Hello everyone, I am a home forum focusing on sharing knowledge about home furnishing and decoration. Here, I will try my best to share some of the knowledge I know with everyone, and I hope everyone can support it!

Article introduction: At this stage, almost all houses with an area of ​​more than 100 square meters have two bathrooms, one of which is in the master bedroom. Therefore, a very common phenomenon occurs, that is, the bathroom in the master bedroom often faces the bed in the bedroom. However, many friends don’t like the bathroom door of the master bedroom facing the bed in the bedroom, so they try to modify the bathroom door opening during renovation. So is it possible to change the bathroom door opening? What should be done? What problems will occur if the hole is not properly modified? These are the questions we need to understand. Otherwise, if the door opening shifts, various problems will occur later, which will be very troublesome. Home Furnishing Forum would like to analyze some issues related to changing the bathroom door opening in this article.

What are the characteristics of the bathroom

The first and most significant feature That is, the humidity in the bathroom is relatively high:

Everyone knows that the ventilation conditions in bathrooms are generally not very good. Many bathrooms do not have exterior windows, and some bathrooms have exterior windows. , but the opening angle of the outer window is very small. These problems lead to poor air quality and high humidity in the bathroom.

The second most significant feature is the bathroom floor, and some walls in corresponding areas need to be waterproofed:

If these locations are not properly waterproofed or are damaged, water leakage may occur. First, it can penetrate downstairs, causing the roof downstairs to be soaked; second, it can penetrate to the other side of the wall, causing the wall decorative layer to peel off.

The third most striking feature is that there are many water facilities and sanitary ware in the bathroom:

Because there are basically all kinds of water in our bathrooms. It is necessary to install a toilet, washbasin, and shower room. In addition, some bathrooms have bathtubs. The existence of these facilities will lead to frequent water in the bathroom.

The fourth significant feature is that many bathrooms will smell:

If the bathrooms in our home If the bathroom floor drain or the toilet is not properly sealed, odor may occur. In addition, if the bathroom in the home is not used for a long time, the water seal will dry up, and there will also be odor.

What are the common problems with bathroom doors and what are their solutions

Introduction to the problem: Because many of our master bedrooms now have bathrooms, and the bathroom doors open into the master bedroom for the convenience of use. However, this way of opening the door brings two problems: First, the bathroom door of the master bedroom will directly face the bed in the bedroom. But many friends don\’t like this approach. Second, the smell from the bathroom will return to the bedroom, causing bad air in the bedroom. These are some common problems with bathroom doors.

Solution: For the bathroom door facing the bedroom bed, the common method we all take is to move the bathroom door to On the other side of the bathroom wall to hide from the bed in the bedroom. Because at this time we need to keep the bathroom in the master bedroom. Of course, it is also possible to change it to other types of rooms.

Existing problems: 1. The displacement of the bathroom door opening will cause damage to the bathroom wall. 2. The barrier under the bathroom wallWater tables can also be damaged. Third, the original hole still needs to be sealed. These are all the problems caused by changing the bathroom door opening.

Problems that need to be solved: The first problem that needs to be solved is the removal and production of the water retaining platform on the lower side of the bathroom wall to avoid this problem. There is water seepage in the area. The second problem that needs to be solved is that the wall built later and the opening of the wall may cause cracks in the wall. The third problem that needs to be solved is the problem of opening holes in the wall to reinforce the wall.

What are the wall types in the bathroom

• The first type of bathroom wall is a shear wall, which is a load-bearing wall. For example, in a bathroom with an exterior window, the side wall with the exterior window is the exterior wall of our building, so this part of the wall is basically a reinforced concrete shear wall. No modifications are allowed to this type of wall during decoration, including chiseling or trenching.
• The second type of bathroom wall is a secondary structure wall built at the back. The back-built secondary structure wall is basically a wall made of hollow bricks or air-entrained mixed earth blocks as the building materials, and then built with cement mortar. The thickness of this type of wall is generally 120mm thick. Therefore, it is very easy to retrofit without damaging the overall stress-bearing structure of the house. Secondary structure masonry walls are generally common in high-rise residences at this stage, and it can be said that almost all use this method.
• The third type of bathroom wall is a brick wall. Brick walls generally correspond to brick-concrete structures. In other words, after our bathroom walls are built with bricks, concrete is poured into each corner by setting structural columns. This kind of brick wall is also a load-bearing structure. For this kind of load-bearing structure, it is strictly forbidden to cut grooves on it. Bathrooms with brick walls are usually found on low-rise buildings in the past.buildings and some bungalows.

What problems will be affected by changing the bathroom door

• The first and most likely problem is that the wall at the modified location is prone to cracking. This is because after we change the bathroom door opening, we need to cut an opening on the wall at the new opening location, and at the same time seal the original opening. In this way, when we seal, we create two different times of masonry, so these parts are prone to cracking. In addition, when we cut on the wall, if we do not handle it properly, the four corners of the hole will also be prone to cracking.
• The second problem that is likely to occur is that the waterproofing of the bathroom may not be easy to handle. This is because after we changed the opening of the bathroom, the wall was masonry and opened, which destroyed the integrity of the original overall structure. Then after we apply the waterproof coating, it may cause these waterproof coatings to crack from this part, thus losing the waterproof effect.
• The third most common problem is that water seepage and leakage occur in the lower part of the original hole. Because there is a 300mm high retaining wall at the root of the bathroom wall, and we seal the original hole, this part must be properly treated at this time. Otherwise, the chance of water leakage in this part is very high.
• The fourth common problem is that the lower part of the doorway of the new opening needs to cut off the retaining wall around the original bathroom wall. After we cut off the retaining wall, we destroyed the integrity of the ring beam. If the integrity of the ring beam is damaged, the root of the hole will be prone to water seepage and leakage later.

