Frequently Asked Questions

Can you install any brand of pre-built sauna?

Yes. Our installers are experienced with a wide range of sauna brands and models, including infrared, electric, wood-fired, and hybrid systems. We regularly install units from manufacturers such as Sunlighten, Almost Heaven, Dundalk LeisureCraft, Harvia, Costco-sourced kits, and others. Regardless of brand, we ensure your sauna is assembled properly and operates safely.

Which pre-built sauna brands are most popular?

Some commonly selected brands include:

* Sunlighten & Sun Home – Known for advanced infrared technology and wellness features

* Almost Heaven Saunas – Popular for barrel-style and compact outdoor units

* Harvia – A respected Finnish manufacturer offering reliable heaters and traditional designs

* Dundalk LeisureCraft – Cedar saunas valued for durability and natural craftsmanship

With so many online options available, we help clients compare features, sizing, and performance before installation.

How does installing a pre-built sauna differ from a custom sauna build?

Pre-built saunas arrive as fully assembled units or modular panels that are put together on site. Unlike custom saunas—where every dimension and finish is designed specifically for your space—pre-built models have fixed layouts and components. Our role is to ensure correct placement, safe electrical connections, proper ventilation, and overall performance. Pre-built saunas offer convenience and speed, while custom builds allow full personalization.

Where can a pre-built sauna be installed in a San Antonio home?

Pre-built saunas are versatile and can be installed in many locations, depending on space and access. Common installation areas include:

* Finished garages or home gyms

* Spare bedrooms or converted storage areas

* Primary bathrooms with adequate space

* Backyard patios, decks, or garden areas

* Covered outdoor spaces designed for privacy

Before installation, we evaluate foundation support, electrical needs, ventilation, and clearances to ensure safe, reliable operation.

Are pre-built saunas more affordable than custom-built saunas?

In many cases, yes. Pre-built sauna units can cost 10–20% less than fully custom projects, depending on size, materials, and features. They’re a great option if you’re working within a defined budget or want a faster installation timeline. Custom saunas, on the other hand, offer complete design flexibility and seamless integration into your home. We help you weigh both options to determine the best long-term value.
