The details people remember.
A pool is water; a great pool is an experience. The warmth of a raised spa, the hush of a sheet-fall, the glow of a grotto at night — these are the moments your family will gather around for years. They are also what separates a custom J. Oliver pool from a builder-grade rectangle.
We design each feature for its sound, its movement, and its light, then engineer the flow and plumbing so it runs quietly, efficiently, and exactly the way you imagined. Whether you are building a new pool or adding to one you already love, the right feature transforms how the whole backyard feels.
Water features are as much about engineering as aesthetics. The sound of a spillway depends on its flow rate, drop height, and weir style; the look of a sheet-fall depends on the precision of the lip it pours from; a spa that spills cleanly into the pool depends on careful elevation and plumbing. Get those details right and the feature feels effortless. Get them wrong and you end up with a noisy pump, an uneven sheet, or a spillway that splashes the deck. This is exactly the kind of detail work where an experienced custom builder earns its keep.
Every feature we build is tied into smart automation from partners like Pentair and Jandy, so you can heat the spa, start the waterfall, and set the lighting from your phone — and run each feature only when you want it, keeping operating costs low.
Adding a spa or water feature is also one of the most popular requests we get from pool renovation clients, which is why homeowners searching for a top pool builder or a pool builder near me trust us with both new builds and upgrades.
Raised & Attached Spas
Elevated, attached spas and built-in hot tubs that spill into the pool and seat the whole family.

Clean sheets of water and scuppers that carry sound to the patio.
Grottos, Waterfalls & Slides
Natural rock waterfalls and grottos with built-in pool slides for the whole family.
Tanning Ledges & Baja Shelves
Shallow sun shelves — also called Baja shelves or tanning ledges — for loungers, bubblers, and toddlers.
Deck Jets & Laminar Jets
Playful bubblers plus arcing deck jets and crystal-clear laminar jets that glow at night.
Fire & Water
Fire bowls and fire-and-water features for drama after dark.
LED Lighting & Automation
Color LED pool lighting and smart pool automation you run from your phone.
Pool Heating
High-efficiency heaters and chillers that keep the spa and pool comfortable year-round.
A glass orb, glowing from within.
The PAL Pool Water Sphere sits over flowing water and glows from below, lit by a PAL Lighting bubbler luminaire built into the feature. Water rises and shimmers inside the glass while the sphere catches color and light after dark.
Spheres are available from 12" to 32", so we can size one for a spa spillway, a raised wall, or a standalone accent basin, and pair it with glass or iridescent tile for a feature that reads as sculpture in daylight and light in the evening.
More on how one is built: what it takes to plumb, light, and place a PAL WaterSphere in a New Braunfels or Hill Country pool.
The features that define a custom pool.
Most signature backyards combine two or three of these. Here is how we think about each one — what it adds, how it sounds, and where it works best.
Raised spas
An elevated spa that spills into the pool adds warmth, a focal point, and year-round use. Clad in glass mosaic or stone, it becomes the visual anchor of the whole backyard — and the spot the family gathers on cool evenings.
Spillways, sheet-falls & scuppers
Smooth ribbons or arcing spouts of water that carry sound across the patio and catch the light. We tune flow, drop height, and weir style so the effect is exactly as loud, soft, modern, or playful as you want.
Grottos & rock waterfalls
Hand-built natural rock waterfalls and grottos — often with hidden seating or a built-in slide — turn a pool into a destination. Each one is sculpted on site and engineered into the structure for durability.
Bubblers, deck jets & laminar jets
Bubblers on a tanning ledge or Baja shelf for kids, arcing deck jets, and crystal-clear laminar jets that glow with LED light after dark. Small touches that make the backyard unforgettable.
Lighting, automation & heating
Color LED pool lighting, smart pool automation, and efficient pool heating tie every feature together — so you can warm the spa, start a waterfall, and set the scene from your phone.
From a single feature to a full showpiece.
Features can be added to a new build or an existing pool, and pricing depends on scope and plumbing. These ranges give you a realistic starting point; every project is quoted line by line. Ask about financing options.
A true custom gunite pool with a clean geometric or freeform shape, PebbleTec finish, and essential equipment — engineered for your lot, not a stock template.
Our most popular range: a larger pool with a raised spa, water features, tanning ledge, LED lighting, and smart automation.
A complete backyard resort — infinity edges, grottos, expansive decking, outdoor kitchens, fire features, and full outdoor-living architecture.
Ranges depend on the feature, materials, and whether it is built into a new pool or added to an existing one. We provide a clear, line-item proposal before any work begins.

Josh and Shan went above and beyond to bring my dream pool to life. This is my third pool, and by far the best experience I've had.
Cannot thank J. Oliver and team for turning our dream into a daily reality and joy we share with family and friends. Two-plus years in and the pool still glistens brightly like the day it was finished.
An easy, hassle-free build from start to finish — very knowledgeable, and they customized the pool just perfectly.
Spas & features, answered.
Can you add a spa or water feature to my existing pool?+
Yes. We add raised spas, spillways, bubblers, and waterfalls to existing pools, integrating the plumbing, equipment, and automation so it looks and runs like it was always there. It is one of the most popular additions during a renovation.
Are spa heating and water features expensive to run?+
We use high-efficiency heaters and variable-speed pumps, and tie everything into smart automation so you only run features when you want them. We size equipment for low operating cost, and a well-designed system costs far less to run than an older single-speed setup.
Can the waterfall or spillway be made quieter or louder?+
Absolutely. The sound of moving water is part of the design — we tune flow rates, drop heights, and weir styles to get exactly the sound you want, from a soft trickle that masks street noise to a full, immersive waterfall.
Can I control the spa and features from my phone?+
Yes. Smart automation from Pentair and Jandy lets you heat the spa, start the waterfall, and set the lighting from your phone before you ever walk outside, then shut it all down with one tap.
How long does it take to heat a custom spa?+
With a properly sized high-efficiency gas heater, most spas reach temperature in 30 to 45 minutes. Because automation lets you start heating remotely, the spa is ready by the time you walk out the door.
What is the difference between a sheer descent and a scupper?+
A sheer descent (or sheet-fall) pours a smooth, wide ribbon of water from a hidden lip, giving a clean, modern look and a soft hush. A scupper is a spout — often from a raised wall or spa — that creates a more defined arc and a louder, more playful sound. We help you choose based on the look and sound you want.
Can you build a grotto with a slide?+
Yes. Natural rock grottos with built-in slides, hidden seating, and waterfalls are a favorite for family backyards. They are hand-built on site and engineered into the pool structure for durability and safety.
Do you offer financing for adding features?+
Yes. Features can be included in financing for a new build or a renovation so you can add the spa or waterfall now and spread the cost over time. Visit our financing page or ask during your consultation.
