The bathroom has evolved from a purely functional space into a personal sanctuary for wellness and relaxation. Designers and homeowners alike are embracing elevated features—from hotel-inspired spa wet rooms to digitally connected smart showers. One of the most powerful additions to any bathroom upgrade? A steam shower.
More than just a luxury, steam showers offer physical and mental health benefits—supporting recovery, stress relief, skin health, and sleep. Whether you’re building from scratch or renovating your existing space, here are 10 expert tips to help you design a steam shower that delivers both performance and peace of mind.
1. Determine the Shower Space
Start by identifying your ideal shower location and measuring your space accurately. Consider:
- Square footage
- Ceiling height (for generator sizing)
- Access to plumbing, drainage, and power
- A well-planned footprint sets the foundation for every component of your steam shower.
2. Plan for Proper Ventilation
Ventilation is critical to preventing mold, mildew, and condensation buildup. Install an exhaust fan or a transom window to allow steam to escape post-session. Just be sure any openings can be sealed during use to preserve heat and humidity levels.
3. Slope the Ceiling
Flat ceilings allow condensation to collect and drip, disrupting the spa experience. A slightly sloped ceiling (1–2 inches per foot) helps direct condensation to the wall instead of onto you or the floor.
4. Choose the Right Steam Generator
Size your generator based on your shower’s total cubic feet (Length × Width × Height). Use the Thermasol Steam Generator Calculator to find the perfect fit.
Install your generator in a climate-controlled, dry location—up to 50 feet away from the shower—with 6 inches of clearance for proper ventilation. Make sure it's level and oriented correctly for long-term performance.
5. Position the Steamhead Correctly
- Install your SteamVection™ steamhead:
- At least 24 inches above the shower floor
- With 6 inches of clearance from corners
- Not under benches or seating areas
- For optimal functionality, place the steamhead on a different wall than the control panel.
6. Control Placement Matters
- Your steam control panel should be:
- Installed at 60 inches from the floor
- Positioned near a bench or within arm’s reach
- Located away from direct steam flow for ease of use
- Smart controls like ThermaTouch2 allow for customizable temperature, lighting, and audio from one sleek interface.
7. Use the Right Materials
- Steam showers require non-porous, heat-resistant materials like:
- Porcelain or ceramic tile (easy to clean, durable)
- Natural stone (must be properly sealed)
- Tempered glass
- These materials stand up to humidity while creating a clean, spa-like look.
8. Hire a Licensed Electrician
Steam generators typically require a 208–240V/single-phase power supply and a dedicated circuit breaker. Always work with a licensed electrician to ensure proper wiring, safe placement, and code compliance.
9. Clean & Maintain Your Steam Shower
- Keep your steam shower in top condition with regular cleaning:
- Use gentle, surface-safe cleaners
- Wipe down surfaces after each use
- Schedule periodic maintenance for your generator
Thermasol’s PowerFlush™ system makes it easy to remove calcification and extend the life of your unit.
10. Add Custom Accessories
- Elevate your shower experience with luxury add-ons:
- Chromatherapy lighting
- Bluetooth audio and voice control
- Essential oil infusion with the SteamVection™ aroma reservoir
- HydroVive rainhead with multi-sensory light, sound, and water flow
Your steam shower can be as relaxing or high-tech as you want it to be.
