Lavabo and kitchen sink replacement is a service that surveys the site, removes the old fixture, and installs a new lavabo or kitchen sink with correct technique, including checking the water supply and drain lines, waterproofing around the installation point, and connecting the faucet. Sai Gon Home Repair 247 provides this service in Ho Chi Minh City in 2026, with over 7 years of experience in repair and renovation work.
What’s Included in Lavabo & Kitchen Sink Replacement
A proper lavabo or kitchen sink replacement needs to address both the fixture and the related plumbing. Sai Gon Home Repair 247 carries out the full process:
- Site survey: checking the old lavabo/sink, the water supply line, the drain line, and the trap (P-trap).
- Removing the old fixture, cleaning the installation area, and checking the countertop condition (stone, wood, stainless steel).
- Advising on the lavabo or kitchen sink type suited to the space and actual usage needs.
- Installing the new fixture, aligning it correctly, and ensuring it sits level.
- Waterproofing around the installation edge with specialized silicone.
- Connecting the faucet and drain trap, checking the tightness of the entire system.
- Testing operation (water supply, drainage, seal) before handover to the customer.
Signs You Need a New Lavabo or Kitchen Sink
A few signs indicate that repair is no longer a sustainable fix and replacement should be considered:
| Sign | Common Cause | Recommended Action |
|---|---|---|
| Persistent water leak at the lavabo base or sink joint | Failed waterproofing silicone, degraded gasket | Survey and consider replacement |
| Cracks or chips in the fixture body | Impact damage, material degrading over time | Must be replaced — do not continue using |
| Yellowed, worn-looking finish | Long-term use, glaze or coating deterioration | Consider replacing to refresh the space |
| Slow drainage despite repeated unclogging | Old trap, narrowed drain pipe | Inspect and replace if needed |
| Want a different style or material | Kitchen or bathroom renovation needs | Replace to match the updated design |

Common Types of Lavabos Today
Choosing the right lavabo type affects both the look and the complexity of installation. The most common types in Ho Chi Minh City are:
| Lavabo Type | Characteristics | Best Suited For |
|---|---|---|
| Countertop (drop-in) lavabo | Sits on top of the stone countertop, simple to install, more affordable | Townhouses, standard bathrooms |
| Undermount lavabo | Mounted beneath the countertop, seamless look, easier to clean | High-end bathrooms, newly built homes |
| Pedestal lavabo | Built-in stand that conceals the water supply and drain lines | Small bathrooms without a stone countertop |
| Wall-hung lavabo | Mounted directly on the wall, saves floor space | Small bathrooms, modern-style spaces |
Common Types of Kitchen Sinks Today
For kitchen sinks, choosing the right number of basins and material makes daily use more convenient:
| Kitchen Sink Type | Characteristics | Best Suited For |
|---|---|---|
| Single-basin sink | One large basin, saves counter space | Small kitchens, limited-space apartments |
| Double-basin sink | Two separate basins, convenient for washing and soaking at the same time | Family kitchens with frequent cooking |
| Sink with drainboard | Includes a small drainboard area for drying dishes | Kitchens with more counter space |
| Undermount stone sink | Mounted beneath the stone countertop, high-end, seamless look | Modern kitchens with stone countertops |
Common lavabo and kitchen sink brands on the Ho Chi Minh City market include TOTO, INAX, American Standard, Caesar, Viglacera, and COTTO — each brand has slightly different cutout dimensions and connection methods, which need to be checked carefully before installation.

Lavabo & Kitchen Sink Replacement Process
To ensure the new fixture operates reliably with no issues after installation, Sai Gon Home Repair 247 follows a 5-step process:
- Site survey: checking the old fixture, water supply/drain lines, and countertop condition.
- Solution advice: recommending a lavabo/sink type suited to the space, budget, and usage needs.
- Removal and cleaning: removing the old fixture and thoroughly cleaning the installation area.
- Installation and waterproofing: aligning the new fixture correctly, waterproofing around the edge, and connecting the faucet and trap.
- Testing and handover: test-running the water supply and drainage, checking the seal before handover.
What Affects the Cost of Lavabo/Kitchen Sink Replacement
The cost of replacing a lavabo or kitchen sink in Ho Chi Minh City is not fixed — it depends on several practical factors:
- Fixture type: countertop/undermount/pedestal/wall-hung lavabo; single-basin/double-basin/undermount stone sink.
- Material: ceramic, engineered stone, stainless steel.
- Brand and price segment (TOTO, INAX, American Standard, Caesar, Viglacera, COTTO, etc.).
- Condition of the existing water supply/drain lines — whether they need rework.
- Whether the countertop needs to be re-cut for the new fixture.
- How difficult the work site is to access.
The prices above are for reference only. Actual cost depends on the site’s condition and will be finalized after an on-site survey.
On the Ho Chi Minh City market, reference pricing for lavabo or kitchen sink replacement labor typically runs a few hundred thousand VND per unit depending on complexity, not including the fixture itself or any additional materials. For an accurate quote for your specific project, we recommend booking an on-site survey.
Technical Notes for Lavabo/Kitchen Sink Replacement
A few small technical details have a big impact on how well-sealed and durable the fixture is after installation:
- Countertop cutout dimensions: each lavabo/sink model has different dimensions — switching to a model with a different size means the stone or kitchen countertop needs to be re-cut.
- The drain trap (P-trap): needs the correct type and a tight connection to prevent sewer odor coming back up and to prevent leaks.
- Waterproofing silicone around the edge: should always be replaced with a fresh application when installing a new fixture — never reuse old, degraded silicone, as it lets water seep into the countertop.
- Water supply pressure: should be checked to ensure the faucet works reliably, avoiding weak flow or leaks at the connection point.

