What are 2-separation, 3-separation, and 4-separation?

N-separation in the bathroom is to isolate different functions of the bathroom separately, which is different from the traditional, small, crowded and wet toilet .

Traditional bathrooms that are not separated

The bathrooms in old houses are not only small in size, but also have bathing, toileting, and brushing teeth all crowded together.

2 Separate bathroom

It is divided into two types, dry and wet separation and external toilet

In a bathroom with dry and wet separation, the toilet and toilet will not be separated when taking a bath. Keeping the sink wet will not only prevent it from falling, but also prevent the cabinet from becoming damp and moldy.

For bathrooms with an external sink, move the sink outside the bathroom. If someone goes to the bathroom, it will not affect washing. You can also use the corridor outside the bathroom.

3-separate bathroom

The three-separated bathroom we most often talk about, the shower, sink and toilet are separated into three independent spaces, which can accommodate three people using them at the same time.

Four separate bathrooms

On the basis of the three separate bathrooms, the functions of washing and changing are also added, so that four people can use it at the same time without any problem.

Is separation necessary?

Separating the wet and dry parts of the bathroom is highly recommended and should be done no matter what.

Because a bathroom with dry and wet separation can ensure the dryness, cleanliness and hygiene of the bathroom, and can also greatly extend the service life of bathroom cabinets and other items.

Because water will not splash directly on the door, the bathroom can also use a beautiful and beautiful wooden door, which can also be consistent with the doors in other rooms, so that the visual effect will be very good.

A small bathroom can also achieve dry and wet separation. The specific method will be mentioned later.

Whether it is made into three-separation or four-separation depends on the number of people in the family and the size of the bathroom.

The bathrooms in Japanese houses are generally three-separated or four-separated, because they often have only one bathroom for a family of three or four.

In Chinese residences, the configuration of double bathrooms is very common, so there is no need to have three separate bathrooms.

To achieve 3-separation and 4-separation, the shower, toilet, sink, and dressing area must meet the following size requirements.

You can arrange and combine the following functions in different ways like building blocks.

If your bathroom cannot meet the corresponding dimensions, it means that your home cannot be 3-separated or 4-separated.

Remedy that cannot separate dry and wet areas

Because the bathroom area is too small or the pipeline is limited, there is no way to separate dry and wet areas, so use the following methods to solve this problem. .

Step one: Find a slope in the bathroom

No matter how big the bathroom is, the floor cannot be level and must have a slope.

The floor drain (or squat) is the lowest point in the bathroom. No matter where you pour water in the bathroom, the water must be able to flow into the floor drain without any obstacles, and there must be no accumulation of water.

For ordinary bathrooms, look for slopes. The general slope is 5‰.

But the steeper the slope, the faster the drainage, and the less likely it is for water to flow everywhere.

Tell the bricklayer to make the slope bigger, and the bricklayer will understand.

Step 2: Install the floor drain in the shower area

The floor drain is not like the toilet. The pipe is thinner and less likely to be clogged. It is easier to change the location.

A shallow groove is dug in the floor and the pipe is pulled through.

If possible, move it under the shower area for easier drainage.

Step 3: Choose a floor drain that drains water quickly

All the water flows to the floor drain, so the next step is to make the floor drain drain faster.

The humble floor drain core is very important.

The lead sinking type, T-type and silicone heads are all very fast in water, and the deep water seal is the slowest.

Step 4: High-power bathroom heater

No matter whether you are in the north or south, east or south, or whether you have an exposed bathroom or a hidden bathroom, as long as you choose a bathroom heater well, the bathroom will definitely not be damp.

Most of today's bathroom heaters are three-in-one lighting, exhaust fans, and air heaters (light heaters will soon be eliminated), and there is no need to install an exhaust fan separately.

This exhaust function is the same as that of a range hood, which sucks the air out of the room.

