If you have fallen in love with a freestanding tub, the next question is almost always the same: where does the faucet go, and how high, how far, and what type should I choose? This guide answers those questions in plain, practical language from a contractor style point of view, with clear rules of thumb, pro tips, and example layouts you can actually use.
Below you will find a quick reference, then a deeper dive into installation, valve choices, faucet types, placement math, code minded details, common mistakes, and an FAQ.
Short answer
Use these quick rules to get in the ballpark before you fine tune:
-
Choose the mounting style first. Freestanding floor filler, wall mount, or deck mount on the tub rim or ledge.
-
Center the spout over the tub basin where it will pour into water, not onto the rim. For most tubs, the spout outlet should land 2 to 4 in inside the inner edge of the tub.
-
Spout height relative to the tub rim: about 4 to 6 in above the rim for wall or deck outlets, or follow the faucet manufacturer spec for floor fillers. Many floor fillers put the spout outlet 32 to 44 in above finished floor.
-
Horizontal offset from the drain and overflow: do not aim the spout directly at the overflow opening. Offset a few inches for quieter filling and less splash.
-
For floor fillers, rough in hot and cold supplies 6 to 8 in apart on center, 3 to 4 in away from the tub footprint, and centered on the intended spout location. Always confirm with the faucet rough in sheet.
-
Always include an anti scald mixing valve. For a hand shower, include a diverter and a backflow device per the faucet kit.
Once those basics are right, you can adjust for your tub shape, room layout, and how you plan to bathe.
Why people in the U.S. love freestanding tubs
-
Design flexibility
A freestanding tub can stand in front of a window, anchor the center of a large bathroom, or tuck into a cozy alcove. It reads like furniture, not a built in fixture. -
Easier remodel sequencing
You can finish floors and walls first, then set the tub. There is no apron or tiled deck to build. -
Resale appeal
In many markets, a statement tub is a selling point in primary baths. It photographs well and signals a higher end remodel. -
Maintenance
There are no tub deck grout joints to maintain. If you keep access to the supplies and drain, future service is straightforward.
How to install a freestanding tub, step by step
This is the high level sequence pros follow. Your tub and faucet instructions always take priority, but the flow below will help you avoid headaches.
-
Confirm floor structure and weight
A cast iron tub full of water plus a bather can exceed 800 pounds. Verify framing and subfloor are up to the load. -
Plan the drain and overflow
Most freestanding tubs use a waste and overflow kit that connects through the floor. Dry fit the trap, measure centerlines, and confirm the tub outlet location. -
Choose the faucet type and rough in now
Decide on floor mount, wall mount, or deck mount before closing the floor or wall. Pull hot and cold supplies, set blocking for valves, and position the rough in based on the faucet spec sheet. -
Finish surfaces to final thickness
Tile, stone, or wood thickness changes the final offset. Do not set the tub or the faucet until finished surfaces are in place. -
Set the tub
Level the feet or base, apply any required support pad, and test fit the drain and overflow. -
Mount and connect the faucet
Align to the layout marks, secure through the floor or into wall blocking, and make final connections per the manufacturer. -
Pressure test and splash test
Check for leaks. Then fill the tub halfway, open the faucet at typical pressure, and watch for splash or dribble on the rim. Adjust angle and flow limiters if needed.
How to choose the right faucet for a freestanding tub
There are three mainstream choices. Pick based on look, plumbing path, and serviceability.
1) Freestanding floor mounted tub filler
-
The look: a sculptural column with a tall spout and often a hand shower.
-
When to use: open floor plan layouts, window walls, or where walls are far from the tub.
-
Why pros like it: easiest to place exactly where you want the water to land, without opening finished walls.
-
Watch outs: needs a sturdy floor mounting bracket and a precise rough in. The price is usually higher than other options.
2) Wall mounted tub spout and valve
-
The look: clean and minimal. Works well with modern or transitional bathrooms.
-
When to use: tub near a framed wall with accessible plumbing.
-
Why pros like it: all piping stays in the wall, which may simplify the floor and avoids holes in the finished floor.
-
Watch outs: requires solid blocking for the valve and spout, plus careful height setting. Adds splash risk if the wall is too far from the tub edge or if the spout is too short.
3) Deck mounted roman tub or bridge faucet on the tub rim or ledge
-
The look: classic. Handles and spout mounted on the rim or on a nearby ledge or shelf.
-
When to use: tubs with a wide, flat rim or when you are building a small shelf adjacent to the tub.
