How to Install a Freestanding Bathtub
Part of our Bathtubs guides.
Setting the tub is straightforward; the drain and filler plumbing usually need a plumber. Turn off the water (and power at the breaker for anything electrical) before starting, and follow the product manual where it differs from these general steps.

Step by step
- Plan drain and filler. Mark the drain hole location and the filler's supply lines.
- Rough-in plumbing. Run drain and supply lines through the floor (plumber).
- Install filler. Bolt the floor-mount filler base to the subfloor.
- Connect drain. Attach the tub's drain and overflow to the floor drain.
- Set and level. Lower the tub into place with a helper; adjust feet to level.
- Test. Fill to the overflow and check for leaks.
- Seal. Run silicone around the base if recommended.
Tips & common mistakes
- Confirm floor load capacity on upper floors.
- Leave access to the drain if possible.
Planning the drain location
Unbox the tub and measure the drain position from its edges, or use the template in the manual. Mark the floor where the tub will sit and where the drain will land. Check the joist direction below: the drain should fall between joists, not on one. If it lands on a joist, shift the tub slightly or consult a contractor about reinforcing.
Choosing the filler
- Floor-mount filler: the classic look; needs supply lines coming up through the floor and solid blocking to bolt to.
- Wall-mount spout: only works if the tub sits close to a wall with a valve.
- Deck-mount: only on tubs with a faucet ledge.
VEVOR's floor-mount filler includes a handheld, which helps with rinsing hair and cleaning the tub.
Leveling and stability
Most acrylic freestanding tubs have a flat base or adjustable feet. Check level across both directions. A tub that rocks will stress the drain connection and can crack; shim or adjust until it's solid.
Access for future repairs
If there's a basement or crawlspace below, you'll have easy access to the drain. On a slab, the connection is buried, so test thoroughly before finishing the floor around it.
