Frequently Asked Questions

How does a steam shower generator work?

The generator heats water in a stainless steel tank outside the shower. Steam travels through a copper or brass line to a steam head inside the sealed shower, and the control on the wall sets the temperature and session time.

What size steam shower does the PROIII-395 cover?

ThermaSol rates the PROIII-395 for up to 395 cubic feet with a ceiling of 8 feet or less. From 141 to 240 cubic feet, the PROIII-240 is the correct size. Above 395 cubic feet, or for each foot of ceiling over 8 feet, move up one size, starting with the PROIII-575.

How do I calculate my room volume?

Multiply length by width by height in feet and round up. ThermaSol sizes by this plain volume, with the ceiling at 8 feet or less. For each foot of ceiling over 8 feet, move up one model size; ThermaSol does not recommend a ceiling over 10 feet. Our size calculator helps you check.

My shower has acrylic walls. Does that change anything?

Acrylic walls must be steam rated by their manufacturer, and ThermaSol recommends only specific generators for acrylic modules. Send us the enclosure make and model, and we confirm the right generator with ThermaSol before quoting.

What do SmartSteam, PowerFlush and FastStart do?

SmartSteam is ThermaSol's patented steam technology, and ThermaSol specifies constant steam at a constant rate, with no steam lag or burst. Auto PowerFlush is a pressurized inner tank cleaning system. FastStart is standard equipment. All three are included on the PROIII-395.

Which control should I choose?

The ThermaTouch2 is a touchscreen in 15, 10 or 7 inch sizes; the 7 inch comes in black trim only. The SignaTouch mounts on the wall or recessed. The MicroTouch comes round for wall mounting or square for recessing. Recessed controls need a rough-in kit, which we add to the quote.

Which steam head should I choose?

The SteamVection head comes in round or square trim in all 15 finishes. The No Touch head comes in polished chrome only; ThermaSol states it is fully compatible with all PRO Series III generators.

Can I add lighting, music or a shower system later?

The PROIII-395 works with ThermaSol Serenity light, sound and rainhead systems, and with ThermaSol's Wellness and Digital Shower packages. In-shower extras are wired behind the tile, so plan them before the walls are closed.

Where can the generator be installed?

In a closet, vanity cabinet, climate-controlled attic or basement, up to 50 feet from the steam shower. The space must be dry, non-combustible and well ventilated, with 6 inches of clearance around the generator and easy access to its front panel. It must stand upright and level with all connections facing up. It cannot go inside the steam room, outdoors, or in an unheated attic where water could freeze.

What electrical service does it need?

A dedicated 208 to 240V single-phase circuit on its own breaker. The PROIII-395 is hardwired, with flexible conduit, and draws up to 55 amps. ThermaSol calls for copper wire rated 90°C, type THHN, and requires a licensed electrician for all electrical work.

What plumbing is required?

A cold water supply with a brass shut-off valve, connected to the supplied 3/8 inch braided hose, using copper or brass fittings only; no galvanized fittings, PEX or PVC. ThermaSol recommends an in-line water filter. The steam line is 1/2 inch brass pipe or copper tubing from the supplied union to the steam head rough-in fitting. The drain pan connects to an approved drain through its 3/4 inch fitting. A licensed plumber completes the work.

How should the steam line run?

The steam line may run up and then down once, or horizontally, but never down and then up, which traps condensate. No valves or traps may be installed in it. Pitch it back toward the generator before any turn up or down and toward the steam room after, and insulate it with steam-rated insulation if the run exceeds 10 feet or passes through a cold area.

Where does the steam head go?

ThermaSol specifies 24 inches above the floor or tub rim and 6 inches from any corner, as far as possible from where bathers sit or stand and from the in-shower control. On a finished wall it needs a 1-1/8 inch hole for the rough-in housing, which is sealed flush to the wall. The head mounts with its aroma well facing up.

Where does the control go?

As far as possible from the steam head and close to where the user sits. The 50 foot CAN-bus cable is included, and ThermaSol recommends running it through electrical conduit, never wrapped around the steam line or routed where the hot steam line could damage it.

What does the steam shower itself need?

Walls, ceiling and floor suitable for steam, a ceiling sloped 1 inch per foot so condensation runs off, and flooring that is safe when wet. ThermaSol notes that an 8-foot ceiling makes a more efficient steam room, and it does not recommend a ceiling over 10 feet.

How is the generator maintained?

Auto PowerFlush cleans the inner tank, and ThermaSol recommends PowerFlush maintenance every 1,000 minutes of use. The generator must stay accessible for servicing, with its access panel unobstructed.

