The entire process begins with meticulous planning and design. This initial phase involves measuring the bathroom’s dimensions accurately and creating a detailed layout. You must decide on the placement of all major fixtures, such as the toilet, shower, bathtub, and vanity, while considering the existing plumbing and electrical points. This is also the time to establish a clear budget, choose a stylistic theme, and select the primary color scheme and materials, which will guide all subsequent decisions and purchases.

Once the planning is complete, the next step is the preparation and demolition stage. This involves removing all old fixtures, tiles, flooring, and any cabinetry that will not be reused. It is crucial to turn off the water supply and electricity to the bathroom before starting this work. Proper protection of the area outside the bathroom is also necessary to contain dust and debris. This phase clears the space for the new installation and allows you to inspect the underlying walls and floor for any hidden issues like water damage or rot.

With the space cleared, the focus shifts to critical behind-the-wall work, including any structural, plumbing, and electrical rough-ins. This is when new water supply lines, drain pipes, and vent lines are installed or relocated according to the new layout. Similarly, electrical wiring is run for new lighting, exhaust fans, GFCI outlets, and any dedicated circuits for heated floors or towel rails. Following this, professional waterproofing, or tanking, is applied to all wet areas, such as the shower zone and around the bathtub, which is an essential procedure to prevent future leaks and moisture damage.

The subsequent phase involves the installation of new surfaces and fixtures. This starts with hanging new drywall or cement board on the walls and laying the subfloor. The new tiles are then installed on the walls and floor, followed by the meticulous process of grouting and sealing. Once the tiling is complete, the major fixtures—the bathtub, shower tray, toilet, and vanity unit—are permanently installed. The plumbing connections for these fixtures are finalized, and the shower valve, showerhead, and faucets are fitted.

The final stage encompasses finishing touches and thorough cleaning. This includes painting the walls or ceiling if they are not tiled, installing mirrors, medicine cabinets, and lighting fixtures. All electrical faceplates and switch covers are put on, and accessories like towel bars, toilet paper holders, and shelving are mounted. A professional deep clean is then conducted to remove all construction dust and residue from the new surfaces. The project concludes with a final inspection to ensure everything is functioning correctly, the plumbing has no leaks, and the electrical elements are working as intended.
