Supply connection compatibility is a plumbing question, not a styling question. Before ordering a faucet, compare the exact product specification with the local supply setup and ask a qualified installer to confirm any adapters, shutoff valves or connection changes required for the project.
What to measure or confirm
- Identify the existing hot and cold supply locations beneath or behind the fixture.
- Review the connection information supplied for the exact faucet model.
- Confirm local pipe, thread and plumbing requirements with a qualified installer.
- Check that shutoff valves remain accessible after the vanity, sink and faucet are installed.
How to use the measurements
Do not assume a connection is universal because two fittings look similar. Compatibility can vary by market, product configuration and existing plumbing.
Common planning mistakes
- Ordering adapters only after the faucet has arrived.
- Ignoring restricted service space inside a vanity.
- Changing a connection plan without confirming it with the installer.
Before you order
Compare the finished project measurements with the specifications for the exact fixture you intend to buy. Where plumbing, mounting or connection work is involved, confirm the installation approach with a qualified professional before cutting stone, drilling a sink or closing a wall.