So develop a good habit and turn on the exhaust fan after taking a shower. The water vapor will be removed quickly, and the bathroom will become fresh and dry in no time.

Smell and moisture don’t exist at all.

The power of the exhaust fan is only 20~50W, and the power consumption is very low. If you like, you can leave it on 24 hours a day.

Step 5: Please hang a shower curtain

The smaller the bathroom, the more necessary it is to hang a shower curtain.

Use a shower curtain to prevent water from splashing around and making everything wet.

The shower area is too small and the shower curtain easily floats up and sticks to the body.

Use a shower curtain to block bathroom cabinets and toilets instead of surrounding yourself.

The floor may get wet from splashes, but the bathroom cabinets and toilets are guaranteed to be dry.

Step 6: Use water retaining strips to rescue the problem

If the slope of the ground is not correct and water overflows all over the floor, you can use water retaining strips to rescue it.

Buy PVC waterproof strips on Taobao and ask the seller to cut them to the required length.

Long, curved, U-shaped and diamond shapes are all available.

Curve to save the country: go directly into the bathtub

If you like to soak in the bathtub, you don’t have to worry about finding a steep slope, and there is no need to install water retaining strips. Just stand in the bathtub and wash.

The only thing not to forget is not only to buy a shower curtain, but also to put the lower end of the shower curtain into the bathtub, otherwise the water will flow down the shower curtain and eventually flow all over the floor.

For a small bathroom, you can choose a small bathtub, which can be as small as 0.8 meters long. The Japanese-style sitz bathtub can be as small as an insane 0.6 meters. Apart from being a little troublesome to get in and out, there are no disadvantages.

Want to try floor heating?

Of course you can have floor heating in the bathroom!

For the sake of safety, it is best to apply two layers of waterproofing on the ground: before laying the floor heating, apply a layer of waterproofing on the ground.

After laying the floor heating, cover the floor heating with cement, then apply a layer of waterproofing, and then you can lay the ceramic tiles.

After installing floor heating in the bathroom, the floor dries very quickly in winter, so you don’t have to worry about water accumulation.

How to separate wet and dry in a small apartment

Method 1: Move the washing machine

The bathroom is not big enough, so first remove the washing machine.

The kicked-out washing machine should be placed on the balcony or kitchen, as long as there is a place with water supply and drainage.

Some residential areas have separate rainwater pipes and sewage pipes, so you have to ask the property management company whether you can put a washing machine on the balcony.

Most houses with balconies for housework have the washing machine installed on the balcony by default.

Method 2: Separate toilet and shower

If there are two bathrooms at home, it is better to consider removing the shower in one of the bathrooms, leaving only the toilet and sink.

This will make the bathroom more spacious and will not affect going to the toilet.

Method 3: Kick out the sink

Putting the sink outside is a very effective method and can save a lot of area.

When you are in a hurry in the morning, brushing your teeth, washing your body, taking a shower and going to the toilet do not conflict with each other.

A simple external bathroom does not count as dry and wet separation, but because it frees up space for the bathroom, it is possible to achieve the simplest dry and wet separation in a small bathroom.

The easiest way to install an external sink is to install it next to the wall of the bathroom.

Move outside the bathroom and run the sewer pipe through the wall. The operation is relatively simple.

If conditions permit, the external sink can also be placed side by side with the washing machine.

Method 4: Expand the bathroom shower area

Do not change the location of any existing sewer pipes, but simply expand the area of ??the shower area.

After taking a shower, the water still flows away along the ground through the original floor drain.

The hot and cold water pipes connected to the shower will be changed during decoration, so it is not difficult to adjust the position.

In fact, the above methods are not only suitable for small bathrooms, but also for large bathrooms that do not want to separate dry and wet areas.

The core purpose of dry and wet separation is to prevent bath water from getting wet in the bathroom, and prevent the entire bathroom from turning into a water curtain hole after taking a shower.

As long as this goal can be achieved, anything is fine.
