Interior Material Grades in Korea: Flooring, Wallpaper, Tile, Windows
Compare basic, standard and premium flooring, wallpaper, tile, windows and doors: KRW price ranges, upgrade costs, picks by situation, upkeep.
When you open a Korean interior quote, it lists materials such as "laminated wood floor", "silk wallpaper" or "system windows". What is hard to tell is how those materials really differ and how much more a one-step upgrade costs. This guide compares flooring, wallpaper, tile, paint, windows, doors, lighting, bathrooms and kitchens using the three grades (basic, standard, premium) in the K Real Estate material price table, and explains where to spend and where to save depending on your situation. Prices are estimates of average Seoul-area market rates as of October 2026, so brands and site conditions will move them.
What basic, standard and premium really mean
- Basic means overlaying or replacing with budget materials: a PVC vinyl floor sheet, paper wallpaper, or a film refresh on existing doors. It suits cases where the goal is simply a clean, usable home.
- Standard is the most common choice in a Korean apartment full remodel: laminated wood flooring (called gangmaru), vinyl "silk" wallpaper, porcelain tile and branded double-glazed windows. It balances durability and price.
- Premium covers solid wood flooring, eco-friendly or imported wallpaper, large imported porcelain and high-insulation system windows. You pay more for texture, performance and design, and upkeep usually becomes more demanding.
When you move up a grade, the increase comes mainly from material cost. For flooring, material runs KRW 8,000–12,000 per ㎡ at basic grade and KRW 55,000–85,000 at premium, a gap of five to seven times, while labor goes from KRW 5,000–7,000 to KRW 15,000–22,000, about three times. That is why the grade you pick for large-area items such as floors, wallpaper and windows moves the total the most.
Price ranges per material (material plus labor)
The table adds material and labor together. It excludes site overhead (7%) and VAT (10%), which together add roughly 17.7%.

Flooring: choose standard or above, because you walk on it every day
- PVC sheet is waterproof and cheap, but it dents under heavy furniture and scratches easily. It fits a quick refresh before renting or selling.
- Laminated wood (gangmaru) has a surface layer bonded to a board base. It handles floor heating (ondol) and humidity fairly well, so it is the most used floor in apartments. Wipe spills quickly and put pads under chair legs.
- Solid wood feels best but expands and shrinks with humidity, so you must manage indoor moisture, and a sudden jump in heating can open gaps. Labor is also the highest.
Wallpaper and paint: easy to redo, so starting basic is fine
- Paper wallpaper is the cheapest and quickest to hang, but stains do not wipe off. Avoid it if you worry about children's drawings or kitchen splashes.
- Silk wallpaper has a coated surface that you can wipe with a dry cloth, and its seams are less visible. It is the safe standard choice.
- Eco-friendly or imported wallpaper emits fewer harmful substances and offers more designs. It is worth it if someone in the family has allergies or asthma. Check the formaldehyde emission grade (such as E0 or E1) and the test report.
- Paint: on walls that suffer condensation and mold, such as the balcony, elastic coating resists cracks and mold better than ordinary water-based paint.
Tile, windows, doors and lighting: things you do once
- Tile: porcelain absorbs little water and is hard, which suits entries and balconies. Large porcelain has fewer joints and looks premium, but it is harder to install and costs more.
- Windows affect insulation, noise and condensation directly and take the biggest share of the total. Branded double glazing is the standard way to cut heating bills and noise. System windows perform best, so weigh the benefit against the cost.
- Doors: a film refresh is the cheapest when the doors are sound. ABS doors resist moisture and are light, and are used when frames are replaced too. Hidden doors are about design and cost the most.
- Lighting: basic LED replacement gives enough brightness. Indirect and recessed line lights change the mood but come with ceiling work.
What a one-step change costs (84㎡ unit)
The estimates use about 77㎡ of flooring (floor area × 0.92), about 252㎡ of wallpaper (floor area × 3.0) and windows priced on 84㎡. They include overhead and VAT and are approximate.
| Change | Difference |
|---|---|
| Flooring: standard to premium (solid wood) | + KRW 3.73M–6.10M |
| Flooring: standard to basic (PVC) | save KRW 1.46M–1.91M |
| Wallpaper: standard to premium | + KRW 1.78M–3.26M |
| Wallpaper: standard to basic (paper) | save KRW 1.33M–1.78M |
| Windows: standard to basic | save KRW 6.92M–9.39M |
| Windows: standard to premium | + KRW 12.36M–16.31M |
Dropping wallpaper to paper saves KRW 1.33M–1.78M, while dropping windows one grade saves KRW 6.92M–9.39M. So when deciding where to downgrade, start with the large-ticket items (windows, bathrooms, kitchen) and keep standard for the floors and walls you see and touch daily. See the 84㎡ remodeling cost guide for full totals, and change the grade for each trade in the remodeling estimator to test your own case.
Recommended mixes by situation
| Situation | Recommendation |
|---|---|
| Short-term refresh before renting out or selling | Silk wallpaper, laminated wood or PVC floor, basic lighting. Skip big work |
| Living there for 10 years or more | Standard or above for windows and bathroom waterproofing; standard floors and wallpaper |
| Young children or pets | Wipeable silk wallpaper, scratch-resistant laminated wood plus mats |
| Draughty home with condensation | Standard or better windows plus elastic coating on the balcony |
| Allergies or sensitivity to new-home smells | Eco wallpaper and paint, check emission grades, ventilate well after work |
| Tight budget | Judge windows and bathrooms by condition; improve the feel with wallpaper, floors and lighting |
Upkeep and common mistakes
- PVC sheet: use furniture cups under heavy items and avoid hot pans. Repair tears early.
- Laminated wood: standing water seeps into joints and lifts the boards. Use a well-wrung cloth and check for condensation near the balcony.
- Solid wood: avoid abrupt heating in midwinter and humidity in the rainy season, and keep indoor humidity steady.
- Wallpaper: mold returns unless you fix the cause of condensation. Look at insulation, ventilation and windows together.
- Tile grout and silicone: replace bathroom silicone when mold appears and inspect it every few years.
- Windows: clean the tracks and check the rubber gaskets and locks.
Three mistakes come up often. First, the quote says only "premium materials" without brand, model and size. Second, choosing from photos without a sample, so color and texture differ. Third, a verbal "equivalent substitute" during work that never gets settled in price. Attach material specifications to the contract and put every change in writing. Our interior contract checklist covers this in detail, and materials matching can help you find suppliers.

Frequently asked questions
Q. Is laminated wood or PVC sheet better for a Korean apartment floor?
In the price table, PVC sheet is about KRW 13,000–19,000 per ㎡ and laminated wood about KRW 29,000–40,000. For long-term living laminated wood gives better texture and durability, while PVC is reasonable for short rentals or a pre-sale refresh.
Q. Where should I spend more on interior grades?
Prioritize floors and wallpaper that you touch and see daily, plus windows and bathroom waterproofing that are hard to fix later. Lighting and doors are easy to change later, so basic grade is fine to start.
Q. How much can I save by lowering the grade?
For an 84㎡ unit, switching wallpaper from silk to paper saves about KRW 1.33M–1.78M including VAT, and switching windows from standard to basic saves about KRW 6.92M–9.39M. The bigger the area and unit price, the bigger the saving.
