one of the concerning factors for users that might have unknown possible reasons is cracked tile of the bathroom wall. Cracked bathroom tiles are frustrating for many homeowners. In addition to cracks that spoil the beauty of bathroom design, they are also causing for concern and should be repaired immediately. But rather than just smearing sealant over the crack, find out what's causing the crack first and see if that portends a bigger problem. So why do bathroom tiles crack? Tiles are the best choice for bathrooms because they are inexpensive, durable, and moisture resistant. Materials can crack due to hard knocks, heavy loads, spacer joists, check joint installations, concrete substrate issues, improper adhesive application, and poor quality tile. The tiles have excellent moisture resistance and are the first choice for kitchens and bathrooms. They are inexpensive and easy to maintain. However, the material is prone to cracking over time. This results in homeowners spending around $185 to $425 to fix the tiles in their homes and prevent the cracks from growing again. But by understanding the possible causes of cracked tiles, homeowners can avoid unfortunate situations. 
It also saved them a lot of money that would have been spent finding suitable flooring materials and paying contractors to install new materials. Avoiding the tiles from breaking also makes a difference keep up the stability of the building's foundation. Here are the six most common causes of cracked bathroom tiles:
- Bash or reload
If it extends over a single tile, check for cracks in the tile. This usually happens when the tile surface is hit hard. He even left broken parts where he hit hard. Another possible cause is an overload on part of the bathroom. Tile manufacturers must adhere to the ASTM C648 standard for tensile strength. This means the tile should hold approximately 250 lbs. pressure. Some specialty tiles have higher breaking points, up to 400 lbs.
- Incorrect joist spacing
A joist is a beam under the subfloor. They hold everything in place. A huge gap between the two joints will bend the plywood too much. This eventually led to structural instability, causing the tiles above to crack. Joist spacing should follow the International Residential Code to prevent excessive deformation of the plywood. Adding more cushion structure also helps limit flexing to prevent tile cracking.
- Installation of the control connector
Control joints are applied to the concrete slab to control possible future cracks. They are used to relieve pressure and movement due to shrinkage or expansion of concrete or masonry. 
These pre-planned cracks are placed in strategic areas of the ground to deliberately create weak areas. However, laying tiles over concrete slabs with controlled joints is not a wise choice. Chances are that concrete slabs will use control joints, causing the tiles to crack.
- Problems with concrete supports
The condition of the concrete substrate can also affect the tiles. Here are two issues homeowners may encounter when working with concrete substrates that damage bathroom tiles:
- Untreated
New concrete poured on a house goes through a process called "curing". During this time, the material evaporates excess moisture and shrinks. The hardening of concrete is a dynamic process that helps the aggregates in the mix to bind together tightly. Installing tiles before the concrete has fully cured can stress the floor and cause fine cracks to develop. According to the American Tile Council, concrete should be allowed to cure on its own for 28 days before installing flooring. Other manufacturers think it should only take 14 days, but it's better to wait longer to avoid unwanted cracks in the bathroom tiles. 
- rupture
Concrete floors often develop cracks over time. But despite this problem, concrete is still considered the best substrate for tiles. When the concrete begins to crack, the movement is transmitted to the tiles above. This can cause reflective cracks to appear on the bathroom tile surface. The best way to determine if a cracked substrate is causing the tile to crack is to observe the formation of cracks. A long crack that spans multiple tiles is an indicator of a cracked concrete substrate underneath. The best solution to this problem is to install a crack isolation membrane before replacing the tiles. The film separates the movement of the slab and the concrete support to prevent the formation of reflective cracks.
- Using the wrong adhesive
Finding the right type of tile adhesive is also important to prevent cracking. If the wrong adhesive is used, the tile will not bond properly to the subfloor. Tiles are more prone to large cracks if there is no proper support to hold them in place. 
- Poor quality tiles
Tile is the only visible part of an installed floor, which is why most homeowners think there is something wrong with the tile. Although this is not the case in most cases, it is also possible that the contractor simply installed substandard tiles for the bathroom. Prevent such accidents by checking the specifications of the tiles before buying them in bulk. Buy tiles from a trusted retail line, such as a home improvement store or a trusted online store. It assures you that the tiles are manufactured according to ANSI and ASTM standards. Once you find cracks in bathroom tiles, it's important to repair or replace them quickly to prevent further damage. Penetrates floor and tub tiles, ultimately affecting the integrity of the home's foundation. Homeowners may also have moisture issues in parts of their homes where there should be no water. Mold, mildew, and other pests can also hide on broken tiles that have soaked in water. This forces homeowners to remodel their homes, creating unnecessary costs that can be avoided or replaced with quick tile repairs. 
bathroom wall tile
it is important to know what type of tile to choose for the bathroom wall as it will waste your time and money. Some tiles are not best suited for bathroom walls. The wrong choice will result in cracking. Also there are some ways to prevent this conclusion. Like most problems, preventing tile cracks is also better than fixing them. Here are some tips to prevent cracks in bathroom tiles:
- Make sure that quality tiles for bathroom floors and walls are purchased from a trusted supplier.
- Find the right type of tile that can withstand different levels of humidity and heat. If you prefer a steam shower, keep in mind that tiles can crack when heated for long periods of time.
- Tiles must be installed with the correct material.
- Use crack insulation film to prevent reflective cracks.
- Check that the correct adhesive is used to bond the tile to the subfloor.
- Let a professional contractor handle the job rather than installing the tiles yourself.
If there are only tiny or hair-like cracks in the bathroom tiles, they can be easily repaired with putty and paint. 
Here are some steps to follow when repairing cracked shower tiles:
- Clean the tiles before you start anything. Soap and water are enough to remove mud, dust and dirt from bathroom floors, but be sure to rinse them off.
- Dry the cracked tiles with a towel to prevent the soap from mixing with the sealant. Also, be sure to wait a few minutes or dry the inside of the crack with a hair dryer.
- Mix the paint with putty until you get the right color. Store-bought kits often have detailed instructions and color-matching charts to guide owners on how to properly use the product.
- Use a spatula to spread the mixture over the cracks. Remove excess putty and wait for it to dry.
- Once completely dry, seal the package with a sealant.
- Wait at least 48 steps for the putty and sealer to harden before walking on the tile.
- When to replace bathroom tiles
- It is best to replace bathroom tiles when the cracks are too large or a single tile has many cracks. The first thing to do is to break the tiles with a hammer. Scissors can also be used to remove adhesives and pick up tiles.
After discarding the damaged tiles and clearing the area, it's time to get ready to replace the tiles. Apply an appropriate amount of adhesive to the back of the new tile and place it in an empty spot in the bathroom. Hold up for the adhesive to dry totally before filling the edges with new grout. Once the grout is dry, wipe the new tile clean with a damp cloth. We all want our bathrooms to be beautiful and safe to use, but cracks in walls, floors, and bathtubs are never a good sign.
