[Case study - 45] Renovation solution for a 140 m² apartment adding a toilet and relocating the kitchen

Buying an apartment and renovating it to match personal preferences is becoming an increasingly popular trend in central urban areas. However, when changing the layout or adding new functional spaces, drainage systems often become a major constraint.

The 140 m² apartment in District 1 below is a typical example. After purchasing the apartment, the homeowner wanted to redesign the entire space into a 4-bedroom layout with optimized functionality, including ensuite bathrooms inside bedrooms and a new kitchen area that better fits the family’s daily lifestyle.

Key highlights

• Situation: The homeowner purchased a 140 m² apartment in District 1 and renovated it into a 4-bedroom layout based on personal preferences.
• Challenge: The desired locations for the new bathrooms and kitchen had no existing drainage pipes and floor cutting was not allowed.
• Solution: Installing Saniaccess 3 for the ensuite bathrooms and Sanivite for the kitchen area.
• Result: The apartment was renovated exactly as planned without altering the building structure.
  
   

Problem

The apartment has a total area of 140 m² and is located in District 1, Ho Chi Minh City. After purchasing it, the homeowner wanted to redesign the interior layout to better suit the family’s lifestyle, including:

• Converting the apartment into four bedrooms
• Adding private bathrooms to two bedrooms
• Creating a new kitchen area with improved functionality

However, once the renovation plan began, several technical issues appeared:

• The planned bathroom locations did not have existing drainage pipes
• The locations were far from the building’s main drainage stack
• Floor cutting or structural modifications were not permitted

This is a common challenge in apartment renovation projects where the new layout no longer aligns with the original drainage system.

Solution

To solve the wastewater challenge without altering the floor structure, the contractor implemented solutions from SFA Pumps.

Two Saniaccess 3 units from the Sanitoilet solution were installed for the ensuite bathrooms. These units collect wastewater from the toilet and washbasin, then transfer it to the building’s main drainage system.

For the new kitchen area, the Sanivite pump from the Sanigrey solution was installed to collect wastewater from the kitchen sink and other kitchen appliances. This allows the kitchen to be positioned flexibly without depending on the original drainage pipe location.

• Efficient wastewater collection for both bathrooms and kitchen areas
• Flexible installation for apartment renovation projects

Results

By applying the SFA Pumps solutions, the apartment renovation was successfully completed according to the homeowner’s expectations:

• The apartment was renovated without floor cutting
• Two bedrooms now have private ensuite bathrooms
• The new kitchen area was installed flexibly within the apartment
• The wastewater system operates reliably for daily household use
