Bathroom Vanity, Toilet and Faucet Replacement
Swapping a vanity, faucet, toilet or light fixture is the quick way to refresh a bathroom without a remodel. A like-for-like vanity replacement on existing plumbing can be done in a day. The price grows when the sink moves, the wall needs repair behind the old unit, or a wall-mounted design needs new framing.

Before ordering, measure the old vanity width, depth and the position of the drain and supply lines. A new vanity that is deeper than the old one can block a door or crowd the toilet. Faucet holes in the top must match the faucet you buy, which is a common mistake when the two are bought separately.
Replacing the shut-off valves and supply lines at the same time is cheap insurance. Old valves often seize or leak when they are turned for the first time in years.
What the work includes
- Removal of the old vanity, top and sink, with disposal
- Shut-off valves, supply lines and drain trap replaced where needed
- Setting the new vanity level and fixing it to the wall
- Countertop, sink and faucet installation with sealant
- Toilet removal and reinstallation, with a new wax ring or seal
- Mirror, medicine cabinet or light fixture mounting
- Blocking installed inside the wall for wall-hung units
- Wall touch-up and caulking at the splash

Signs it is time to replace the vanity or fixtures
The cabinet floor is swollen or soft from slow leaks under the sink
The top is stained, cracked or the sink has chipped
The faucet drips or the handles are loose and corroded
The toilet rocks, runs constantly or leaks at the base
A fixture style you dislike but the rest of the bathroom is fine
There is too little storage, or the vanity is too low or too high for the people using it

- Plumbing position
- Moving the drain or supply to a new spot means opening the wall or floor.
- Countertop material
- Cultured marble, quartz and stone tops differ in price and installation.
- Fixture quality
- Faucets and toilets range widely, and special valves or wall-mounted designs need more work.

Vanities & Fixtures: questions people ask
Can a bathroom vanity be replaced without a plumber?
Many people do, but leaking connections and unlevel cabinets are common problems. If the drain or supply has to move, a plumber is the safer route.
Why do faucet and sink holes need to match?
Faucets come in single-hole and three-hole formats. Buying the faucet and top together, or checking the spec sheet, avoids drilling mistakes in stone.
How long does it take?
A like-for-like vanity and faucet swap is usually a day. Adding a toilet, a new mirror or wall repairs can extend it.
Should the toilet be replaced when the vanity is?
It is an easy time to do it, since the room is already open. A new seal under an existing toilet is the minimum, and a rocking toilet should be fixed.