What does the warranty cover?

ThermaSol gives the original purchaser a 2-year In-Home Limited Warranty covering defective parts and labor. After that, the Lifetime Factory Limited Warranty replaces defective parts for the life of the product, with labor at ThermaSol's factory; the owner pays removal, reinstallation and shipping. The warranty covers residential installations only. The full terms are in the manual on the Resources tab.

Is Sauna Republic an authorized ThermaSol dealer?

Yes. Sauna Republic is an authorized ThermaSol dealer. This matters because ThermaSol requires proof of purchase from an authorized reseller to start any warranty claim.

Can I use the PROIII-395 in a commercial steam room?

No. ThermaSol provides no warranty for PRO Series generators installed or used in any non-residential setting, including a hotel. For spas, gyms and hotels, see the ThermaSol PowerPak3 and the ThermaSol Day Spa systems.

How does delivery work?

ThermaSol lists a lead time of up to 1 week. We confirm current availability and the delivery date for your full system when we send your quote.

Can I use HSA or FSA funds?

Steam generators are not HSA or FSA eligible.

Do you offer financing?

Yes. See our financing options.

What is your return policy?

Please review our return policy, or contact us before ordering with any questions.

How do I get pricing?

Build your system in the configurator on this page, or request pricing directly. We reply with a written quote for the generator, control, steam head and any rough-in kit. You can also call (302) 273-0861 or email info@thesaunarepublic.com.

All delivery times are estimates and may extend due to carrier delays or unforeseen circumstances. Backordered items ship when available — we confirm your ETA at time of order. Tracking is emailed as soon as your order ships. Clearlight accessories ordered together with a sauna ship when the sauna ships, by parcel carrier, and may arrive on a different day. Sauna covers are made to order and ship separately, usually after the sauna.

Dundalk saunas are built to order

Changes requested 14 or more days after your order is placed, or within 7 days of the scheduled ship date, carry a $350 fee per change. To delay a scheduled ship date, tell us more than 7 days before it; later requests incur storage charges of $35 per day.

Robes & Textiles

Robes, towels, and bath textiles ship by parcel carrier rather than freight, and follow their own shipping terms.

Free FedEx Ground shipping on textile orders over $100

Orders of $100 or less are charged shipping calculated at checkout. This applies to robes and textiles only — saunas, cold plunges, heaters, and accessories always ship free to the continental United States with no minimum.

Processing & Restrictions

Ground processing — Please allow 3–4 business days for ground orders to be processed before they ship.

Order cut-off — Orders placed after 8:00 AM EST are processed the next business day.

Monogrammed items — Allow an additional 3–5 business days of processing time. This applies to expedited orders as well.

PO Boxes, APO & FPO — Textile orders cannot be shipped to PO Boxes or to APO/FPO military addresses. Please provide a street address at checkout.

Mixed orders — If your order includes a sauna, cold plunge, heater, or accessory, the whole order ships free regardless of the textile subtotal.

Textile orders ship separately from sauna and cold plunge shipments and may arrive on a different date, even when purchased together.

How Freight Delivery Works

Large items (saunas, cold plunges, hot tubs, and most floor-standing heaters and wood-burning stoves) ship via LTL freight. Smaller items (wall-mounted heaters, accessories, wellness devices, Lumaflex, red light towers, robes and textiles) ship via UPS, FedEx, or USPS.

1. We ship your order. Tracking is emailed to you with the estimated delivery timeline.

2. The carrier calls you. The freight company calls to schedule a delivery appointment with you from its available dates and time windows.

3. Curbside delivery. Delivery is to the curb via semi-truck with liftgate (when available). You'll need a plan to move it from the curb to its final location.

4. Sign and inspect. You must be present to sign. Inspect for damage before signing — note any issues on the delivery receipt.

Unloading Your Sauna

Unless inside delivery has been arranged in advance, the driver delivers to the curb only. You are responsible for moving the product to its final location. Have equipment and help arranged before delivery day.

Rent a forklift — Most common choice. Requires forklift extensions. ~$150–300/day.

Hire a tilt tow truck — Flatbed tow with tilt/slide functionality. ~$200–400.

Hire a rigging/moving crew — Professional movers with equipment. Get quotes in advance.

Tilt tow delivery (Dundalk only) — An alternative for sites where a forklift can't be used. Request it when you place your order; contact us for current pricing.

Inside delivery (Clearlight only) — Delivery into your garage, backyard, or a room of your choice, for an additional fee. It must be arranged before the sauna ships, and we'll ask for photos of the delivery path. The boxes are placed, not unpacked or assembled. Requests made after shipment cost more and depend on the carrier.