When the bathroom door is repositioned, how to deal with the original opening

• The first step is to chisel We need to chisel away the plastering mortar layer around the original bathroom door opening and the concrete on the ground. Simply chisel. The purpose of making a rough surface is to prevent the original water in these parts. After hollowing and cracking occur in the mud mortar, it is very easy for uniform rectangular hole-shaped cracks to appear in the wall we build in this area.
• The second step is to make the original. The water retaining platform of the bathroom entranceThe suggestions given by the individual at this time. The suggestion is to drill holes on the ground, the depth of which is usually 60mm. Then use reinforcement glue to plant the steel bars. At the same time, drill holes on the side of the original concrete water retaining platform to plant the steel bars, and then tie out the water retaining platform. Rebar.
• The third step is to set up the formwork and then pour the concrete. Soil.We need to re-install the formwork at the position of the bathroom water retaining platform, and then pour concrete with C20 or above inside the formwork, and then use a vibrator or other vibrating tool to vibrate and compact it at least. After more than a week, remove the template.

• The fourth step is to plant steel bars on the wall Many friends believe that sealing the opening is necessary. When laying bricks, do notReinforcement needs to be installed. Personally I think this approach is incorrect. My personal suggestion is to plant steel bars throughout the hole. The diameter of the steel bar for planting is generally 8mm or 10mm. The length is the length of the hole plus the depth of the planting plus the overlap length. This can be done by planting bars on both sides and then tying them in the middle. In the vertical direction, two steel bars are planted every 50cm.
• The fifth step is to build the hole. When building masonry, it is recommended to use masonry made of the same material as the original wall. During the masonry process, I personally recommend that you use red bricks or Xiaohui bricks on the bottom three layers of the wall, and then use air-entrained blocks or hollow bricks on top. The last 300mm above cannot be built to the top at one time. Then let it sit for at least two weeks before building the top slope.
• The sixth step is plastering. When plastering, be sure to hang the entire surface of the hole with steel mesh, or hang double layers of resistant fiberglass mesh for plastering. The thickness of plastering must be controlled within 20mm, which means that the plastering layer should be as thin as possible. After the plastering is completed, remember to sprinkle water and maintain it to avoid cracking.

How to open a new door opening in the bathroom

• The first step is to flick the thread. If we want to make a hole in the original wall, we should first pop out the line of the hole. For example, the hole we want to open is 900mm×2000mm, then the pop-up line at this time should be 910mm×2010mm. The elastic line should be slightly larger than the final hole we completed by 10mm or about 20mm to facilitate leveling in the later stage.
• The second step is cutting. I personally suggest that when you make a hole in the wall, you first use a cutting machine to cut the hole along the hole line we played. It is not recommended that you use an electric pick directlyGouging will disturb the entire wall. After the cutting is completed, use an electric pick or a sledgehammer to gently chip away at the inner wall, so that the entire hole comes out.

• The third step is to deal with the lower retaining platform. Because when we reopen the opening in the new wall, we will inevitably cut off the water retaining platform at the lower part of the bathroom wall. What we focus on at this time is the handling of steel bars. Because we must have cut off the original steel bars. Of course, if it was made of plain fine stone concrete, there would be no such problem.
• The fourth step is to trim the hole. After we have cut the entire hole and chiseled it out, we need to trim the hole. The conventional method is to use cement mortar for plastering. In this way, we finally get the size of the opening we need to meet our later installation of the bathroom door.

How to deal with the new door opening when the bathroom door is renovated

• First point, we need to add a lintel above the hole we cut. Because we cutThe width of the opening must be at least 800mm. According to the requirements of the specification, lintels must be added to any opening exceeding 300mm.
• Second point, let’s look at the specific method of placing a lintel above the door. We can first make a hole about 200mm wide and 200mm high on both sides of the upper part of the hole. In the end, a hole we appeared was actually a shape similar to a T.
• The third point is the installation of lintels. Llintels, we can make finished lintels outside. For example, the size is 1300mm×200mm×120mm, which is the upper part of the entire hole. This size refers to the length, width, and thickness of the lintel. This size is consistent with the hole cut above our door opening. In addition, formwork can be directly supported on the door opening to tie the steel bars and make cast-in-place concrete lintels.
• The fourth point is filling the gaps in the lintel. If we install prefabricated lintels, there will definitely be a gap between the lintels and the wall after installation. At this time, I personally recommend that you use fine stone concrete to fill these gaps, or use high-grade cement mortar to fill them. It is strictly prohibited to plaster directly without filling the gaps. Because such an approach can cause serious cracking in these areas.
