Best Delta Sauna Gear in 2026: 5 Steam Systems Compared
Delta's SimpleSteam line takes a modular approach to home steam bathing: pick a generator sized to your shower, add a control and steam head, and you have a steam bath without a full sauna build. The SimpleSteam 7.5kW kit is our top pick for most homes: its output sits in the middle of this list, it ships with the square digital control, and it matches the scale of a typical walk-in shower. The picks below come from the five Delta listings in our catalog and are judged on stated specifications, with live prices printed on the page.

Which pick fits you?
- For a large tiled steam shower: If your enclosure is big and you want the most headroom, the 15kW kit is the highest-output generator in this list. See pick 2
- For a standard bathroom remodel: The 7.5kW kit pairs mid-size output with a square digital control, a strong match for a typical walk-in shower. See pick 1
- For a compact shower stall: The 6kW kit's lower output suits a small enclosed shower where a larger unit would be wasted. See pick 3
- For easy generator upkeep: The auto drain and pan kit automates flushing so scale does not build up in a 240V Delta generator. See pick 4

1 Best overall
Delta Faucet SimpleSteam 7.5kW Steam System Kit Matte Black
- Product type
- Steam generator
- Power
- Over 6 to 8.5 kW
$1,738.52 (as of 11/01/2026 09:39 PST - Details)
The 7.5kW kit is the middle of the Delta range here, specified for over 6 to 8.5 kW, which fits most home steam showers. It includes the square digital control in matte black, so generator and control arrive as one kit. Compared with the 15kW model, it asks less of your electrical service; compared with the 6kW, it has more headroom for a larger enclosure.
Pros
- Power output of over 6 to 8.5 kW, the middle of this list's range
- Includes the square digital steam control in the kit
- Matte black finish that suits modern baths
Cons
- Output below the 15kW kit for large steam showers
- Matte black is the only finish shown in this listing
- Needs a dedicated 240V circuit and a drain line
Good fit if
- Homeowners remodeling a standard walk-in shower
- Buyers who want one kit with generator and control
Skip if
- You have a very large or multi-head steam shower
- You want the top power in this list
Verdict: The best-balanced Delta steam kit for a typical home shower.
2 Most powerful
Delta Faucet SimpleSteam 15kW Steam System Kit Matte Black
- Product type
- Steam generator
- Power
- 9 kW and up
$2,399.00 (as of 11/01/2026 09:39 PST - Details)
This kit's power output is 9 kW and up, the strongest in the Delta group, and it includes the square digital control with a matte black finish. It is the pick for a large tile-and-glass steam shower where a mid-size generator would struggle to hold temperature. The trade-off is a heavier electrical load and more service capacity than the 7.5kW kit.
Pros
- Power output of 9 kW and up, the highest in this list
- Includes the square digital control in the kit
- Matte black finish
Cons
- Heaviest electrical demand of the three generator kits
- Overkill for a compact shower stall
- Matte black is the only finish shown in this listing
Good fit if
- Large walk-in showers that a 7.5kW unit cannot hold
- Enclosures with a dedicated 240V circuit already planned
Skip if
- A small enclosure that a 6kW unit could handle
- A service panel that cannot spare a large 240V circuit
Verdict: The Delta generator for big steam showers that need maximum output.
3 Best for small steam showers
Delta Faucet SimpleSteam 6kW Steam System Kit Brushed Nickel
- Product type
- Steam generator
- Power
- 4.5 to 6 kW
$1,475.00 (as of 11/01/2026 09:39 PST - Details)
Power output of 4.5 to 6 kW, this kit is the smallest generator in the Delta list and suits a compact enclosure of about 3 by 3 feet. It still includes the square digital control, and the brushed nickel finish is the only bright option among the three generator kits here. It is the sensible pick when a 7.5kW unit would simply cycle off.
Pros
- Power output of 4.5 to 6 kW, the smallest in this list
- Brushed nickel finish, the only bright option in this list
- Includes the square digital control
Cons
- Not enough output for larger steam showers
- Brushed nickel may clash with matte black fixtures
Good fit if
- Small shower stalls and half baths with steam
- Buyers who want the gentlest electrical load of the three
Skip if
- A large enclosure that needs the 15kW unit
- A fixture scheme built around matte black
Verdict: A compact Delta kit sized right for a small steam shower.
4 Best maintenance add-on
Delta Faucet Steam System Steam Generator Auto Drain and Generator Pan
- Product type
- Steam generator
$499.00 (as of 11/01/2026 09:39 PST - Details)
This listing pairs an auto drain with a generator pan for 240V Delta units. An auto drain flushes the generator after each steam bath, which steam makers recommend to slow scale buildup and keep steam clean. It is an add-on, not a standalone system: it needs a Delta generator, and its own power output is not stated by the seller.
Pros
- Auto drain flushes the generator to reduce scale buildup
- Generator pan catches drips and protects the floor
- Pairs with any 240V Delta generator
Cons
- Not a complete steam system; needs a Delta generator
- Power output not stated by the seller
- Adds plumbing work at the generator location
Good fit if
- Owners on hard water who want automated flushing
- A Delta generator install where a drip pan is required
Skip if
- You plan to flush the tank manually each month
- You are buying your first system and still need a generator
Verdict: A useful add-on for keeping a Delta 240V generator clean and contained.

