On functionality , the bathroom area can be organized into four major activities. This include wash basin area, water closet WC area, storage area and shower area.

Depending upon the scope of the bathroom remodel work , the existing bathroom dismantling work can be initiated in logical sequence.

The dismantling is a noisy operation and  also generate considerable dust if the existing structure is a brick wall construction.

However , for wooden structure with cement wall panel construction ( US And European countries ) the removal of the existing structure is relatively much easier.

The first step of the dismantling work is the removal of existing cabinets , wash basin , WC commode seat and other plumbing fixtures such as taps and mixer units.

In most situations , you may have to redo the internal bathroom plumbing work and replace the existing underground sewer line pipes. This decision depends upon the condition of the existing plumbing and sanitary lines.    

However , if the existing plumbing is to be retained then the due care should be taken during the removal process. The existing plumbing and other service lines might get accidentally either weakened or damaged.

This sunk portion allows enough space for underground sewer drainage pipes required for the commode , wash basin drainage pipe and the drainage pipe for shower area enclosure ( floor trap ) connection.

This sunken area is provided with special waterproof treatment. Due care should be taken during the dismantling process to protect the waterproof treatment of the bathroom area.

The waterproofing of the bathroom area is a time consuming and expensive process. Please check the condition and its effectiveness of the bathroom waterproof layer before you proceed further.

The layout of the plumbing pipes inside the bathroom depends upon the location of various plumbing fixtures such as wash basin , flush tank for WC , wash area floor trap and the geyser.

The bathroom drainage is another important system that needs to be planned and installed properly for its trouble free functioning.

The bathroom drainage system consist of two types of pipe lines to handle two different types of discharge. The first type of pipe does not include any solid human waste and this discharge is called the sullage.

The sullage include the discharge mainly from the wash basin and the bath shower area discharge. The sullage is relatively safer to handle and does not generate foul gases in the pipeline.

The sullage discharge drainage pipeline is connected to the inspection chamber through a gully trap placed outdoor. The gully trap creates a water seal and prevents the foul gases from entering into the house drainage.
