Indoor Saunas

Yes—basements are among the most requested locations in Irvine homes. Their cooler temperature and privacy make them ideal for wellness spaces. We’ve built custom basement saunas in neighborhoods throughout Irvine, Lake Forest, and Tustin—ranging from compact infrared units to full-scale steam saunas.

Basement builds can be standalone wellness retreats or connected to existing gyms, bathrooms, or entertainment spaces. We ensure proper ventilation, insulation, and heating for safe, efficient operation. Whether you want a cozy one-person setup or a multi-bench family retreat, our team adapts the design to fit.

Other popular spots include master bath suites in Newport Coast, converted closets in Laguna Hills, and garage studios in Costa Mesa. We’ll help you explore every option to find the perfect fit.

The average timeline is 3–10 days once materials arrive. We start with a consultation, create a detailed design plan, and coordinate all necessary prep. Our installers work efficiently and respectfully in your home, and once complete, we provide a full walkthrough so you know exactly how to use, maintain, and enjoy your new sauna.

Indoor saunas can be installed in many areas, depending on your goals. Basements work well for larger builds and maintain stable temperatures. Master bathrooms offer spa-like convenience, while spare bedrooms, converted closets, and home gyms provide flexibility. During your consultation, our team will assess ventilation, available space, and layout to recommend the best placement for performance and comfort.

Yes—safe operation requires proper planning. Most indoor saunas need a dedicated electrical circuit and GFCI outlets. We’ll coordinate with your electrician or recommend a trusted local pro to ensure everything meets code. Ventilation is just as important—our designs allow for airflow and quick drying between uses, protecting your walls and extending the life of your sauna.

Indoor saunas can be built in almost any shape or size. At The Custom Saunas Pros Of Irvine, we’ve created compact one-person saunas as small as 4’ x 4’ and family-size builds up to 8’ x 10’.

Ceiling height is also important—most units are around 7 feet tall to contain heat efficiently while still offering comfort. Taller ceilings (above 8 feet) are not recommended with traditional heaters since they make even heating more difficult.

Here are some popular layouts:

* 4’ x 6’ → 1–2 people with a corner bench

* 6’ x 8’ → 3–4 people with tiered seating

* 5’ x 7’ → small families or dual-purpose gym spaces

For unique spaces—like angled ceilings, alcoves, or walk-in closets—we design fully custom layouts that maximize every inch without compromising safety. We’ve completed installations across Irvine, Huntington Beach, and Fountain Valley in everything from narrow nooks to large remodel projects.

If you’re unsure about sizing, don’t worry—our team will measure your space and suggest the best configuration to suit your daily habits and long-term goals.
