Kitchen Sink Replacement in Belgium
A cracked, stained, or leaking sink can quickly cause hidden water damage to your kitchen cabinets and countertops. A professional sink replacement restores reliable drainage, a solid tap fitting, and a long-lasting watertight seal around your worktop.
Whether you are replacing a stainless steel, ceramic, or composite granite basin, careful verification of existing cut-out dimensions, countertop structure, and under-sink plumbing is essential. Send photos of your current sink and the pipework beneath with your Belgian postal code or commune for an initial assessment.

When to replace your kitchen sink
Cracked or chipped basin
Impact damage on ceramic or composite basins can cause persistent hairline leaks into the base cabinet below.
Countertop moisture damage
Failed silicone seals allow dishwashing water to seep under laminate worktops, causing the core material to swell and rot.
Outdated or leaking pipework
Corroded drain connections, misaligned traps, or lack of proper appliance connections for a new dishwasher.
Kitchen renovation & upgrade
Upgrading to a deep stainless steel or composite undermount basin with a pull-out spray mixer for improved ergonomics.
Professional fitting & plumbing connection
Replacing a sink involves more than dropping a basin into a hole. We carefully disconnect water supplies and drain pipes, remove the old unit without damaging surrounding cabinets, clean away old sealants, and test the structural support.
We connect hot and cold supply flexible lines to angle shut-off valves, fit the tap securely, install the waste strainer and overflow kit, and assemble an odor-free trap with dedicated dishwasher discharge if needed.
Countertop cut-out considerations
On laminate or solid wood worktops, small adjustments or enlargements to the existing cut-out are relatively straightforward. On granite, marble, or engineered quartz, altering the cut-out on-site is difficult and risky, meaning the replacement sink must match existing cutout specifications precisely.
We help you verify dimensions before fitting to ensure a clean, flush, and secure installation.
Safe checks before booking a plumber
You can carry out a few safe checks to help prepare the replacement:
- Test whether the small shut-off valves under the sink turn smoothly without force.
- Measure the outer dimensions of your sink and note bowl depth.
- Inspect under the cabinet with a flashlight to see if water stains are active.
- Take clear pictures showing both the top basin and the plumbing underneath.
- Never use excessive force on stiff valves, which can snap and cause a flood.
When to call an experienced plumber
- Active water pooling inside the kitchen cabinet beneath the sink.
- The waste trap or drain pipe is cracked, leaking, or improperly aligned.
- The mixer tap is loose, corroded, or seized to the sink body.
- You need a new sink installed and plumbed in compliance with Belgian standards.
- You want a clean, professional silicone bead to protect your kitchen worktop.
Step-by-step sink replacement workflow
The job starts by shutting off the local water supply and isolating the circuit. The old sink, strainer basket, siphon, and tapware are disconnected and extracted cleanly. Old silicone residue is thoroughly removed and the cut-out edge is inspected and sealed against moisture.
The new basin is positioned with heavy-duty mounting clips and high-grade sanitary silicone. We hook up the tapware, connect the waste trap, and run thorough high-volume drainage and standing-water pressure tests to verify 100% leak-free performance before leaving.
Kitchen sink replacement pricing factors
Pricing depends on the mounting method (inset drop-in vs undermount), whether worktop cut-out adjustments are needed, the condition of the angle isolation valves, and any modifications required for the drain pipework.
We do not publish misleading flat fees because every kitchen setup differs. To receive an accurate estimate, send us your commune, photos of the top and bottom of your sink, and details of your planned replacement unit.
Tenants, landlords and property managers
In Belgium, minor washer replacements and regular cleaning are tenant responsibilities, while replacing a broken, heavily worn, or damaged fixture typically falls under the landlord’s remit. If you are renting, please confirm landlord approval prior to replacement.
In apartment buildings, unaddressed under-sink leaks can seep through floorboards and damage neighboring units below. Prompt replacement protects your deposit and the building fabric.

Frequently Asked Questions — Sink Replacement
Can I replace my sink without replacing the entire countertop?
Yes, in most cases. You simply need to select a replacement sink with outer and cut-out dimensions that match or slightly exceed the existing opening.
Can I keep my current kitchen tap?
Yes, if the tap is in good working condition and fits standard 35mm tap holes. We will reinstall it with fresh sealing washers and flexible hoses if needed.
How long does a typical sink replacement take?
A standard replacement typically takes between 1.5 to 3 hours depending on how easily the old unit is removed and whether drain lines need reconfiguration.
Can you connect my dishwasher to the new sink drain?
Yes, we fit a siphon with an integrated appliance drain nozzle and anti-backflow valve specifically designed for dishwasher discharge.
What sealant is used around the sink edges?
We use professional-grade anti-mold sanitary silicone designed for high-humidity kitchen and bathroom environments.