Clearlight saunas ship in flat panels, not pre-assembled crates. Most can be carried inside by two people without heavy equipment. Dundalk saunas ship in crates longer than 92" weighing 800–1,800 lbs. Liftgate service is not available for these shipments, and most require a forklift with fork extensions to unload.

Damage Claims

If your order arrives damaged, we'll get you a replacement as quickly as possible.

1. Inspect packaging for visible damage before signing.

2. Note damage on the delivery receipt, describing exactly what you see (for example, "crate corner crushed" or "panel scratched"), and have the driver sign. If the packaging is damaged but you can't inspect the contents, write "possible concealed damage" before signing.

3. Do not refuse the delivery unless we ask you to.

4. Take photos of packaging and product damage.

5. Email photos to info@thesaunarepublic.com with your order number within 24 hours.

6. We file the claim and ship your replacement.

Damage must be reported within 24 hours of delivery with photos. Claims filed after 24 hours may not be eligible for a free replacement. Always note visible damage on the delivery receipt — even if it seems minor.

Carriers & Address Info

We reserve the right to select the carrier for all shipments.

Small items (wall-mounted heaters, accessories, wellness devices, red light towers) — UPS or FedEx

Robes & textiles — FedEx Ground. Street addresses only, no PO Boxes or APO/FPO.

Large items (saunas, cold plunges, hot tubs, and most floor-standing heaters and wood-burning stoves) — LTL freight carriers

Lumaflex devices — UPS, FedEx, or USPS

Once large items ship, the delivery address cannot be changed, and the delivery appointment is arranged directly between you and the carrier. If an item is returned due to an incorrect address, you're responsible for shipping costs both ways. If freight delivery fails because the carrier couldn't access your property, it's treated as a return per our return policy.

Remote Areas & Special Locations

Alaska, Hawaii & Puerto Rico — Contact Us Before Purchase

Free shipping does not apply to these locations (except Lumaflex — ships free nationwide). Contact us for a custom shipping quote before ordering. Orders placed without prior approval may be cancelled.

APO/FPO addresses: We ship most items to military addresses, subject to USPS restrictions. Additional fees may apply. Robes and textiles cannot be shipped to APO/FPO or PO Box addresses.

Remote/hard-to-reach areas: Additional fees may apply. We'll contact you before shipping if your location requires special arrangements.

The warranty covers repair or replacement parts, which may be new or refurbished. Labor and contractor fees are not covered.

Claims require photos or video of the issue, a description of the problem, and completion of the manufacturer's troubleshooting steps.

Contact Sauna Republic — we coordinate the claim with Revive Plunge. No restocking fee on warranty claims.

Delivery & Damaged Shipments

Revive products ship by curbside freight. The freight carrier contacts you to schedule delivery, and moving the product from the curb to its final location is the customer's responsibility.

1. Inspect the crate and packaging with the delivery driver present, before signing the bill of lading.

2. Note any visible damage or missing items on the bill of lading. Signing without noting damage confirms the shipment arrived in acceptable condition.

3. Take photos of packaging and product damage.

4. Contact Sauna Republic within 24 hours — email photos to info@thesaunarepublic.com. We report the damage to Revive Plunge and the carrier and coordinate the claim on your behalf.

Concealed damage (not visible until unboxing) must be reported within 24 hours of delivery. Missed delivery appointments may incur redelivery fees. If an undamaged, correct shipment is refused, return freight, redelivery, and storage charges are the customer's responsibility, and the order is treated as a return.

Payment Processing Fees

Applies to all refunds and cancellations initiated by the customer.

Processing Fees Are Not Returned to Us

When you pay by card, our payment processor charges a fee at the time of purchase. Under their terms, that fee is not returned to us when an order is later refunded — the cost stands whether or not the sale completes.

For any return or cancellation initiated by the customer, the processing fee charged on the original transaction is therefore deducted from the refund. This is currently 2.9% of the order total plus $0.30. It is not a fee we retain — it is a cost already paid to the processor.

Where a brand-specific restocking fee also applies, both are deducted.

No Processing Fee Is Deducted When the Fault Is Ours

Products that arrive damaged or defective.

Warranty claims.

Orders we cancel, or errors on our part.

Orders we are unable to fulfil.

Paying by Bank Transfer

Bank transfer and ACH payments carry no processing fee, so nothing is deducted if the order is later refunded. If you would prefer to pay this way, tell us before checkout and we will send a bank transfer invoice instead.

