SFA Sanigrey vs traditional drainage: a real-world installation cost comparison in Vietnam

Key highlights

• Context: Commercial fit-out projects always start with the same question: what is the total cost?
• Problem: Traditional drainage isn't just expensive in materials and labour — the hidden cost of business disruption is often the biggest concern.
• Solution: SFA Sanigrey installs in 2–4 hours, requires no floor drilling, and causes zero business disruption — making it a significantly more cost-effective option.
• Conclusion: Real-world data from clinic and café chain projects in Ho Chi Minh City shows SFA is the more economical choice in most commercial renovation scenarios.

How much does it really cost to add a sink in a commercial space?

When a business owner or project manager asks about adding a new sink or drainage point to an operating space, the first question is always the same: how much will it cost?

The answer depends heavily on the installation method chosen. In Vietnam, two very different approaches exist — and they diverge significantly not only in direct costs, but also in hidden costs from business disruption.

This article draws on real project data from Ho Chi Minh City to provide an honest cost comparison between traditional drainage systems and SFA Sanigrey macerator pump solutions.

Traditional drainage: low material cost, but very high hidden costs

Traditional drainage relies on gravity — wastewater flows through 100mm+ PVC pipes embedded beneath the floor at a minimum slope. It sounds simple enough, but adding a new drainage point to an operating space requires a full construction process:

• Breaking through the floor slab to create a channel for the new pipe
• Running PVC pipes from the new fixture back to the existing drainage stack
• Patching and finishing the floor surface after pipe installation
• Shutting down all or part of the affected area during works

Actual installation time for a single new drainage point: 3–5 working days. The affected area is typically out of operation for at least 1 week, including preparation and finishing time.

Spec to remember: Average cost for a traditional drainage point in Vietnam: VND 15–25 million per point — not including revenue lost during the closure period.

SFA Sanigrey: an advanced investment that costs less than you might expect

Instead of breaking the floor to lay large pipes, the Sanigrey pump unit is mounted behind the sanitary fixture and pushes wastewater through a slim 22–32mm pipe to the nearest existing discharge point — even if that point is up to 100m away.

The actual installation process:

• Mount the pump unit behind or beneath the fixture
• Connect the 22–32mm discharge pipe — routed along skirting boards or through a false ceiling
• Connect to power and run operational checks

The entire process is completed in 2–4 hours. No business disruption required.

Sanigrey pricing varies depending on the product line — residential or commercial — and the specific application requirements. When factoring in total project costs including labour, installation time, and business continuity, SFA Sanigrey is typically a significantly more cost-effective choice than traditional drainage for commercial renovation projects.

Spec to remember: SFA Sanigrey installs in 2–4 hours vs 3–5 days for traditional drainage — with zero days of business disruption.

Real-world cost comparison: traditional vs. SFA Sanigrey

The data below is drawn from actual projects in Ho Chi Minh City, including a medical clinic and a café chain.

Medical clinic project, Ho Chi Minh City: Adding 3 handwash basins in the examination area. The traditional approach was estimated to require 2 weeks of partial shutdown. The SFA Sanigrey solution was completed in one working day, with no disruption to the appointment schedule, and delivered meaningful overall cost savings.

Café chain project, Ho Chi Minh City: Each new outlet uses a standardised SFA Sanispeed installation for the brew bar area. Average installation time is 3–4 hours per location, with consistent and predictable costs — a critical factor when scaling a chain.

When should you choose SFA Sanigrey?

SFA Sanigrey is the optimal choice in the following situations:

• Leased premises with tenancy clauses prohibiting structural floor modifications
• Operating spaces that cannot tolerate extended downtime
• Fixtures located far from the existing drain — beyond the reach of gravity drainage
• Rollout projects requiring consistent, predictable installation costs across multiple sites
• Tight renovation budgets where every line item needs to be optimised

Traditional systems remain appropriate for ground-up new builds or major renovation projects where structural intervention is permitted. Outside of those scenarios, the total real-world cost — including hidden disruption costs — tends to favour SFA Sanigrey.
