キッチン、バスルームなどに最適な石材の床材 5 種類

さまざまな種類の石の床は、現代的な家でもモダンな家でも、ほとんどの部屋に適しています。キッチンに天然石のタイルを敷くのは、実は最も人気のある外観の 1 つです。バスルームや廊下にも美しい選択肢になります。また、天然石の床が堅実な選択肢となるのは、外観だけではありません。

From the palest marble and limestone to the darkest slate and granite, the design possibilities of stone flooring are vast and many are very durable, making them one of the best types of flooring materials to choose if you want to add value and character to your property.

天然石はキッチンの床に適していますか?

キッチンに天然石の床材を使用すると、スタイルと機能性の両方が得られます。耐久性があり長持ちする花崗岩は、カウンタートップにもよく使用される人気の選択肢です。一方、石灰岩は温かみのある素朴な仕上がりで、簡単には摩耗しません。キッチンスペースに多くの人が出入りする場合に最適です。 

天然石のフローリングの費用はいくらですか?

Prices vary enormously and will depend on the grade and quality of the stone. But, this is usually one of the downsides to natural stone flooring as prices compared to other types of floor tiles are elevated. Most stone is newly quarried but reclaimed slabs are available, which, although considered more environmentally friendly, are usually more expensive. Expect to pay upwards of £30 per m² from a high-street or national retailer and up to and over £500 per m² for high-grade or rarer stones. 

米国では、設置だけで 8 ドルから 18 ドル程度の費用がかかります。デザインがユニークであればあるほど、費用は高くなります。

床材に最適な石材はどれですか?

Stone floors are widely considered to add value to a property, but choose wisely as once laid you won’t want to change them for years. The most durable option is granite while many would say that marble is the most popular (albeit expensive) option.

1. 花崗岩

幅広い色彩があり、鉱物の斑点や微妙な縞模様が見られることが多い花崗岩は、ほとんどの住宅スタイルに適応できる柔軟な選択肢です。また、非常に耐久性が高いため、廊下などの人通りの多い場所でも使用できます。仕上げはさまざまですが、色や模様が完全に現れるのは磨き仕上げです。色は青や紫から灰色、オリーブグリーンまでさまざまで、錆びた赤い模様が付いていることもよくあります。

Granite floor tiles typically cost from £30 per m²/ $4/sq. ft. ($4 /case)for basic and uniform, black small format tiles. Expect to pay, on average, between £50-£70 per m²/ $14 for larger format tiles, that have a more interesting and colorful finish. The limitless variations of granite flooring colors and textures means that it is hard to put a price on some of the rare examples available. It is very possible to spend in excess of £150 per m²/$200 /sq.ft to find the perfect patterning for your floor.

2. スレート

スレートはさまざまな厚さに簡単に分割でき、テクスチャ仕上げも用意されているため、浴室やキッチンなどの湿気の多い場所に最適です (誰が調理するかによって異なります)。

Slate sits at the cheaper end of the spectrum, costing as little as £10 per m²/$3.49/sq. ft. ($34.89 /case) from a high street or online supplier, up to £50 per m²/$11.00/sq. ft. for interesting colors and textures from specialist suppliers.

3. 大理石

大理石は石灰岩として始まり、特定の条件下でその成分が結晶化して大理石特有の縞模様を形成します。最も純粋な形では、さまざまな灰色から緑や黒まで、さまざまな色合いで見つかります。

Marble floors come in at a similar price to granite, with an equal number of variations in color and texture on the market. It's as great in a kitchen as it is in a bathroom. Expect to pay from £50 per m²/$10.99/sq. ft for the most basic tile, to as much as £150 or £200 per m/$77.42/sq. ft. ($232.25 /case)² for decorative tiles or tiles with specialist color-ways and finishes.

4. 石灰岩

Occurring in many tones, from nearly white to the more common warm honey, as well as rarer greys and dark browns Limestone is often a rustic. Textures range from even-grained stones through to smoother types with fossils and coarser, open-textured varieties. Some can be polished to resemble marble. It can scratch easily as it's quite soft so be careful in kitchens. However, as it's resistant to mold and bacteria, it works really well as a bathroom flooring option.

There is a lot of variation in the price of limestone tiles. The cheapest you will come across are around £30 per m² for a basic option, the average price is between £50 – £80 per m²/ $2-$11 per sq. ft, but much like granite and marble, you can end up spending up to £200 per m²/($200.00 /case)².