Backorder Cancellation

Orders containing backordered items are subject to a 6% cancellation fee as we are charged by our payment processor when backorders are cancelled. All lead times are estimates and subject to change.

HSA/FSA Purchases

Our standard return policy applies to all HSA/FSA purchases. Products with brand-specific exceptions follow those policies. There is no IRS requirement that HSA/FSA purchases be final sale.

HSA/FSA refunds are processed back to your original HSA/FSA card within 3–10 business days. Truemed cannot redirect refunds to a different payment method.

HSA holders: Notify your custodian to treat the original purchase as a "mistaken distribution" under IRS Notice 2004-50. Returned funds are not subject to income tax or penalties.

FSA holders: The refund goes back to your FSA plan via the original card. If your plan year has ended, the use-it-or-lose-it rule may apply. FSA holders should be especially sure of their purchase before buying.

Processing fees: HSA/FSA payments are processed by card and carry the same non-refundable processing fee described above.

Damage Claims

If your order arrives damaged, we will resolve it as quickly as possible.

1. Inspect packaging for visible damage before signing.

2. Note damage on delivery receipt — write "damaged" and have the driver sign.

3. Take photos of packaging and product damage.

4. Email photos to info@thesaunarepublic.com with your order number within 24 hours.

5. We handle the claim and arrange replacement.

Lumaflex products: Email photos within 24 hours and we arrange a replacement under the manufacturer warranty.

Revive Plunge products: Inspect the shipment and note any damage on the bill of lading before signing. Concealed damage must be reported within 24 hours of delivery. We report the damage to Revive Plunge and the carrier and coordinate the claim. See Revive Plunge policy for full details.

Description

The ThermaSol PRO Series III 395 (model PROIII-395) is an 11 kW steam generator for steam showers of up to 395 cubic feet with a ceiling no higher than 8 feet. It installs out of sight in a nearby closet, vanity cabinet, climate-controlled attic or basement and sends steam through a copper or brass line to the steam head in the shower.

Sized for the Large Walk-In Steam Shower

A shower 7 feet long, 6 feet wide and 8 feet high measures 336 cubic feet, inside this generator's range. ThermaSol sizes by plain volume with a ceiling of 8 feet or less, and calls for the next larger model for each foot of ceiling over 8 feet. The same shower with a 9-foot ceiling therefore needs the PROIII-575. Use the steam generator size calculator to check your room before you request pricing.

SmartSteam, PowerFlush and FastStart

PRO Series III carries ThermaSol's Ultimate designation. Patented SmartSteam is standard, ThermaSol specifies constant steam at a constant rate with no lag or burst, and the Auto PowerFlush system cleans the inner tank under pressure; ThermaSol recommends a PowerFlush every 1,000 minutes of use. FastStart, a split tank design, low-watt-density Incoloy heating elements and stainless steel construction are standard, and two-way digital CAN-bus wiring links the generator to its control.

Choose Your Control and Steam Head

The generator is sold without a control or steam head. The configurator on this page lets you choose the control (ThermaTouch2, SignaTouch or MicroTouch), the steam head (SteamVection round or square, or No Touch) and one of 15 finishes, then add in-shower extras such as a fog-free mirror, Bluetooth speakers or a shower light. Recessed controls need a rough-in kit, which we add to the quote, and the extras are wired behind the tile, so decide on them before the walls are closed.

What Comes in the Box

ThermaSol ships the PROIII-395 with its stainless steel drain pan, a pre-plumbed safety relief valve, a 1/2 inch brass union for the steam line, a 3/8 inch braided stainless steel water connector, a pre-installed in-line water screen, the steam head housing and cable kit, and a 50 foot CAN-bus cable for the control.

Installation Planning

The generator can sit up to 50 feet from the steam shower without moving to a larger kW model. It must stand upright and level with all connections facing up, in a dry, non-combustible, well-ventilated space with 6 inches of clearance around it and an unobstructed access panel. It cannot go inside the steam room, outdoors, or anywhere water could freeze. A licensed electrician hardwires it to a dedicated 208 to 240V single-phase circuit on its own breaker, using flexible conduit; it draws up to 55 amps. A licensed plumber connects the cold water supply, the steam line and the drain pan.

Lifetime Factory Warranty

ThermaSol gives the original purchaser a 2-year In-Home Limited Warranty covering parts with manufacturing defects and the labor to repair them. After that, the Lifetime Factory Limited Warranty replaces defective parts for the life of the generator, with labor at ThermaSol's factory in Round Rock, Texas. The warranty applies to residential installations only. Request pricing or build your system in the configurator above.
