Waterfall vs Hollywood Stair Runner Installation

Waterfall

The runner leaves the nosing and drops straight down to the back of the next tread, without following the curve of the step edge. It creates a soft, cascading line and is the faster of the two to fit.

Hollywood (wrapped or upholstered)

The runner is pulled tight around the nosing and pushed into the crease at the back of each tread, so it follows the exact profile of the staircase. It shows off the step shape, looks crisper, and is the traditional finish on period staircases.

How much extra material Hollywood needs

Budget roughly twice the nosing depth per step. On a 13-step staircase with a 1.25in nosing that is 32.5in — most of a metre. Forgetting it is the classic reason a wrapped installation runs short on the last step.

Which should you choose?

• Thick or high-pile runner: waterfall — thick pile will not wrap a nosing cleanly.
• Patterned runner: Hollywood — the pattern follows the step and reads correctly from below.
• Decorative or moulded nosings: Hollywood, to show the profile.
• Tight budget or DIY: waterfall, as it uses less material and is easier to get right.
• Open-riser staircase: waterfall is usually the only workable option.

Fitting time compared, step by step

Cost difference on a typical staircase

On a 13-step flight, the extra material for a Hollywood fit typically adds $40-90 / £32-72 depending on runner price per metre, and professional labour usually runs $2-6 / £1.60-4.80 more per step for the slower, more careful stapling. Add the two together and a wrapped installation on a mid-range runner commonly costs $150-300 / £120-240 more overall than the equivalent waterfall fit.

Can you switch from one method to the other later?

Not without re-fitting. A waterfall installation is cut and hemmed at the back of each tread with no allowance for wrapping the nosing, so converting to Hollywood later needs a longer runner and a full re-fit rather than an adjustment. If you are undecided, buy the extra length for Hollywood — a waterfall fit can always use less of a longer runner, but a Hollywood fit cannot stretch a runner cut short for waterfall.

How each looks on patterned versus plain runners

• Plain flatweave: either method works; waterfall is the more common default choice.
• Bold stripe or border pattern: Hollywood reads better because the pattern wraps the nosing and stays visually continuous.
• Herringbone or geometric weave: Hollywood shows off the weave direction changing at each step edge.
• Deep-pile plush: waterfall almost always, since thick pile bunches and distorts when wrapped tightly.

Regional naming and why it confuses buyers

US suppliers almost always use the terms waterfall and Hollywood, while UK fitters more often say straight-drop and wrapped or upholstered stair runner for the same two methods. If you are getting quotes from suppliers across regions, describe the physical method rather than relying on the name alone, since a miscommunication here is a common cause of a runner arriving with the wrong yardage.

Underlay and gripper differences between the two methods

Waterfall installs use a single thickness of underlay across the full tread and let the runner drop straight into the crease behind, so the underlay cut is simple and forgiving. A Hollywood fit needs the underlay to wrap the nosing along with the runner, which means either a pre-shaped stair pad or a fitter cutting and taping two pieces so the padding follows the same curve as the face fibre. Skipping this step is why some wrapped installations look slightly hollow right on the nosing edge within a year — the runner has nothing firm to be pulled tight against at the one point that gets the most flex.

How each method behaves on an open-riser or bullnose staircase

Open-riser stairs have no vertical timber for a Hollywood wrap to tuck behind, so waterfall is close to the only realistic option — the runner simply drops from one tread to the next in open air. A bullnose or curved bottom step causes the opposite problem: wrapping a tight radius in a Hollywood style takes real skill to pleat evenly, and many fitters will recommend stopping the runner on the tread above a bullnose rather than attempting a wrapped finish over the curve, whichever method is used on the rest of the flight.

Ordering checklist for each method

How much extra carpet each style uses

The difference is not stylistic only — it is measurable. A waterfall runner drops from the nosing straight to the next tread, so on a stair with a 1in nosing projection it saves roughly the depth of that projection on every step. A Hollywood runner is pulled tight into the junction of tread and riser, wrapping the nosing, which adds about 1 to 1.5in per step plus a little tension allowance. Over 14 steps that is 14 to 21in of extra carpet, or nearly two feet — enough to change which roll length you need to buy.

Which style suits which stair

Waterfall reads softer and is more forgiving on stairs where the risers are not perfectly consistent, because the loose drape hides a millimetre or two of variation. It is also the faster fit, which is why it dominates on budget and rental jobs. Hollywood shows the profile of every step and looks sharper on a well-built staircase with square nosings and consistent risers — but that same crispness advertises any inconsistency in the carpentry. On a bullnose bottom step or an open-sided flight, Hollywood is almost always the better choice because the wrap continues the line of the tread rather than cutting across it.

Durability and wear over time

Wear concentrates on the nosing in both styles, but the mechanism differs. Hollywood puts the carpet under tension across the nosing, so the pile is compressed and abrades evenly; waterfall leaves the carpet unsupported at that point, so it flexes with each footfall and can develop a crease line after a few years. On wool with a dense pile the difference is minor; on a low-density synthetic loop, waterfall fits tend to show a visible fold on the nosing sooner. If you are choosing waterfall, spend the saving on a denser pad rather than a cheaper carpet.
