove. However, heavily used areas like kitchens may require maintenance oil several times a year, according to Gulvfakta.
• Soap and lye: lye is a pre-treatment, not a finish, and must be followed by oil or soap. Træinformation's TRÆfakta 09 describes lye treatment primarily as a method for softwood floors.
• Price: Øens HåndværkerCentral operates with fixed package prices based on area - from DKK 3.700 for 1-15 m² to DKK 175 per m² for 36 m² and above, all inclusive of VAT.
• The real enemy is moisture, not wear: a 1 percentage point change in wood's moisture content results in approximately 0.15% radial movement and 0.30% tangential movement, according to Gulvfakta.

Can you have a wooden floor in the kitchen?

Yes. The kitchen is simply one of the most heavily trafficked rooms in the house, and the treatment must take this into account. Gulvfakta from Gulvbranchen (DI) explicitly mentions kitchens and hallways as heavily used areas where an oiled floor might require maintenance oil several times a year.

On the other hand, wooden flooring has an advantage that no vinyl or laminate board has: it can be sanded and given a completely new surface. How many times depends not on a fixed quota, but on how much wood remains above the tongue and groove. A kitchen floor with 15 years of cooking behind it is therefore rarely a floor that needs to be torn up. It is a floor that needs to be sanded and re-treated.

What treatment should a wooden kitchen floor have?

The choice is between four surfaces: varnish, oil, soap, and lye. Varnish forms a dense film on top of the wood, oil saturates the fibres from within, soap provides an open and bright surface, and lye is a pre-treatment that slows down the wood's yellowing. In a kitchen, the choice effectively comes down to varnish and a hardening oil.

The methods behind each treatment are described in Træinformation's TRÆfakta sheets on wooden floors - no. 07 on varnishing, no. 08 on oil treatment, and no. 09 on lye treatment.

Is oil or varnish best for a kitchen?

Varnish wins on wear resistance, oil wins on repairability. A varnished surface tolerates water spills best, and Gulvfakta from Gulvbranchen (DI) describes that varnished floors can usually be used for a long time before needing re-varnishing. The disadvantage is stated in the same source: varnish usually requires re-varnishing of the entire floor, while oil can be partially repaired in high-traffic areas.

Oil, therefore, goes the opposite way. The surface is not as dense, but the area in front of the sink, where the floor always wears first, can be treated separately without affecting the rest of the kitchen. If you have an open-plan kitchen/dining area where the dining part looks fine but the work zone is dull and grey, oil is clearly the most economical choice over time. We delve deeper into the pros and cons in the guide on varnishing versus oiling a wooden floor.

How often should a kitchen floor be treated?

An oiled kitchen floor needs maintenance oil far more often than a varnished one. Gulvfakta from the Danish Flooring Association (DI) states that heavily used areas like kitchens and hallways may require maintenance oil several times a year, while varnished floors can usually be used for a long time - often several years in homes - before needing re-varnishing.

The difference is not more or less work, but work distributed differently. The oiled floor receives many small treatments that you can manage yourself with maintenance oil and a polishing machine, without clearing the kitchen. The varnished floor receives no ongoing care - but on the other hand, a full re-varnishing or sanding, where the kitchen must be emptied, and the room cannot be used for a couple of days. The guide on maintenance of oiled wooden floors reviews the routine step by step.

Drying times are worth planning for: oil requires about one day before light use, while varnish needs 1-3 days depending on the number of coats. For hardening oil, excess oil must be removed with cotton cloths within the time specified by the supplier - approximately 20-30 minutes, according to Gulvfakta. If you wait longer, sticky patches will remain.

How much does sanding and treating a kitchen floor cost?

Øens HåndværkerCentral charges a fixed package price based on area: DKK 3.700 for 1-15 m², DKK 5.700 for 16-25 m², DKK 6.700 for 26-35 m², and DKK 175 per m² from 36 m² - all including VAT. Because the smallest intervals are fixed amounts, the price per square metre drops significantly the larger the contiguous area you sand.