-
Why pros like it: short water path, strong flow, comfortable control placement.
-
Watch outs: not all freestanding tubs have a rim wide enough, and drilling the tub often voids the warranty unless the tub is designed for deck mounting.
Where should a faucet be placed for a freestanding tub
Use this placement framework, then confirm against your faucet and tub specifications.
Step 1: Choose the landing point for the water stream
-
Goal: water falls inside the basin without hitting the rim or the far wall of the tub.
-
Rule of thumb: center the water stream 2 to 4 in inside the inner edge of the tub at the chosen pour point.
-
Avoid: pouring directly onto the overflow hardware. Offset the stream at least a couple of inches left or right to reduce noise and aeration.
Step 2: Set spout height
-
Wall mount or deck mount spout outlet: typically 4 to 6 in above the tub rim. This gives hand clearance for cleaning and reduces splash.
-
Floor mounted tub filler outlet: follow the faucet spec. Common spout outlet heights are 32 to 44 in above finished floor. Your tub rim may be 22 to 24 in high, so this keeps the outlet roughly 8 to 20 in above the rim depending on the fixture style.
Step 3: Align controls where your hand naturally reaches
-
For floor fillers with side handle: set the handle to face the main entry side of the bathroom, not the wall.
-
For wall valves: 6 to 12 in above the rim feels natural when seated in the tub. If you plan to start the water while standing outside, consider 36 to 42 in above the floor.
Step 4: Rough in horizontal location for each mounting type
-
Floor mounted filler
-
Supply stubs on center 6 to 8 in apart.
-
Place the centerline of the filler 3 to 4 in away from the nearest tub edge, measured to the outside of the tub footprint.
-
Center the filler on the chosen pour point. Many designs put the spout near the middle of the tub length, slightly toward the drain end to avoid the overflow.
-
-
Wall mounted spout
-
Keep the spout as close as practical to the tub to minimize fall distance. Commonly the spout face ends up 1 to 3 in from the tub rim at rest.
-
If a deep ledge or window sill sits behind the tub, extend the spout enough to clear it and still pour 2 to 4 in inside the tub.
-
-
Deck mounted
-
Confirm the tub is drilled for a deck set or is rated for field drilling.
-
Space holes per faucet template, usually 8 to 12 in on center for widespread sets.
-
Aim the spout outlet toward the basin centerline, with the outlet 4 to 6 in above the rim.
-
Example placement math
Imagine a 60 in long by 30 in wide slipper tub. The rim sits 23 in above the floor. You choose a floor mounted filler with a spec that puts the spout outlet at 38 in above the floor and 6 in in front of the column centerline.
-
Vertical: spout outlet 38 minus rim 23 equals 15 in above rim, which is within the common range for fillers.
-
Horizontal: place the column centerline 3.5 in outside the outer rim. With a 1 in rim thickness and a soft curve, that puts the spout outlet about 3.5 plus 1 equals 4.5 in outside the inner edge. The outlet itself is 6 in in front of the column, so the water stream lands roughly 1.5 in inside the inner edge. Nudge the column 0.5 in closer and you hit the 2 in target cleanly.
Now imagine a wall mount behind an oval tub with a 2 in ledge behind it. The spout needs to clear 2 in plus a 1 in gap to avoid touching, so you need a spout reach of at least 3 in past the finished wall to the rim, plus 2 in inside the inner edge. If the rim thickness is 1.5 in, total reach is 3 plus 1.5 plus 2 equals 6.5 in minimum. Choose a spout with 7 to 8 in reach so you can fine tune.
Can you use a wall mounted faucet with a freestanding tub
Yes, and it can look fantastic. Keep these points in mind:
-
Structure and blocking
Place solid wood blocking in the wall for both the mixing valve and the spout to prevent wobble when you turn handles. -
Reach
Pick a spout with enough projection to land the stream 2 to 4 in inside the inner edge of the tub. Many standard wall spouts designed for sinks are too short. Look for tub rated spouts in the 6 to 10 in projection range. -
Splash management
The higher the spout, the more it splashes. Keep the drop from spout to water line reasonable. If you plan to run the spout while the tub is empty, keep the outlet lower relative to the rim. -
Service access
A wall valve is easier to service when you have a closet or cabinet behind it. If not, plan a decorative access panel on the opposite side of the wall if possible.
