The development of a blue color on tiles occurs either through intentional manufacturing using cobalt oxide glazes, or unintentionally via chemical staining in wet environments like showers.
Shower tiles turning blue or blue-green is usually caused by copper pipes corroding due to acidic water (low pH). The water leaves behind copper deposits, which oxidize and stain tiles and grout. Other causes include using products with blue beads, or moisture trapped behind tiles causing darkening of the tile body.
The colour blue gained special significance in the history of Chinese ceramics during the Tang dynasty (618-907). The distinctive colour in blue-glazed pottery and porcelain comes from cobalt ores imported from Persia, which were a scarce ingredient at the time and used in only limited quantities.
Efflorescence, dirt, dust or grime can build up on a tile's surface however and cause them to appear discoloured or even faded. In these cases, taking the proper steps to thoroughly clean your porcelain tiles will bring them back to their original state!
Use a 3% hydrogen peroxide to remove stains from ceramic and porcelain. For gentle surface cleaning you can make a paste with one part peroxide and two parts baking soda. Apply the paste and let it sit for about 30 minutes before scrubbing and rinsing. You can also pour peroxide directly on stubborn stains.
To reverse blue dye that has bled onto white material, do not put the item in the dryer, as heat sets the dye. Immediately rewash the item with a color-safe oxygen bleach or a dedicated color remover to break down and lift the unwanted pigment.
No, blue stain (or sap stain) is not mold. While both are types of fungi, blue stain penetrates deep into the wood fibers, whereas mold only grows on the surface.
Make a paste using baking soda and a small amount of water. Apply it to the hard water stains and let it sit for 10 to 15 minutes so the baking soda can break down the mineral buildup. Scrub gently with a soft sponge or cloth, then rinse thoroughly with warm water.
When selecting bathroom tiles, it is best to avoid stark white (which shows every hair or stray drop of water), cool grays (which can make spaces feel clinical and dated), and pure black. Highly saturated, bright colors should also be avoided, as they cast reflections that can be unflattering in the mirror.
No, porcelain paving does not fade over time when exposed to sunlight. Porcelain tiles are made with durable pigments that are fired at high temperatures during manufacturing, which makes the colour stable and resistant to UV rays.
Chinese blue and white porcelain was once-fired: after the porcelain body was dried, it was decorated with refined cobalt-blue pigment mixed with water and applied using a brush. It was then coated with a clear glaze and fired at a high temperature.
In nature, true blue rarely exists as a chemical pigment. Instead, the color is generated by microscopic physical structures that scatter light, or by complex chemical compounds like copper and indigo. Historically, humans created blue from rare minerals, synthetic ancient formulas, and plants.
Delftware or Delft pottery, also known as Delft Blue (Dutch: Delfts blauw ) or as delf, is a general term now used for Dutch tin-glazed earthenware, a form of faience.
The best homemade solution to clean bathroom tiles is an equal mix of vinegar and water with a dash of dish soap. Pour into the bottle and let it sit for 5 to 10 minutes before scrubbing tiles and rinsing well.
All tiles absorb water to some degree, even low porosity porcelain tiles. The problem here is that the biscuit or body of the tiles have become saturated with water. As the biscuit soaks up water it becomes darker and if the glaze on the tile is white or a very light in colour it tends to be translucent or see through.
While vinegar is a popular cleaning agent due to its disinfectant properties, its acidic nature can dull the surface of porcelain tiles over time. Here's what you should consider if you're cleaning porcelain tile with vinegar: Use Diluted: If opting to use vinegar, always dilute it with water.
For anyone who notices this discoloration near a plumbing fixture, you most likely have copper piping. Copper eventually oxidizes which will create blue and green stains on sinks, bathtubs, showers, toilets, and the piping itself.
Bathroom design is shifting toward immersive, tactile, and natural aesthetics. The newest overarching trend is "tile drenching"—extending a single, continuous tile finish across floors, shower surrounds, and even ceilings to create a spa-like envelope.
Porcelain tile is one of the most durable materials available, lasting 50 to 60+ years with proper installation and basic maintenance. Because it is fired at extremely high temperatures, it is dense, highly resistant to moisture, and stands up remarkably well to heavy foot traffic.
To make a bathroom look expensive, avoid loud, trendy, or purely stark colors. Instead, design professionals recommend deep, moody jewel tones (emerald green, navy blue) or sophisticated, warm neutrals (creamy beige, taupe, deep olive). Paired with the right finishes, these palettes evoke a luxurious spa feel.
Outdated tile colors generally include dark brown-beiges, heavy cool grays, bright pastel shades, and overused glossy white subway tiles. Designers recommend avoiding these in favor of warmer neutrals and organic, nature-inspired hues.
In 2026, bathroom color trends are defined by cozy, earthy, and nature-inspired palettes that create a relaxing, spa-like sanctuary. Stark, cool whites and harsh blacks are out, replaced by enveloping warm neutrals, soothing herbal greens, and vibrant pastel tones.
Simple, safe, and seriously effective: Just mix: 💧 Warm water 🧴 A splash of Dawn dish soap 🧪 A little hydrogen peroxide or white vinegar Spray it on, let it sit, and wipe clean — your tile will thank you. Perfect for keeping grout bright and surfaces gleaming without harsh chemicals.
Bathroom tiles should not change colour over time. If you are experiencing this, it could indicate that you have a water leak, which is causing high levels of water absorption. We recommend enlisting the help of a professional to get to the route of the problem.
Never use abrasive cleaners, wax-based polishes, or harsh chemicals like bleach and ammonia on your tile. Also, strictly avoid steel wool, hard-bristled brushes, and acids like undiluted vinegar on natural stone, as these will scratch the surface, strip the protective finish, and permanently discolor or degrade the grout.
