How to design the shower room without threshold stone water stop?
Looking at these two pictures, the shower water stop is usually made of concrete or stainless steel water stop to prevent the water vapor in the shower room from spilling into the dry area of the bathroom, which has the disadvantage of having a high threshold stone.
However, many Internet celebrity shower rooms now have no height difference shower room threshold, how should that structure be realized?

This is a very good question, and it is often asked in my "Deepening Live Room", so let's explore it in a few steps:
1. The role of the threshold stone:
As we all know, the purpose of the waterstop barrier is to prevent the water from flowing from the wet area to the dry area, causing the situation of destroying the ground finish of the dry area.
△ There is no water-stopping barrier in the paving layer, and the water flows through the paving mortar
In addition to the height difference treatment on the finished surface in the place of dry and wet partitions, the concrete water stop or stainless steel water stop must also be done at the base of the paving, the purpose of which is to prevent water from passing through the paving layer under the finishing material, and "wetting" the paving layer in the dry area and then destroying the finished surface of the dry area.
△ Stainless steel waterstop barrier
△ Concrete water-stopping barrier
2. Can the shower room be without a threshold stone?
However, in this way of design, there will be "high" threshold stones and water retaining strips. Now many Internet celebrity spaces hope to cancel the threshold stone of this "strip" height difference, especially in the shower room, which is often said to be "roll-free shower, so that there is no height difference between the shower room and the bathroom."
△ No height difference and no threshold shower
The design of this kind of shower room without height difference and no threshold stone, in essence, mainly relies on the method of "finding slope to the strip floor drain" to control the flow direction of the overflow and achieve the purpose of not letting the water flow out.
Therefore, the location of the strip drain becomes a key point
As shown in the figure above, it is set under the shower, and it is conceivable that if the slope of the shower room without a threshold is less than 2% or the depth of the shower room is less than 2M, the water flow will flow to the dry area outside the shower room without the barrier of the threshold stone. And the slope is too large, the precision of wall tile cutting will be higher. Therefore, this design is not advisable!!
The ideal way to achieve this is to put the strip drain on the "dividing line" of the dry and wet partition, find the slope on both sides to the dividing line, and at the same time prevent the water flow from penetrating from below the base layer through the strip drain itself as a "metal waterstop barrier", such as the following:
△ A strip-shaped floor drain is set on the dry and wet dividing line
△ Strip floor drain overflow effect
△Three-dimensional schematic diagram
△The wider the floor drain, the better the water retention effect
△The wider the floor drain, the better the water retention effect
△ Scene map of the non-threshold shower
With this principle in mind, let's finally look at a set of node graphs
△ Ultra-thin and narrow-sided bar drain node diagram
△ Hidden strip drain node graph
△ Ultra-thin and narrow-sided bar drain node diagram
△ Customized stone cover slat-shaped floor drain node diagram
Of course, although the use of this strip floor drain is beautiful, but in the process of use, if it is not cleaned in time, the following situation will occur, hiding dirt and dirt, and hair is all over the sky.
△ Hidden under the floor drain cover
So, the question is, in a situation like the picture below, how to clean the hidden floor drain cover?