Calculation examples for the last row: 45 m² costs DKK 7.875, 65 m² costs DKK 11.375, and 80 m² costs DKK 14.000. In addition, there are surcharges for planing (DKK 50 per m²), stair treads (DKK 300 per piece), and door sills (DKK 200 per piece). The current rates are listed in Øens HåndværkerCentral's price overview for floor sanding.

These figures are also the best argument for sanding the entire contiguous area at once. A kitchen of 14 m² alone costs DKK 3.700, or about DKK 264 per m², while the same amount of money goes much further if the dining area is included. Added to this is the craftsmanship: if you only sand the kitchen area, you will have a visible transition in the middle of the floor, because new and old surfaces will never have the same sheen. You will receive a fixed price before the work begins, a response within 24 hours, and the job is covered by a workmanship guarantee on the work performed. More price examples can be found in the guide on what floor sanding costs.

How do you protect the floor from water and stains?

Water is more dangerous for a kitchen floor than shoes and chair legs, because the wood moves with moisture. Gulvfakta from the Flooring Industry (DI), in its example, considers a parquet floor with 65 mm wide staves, delivered from the factory with an average moisture content of 8%. In late summer, which is typically the most humid period, air humidity can reach approximately 65% RH, and the wood's moisture content rises to 12-13%.

Wood changes size as its moisture content changes. Gulvfakta gives approximate movement figures of 0.15% radially and 0.30% tangentially for each percentage-point change in moisture content. The actual movement depends on the grain direction, floor construction and conditions; it should not be treated as a single fixed expansion figure for every kitchen. Three practical measures help:

1. Wipe up spills immediately - especially under the dishwasher, where a slow drip can go unnoticed for weeks.
2. Place a dense mat in front of the sink area, not an absorbent cotton rug.
3. Keep an eye on the gaps between the boards in winter. If they become very wide, the air in the house is too dry.

If the damage has occurred, dark rings and water stains can often be remedied. See the procedure in the guide on removing stains from wooden floors, and review the daily routine in the guide on washing and cleaning wooden floors.

Can you sand the kitchen floor yourself?

You can rent a floor sander, but the kitchen is the most difficult surface in the home to practice on. You have to sand right up to kitchen cabinets, plinths and appliances, and a belt sander that stays still for two seconds too long on a soft pine floor leaves a hollow that no treatment can hide afterwards.

Then there's the dust. Hardwood dust - beech, oak, ash, cherry, and exotic wood species - is on the list of carcinogenic work processes in the Danish Working Environment Authority's guideline C.2.1 and in appendix 2 of the Cancer Order. Softwood dust in high concentrations over extended periods is also covered by the list. If air with this type of dust needs to be cleaned at a changing workplace, the Danish Working Environment Authority recommends a dust extractor in dust class H designed according to DS/EN 60335-2-69, while class M or L is only sufficient for dust that is not carcinogenic. Professional equipment extracts dust during the sanding itself instead of swirling it into the kitchen, where it settles in cabinets and on food. The trade-off is described in the guide on sanding floors yourself or professionally.

Re-treatment with oil, on the other hand, is a realistic DIY task once the floor has been sanded down and properly treated by a professional.

What about underfloor heating and engineered wood flooring in the kitchen?

Both can be sanded, but the thickness of the wear layer sets the limit - not the number of previous sandings. Gulvfakta from Gulvbranchen (DI) is specific: engineered floors with a wear layer of 2 mm and below should not be sanded. On a solid floor, you measure the remaining thickness with a thin metal blade in the tongue and groove joint before deciding. If there is only very little left, a light sanding is often the only responsible option.

Underfloor heating is also not an obstacle, but it requires careful management: the heat is turned down before sanding and gradually increased afterwards, so the wood doesn't dry too quickly. Træinformation's TRÆfakta 14 on wooden floors and indoor climate specifically addresses the interaction between heat, humidity, and wooden floors. See the details in the guides on underfloor heating and floor sanding and on how many times a wooden floor can be sanded.

If your solid wood kitchen worktop needs the same treatment as the floor, both can be done during the same visit - see sanding kitchen worktops.
