Kit Details

These stairs stand out with a modern minimalist design that fits both loft-style and classic interiors. Metal balusters — slim rectangular tubes sized 30×30 mm or round tubes with a diameter of 27 mm — create a light and elegant look. Wooden stair treads contrast beautifully with the metal elements, forming a stylish interior accent.

The design is supported by thoughtful engineering: the stairs are suspended by metal balusters attached to a metal profile that is fixed to the ceiling in advance. This profile can be easily hidden in a drywall or stretch ceiling, making the staircase look even lighter.

On the other side, each stair tread is securely fixed to the wall with a metal rod. This fixing provides strength and stability, allowing the wall to carry the structural load reliably. Thanks to the tight fit of the tread against the wall, the metal elements remain almost invisible, preserving the clean look of the interior.

The kit includes all the necessary components for simple installation, while support from our specialist helps make the installation process easier. K3 Craft stairs change the way people approach staircase installation, making it possible for everyone to have stylish stairs that fit naturally into any interior.

How It Works?

Price Estimate

We calculate an estimated price based on the measurements you provide.

During your first conversation with us, we will calculate an estimated staircase price for you directly during the call. To do this, we only need to know the staircase model you have chosen and a few basic measurements:

  • the height from the finished floor of the first floor to the finished floor of the second floor;
  • the length of the opening;
  • the width of the opening;
  • the thickness of the floor slab between floors.

*The measurements may be approximate.

With this information, we calculate not only the price and number of parts, but also the best step height so that the stairs are comfortable to use.

Are self-installation stairs right for you?

Floor Slab / Ceiling Structure

For self-installation stairs, the embedded beam must be securely fixed to the ceiling, or embedded support strips must be fixed to the side of the floor opening.

Wall

To fix the stair treads into the wall, you need a concrete or brick wall at least 20 cm thick.

Tools

You will need a rotary hammer drill. We provide the fastening hardware and installation instructions.

FAQ Most common questions

Can I buy in installments?

You can purchase the stairs in installments through PrivatBank or Monobank. We work with official installment programs that allow you to split the payment into convenient monthly payments without paying the full amount at once. You can ask our manager for the detailed terms when placing your order and choose the most comfortable option for you.

What is the production lead time?

The production lead time usually depends on the type of stairs and the current workload of our manufacturing facility. For standard modular solutions, it is usually 1–4 weeks. For more complex custom structures, the lead time may be longer, because the individual design, non-standard materials, and additional elements must be taken into account. We provide the exact timeframe after the model, materials, and all required measurements are confirmed.

What warranty do you provide?

We provide a warranty of up to 5 years with the possibility of replacing or repairing individual parts if manufacturing or structural defects are found. You also have an installation support guarantee: part of the payment is made only after the stairs have been installed and you have checked the quality of the structure. We stay in touch and are ready to help with questions about use and care.

Do you deliver internationally?

Yes, we officially export our products from Ukraine to other countries. We pack the components so they can safely withstand transportation, and we also provide instructions and the necessary documents. You can ask our manager about delivery to your country, the estimated timeframe, and approximate transportation cost during the consultation.

How do I choose a color?

You can choose any color from our catalog of wood tones and finishes, and we will send you samples so you can see them in your interior. We can also match the closest possible color based on a sample you provide, such as a piece of flooring, a door, or furniture. Our goal is for the stairs to fit naturally into the space rather than stand out from the overall style.

What can workers use during renovation?

If you need a temporary solution during renovation, we can offer affordable temporary stairs for the construction period. After the renovation is complete, you can return them with partial reimbursement or keep them for practical use. This helps keep the main staircase in perfect condition until all “dirty” construction work is finished.

How much do the stairs cost?

For the most common ceiling height of up to 2700 mm, the approximate cost of stairs without second-floor railings is: bolt-supported stairs — $1,361, L-shaped stairs — $1,606, and metal-frame modular stairs — $2,091. The exact price depends on the configuration, tread materials, type of handrails, and additional elements. For a more accurate estimate, we ask you to provide the basic measurements and the model you have chosen.

How do I install the stairs?

For modular stair installation, we provide templates made according to your specific staircase design, as well as detailed installation instructions. You receive a fastening kit, a diagram, and remote support from our specialist, who can guide you through each stage. Thanks to this, most customers successfully install the stairs themselves without hiring expensive installation crews.

How strong are these stairs?

Fixing the structure to the walls and floor slab, together with the use of high-quality metal elements, provides strong structural performance. Properly installed modular stairs are comparable in reliability to traditional fixed staircases. Each connection point is designed to withstand everyday loads, and all materials go through quality control during production.

I want measurements and a design.

To help you avoid unnecessary costs for an expensive on-site specialist, we created a remote support format. During a video call or phone call, our specialist will help you take all the necessary measurements correctly, explain what to pay attention to, and identify which dimensions are critical for safe and comfortable stairs. After that, we prepare the staircase design and confirm it with you before starting production.

Why don’t you install your stairs?

The concept of K3 Craft modular stairs combines modern style with an affordable price. One reason we can keep the price attractive is that customers can install the stairs themselves using our instructions and support. This means you do not overpay for a large installation crew, while still receiving a reliable structure assembled according to a clear design.

I don’t have tools.

Modular stair installation requires a basic set of tools that many households already have: a drill, level, set of wrenches, and screwdrivers. No specialized or industrial equipment is required. We provide a list of tools for your specific project in advance, so you can prepare everything beforehand or purchase any missing items if needed.
