How much does developer-state apartment finishing in Katowice cost in 2026?

This is one of the first questions that comes up after taking the keys from the developer. And rightly so — a well-calculated budget at the start limits chaos, costly changes and disappointment during the works.

If you want a short answer: in 2026, on the Katowice and Upper Silesia market, a sensible developer-state apartment finishing most often falls in the range of around PLN 1,400 to 3,000+ per m². The lower end applies to a simpler scope and functional standard; the upper grows with material quality, the number of MEP changes, custom built-ins and the level of detail refinement.

In practice, the biggest investor mistake is looking only at the per-square-meter rate. Meanwhile, the final cost depends mainly on what actually has to be built in the apartment: how many bathrooms there are, whether you change the layout of electrical points, whether you plan a custom kitchen and wardrobes, whether you choose simple finishing or a higher standard.

Indicative cost ranges per m² in 2026

Treat the figures below as a reference point before a free quote — not a ready-made price list. This is the Katowice and Silesia market, where the final price depends on scope, building, start date and material quality.

Within these ranges the biggest variables are usually the kitchen, bathroom, amount of joinery built-ins, scope of electrical and plumbing changes — and whether the project is meant to be simply aesthetic and functional, or refined to a premium standard.

What does this mean for a 50 m² and 70 m² apartment?

For the investor, the more important question than the per-meter rate is: how much money do I really need to prepare for the entire apartment. So it’s worth looking at the budget holistically.

• 50 m² apartment: most often around PLN 70,000–95,000 with a simpler standard, around PLN 95,000–130,000 with a higher standard, and clearly more with many built-ins or premium solutions.
• 70 m² apartment: most often around PLN 100,000–135,000 with a sensible standard, around PLN 135,000–180,000 with a higher standard, and above this level with a more individual project.

If a more elaborate kitchen is in the picture, a lot of custom joinery, decorative lighting or a second bathroom, the budget grows very quickly. So always look at the quote through the lens of a specific scope, not just square meters.

What most strongly affects apartment finishing cost?

The final quote isn’t only affected by square meters. Often two apartments of similar size have completely different budgets, because the scope of works and expected standard differ.

• Number and standard of bathrooms: this is one of the most cost-driving zones in the apartment.
• Kitchen and built-in furniture: custom furniture can significantly raise the budget — but it also genuinely affects the interior’s functionality.
• MEP changes: relocating electrical points, plumbing or adding circuits requires time and coordination.
• Finishing materials: large-format tiles, stone, good-quality fittings or premium-class vinyl mean a higher cost — but usually also higher durability.
• Detail and execution precision: drywall built-ins, linear lighting, hidden doors, precise material matching and harder details always require more work.

Where is it not worth saving?

If the budget is tight, look for savings where they don’t affect durability and daily comfort. There are, however, areas where overly aggressive cuts almost always come back later as rework or frustration.

• electrical and plumbing installation,
• waterproofing and bathroom execution,
• quality of floors and doors,
• equipment and fittings in heavily used zones,
• a good functional design, if the apartment should be comfortable for years.

In practice it’s better to limit some decorative elements or break some purchases into stages than to save on things that are then hard to fix without an additional renovation.

Does interior design help keep the budget?

Yes, especially when the design is prepared for real execution capabilities — not just for the visualization effect. A well-thought-out design limits “in-flight” changes, organises the sequence of works, makes shopping easier, and lets you cost the scope better before crews arrive.

If you want to combine concept with execution, also check interior design in Katowice. In practice, combining design and delivery in one team usually reduces the number of costly decisions made under time pressure.

How to approach the quote so you don’t underestimate the budget?

The safest model is to assume two budget levels:

1. a base budget for the scope you want to do right away,
2. a reserve of around 10–15% for changes, corrections and decisions that come up along the way.

This is especially important for apartments handed over by developers, because even with a new unit the list of fixes and refinements after measurements is often longer than the investor assumes at the start.

Why compare offers on more than just the per-meter rate?

A low price per m² may seem attractive, but says nothing about what’s included. One offer may include MEP changes, trade coordination, built-in installation and handovers — another only some basic works. So when comparing quotes, check:

• whether materials are on the contractor’s or investor’s side,
• whether the offer includes full coordination,
• how changes during the works are settled,
• whether the most cost-driving zones — bathroom and kitchen — are included in the quote.

Apartment finishing in Katowice: the local context matters

Katowice and the entire Upper Silesia is a market where, alongside new developer investments, there is also a lot of older construction and investment property. This means very different work scenarios: from simple finishing of a new apartment to more complex modernizations with additional joinery, acoustics, lighting and reorganization of the functional layout.

If you want to see what completed projects look like and what standard is achievable, check Hekabe projects and a sample Ceglana apartment. This is a good reference point before deciding on budget and scope.

This guide mainly covers a developer-state apartment. If you’re considering an older unit, also see what to check before buying an apartment for major renovation and where to start a secondary-market apartment renovation, since the cost and risk range there is usually wider than at developer handover.

Lighting is often a forgotten budget item — suspended ceilings with LED cost PLN 4,000–24,000 per living room and change the perception of the interior.

Frequently asked questions

How much does finishing a 50 m² apartment in Katowice cost?

Most often you need to prepare a budget from a few dozen to over one hundred thousand PLN, depending on the standard, number of MEP changes and whether custom built-ins are part of the scope.