Repair or Replace — Which Solution to Choose
Not every situation calls for a full replacement. The choice between repair and replacement should be based on the actual condition:
- Repair is the right call when the issue is limited to the faucet, trap, or rubber gasket — items that can be fixed quickly at low cost.
- Replacement is the right call when the lavabo/sink body is cracked, the leak persists despite repeated repairs, or you want to upgrade the style or material.
- An on-site survey is worth doing before deciding, since what looks like a fixture leak sometimes actually originates from the drain pipe below.
Bathroom Lavabo vs. Kitchen Sink Replacement — Key Differences
Although both are water-fixture replacement services, bathroom lavabos and kitchen sinks have a few notable technical differences:
| Criteria | Lavabo (Bathroom) | Kitchen Sink |
|---|---|---|
| Installation location | On a bathroom stone countertop, wall, or pedestal stand | On a kitchen countertop (stone, stainless steel), usually with cabinetry below |
| Basin size | Usually 1 basin, moderate size | 1 or 2 basins, larger to accommodate pots and pans |
| Waterproofing needs | Focused at the base and the edge meeting the countertop | Needed around the entire edge due to more frequent water contact |
| Accessories | Lavabo faucet, trap, mirror/shelf (if any) | Hot/cold kitchen faucet, trap, sometimes a water filter |
Should You Replace a Lavabo/Kitchen Sink Yourself
DIY lavabo or kitchen sink replacement carries real risk without experience:
- Cutting the countertop opening to the wrong size, which is hard to fix once done.
- An improperly sealed trap connection, causing leaks or sewer odor coming back up the drain.
- Incorrect waterproofing, leading to water seeping into kitchen or bathroom cabinetry over time.
- Incorrect faucet connection causing weak flow or leaks at the joint.
For anything involving countertop cutting and waterproofing, it’s best to have a qualified technician handle the work to avoid costly fixes later.
Maintaining Your Lavabo/Kitchen Sink After Replacement
After installation, a few simple maintenance habits help keep the fixture running reliably for the long term:
- Periodically check the waterproofed area around the edge, especially after 6–12 months of use.
- Clean regularly to prevent buildup — and grease for kitchen sinks — that reduces drainage efficiency.
- Avoid pouring thick grease or hard objects down the kitchen sink to prevent clogging the trap.
- Check the faucet and trap periodically to catch leaks early and avoid wasting water.
Preparing Before the Technician Arrives
To help the survey and replacement go smoothly, customers can prepare the following information and conditions in advance:
- Decide on the lavabo/sink type in advance (if already chosen), or describe your needs for tailored advice.
- Make sure the installation area is clear and easily accessible for the technician and equipment.
- Note the current condition (leaking, cracked, slow drainage, etc.) to help with an accurate diagnosis.
- Shut off the water supply valve at the installation point before the technician arrives to avoid unexpected issues.

Frequently Asked Questions
What’s included in lavabo/kitchen sink replacement service?
It includes a site survey, removing the old lavabo or kitchen sink, checking the water supply/drain lines, installing the new fixture, waterproofing around the installation point, connecting the faucet, and testing operation before handover.
When should I replace my lavabo or kitchen sink instead of repairing it?
Replace it when the fixture is cracked, badly yellowed, or has a persistent leak at the base or joint despite repeated repairs, or when you want to upgrade the style or material to better suit the space.
What’s the difference between an undermount and countertop lavabo?
An undermount lavabo is mounted beneath the stone countertop for a seamless look and easier cleaning; a countertop (drop-in) lavabo sits on top of the counter, is simpler to install, and usually costs less.
Should I choose a single-basin or double-basin kitchen sink?
A single-basin sink suits a small kitchen with limited space; a double-basin sink is more convenient when you need to wash and soak items at the same time, and works well for families who cook often.
How long does lavabo/kitchen sink replacement take?
When keeping the same installation position, replacement typically takes about 45–90 minutes. If the countertop needs re-cutting or the plumbing needs rework, it can take longer.
What determines the cost of lavabo/kitchen sink replacement?
Cost depends on the fixture type, material (ceramic, stone, stainless steel), the condition of the existing supply/drain lines, whether the countertop needs re-cutting, and how difficult the installation site is to access.
Should I replace a lavabo or kitchen sink myself?
Without experience, DIY replacement often leads to leaks at the base or joint, an incorrectly sized countertop cutout, or a poorly sealed trap connection. It’s best to have a qualified technician handle it.
Does replacing a kitchen sink require re-cutting the stone countertop?
If the new sink has the same size and shape as the old one, no re-cutting is needed. Re-cutting is only required when switching to a sink with a different size, shape, or basin position.
