Pool water feature design is where a pool moves from a body of water to something more alive. The sound of moving water changes the character of an outdoor space in a way that no other design element produces. It creates a sense of presence and activity even when no one is swimming. It masks background noise. It makes a pool area feel more like a place — somewhere designed with intent — rather than simply a pool in a backyard.
The options for pool water features range from simple and elegant to complex and theatrical. Understanding what each type delivers — visually, acoustically and in terms of cost — makes the selection process straightforward.
Pool Water Feature Design: The Main Categories
Blade Features
A blade water feature is a horizontal slot or opening — typically in a raised wall or bond beam — through which water flows in a thin, controlled sheet into the pool below. The water falls as a smooth, unbroken plane — a blade of water — that produces a clean visual effect and a consistent, gentle sound.
Blade features are the most architecturally restrained water feature available. They suit contemporary and minimalist pool designs where the design language is precise and controlled. In a dark-water pool with a feature wall behind it, a blade feature produces an effect that is genuinely difficult to improve on.
The sound of a blade feature is specific — a clean, consistent white-noise that is present without being dominant. At a single blade, it is subtle. Multiple blades, or a wider aperture, increase the volume proportionally.
Cost: A single stainless steel blade feature, including the housing, plumbing and installation, typically costs $1,500 to $4,000 depending on the width and the complexity of the wall integration.
Spillway Features
A spillway is a slightly wider, more generous water flow than a blade — water that spills over a horizontal edge into the pool rather than emerging from a slot. The effect is fuller than a blade, with more movement and slightly more sound.
Spillways are available in stainless steel, stone, concrete and ceramic tile finishes. The material can be selected to match or complement the pool coping or the feature wall material.
A spillway integrated into the top of a raised spa wall — cascading from the spa level into the pool below — is one of the most common and effective water feature configurations in Queensland pool design. The spa and pool are connected visually and acoustically. The spillway adds movement and the sound of flowing water to both spaces simultaneously.
Cost: A standard spillway, including housing and installation, typically costs $2,000 to $5,000. Integrated spa-to-pool spillways are typically included in the spa construction cost.
Scuppers
A scupper is a projecting spout — typically stainless steel, copper or ceramic — through which water flows into the pool in a parabolic arc. Multiple scuppers along a feature wall create a row of arcing water jets that are visually playful and acoustically rich.
Scuppers suit pool designs with a more expressive, feature-oriented aesthetic — they're less restrained than blades and spillways, and more visually active. In the right setting — a resort-style pool, a lagoon pool, a playful family pool — a row of scuppers creates a feature that pool users interact with and that animates the pool area in a way that more minimal features don't.
Cost: Scupper units typically cost $400 to $800 each. A row of three to five scuppers in a feature wall, including plumbing and installation, can typically cost ~$5,000 to $12,000.
Deck Jets
Deck jets are small nozzles set into the pool coping or surrounding paving that shoot laminar — glasslike, perfectly smooth — streams of water into the pool in an arc. The streams are clear and undistorted. At night, with LED colour lighting directed through the streams, they produce an effect that is genuinely spectacular.
Deck jets are interactive — pool users can run their hands through the streams, the arcs can be adjusted in height and distance. They suit family pools and resort-style designs where the water feature is intended to be part of the pool experience rather than simply a visual element viewed from the entertaining area.
Cost: Deck jet units typically cost $400 to $700 each. A set of four to six deck jets, including plumbing and installation, typically costs $4,000 to $10,000.
Waterfall Features
Waterfall features — from naturalistic rock waterfalls to architectural sheet waterfalls — are the most dramatic pool water feature option. They produce the most sound, the most visual movement and the strongest sense of presence.
Naturalistic rock waterfalls suit lagoon pool designs and resort-style pools where the overall aesthetic is organic and tropical. The construction involves building up a rock formation — typically using rendered concrete and real or artificial stone — with water pumped to the top and cascading over the rocks into the pool. The visual and acoustic effect is genuinely evocative of a natural environment. The construction is complex and the result is difficult to do subtly — a rock waterfall is a dominant feature that the pool design should be built around.
Architectural sheet waterfalls — a wide flow of water over a smooth vertical surface, typically tile or stone — suit contemporary pool designs where the feature is dramatic but controlled. The water flows as a thin, even sheet over a feature wall, catches the light and falls into a receiving channel or directly into the pool. The effect is bold and architectural.
Cost: Rock waterfall features vary enormously — from $8,000 to $50,000 or more depending on scale and complexity. Architectural sheet waterfalls, including the feature wall, waterproofing, pump system and installation, typically cost $10,000 to $40,000.
Sheer Descent Features
A sheer descent is a long, continuous blade feature — typically 300 to 900mm wide — that produces a wide, even sheet of falling water. It is a larger version of a blade feature, and the visual effect is proportionally more dramatic.
Multiple sheer descents across a feature wall create a screen of falling water that is visually compelling from a distance and creates a distinctive acoustic environment. Behind a sheer descent — looking out through the falling water — the visual effect is genuinely striking.
Cost: A standard sheer descent unit, including housing and installation, typically costs $2,500 to $6,000 depending on width.
Designing Water Features Into the Pool — Not Onto It
The principle that applies to all pool water features is the same one that applies to luxury pool design generally: features that are designed into the pool from the beginning produce better results than features added after construction.
A blade feature integrated into a rendered feature wall during pool construction is structurally part of the wall — the housing is built in, the plumbing is run before the wall is rendered, the finished surface conceals the infrastructure entirely. A blade feature added to an existing wall after construction requires surface-mounted housing and visible plumbing runs that undermine the visual precision the feature is intended to produce.
The same applies to all feature types. The earlier in the design process the water features are decided, the better the outcome.
Lighting and Water Features
Pool water features are transformed at night by lighting. LED lights — positioned to direct light through moving water — produce effects that daylight cannot replicate. A blade feature with an LED uplight behind it glows as the water falls. Deck jets with colour-changing LED lighting produce arcs of coloured light that move and shimmer. A rock waterfall with concealed spotlighting creates a dramatic nocturnal focal point.
If water features are being included in the pool design, lighting for those features should be specified at the same time. The two elements work together — neither is fully realised without the other.
What Does Pool Water Feature Design Add to Cost?
Water features add to both upfront construction cost and ongoing running cost. Each feature requires a dedicated pump — or shares pump capacity with the main circulation system — that runs when the feature is in use. Electricity costs for water features are modest in isolation but accumulate with use.
As a very general guide:
Feature Type | Approximate Installed Cost |
Single blade feature | $1,500 – $4,000 |
Spillway (standard) | $2,000 – $5,000 |
Scuppers (set of 4) | $5,000 – $12,000 |
Deck jets (set of 4-6) | $4,000 – $10,000 |
Sheer descent | $2,500 – $6,000 |
Rock waterfall (modest) | $8,000 – $20,000 |
Rock waterfall (elaborate) | $20,000 – $50,000+ |
Architectural sheet waterfall | $10,000 – $40,000 |