5. トラバーチン

トラバーチンは多孔質の表面で小さな穴があり、スポンジのような外観をしています。高級なトラバーチンは穴が少なく、より鮮やかな色をしています。一部のサプライヤーからは充填済みの状態で入手できますが、そうでない場合は現場で充填する必要があります。正しく設置すれば、トラバーチンはバスルームやシャワー用の最も耐久性の高い石材の 1 つです。

The cheapest travertine options are very affordable, starting from around £15 to £30 per m²/$468/case and giving a similar effect to limestone. The most you will look at spending on travertine tiles is around £70 per m²/ $50.30/sq. ft, $133.02 /case.

タイルにはどの天然石仕上げを選ぶべきでしょうか?

選択した仕上げはタイルの全体的な外観に影響し、結果として部屋の外観にも影響します。この用語集では、床タイルの仕上げについて説明します。

• 研ぎ澄まされた – a smooth, matt surface for a natural look.
• 転落 – an aged or distressed finish created by the tumbling process, which uses a machine with water and stones to give softer edges.
• リヴェン – stone, usually slate, is split to expose the natural texture for a rustic look.
• ブラシ仕上げ – a finish that is created by stiff bristles for a slightly rough appearance.
• ハンマーで打たれた – the surface has been finished with a pocked effect.
• 枕付き – a description used for stone that has soft, rounded edges.
• 磨き上げられた – smoothed for a glossy finish.
• 炎上 – a textured, non-reflective surface produced by a flame; sometimes referred to as a thermal finish.

石の床の欠点は何ですか?

自宅に天然石の床材を敷くことを検討する際に注意すべき点は、コストとメンテナンスです。石の種類によっては、多孔質で色あせやひび割れのリスクがあるため、より定期的なシーリングが必要です。また、石の床材によっては他の石材よりも傷がつきやすいため、耐久性にも注意する必要があります。さらに、石材の除去は非常に困難で費用もかかります。

石のタイルは足元が冷たくて硬いので、敷く場所を決める際にはこの点を考慮する必要があります。南向きの部屋では、石は周囲の温度に順応し、太陽の光で温まりますが、寒くなる可能性のある北向きの部屋では、石の床は理想的な選択肢ではないかもしれません。とはいえ、ラグを敷くことで石の床を柔らかくすることができます。 

China and glass will almost certainly break if dropped on a solid stone floor. Some polished surfaces can be slippery in bathrooms, but there are textured tiles with non-slip finishes. The best way to find out if a floor covering is suitable for your space is to ask your supplier; if your selected tile isn’t appropriate, they will be able to suggest a similar option that is.

石の床タイルは床暖房と互換性がありますか?

Solid stone floor tiles are the perfect partner for underfloor heating because of the ease at which it absorbs and emits heat. This can be especially useful in a bathroom or kitchen. Not only will it feel pleasant under bare feet, but it is also an effective way of reducing the risk of damp because of the constant ambient temperature in the room.

石の床タイルの敷き方

It is possible to tile a floor yourself if you're a keen DIYer with the correct tools, time, patience and you don’t mind making one or two mistakes. For the sake of a weekend’s work, you could use the money 他の場所に設置する場合の設置コストは、他の場所に比べて高くなります。自分で設置することに決めた場合は、事前に下調べをするか、少なくとも専門家に作業を評価してもらってください。

This said, many suppliers recommend professional fitting for natural stone, so if you're not confident in your abilities it may be worth getting the help of a professional if you want the perfect finish – especially if you've spent a lot of money on your natural stone floor tiles. 

Other considerations include whether your joists will take the weight of large tiles or thick flagstones – timber floors may need strengthening. 

天然石の床タイルのメンテナンス方法

Natural floor tiles will need to be sealed to prevent damage, staining, and to avoid repairing stone floors yourself. Your supplier or installer will be able to recommend the most appropriate products to use and should provide you with advice on looking after your chosen material. Once you have the correct product, cleaning stone floor tiles is a simple job.

Using cleaning products that aren’t recommended can leave behind a film, which can attract dirt and may need chemical removal at a later date. Regular sweeping will keep loose dirt away and, if needed, stone can be professionally cleaned and restored.
