Modular indoor staircases: Rintal's kit solution

Modular staircases are today one of the most popular solutions for connecting two floors across different domestic settings. Available as ready-to-assemble kits, they combine the design of modern indoor staircases with the practicality of a component-based system, accessible in both lead times and cost. In this guide we look at what modular staircase kits are, what advantages they offer compared with other solutions, and the Rintal models designed to furnish every home with style, from open stairs to space-saving staircases and indoor spiral staircases.

What modular staircase kits are

A modular staircase kit is a staircase made up of component parts that are assembled on site during installation. The box contains the structure, treads, railing and handrail, which come together on location to form the finished staircase.

Unlike pre-built staircases, modular staircases are designed around a standard system of components and adjustments that allows the same staircase to be adapted to different settings. The base kit can also be tailored by adding one of the many available accessories, such as an additional step to reach greater heights, the balustrade, the inner railing or the lighting kit.

This is what makes it possible to talk about modern indoor staircases that are accessible, quick to install and refined in their design.

Why choose a modular indoor staircase

Modular staircase kits meet the typical needs of those renovating or furnishing a home:

• Quick and straightforward design: every staircase can be configured using a proprietary software tool that builds the project in real time based on the space available.
• Tailored solutions: each staircase can be adapted by choosing among the many accessories available for each model.
• Fast delivery: thanks to extremely short production times.
• Easy transport: a complete staircase, including structure, treads and railing, fits into a single box.
• Adaptable to any space: the system for adjusting the distance between the steps in height (rise) and depth (going) makes it possible to fit the staircase to the space available and to strike the right balance between climbing comfort and footprint.
• Easy assembly: a single DIY enthusiast can install the staircase by simply following the instructions and the assembly videos provided.

The Rintal range

Rintal offers a broad range of modular indoor staircases, all built on the same kit logic but available in different models and typologies. What changes from one model to another is the staircase typology: open, space-saving or spiral. The choice depends on the space available, the desired aesthetic and the type of passage to be created between the floors.

Modular open staircases

Open staircases are characterised by straight treads supported by a modular steel structure. They are the most common typology and work well in settings where there is enough room to develop the flight at a comfortable incline. Available configurations are straight, with a 90° turn or with two turns.

Rintal offers two open staircase models:

• Composity: the open staircase that combines the look of bespoke stairs with the advantages of a modular system. The steel structure supports beech wood treads, available in widths of 74, 84 or 94 cm. Find out more on the dedicated page.
• Knock: designed by Giugiaro Architettura, this is a contemporary staircase with a solid steel structure and beech wood treads. A distinctive feature is the option to integrate an LED lighting system between the treads. Discover more on the dedicated page.

Modular space-saving staircases

When the space available is limited, the space-saving staircase is the most effective answer. They feature shaped, alternating treads that allow a steeper pitch than a traditional open staircase, reducing the footprint without overly compromising climbing comfort.

In the Rintal range, the space-saving staircase is represented by two models:

• Small: the most affordable space-saving staircase in the range, designed to make the most of the space available with a practical, safe solution. It features shaped, alternating pine treads, a modular steel structure and straight, one-turn or two-turn configurations via landings. Find out more on the dedicated page.
• Mini: the modular staircase designed for mezzanines, lofts and floor-to-floor connections in compact areas. It features beech treads with an alternating shape, a modular steel structure, and straight, one-turn or two-turn configurations via landings. Discover more on the dedicated page.

Modular indoor spiral staircases

The spiral staircase develops vertically, rotating around a central pole with treads arranged in a circle. It is a solution that concentrates the footprint within a small area and is often chosen both for space reasons and for its visual impact.

Rintal offers three indoor spiral staircase models:

• Phola: the spiral staircase that combines the warmth of beech wood treads with the steel structure. It is available in different diameters and finishes, suiting residential settings that differ in style and dimensions. Find out more on the dedicated page.
• Hoop: the spiral staircase with a contemporary design, featuring pine treads and a steel structure, available in different diameters to fit both compact rooms and larger spaces. Discover more about Hoop.
• Gamia Metal: the spiral staircase made entirely of steel, available in several diameters and in a broad range of colours, well suited to projects with an industrial or contemporary character. Find out more on the dedicated page.

For those looking for an outdoor spiral staircase, Rintal offers the Exterior Zink model, in galvanised and painted steel engineered to withstand the elements.

Design, finishes and variety of styles

The final look of a staircase depends on the colour combinations chosen for treads, structure and railing. For models with wooden treads, eight finishes are available, from Natural to Wengé, through to Whitewashed and White Lacquered. For the steel parts, the options include White, Silver Grey and Anthracite Grey, depending on the model.

The freedom to combine finishes makes it possible to adapt every staircase to its setting: dark tones for rooms with a material character, light finishes for bright, contemporary projects, sharp contrasts for bolder solutions.

Frequently asked questions

What does modular staircase kit mean? A modular staircase kit is a staircase made up of prefabricated elements (structure, treads, railing, handrail) that arrive in a box and are assembled during installation. The system allows the rise and going to be adjusted to the available floor-to-floor height, fitting the staircase to the space.

Which types of modular indoor staircases does Rintal offer? The Rintal range covers three indoor staircase typologies: open staircases (Composity, Knock), space-saving staircases (Mini, Small) and spiral staircases (Phola, Hoop, Gamia Metal).

Can a Rintal staircase be installed independently? Yes, the assembly is designed so that a DIY enthusiast can complete it by carefully following the installation instructions.

Which modular staircase should I choose if I have little space? When floor space is limited, the most suitable options are space-saving staircases, which thanks to their alternating treads reduce the footprint while preserving climbing comfort, or spiral staircases such as Hoop, Phola or Gamia Metal, which concentrate the footprint around a central pole.

Are Rintal modular staircases available in different finishes? Yes. Depending on the model, several wood finishes are available for the treads (from Natural to Wengé, through to Whitewashed and White Lacquered) and several steel colours for the structure and railing (White, Silver Grey, Anthracite Grey). The combinations make it possible to adapt the staircase to different interior styles.

Conclusions

Modular staircase kits are today one of the most balanced solutions for connecting two floors at home: they bring together the advantages of series production (contained costs, fast lead times, consistent quality) and the flexibility to adapt to each individual project.

The Rintal range applies this logic to three indoor staircase typologies, with models designed to cover a wide range of needs, in terms of both space and style. Selected materials, Italian design and an assembly system engineered to be straightforward make these staircases a sound choice both for those designing a new home and for those carrying out a renovation.
