Choosing stone, porcelain and marble surfaces for London interiors

When should I specify natural marble or stone?

Natural marble and stone are the right choice when the scheme wants unrepeatable veining, depth of tone and the quality of a genuinely quarried surface — feature walls, statement islands, bathroom vanities, entrance floors, fireplace surrounds. The trade-off is variation: no two slabs match exactly, so the designer selects the specific slabs at the yard or via a slab-selection service. Natural stone also requires informed detailing — sealed installations, correct edge profiles, and a maintenance regime the client is briefed on.

When does large-format porcelain make more sense?

Large-format porcelain slabs are the practical answer when the scheme needs a stone-like appearance with predictable performance — very large floor fields, wall claddings that repeat between rooms, wet areas where absorption matters, or bathrooms where a continuous look is more important than natural variation. Porcelain is lighter than natural stone (useful in apartment buildings), does not need sealing, and is available in slab formats that reduce the number of joints. It is also the more predictable specification for developer projects where units need to match.

Where do engineered surfaces fit?

Engineered surfaces sit between the two: designed patterns with engineered composition, sold in slab. They are commonly specified for kitchen worktops, high-use vanities and commercial settings where consistency and resistance matter more than natural variation. As with porcelain, you are working with a reproducible pattern rather than a unique block.

How do trade professionals view Florim, Cosentino and Margraf at Faura?

At Faura, Margraf is reviewed as the natural stone reference — designers look at full slab boards and, for statement pieces, arrange slab selection. Florim is reviewed for large-format porcelain — walls, floors, bathrooms and any project that wants a stone-adjacent look in porcelain performance. Cosentino is the engineered-surface reference for worktops, vanities and high-use elements. The three brands are held side by side, so the choice between them can be made in person, against physical slabs, in the room rather than on a screen.

How do I run a surfaces appointment?

1. Send the plan and the room-by-room brief in advance — which walls, floors, worktops and vanities are in scope.
2. Bring a moodboard or reference images so the host can pull comparable slabs from each brand.
3. Review Margraf natural stone and Florim porcelain against each other for statement surfaces; review Cosentino for worktops and vanities.
4. Take cuttings for client presentation and note the finish (polished, honed, brushed) against each reference.
5. Ask about installation — Faura can introduce vetted tiling contractors for stone and porcelain installation so the surface is fitted by a specialist.

What about the rest of the fit-out?

Surfaces rarely travel alone: the same appointment usually touches bathrooms, brassware, lighting and paints. For how Faura assembles a full fit-out around a surfaces selection, see full fit-out sourcing in London and the finishes and materials landing page.

To review Florim, Cosentino and Margraf against a live London scheme at Faura's Westminster showroom, book a private appointment — the team will pull the relevant slabs and finish boards in advance.
