What are the pros and cons of a steam shower?

A steam shower gives you a warm, humid, relaxing space inside a bathroom you already have, so a steam session can become part of your daily routine. The trade-offs are cost, a sealed enclosure, a dedicated electrical circuit and some upkeep. Whether it is worth it depends on your bathroom, your budget and how often you would use it.

We sell ThermaSol equipment in our steam shower generators and packages collection, so we have a stake in this question. Everything below comes from our own product pages and installation guides, and we point out the downsides as plainly as the upsides. This is planning information, not wiring or plumbing advice.

What are the pros of a steam shower?

It fits inside a bathroom you already have. A steam shower is a shower stall or enclosure that holds steam, fed by a generator. You do not need a separate room or a backyard slab. The generator does not have to sit inside the shower either: the ThermaSol Pro Series I page states it can be installed up to 50 feet from the shower, so it often lives in a vanity, closet or mechanical space.

It is easy to fold into a routine. People use steam as a calm, warm way to end the day or unwind after a workout. We describe that as comfort and routine, not as a treatment for anything. If you already shower every day, adding steam is a small habit change compared with scheduling a trip to a gym or spa.

Steam arrives quickly. The ThermaSol Pro Series II and III pages list FastStart, which produces steam in seconds, and a design meant to keep the flow consistent without lags or bursts. You are not waiting for a large room to heat up.

The controls can be one touchscreen. Packages such as the ThermaTouch 7-inch round wellness steam package bundle a waterproof 7-inch touchscreen, a round light and sound rainhead and a solid brass steamhead, so one screen adjusts steam, temperature, music and lighting.

Upkeep is built into some generators. The Pro Series II and III list a PowerFlush system that uses pressurized water to clear sediment, and a split tank design that separates heating from the water feed. Neither removes the need for care, but they are aimed at the most common maintenance headache.

It works alongside other recovery habits. Many buyers pair steam with a sauna or a cold plunge. Our guide to sauna vs steam room explains how dry and moist heat differ, so you can decide whether steam is the right first purchase.

What are the cons of a steam shower?

It costs more than a regular shower upgrade. On our shelf, the ThermaSol Pro Series II Advanced starts at $3,799.97 and the Pro Series III Ultimate starts at $4,499.97, before controls, a steamhead, labor and enclosure work. Our breakdown of what it costs to make your shower a steam shower walks through each line item.

The enclosure has to hold steam. Steam is hot, wet air and it finds every gap. Our steam shower installation guide lists a waterproofed, vapor-controlled enclosure with a sealing door as the first decision, and ThermaSol's own manual says the enclosure must be vapor proof. If you are converting an old shower, this can mean opening walls.

The ceiling matters. Steam condenses on cool surfaces, and a flat ceiling can drip on you. The same guide covers sloped or well-sealed ceilings, and it is a decision to make before framing, not after.

It needs its own power. A generator needs a circuit sized to the model, installed by a licensed electrician, plus a water supply, a steam line and a drain path. These are jobs for licensed trades, and local code and the manual have the final say.

Sizing is not optional. Generators are sized by adjusted cubic feet, not floor area. Stone walls, tall ceilings, exterior walls and big glass panels all push the size up. An undersized generator gives you a lukewarm shower, and an oversized one wastes money. Use our steam generator size calculator before you shop.

It adds humidity you must manage. You will want a ventilation fan, and you should plan where moisture goes after a session. Steam is also not for everyone: if you have a health condition, take medication or are pregnant, talk to your doctor before using one.

It stays with the house. A built-in steam shower is a renovation, not a product you can move. If you rent or expect to move soon, a different kind of heat may suit you better.

How do the main options compare on price?

These are the ThermaSol items buyers most often look at first. Prices change, so confirm them on each product page.

A generator and a control package are separate purchases, so a complete setup combines one of each. The ThermaTouch package listing notes it does not include a digital shower valve, so confirm what your plumber needs. Our Pro Series I vs II vs III comparison and our guide to the different types of steam generators help you choose.

Is a steam shower worth it?

It is usually worth it when three things are true. You are already remodeling or building a bathroom, so the enclosure work is part of a job you are doing anyway. You would use steam several times a week, so the cost spreads over many sessions. And you have a licensed electrician and plumber who will size and install the system properly.

It is harder to justify when you would use it a few times a year, when the existing shower cannot be sealed without major work, or when your budget is tight and a simpler way to get warm, humid heat would do. If you are still deciding between types of heat, our guide on how to use a steam room shows what a session looks like, and our steam sauna buying guide covers the self-contained cabin route.

What should you check before you buy?

• Measure the enclosure and calculate adjusted cubic feet, including stone, glass and exterior walls.
• Decide where the generator will live and confirm the steam line distance in the manual.
• Ask a licensed electrician what circuit your chosen kW size needs.
• Plan the ceiling slope, the door seal and a ventilation fan with your builder.
• Choose controls and a steamhead, and confirm whether a digital valve is included.

We have no customer reviews on these ThermaSol products yet, so this guide rests on the manufacturer specs on our product pages and on our own installation guidance. If your numbers sit between two sizes, send us your shower dimensions before you order and we will help you compare.

Frequently asked questions

Is a steam shower worth the money?

It can be if you are already remodeling, would use steam often and have licensed trades to size and install it. It is harder to justify for occasional use, because the generator, controls, enclosure work and labor all add up.

What are the main disadvantages of a steam shower?

Cost, the need for a sealed, vapor-controlled enclosure, a dedicated circuit installed by a licensed electrician, correct generator sizing, ventilation and ongoing upkeep. A built-in unit also stays with the house.

Can I turn my existing shower into a steam shower?

Often yes, but the enclosure has to hold steam, including the ceiling and door. Our installation guide lists the planning steps, and a builder should check your shower before you buy a generator.

How big a steam generator do I need?

It depends on the room volume in adjusted cubic feet, plus stone walls, tall ceilings, exterior walls and glass. The ThermaSol Pro Series I Essential, 11 kW is listed for rooms from 241 to 395 adjusted cubic feet. Use our size calculator to estimate.

Is a steam shower safe for everyone?

Not necessarily. Steam is for relaxation and comfort, and people with health conditions, people who take medication and people who are pregnant should talk to their doctor before using one.