Does a freestanding tub faucet need a valve
Yes. You always need a mixing valve that delivers tempered water safely and consistently. There are two common types:
-
Pressure balance valve
Maintains the ratio of hot to cold when pressure changes. Good baseline scald protection. Simple and cost effective. -
Thermostatic valve
Sets and maintains an exact temperature by sensing water temp, not just pressure. Offers higher flow potential for faster fills and a more stable bath temperature, but costs more.
If your faucet includes a hand shower, you also need a diverter to switch water from the spout to the hand shower and an integrated backflow preventer to protect the potable supply. Most reputable tub filler kits include these components, but verify they are listed for tub use and meet U.S. standards.
How are tub faucets installed
The process varies by mounting style. Here is the pro level overview so you can plan rough in, tools, and inspection.
Floor mounted freestanding tub filler
-
Layout
Mark the tub footprint, the spout landing point, and the centerline of the filler. -
Bracket and blocking
Anchor the floor bracket to framing or concrete with appropriate fasteners. The bracket prevents wobble. -
Rough in supplies
Bring hot and cold up through the floor to the bracket. Cap and pressure test. Typical spacing is 6 to 8 in on center, but follow the faucet spec. -
Set finished flooring
Cut tight around the bracket and supply stubs. -
Mount the column
Slide the filler body over the bracket, secure set screws, and connect to the supplies with the manufacturer fittings. -
Connect hand shower and test
Check for leaks at full hot and full cold. Test the diverter and confirm the check valve is present.
Wall mounted spout and valve
-
Open stud bay
Install blocking at valve and spout height. Set the valve depth using the included plaster guard. -
Rough in piping
Run hot and cold to the valve, then from the valve to the spout and diverter if included. Cap and test. -
Close wall and finish surfaces
Tile or wall finish must account for final valve depth so trim sits flush. -
Install trim and spout
Use thread sealant or manufacturer gasket. The spout should be solid with no play. -
Function test
Check temperature control, flow rate, and splash.
Deck mounted on tub rim or ledge
-
Confirm drill locations
Use the faucet template. Verify the tub manufacturer allows drilling and the rim is thick enough. -
Drill holes
Use the correct hole saw for the material: carbide or diamond for acrylic and stone resin, step bit for metal. -
Set valves and spout
Install mounting hardware and gaskets, then connect hoses per the faucet instructions. -
Connect to supplies
If on a ledge, bring supplies up through the deck. If on the rim, connect flexible hoses below the tub and provide an access point for service. -
Test for leaks and splash
Run full flow and verify the stream lands well inside the basin.
Why are freestanding tub faucets so expensive
-
Materials and weight
A quality tub filler is mostly brass with thick wall tubing. It has to be rigid at full height and flow a lot of water without whistling. -
Flow capacity
Filling a deep tub quickly takes more water. High flow cartridges, larger valve ports, and larger internal passages add cost. -
Stability hardware
Floor brackets, anti wobble plates, and heavy escutcheons are part of the kit. -
Finishes and listing
Durable finishes like PVD and compliant listings to U.S. plumbing standards increase manufacturing cost. -
Low volume, high design
Tub fillers sell in lower volumes than standard faucets, and many are design forward pieces. That affects pricing.
If you are on a tighter budget, consider a wall mount set. You get strong performance with fewer parts and a lower price, provided your layout allows it.

Real world examples you can copy
Example A: Compact bathroom with tub near a side wall
-
Tub: 55 by 28 in compact oval, rim height 22 in.
-
Faucet: Wall mount with 7.5 in spout reach.
-
Placement: Spout outlet 27 in above floor, which is 5 in above rim. Spout centerline set 2.5 in inside the inner edge. Valve handle at 36 in above floor for easy reach when standing outside the tub.
-
Notes: Tub is 3 in off the wall to allow cleaning. A long reach spout clears the gap and still lands inside the basin.
Example B: Large primary bath, tub centered under a window
-
Tub: 66 by 32 in slipper, rim height 23 in.
-
Faucet: Floor mounted filler, spout outlet 40 in above floor.
-
Placement: Column centerline 3.25 in outside the tub rim. Supplies 7 in on center. Spout landing 3 in inside the inner edge, offset 4 in from the overflow centerline.
-
Notes: The handle faces the room entry. A floor bracket is lagged into joists for rock solid stability.
Example C: Deck mount on a small ledge behind the tub
-
Tub: 60 by 30 in modern rectangle, rim height 23 in.
-
Faucet: Widespread roman tub faucet with hand shower.
-
Placement: Spout outlet 5 in above rim on a 7 in deep ledge. Controls 8 in on center. Access panel behind the ledge for servicing hoses and valves.
