How to Cut Interior Costs for a 33㎡ Studio Apartment

A full interior renovation of a 33㎡ (10-pyeong) studio typically costs 8–15 million won, but knowing that nearly half of that goes to labor and demolition fees can save you over 3 million won.

First, Understand the Cost Structure of Studio Renovation

Market Rates for 33㎡ Units and Why Costs Are Rising

As of 2024, interior costs for a 33㎡ studio fall into three tiers depending on the scope of work. A full renovation—complete demolition and re-installation—runs 8–15 million won. Partial renovation, such as repainting and replacing some furniture, costs 2–5 million won. A self-done, furniture-focused makeover comes in at 1–3 million won.

The reasons behind rising costs are clear. Prices for lumber and steel have climbed since the Russia-Ukraine war, and a shortage of construction labor has driven carpentry and electrical wages up 5–10% per year. In particular, small-scale projects like studio renovations often carry a minimum charge of 1.5 million won or more due to call-out and management fees, even when the actual work volume is small. Reducing the scope of work itself is therefore the starting point for savings.

Half the Money Goes to Labor—That's Where the Savings Are

Looking at the cost breakdown, labor accounts for the largest share at 40–50% of the total, followed by materials at 30–40%, demolition at 10–20%, and design and management fees at 10–15%. Labor is also where the greatest savings potential lies. Doing demolition yourself or narrowing the scope of work cuts demolition costs, while communicating directly with contractors instead of using a designer reduces design and management fees. Buying materials yourself can lower material costs as well.

Interior spending tends to concentrate on two or three key areas—such as the bed, sofa, or kitchen—rather than being spread evenly across the space. The same principle applies to savings. Focusing renovation on the most-used areas and handling the rest with paint and furniture placement significantly boosts satisfaction relative to budget.

Item-by-Item Savings Strategies and the Best Choice for Each Budget

Leave the Structure Alone—Change Only the Surfaces

The most important rule is to leave electrical, plumbing, and structural elements as they are. Moving water and electrical lines can add millions of won to the bill, and experts point out that "messing with electrical or plumbing to save money is the worst mistake." The most economical approach is to keep the immovable structure intact and transform the space with furniture, lighting, and fabrics.

For surface finishes, low-cost alternatives are clear. Instead of hardwood flooring, overlaying decorative tiles at 30,000–50,000 won per 3.3㎡ saves 50–70%, and if existing flooring is in good condition, an overlay alone is sufficient. Swapping premium silk wallpaper for laminate wallpaper with an accent wall saves 30–50%. Using modular or system furniture instead of custom pieces saves 40–60%, and replacing only the countertop or doors instead of the entire kitchen sink unit saves 50–70%.

A 2 Million Won Budget Means Partial Renovation; 1 Million Won Means DIY

With a budget of 2–5 million won, partial renovation—repainting, partial floor replacement, and new lighting and curtains—offers the best value. One real example involved a 33㎡ studio refreshed for exactly 2 million won: 400,000 won for painting, 400,000 won for decorative tiles, 200,000 won for lighting, 400,000 won for a bed, 300,000 won for storage, 200,000 won for accessories, and 100,000 won for cable management. Since minimum service charges are an obstacle, bundling multiple items with a single contractor helps avoid duplicate call-out and management fees.

With a budget around 1 million won, DIY is the way to go. Painting over wallpaper, applying DIY film, assembling furniture, and installing lighting are all manageable on your own. However, electrical, plumbing, tile, and bathroom work should always be left to professionals, since defects raise liability issues. It's safer to exclude these from your cost-cutting plans. Buying materials yourself through online channels like Today's House and paying only for labor saves an additional 10–30%, while discontinued or clearance materials can be 30–70% cheaper.

Comparing Quotes and Contracting: The Final Step to Avoid Regret

Ask for Itemized Unit Prices

Even for identical work, quotes can differ by hundreds of thousands of won between contractors. Get quotes from at least three companies for the same items and specifications to make comparison possible. Beware of quotes that list only a lump sum. Breaking costs down into demolition, materials, and labor reveals inflated charges, and you must confirm before signing whether demolition and haul-away fees are billed separately.

Contract terms matter too. Keep the down payment within 10–30% of the total, pay the balance only after confirming completion, and specify a 6-month to 1-year warranty period in the contract. Avoid contractors demanding 100% payment upfront. During the year-end-to-February moving peak season, labor costs rise and schedules fill up, so getting quotes and booking work in the off-season gives you more negotiating leverage.

Tenants Should Check the Restoration Clause First

If you're renting, the landlord's prior consent is essential before repainting or replacing flooring. If you're obligated to restore the unit to its original condition, you won't recover your renovation investment, so weigh move-out costs and rent negotiation leverage together. Lighting and outlet placement should be decided only after finalizing furniture layout—doing it the other way around incurs rework costs. It's also worth noting the most common regrets in consumer reviews: keeping dark package lighting as-is, sink film peeling within a year or two, and signing a contract without comparing quotes.
