The staircase takes more daily foot traffic, scuffs and knocks than almost any other surface in a home, and it is often the first thing a guest notices in the hall. With the wrong cladding it wears quickly; with uneven steps or slippery edges it becomes a hazard. This guide compares marble, porcelain and granite for stairs and explains how to renovate a staircase in the right order.
Signs your staircase needs work
Not every problem means replacing all the cladding, but these are common triggers:
- Chipped or broken nosings, the front edge of each step that takes the impacts.
- A hollow sound when you tap a tread, usually meaning the adhesive did not fill the space underneath.
- Visible wear or dullness down the middle where people walk.
- Uneven riser heights, which make people trip even when the difference is hard to see.
- Cracks in the concrete under the cladding or where the stair meets the wall.
- A dated look as part of a wider home renovation.
Marble: natural luxury, with conditions
Marble is a natural stone, and every slab has its own veining. That is why many owners choose it for the main stair in the hall.
- Strengths: a premium natural look; treads can be cut from a single piece with a bevelled or rounded nosing; it can be reground and repolished years later.
- Watch for: it is softer than granite and scratches over time; some types are etched by acids such as juice or harsh cleaners; a high polish can be slippery; it needs a sealer and periodic maintenance.
Porcelain: consistency and easy care
Porcelain is a manufactured tile with very low water absorption, now made in convincing marble and stone looks.
- Strengths: consistent colour and pattern that matches the hall floor easily; resists staining without regular sealing; available in matt and anti-slip finishes; large formats mean fewer joints.
- Watch for: the nosing is the weak point. On surface-printed porcelain a cut edge shows the body colour, so purpose-made step pieces, a metal nosing profile or through-body porcelain are used. It cannot be reground like stone, and it demands a careful installer because edge errors are obvious.
Granite: hard-wearing for heavy use
Granite is much harder than marble and is common on external stairs and in commercial buildings.
- Strengths: high resistance to scratching and wear; generally less porous, so it stains less; well suited to entrances and outdoor steps, especially with a flamed or textured finish.
- Watch for: a narrower colour range and a more formal look; harder to cut and shape; polished granite is slippery too, so the finish matters.
Side-by-side comparison
| Criterion | Marble | Porcelain | Granite |
|---|---|---|---|
| Look | Natural, unique veining | Uniform, stone-look options | Natural, fewer colours |
| Scratch resistance | Medium | Good | Very high |
| Stain resistance | Needs sealing | High | Good |
| Slip resistance | Poor if polished | Good with the right finish | Poor if polished, good if textured |
| Maintenance | Periodic regrinding and sealing | Simple | Simple |
| Nosing | One piece, shaped edge | Step pieces or profile needed | One piece, shaped edge |
| Relative cost | Medium to higher, by type and source | Lower to medium | Medium to higher |
Relative cost is only a guide: premium porcelain can cost more than some local marble. More important than the material is the installation, because the best stone fails on a badly prepared stair.
Match the material to the stair
- Main stair in the hall: looks matter, so marble or marble-look porcelain are popular, provided slip resistance is dealt with.
- Secondary stairs to the roof or service annex: durability and easy cleaning come first, and matt porcelain is a practical choice.
- External and entrance steps: sun, dust and water favour textured granite or an outdoor-rated anti-slip porcelain.
- Commercial buildings: constant heavy traffic puts hardness and wear resistance ahead of everything else.
Renovating a staircase step by step
- Remove the old cladding and inspect the structure. Take it off carefully, then check the concrete for cracks or exposed reinforcement and repair any damage first, as described in our guide to renovating an old villa.
- Correct levels and heights. This is the most important step and the most often skipped. Risers must be equal in height and treads equal in depth, because people fall into the rhythm of a stair after the first two steps. The new cladding thickness plus bedding is calculated, and the first and last steps are matched to the floor levels.
- Bed every piece fully. Treads and risers go onto adhesive or mortar that covers the whole back of the piece. Voids cause the hollow sound and, eventually, broken nosings. External steps get a very slight fall outward to shed water.
- Finish the nosing. Stone nosings are shaped from the tread itself; porcelain uses step pieces or a profile. Add anti-slip grooves if the surface is polished.
- Grout, clean and seal. Joints are filled with a matching grout, and natural stone is sealed against staining.
- Handrail and lighting. A firm handrail and good lighting are safety items, not decoration. Run cables for any wall lights before cladding.
Skipping any of these steps causes the most common stair defects, many of which mirror general tiling errors; see floor levelling and tiling mistakes.
A before-and-after from our work
Our projects page includes before and after photos of a staircase from our work. What makes the finished result is not the stone alone, but the levels, nosings and joints that were set right first.
How Marafi renovates stairs
We start with a site visit to inspect the stair and its structure, then send a transparent itemised proposal that states the proposed material and installation method. We repair concrete damage before cladding, set step heights with engineering precision and use approved adhesives, with technicians, supervisors and engineers on the job, the highest safety standards and photo updates at each stage. See Renovation & Rehabilitation, and if the stair is part of a whole-house fit-out, Interior Finishing and Floor Levelling & Tiling. Our way of working is on How we build.
Before you choose
- Consider who uses the stairs and how heavily.
- Marble for a natural look if you accept upkeep; porcelain for consistency and easy care; granite for heavy use and outdoors.
- Ask how slip resistance and nosings will be handled.
- Make sure the structure is checked and step heights corrected first.
- Insist on full bedding with no voids.

Frequently asked questions
Is marble or porcelain better for stairs?
Marble has a natural, premium look but is softer and needs more care. Porcelain is more uniform and easier to maintain. The right choice depends on how heavily the stairs are used, the look you want and how much upkeep you accept.
Are polished marble stairs slippery?
A high-polish finish can be slippery, especially when wet or in socks. A honed finish on the treads or anti-slip grooves near the nosing reduce the risk, along with good stair lighting.
Can old stairs be reclad without demolishing them?
Usually yes, if the concrete stair structure is sound. The old cladding is removed, the structure is checked and step heights are corrected before the new cladding goes on.
How do I find out what my staircase renovation will cost?
It depends on the material and its source, the number and shape of the steps, and the condition of the structure underneath. A site visit followed by an itemised proposal is the reliable way.
