Stone-effect bathrooms, the trend that is driving contemporary design

Nowadays, a bathroom is perceived as a place for pampering and me-time and in line with this, the tiling used is a vital factor to create the perfect conditions for unwinding. The 2025-2026 trends have shown  a decisive return to the natural-looking textures with sensory appeal of products inspired by materials like stone, sand, and travertine.

Next-generation ceramic surfaces offer unique sensory experiences  through natural colours and rich texturing that interact with light, taking the concept of bathroom tiling to a new level.

Stone-effect porcelain tiles this kind of porcelain is a durable, sustainable material  that is produced using technologies that reduce CO₂ emissions and optimise consumption of resources resulting in highly energy-efficient low-impact processes.

A wide assortment of shades, finishes, and sizes allow users to create coordinated, stylish, and functional spaces, where every detail works together to form a sense of  harmony and realness.

What is the best material for a stone-effect bathroom?

When it comes to designing a stone-effect bathroom, the question we get asked the most is “Which are better for a bathroom, natural stone tiles or porcelain stoneware tiles?”

Well, both materials offer their own advantages:

• Real natural stone: is beautiful and every product is entirely unique, but it also requires constant care and specific treatment to protect it from dampness.
• Stone-effect porcelain tiles: offer a faithful reproduction of stone tiles, in terms of looks, but they also provide a compact, waterproof body with antibacterial properties. They are scratch-resistant and unaffected by limescale and mould, and have much lower maintenance costs.

That is why stoneware is  held to be the best material for a stone-effect bathroom, as it is ideal for tiling walls and walk-in showers, as well as  coordinated furniture.

Extra-large ceramic slabs for high-impact bathroom designs

The introduction of extra-large ceramic slabs has revolutionised the way we conceive ideas for bathroom tiling. Optimum Surfaces has developed an exclusive 1840×3300 mm slab (the largest available on the market) to offer stylish, seamless surfaces.

This distinctive feature minimises joints to create fluid surfacing for bright, high-impact designs, bringing a sense of spaciousness to even the smallest of bathrooms.

Stoneware bathroom tiling for excellent damp resistance

Dampness is one of the main challenges that any bathroom tiling has to  stand up to and stone-effect porcelain is the ideal, most reliable material for this kind of setting. It is waterproof and can withstand build-ups of mould and limescale, and  it is durable.

Optimum extra-large stone-effect porcelain slabs are unaffected by exposure to water, steam, and different temperatures, making them long-lasting and easy to clean.

Looking after your porcelain stoneware is pretty straightforward. For daily cleaning, simply use neutral detergents and a soft cloth to keep it shiny.

Sustainability and technology: two core assets for Optimum

Optimum has chosen to build its production identity around one key concept: sustainable efficiency. This means that every stage of the production cycle is designed to reduce environmental impact, from the procurement of raw materials to the manufacture of oversized slabs only.

The use of natural raw materials and the decision not to quarry to produce the white marble-effect slabs make Optimum stoneware an environmentally responsible alternative to conventional stone materials.

Responsible production, with an eye on the future

Our latest-generation machinery is equipped with systems to recover hot air from spray dryers, dryers, and kilns, reducing the need for fossil fuels. A high-performance CHP plant enables us to self-produce 100% of the electricity we need for production. This guarantees returns of over 80% and an estimated reduction in CO₂ emissions of over 1,000 tonnes per year.

Not only that, the main kiln is already designed to be powered by green hydrogen alongside natural gas: a forward-thinking solution designed with industrial decarbonisation in mind.

The decision to offer just one large size (1840×3300 mm) cuts down processing waste significantly, while also maximising efficiency and ensuring very little is thrown away.

Performance that’s designed to last

Optimum does more than reduce environmental impact: each slab is designed to last by withstanding the stresses of daily use, especially in settings like the kitchen. Thanks to the exceptional features of porcelain stoneware, Optimum slabs are extremely compact, non-absorbent, and stable, even in high-wear conditions.

The slabs offer protection against scratches, impacts, heat, and chemicals. This makes them perfect not only for walls, but also for porcelain stoneware kitchen tops, worktops, islands, and backsplashes that are exposed to mechanical and thermal stress.