-
Notes: The ledge doubles as a shelf for bath items and simplifies plumbing.
Code minded details without the legalese
-
Anti scald protection
Use a listed pressure balance or thermostatic mixing valve. Set the maximum temperature stop per the instructions. -
Backflow protection
Hand showers should include a check valve or vacuum breaker to prevent cross contamination. -
Access for service
If valves or connections are concealed inside a wall or a built ledge, provide a way to access them later. -
Slippery floors and splash
Keep spout height reasonable and landing point inside the basin. If you see splash on the rim during testing, lower flow slightly or nudge the spout inward. -
Structural support
Floor fillers must be anchored to framing or set with manufacturer approved anchors in concrete. Wall valves and spouts need blocking.
If you are pulling a permit, your local inspector may have preferences. Bring the faucet spec sheets to your inspection.
Choosing flow and sizing your water heater
Freestanding tubs usually hold more water than standard alcove tubs. Plan for fill time and hot water supply.
-
Typical tub capacities
Many freestanding tubs hold 55 to 80 gallons to the overflow. The comfortable bathing volume is usually 60 to 70 percent of the max. -
Desired fill time
A 10 minute target is common. At 6 gallons per minute you can put 60 gallons in 10 minutes. Many high quality fillers flow 6 to 10 gpm depending on your home pressure and piping. -
Water heater check
If you like a hot soak, verify your heater and recirculation can keep up. A 50 gallon tank at 140 F mixed down to 105 F delivers more usable hot water than the same tank at 120 F, but be sure your mixing valves are set correctly to avoid scald risk.
Common mistakes and how to avoid them
-
Spout too short
The water hits the rim or the outside of the tub. Fix by choosing a longer reach spout or moving the mount closer. -
Spout too high
The stream splashes loudly and sprays beyond the tub when empty. Lower the outlet or reduce flow. -
No access for service
Valves buried without an access panel turn a simple cartridge swap into a wall repair. Plan an access route from the start. -
Floor filler wobble
The column flexes because the bracket is not anchored into solid framing. Use the correct bracket and fasteners. -
Misaligned with the tub
The spout does not land where intended because finished tile thickness was not accounted for. Dry fit with finished surfaces in place before final drilling and anchoring. -
Forgetting the hand shower backflow device
Most kits include it, but double check. It is a must have for safety and compliance.

FAQ
Q1:Where exactly should I center the faucet relative to the tub length
A:There is no single correct answer. Many designs center the filler near the middle of the tub length for symmetry. Others place it near the drain end so you can sit away from the stream while filling. Pick based on how you bathe and your tub shape, then center the spout over a part of the basin that is not directly above the overflow.
Q2:How high should a floor mounted tub filler be
A:Follow the manufacturer specification. Most spouts sit between 32 and 44 in above the floor. The result is typically 8 to 20 in above the rim depending on tub height and style.
Q3:How far should the spout reach into the tub
A:Plan for the stream to land 2 to 4 in inside the inner edge of the tub. Too close to the rim causes splash and streaking. Too far risks hitting the far wall of the tub.
Q4:Can I put a freestanding tub against a wall and still use a floor filler
A:Yes. Keep a small cleaning gap, often 2 to 3 in, between the tub and wall. Place the floor filler column in that gap, but ensure you still have room to clean and service.
Q5:Do I need a special valve for a hand shower
A:You need a diverter to route water from the spout to the hand shower, and a built in backflow device. Many tub filler kits include both. Verify in the specs.
Q6:Will a wall mount faucet splash more than a floor filler
A:It can if the drop is high or the reach is short. Keep the outlet a few inches above the rim and aim for a landing point inside the basin. Test at your typical pressure and adjust.
Q7:Can I drill holes in an acrylic or stone resin freestanding tub for a deck mount
A:Only if the manufacturer explicitly allows it. Use their template and tools. Drilling a tub not rated for deck mounting can void the warranty.
Q8:How fast should a tub faucet fill
A:Aim for 6 to 10 gpm at typical residential pressure. Faster fills are nice, but only if your water heater and piping can support the flow without major pressure drops elsewhere in the home.
Q9:What if my tub has a very narrow rim
A:Use a floor mounted filler or a wall mounted spout. Deck mounts need a wide, flat surface with enough material thickness to hold the mounting hardware.
Q10:Do I need shutoff stops at the faucet
A:It is good practice. Many valves include integral stops so you can service the faucet without shutting water to the whole house. If yours does not, install accessible stops on the supply lines.
