Indoor Saunas

Bring a Private Wellness Retreat Into Your Baltimore Home

Imagine stepping into soothing heat and complete stillness at the end of a long day—without driving to a spa or wellness club. At Baltimore Custom Saunas, we design and install fully customized indoor saunas that blend seamlessly with your home’s architecture and lifestyle. Whether you live in a historic rowhome in Federal Hill, a condo near the Inner Harbor, or a modern home in Towson or Ellicott City, we transform underused spaces into warm, calming escapes built for daily restoration.

Our indoor saunas are crafted with precision, allowing you to enjoy a personalized retreat year-round. From compact designs that fit comfortably into closets or alcoves to spacious luxury suites connected to bathrooms or fitness areas, we create solutions tailored to how you live, relax, and recharge. Each sauna is engineered for comfort, efficiency, and long-term performance—making it one of the most rewarding improvements you can bring to your home.

What You’ll Get With a Custom Indoor Sauna

Unlike mass-produced or prefabricated kits, every indoor sauna we build is fully tailored to your space, your preferences, and your lifestyle. Our process includes careful space evaluation, architectural planning, and detailed design work to ensure your sauna fits perfectly and performs flawlessly.

If you’re converting a spare room, finishing a basement, or reimagining part of your primary bathroom, our designers will create digital layouts that show exactly how your indoor sauna will look and function before we begin construction. As your local sauna contractor and sauna installer, we handle all technical details, from framing and insulation to heater wiring and safety testing.

Frequently Asked Questions

How long does installation take for an indoor sauna in Baltimore?

Most indoor sauna installations take 3–10 days after materials are delivered.

Our process includes:

A design consultation to plan layout and features

Detailed material selection and scheduling

Coordination with your electrician for power preparation

Complete installation with clean, efficient workmanship

A final walkthrough explaining operation, safety, cleaning, and maintenance

We work with minimal disruption while ensuring your sauna is built to the highest standards.

Can I install a sauna in my basement?

Absolutely. Basements are one of the most popular locations for indoor saunas across Baltimore due to their stable temperature and flexible layouts. Whether you have a finished basement in Rodgers Forge or an underused space in Parkville, we can transform it into a private wellness retreat.

We handle:

Moisture control and insulation

Ventilation planning

Heater or infrared panel placement

Electrical preparation

Basements work well for traditional electric, infrared, or steam saunas, and we tailor the build to suit your available space.

Other popular indoor locations around Baltimore include primary bathrooms in Roland Park, bonus rooms in Columbia, and converted attic spaces in older city homes.

Do indoor saunas need special electrical or ventilation in Baltimore homes?

Yes. Proper electrical and ventilation planning is essential for safety and performance.

Most indoor saunas require:

A dedicated 240V circuit (traditional electric)

GFCI protection for moisture-prone areas

Adequate airflow to manage heat and prevent humidity buildup

We coordinate directly with your licensed Maryland electrician, or connect you with trusted partners if upgrades are necessary. Our designers plan ventilation systems carefully to ensure your sauna operates efficiently without affecting the rest of your home.

What’s the best room in a Baltimore home for an indoor sauna?

Indoor saunas can be added to many areas depending on your home’s layout and lifestyle. Basements are a top choice for Baltimore homeowners because they stay naturally cool and quiet. Primary bathrooms offer a spa-like setup with quick access to showers and tubs.

Other excellent locations include:

Spare bedrooms in neighborhoods like Canton or Hampden

Walk-in closets in Federal Hill rowhomes

Home gyms in Towson, Ellicott City, or Owings Mills

Converted nooks in historic homes throughout Mount Vernon or Fells Point

During your consultation, we review your floor plan, ventilation options, electrical requirements, and wellness goals to recommend the best placement.

What sizes are common for custom indoor saunas?

Saunas can be designed for nearly any interior footprint, but these sizes are often chosen by Baltimore homeowners:

4' x 6' — Ideal for 1–2 people with corner seating

6' x 8' — Great for 3–4 people with multi-level benches

8' x 10' — Perfect for families or integrated wellness rooms

A 7-foot ceiling height is typically optimal for heat distribution, comfort, and efficiency. Ceilings over 8 feet may require additional planning to maintain even temperatures.

We have installed saunas in a variety of unique Baltimore spaces—rowhome alcoves, angled attic rooms, condo closets near the Inner Harbor, and narrow basement corners in Highlandtown. We custom design everything to ensure a proper fit and smooth operation.
