Extra-large stoneware slabs for stone-effect tiling for bathrooms

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.
