A Must-Read Before Planning Water and Electrical Positioning

When it comes to home renovation, the positioning of water supply and electrical points is extremely important. If this step is not handled properly, many products may not be installed correctly later, and daily use can be inconvenient or even problematic. This is why most homeowners pay close attention to this stage of the renovation.

Below is a clear, structured explanation of how water and electrical positioning is typically planned during a home renovation.

Step 1: Preparations Before Positioning

Before on-site positioning begins, several key tasks must be completed in advance. Only after these preparations are finished should the positioning appointment be scheduled.

1. Finalize the floor plan

The designer completes the layout based on the homeowner’s needs, clearly defining how each area of the home will be used.

2. Complete water and electrical diagrams

Based on the finalized layout and functional requirements, the designer prepares detailed water and electrical plans and brings them to the site on the positioning day.

3. Confirm appliance, fixture, and furniture dimensions

Accurate dimensions for appliances, bathroom fixtures, cabinets, and furniture are essential. On-site positioning relies heavily on these measurements to ensure smooth installation and comfortable daily use later.

4. Clarify household living habits

Water and electrical positioning is not fixed or universal. It should be adjusted according to how each family member uses the space. These habits should be clearly discussed before work begins.

Step 2: Scheduling the On-Site Positioning

On the day of positioning, several parties should be present, including:

• Homeowner
• Designer
• Project manager
• Water and electrical technician
• Representatives from product suppliers (such as central air conditioning, cabinets, bathroom fixtures, whole-house customization, doors and windows, smart home systems, etc.)

The exact participants depend on the products used in the home.

Once the time is confirmed, suppliers bring their technical drawings and product specifications to the site. The renovation company prepares tools such as laser levels, markers, and measuring tapes. The on-site positioning process can then officially begin.

Step 3: On-Site Water and Electrical Positioning

After all preparations are complete, the actual positioning work starts. This stage typically includes the following parts:

1. Water Supply Positioning

Water supply lines are relatively straightforward, so this part is usually completed first. Positioning mainly involves the kitchen, bathrooms, and balcony.

Kitchen

Key points include:

• Water inlet valve under the sink
• Hot and cold water supply for the sink
• Reserved hot and cold water connections for the gas water heater near the window

All positions should follow the cabinet supplier’s drawings.

Bathroom

Water point requirements vary depending on bathroom functions. Most bathrooms include:

• Hot and cold water for the sink
• Cold water for the toilet
• Hot and cold water for the shower
• Cold water for a washing machine (if installed)

The renovation company provides standard installation heights, which the homeowner can adjust according to personal and family habits.

Balcony

Only balconies used for daily chores typically require water supply. Common configurations include:

• Hot and cold water for a utility sink
• Cold water for a washing machine

Recommended positions are provided by the renovation team and fine-tuned based on homeowner preferences.

2. Drainage Positioning

Drainage positioning is mainly adjusted based on living habits. If bathroom fixtures or appliances have already been purchased, suppliers will provide drainage requirements. The renovation company then determines the most suitable drainage locations based on these specifications.

3. Switch and Outlet Positioning

Most homes follow several standard height references:

• 300 mm – Standard power outlets
• 1300 mm – Light switches
• 1800 mm – Air conditioner outlets
• 2200 mm – Range hood outlets
• 150 mm above countertop – Kitchen outlets

Once these reference heights are understood, positioning becomes much more efficient.

4. Ceiling Light Positioning

This is generally the simplest step, as ceiling lights follow the designer’s lighting plan. The homeowner only needs to confirm that the locations match daily usage habits.

Minor adjustments can still be made later, even after ceiling installation. It is important to communicate with the air conditioning supplier to avoid conflicts between air ducts and lighting fixtures.

Step 4: Final Confirmation

After positioning is complete, technicians mark all water and electrical points directly on the walls. The renovation company then conducts a full walkthrough of the home, starting from the entrance, to recheck every point.

The homeowner and relevant suppliers should participate in this final inspection. If anything feels inconvenient or unsuitable, adjustments can still be made at this stage.

Once all parties confirm the positions, the renovation company takes detailed photos for records. This ensures that all information is preserved before wall cutting begins.

Conclusion

Water and electrical positioning is essentially a multi-party coordination process during home renovation. As long as each step is handled carefully, the process itself is not complicated.

For homeowners, the most important task is to clearly communicate family needs and daily habits. The technical execution can then be confidently entrusted to the renovation team and product suppliers.
