Custom Hot Tub Design

Our custom design options allow you to have a spa or hot tub that blends seamlessly with your backyard’s landscape design and is even illuminated by strategic landscape lighting for an after-dark oasis.

Hot tubs can be placed or configured in several ways to best suit your backyard space. No matter which configuration you choose, our team makes your outdoor spa more beautiful with customized landscaping or rock features.

Pool with built-in hot tub

Building a custom pool and hot tub at the same time can be a great way to transform your backyard pool into a true resort-style retreat. With this setup, it’s easy to take a dip in the pool before settling in the hot tub to unwind. For backyard pool and hot tub ideas, you can browse our portfolio of work below from Utah homeowners like you.

Custom in-ground hot tub

Hot tubs built into the ground can keep a smaller yard from looking overcrowded and are a unique upgrade that gives your hot tub a bespoke, high-end look. In-ground hot tubs are often placed in an outdoor, custom patio for easy access.

In-ground hot tub with waterfall

A moving water feature like a custom waterfall is a great way to elevate custom in-ground hot tub designs. With a waterfall’s calming sound and visual interest, your escape will feel that much more special.

Above-ground hot tub

An above-ground spa or hot tub is familiar to most and is the easiest to install and start enjoying sooner. Our team can introduce custom rock features and other unique landscaping ideas to help your hot tub blend in with your backyard’s surroundings.

Concrete hot tub designs:

Concrete is an excellent material for your design, as it can be molded, shaped, and finished in nearly endless styles and designs. Our team often uses concrete to achieve a natural rock-like appearance that fits your hot tub shape and size perfectly.

Brick hot tub designs:

Brick is another favorite material that stands up to wear and tear as well as water. Brick can be used as an accent material to elevate the look of your built-in spa; it can also be effective for matching the look and feel of your home or patio.

Custom stone hot tub designs:

Natural stone is beautiful and highly durable. Local Utah sandstone is a top choice for decorative stone to achieve a unique hot tub look.

Tiled hot tub designs:

Tile is a popular choice for hot tubs and pools. Its smooth, even surface and endless colors and shapes make it a fun and creative material.

Hot Tub Components

As part of your custom outdoor spa design, Stevenson Brothers installs the necessary components to operate your new outdoor escape. This includes the shell, pumps, jets, filters, blowers, and more. Custom hot tubs do require plumbing hook-up and will need to pull power from an electrical source. Luckily, close proximity to your home means these utilities often don’t pose many difficulties. Our team will take care of everything — from electrical and plumbing design to installation — so when we’re done, you’ll be able to flip a switch and enjoy.

Hot Tub Sizes

When going with a custom approach to your built-in spa, you can choose how large or small you’d like it to be. Think about how you plan to enjoy your custom spa: will you entertain groups of family or friends? Or do you want it to be a retreat for you and your partner? From large to cozy hot tubs, we provide professional suggestions for the length, width, and overall size that will meet your vision.

Custom Hot Tub Covers

The final piece of every hot tub design is the cover. This feature will protect your hot tub from the elements and keep its water safely out of reach of pets and children. Custom designs usually require a custom cover. We create ours using ultra-durable polyester, canvas, or vinyl that is both heat and water-resistant, so it will last for years. We also offer the option of electrically powered retractable covers for customers looking to add a little extra convenience to their backyard.
