BlueCube Customs

Custom cold plunges,
built for your project.

In-ground, built-in, or made to your dimensions. We work with architects, designers, builders and pool builders, and directly with homeowners. Every one is built by hand in our own shop.

What We Do

Built to your plans.

Most cold plunges are a catalog item you have to design around. A BlueCube custom is built to your site: your dimensions, your materials, and your equipment location. Our welders form each 316 stainless tub by hand, and our woodshop finishes the walnut, mahogany or white maple around it.

We have built customs for private homes, gyms, recovery studios and clubs. Send us your plans, a sketch, or just a description, and we will tell you what is possible.

Who We Work With

One build team for the whole project.

  1. A

    Architects & Designers

    Give us the space and the look. We work from your drawings and send back the dimensions and details you need for your set.

  2. B

    Builders

    We tell you early what the plunge needs for power, drainage and access, so it fits your schedule and your trades.

  3. C

    Pool & Landscape Builders

    Add a cold plunge to a pool or spa project. We build the tub and the equipment, and you set it.

  4. D

    Homeowners

    No designer yet? Tell us where it is going and how you want to use it, and we will take it from there.
