THE DRAIN PIPE OF THE BATHROOM WASHBASIN IS ABOUT 25CM FROM THE WALL, THE TOILET DRAIN IS 30CM OR 40CM FROM THE WALL, AND THE BATHTUB IS DIFFERENT DEPENDING ON THE SIZE AND SHAPE. >>>More
Toilets in Japan basically use the "three-way separation", which separates the three areas of bathing, washing, and toileting. No matter what kind of house type, one of the most unified and important design ideas is that the toilet room is independent! It does not affect the overall convenience of use, and is independent of other areas.
Angle valves, mixer faucets, hoses, inner and outer wires (for surface-mounted pipes), inner wire elbows, outer wire elbows (for concealed pipes), tees, elbows, pipe clamps, expansion gong wires, rubber stoppers, raw material belts.
Floor drain is generally 50 75, bathtub washbasin is generally 50, toilet 110
The toilet squatting urinal and washbasin are the same drainage pipe, the ground does not need to be dropped, and the squatting toilet has a water trap when it is installed, which naturally has a drop, and the washbasin is higher than the ground, so it will not affect the drainage.