Why these made the list
The pool for this guide holds five Delta steam and sauna listings from the catalog. We kept all five because each fills a distinct role: the 15kW and 7.5kW generator kits, the 6kW entry-level kit, an auto-drain and pan add-on, and a control unit with steam head. Shortlisting used only the specifications listed by the seller, including power output in kilowatts and what the kit includes. Where a specification is missing in a listing, we mark it as not stated by the seller. Prices on this page are live and are read from the store listing at the time of writing, so they update on each visit. Nobody on this site has used or installed these units, and we did not use customer feedback in our selections. Sizing and installation guidance comes from manufacturers' published FAQ pages, cited in the sources.
Things to weigh before buying
Match the generator size to your shower
Steam generators are sized by the volume of the enclosure they have to fill. Amerec and MrSteam both offer sizing calculators that start with the shower's length, width, and ceiling height; taller or poorly insulated rooms push you up a size. A small opening of about 3 by 3 feet is enough for a steam shower, but the generator output has to be matched to the cubic footage. The three Delta generator kits here cover 4.5 kW up to 15 kW, so measure your space and use the manufacturer's guidance to pick the right one.
Plan the electrical and plumbing requirements
A residential steam generator runs on a dedicated 240V circuit, similar to an electric water heater, and needs a cold water supply plus a drain line. The auto-drain kit in this list automates flushing the tank, which steam makers recommend to reduce scale buildup, especially with hard water. If you are adding steam to an existing shower, factor in the cost of running a new circuit and the space for the generator, which can be mounted under a bench, in a closet, or in an attic as long as it is dry and ventilated.
Decide between a full kit and separate parts
The 6kW, 7.5kW, and 15kW Delta kits each include a generator and a square digital control, so they work right out of the box for a new steam shower. The auto drain and pan listing is a maintenance add-on for an existing generator, and the SteamScape control and head is a finishing upgrade. If you are starting from scratch, buy a kit; if you already have a Delta generator, the add-on and control let you extend it without replacing the core.
Check the finish and control style
Delta offers the generator kits in matte black (6kW and 7.5kW kits) or brushed nickel (6kW kit), and the SteamScape package in Lumicoat Champagne Bronze. The square digital control is the standard across the kits, while the SteamScape uses a transitional square design. Choose a finish that matches your bathroom fixtures; if you are mixing metals, keep the control and steam head on the same tone for a cohesive look.
Understand what the seller does not state
The listings for the auto drain and the control unit do not state a power output, because they are not heating elements. For the generators, the output ranges are given in the specifications, but exact dimensions and installation details may not be fully listed. When a spec is missing, we say not stated by the seller rather than guess. Use the manufacturer's sizing tools and ask a licensed electrician or plumber for help with the hookup.
Questions
What size Delta steam generator do I need for my shower?
Measure the length, width, and ceiling height of your shower to get the cubic footage, then match that to the generator's power output. The Delta kits here span 4.5 kW to 15 kW: a compact stall of around 3 by 3 feet typically works with the 6kW unit, while a large walk-in may need the 15kW. Maker sizing calculators, like MrSteam's VirtualSpa, provide a more precise recommendation.
Can I install a Delta steam generator myself?
Installation needs a dedicated 240V electrical circuit and a cold water supply, similar to a water heater, plus a drain line. It is best handled by licensed electricians and plumbers, especially in a remodel. The generator itself can sit under a bench, in a closet, or in a dry, ventilated attic, but it must be near the shower to keep the steam line short.
How long does it take for a steam shower to heat up?
Steam typically begins to flow within 3 to 5 minutes after the system is turned on, and the room reaches its target temperature in another 10 to 15 minutes, depending on the wall material and insulation. Manufacturers suggest waiting until the room is fully warm before you enter to get the full benefit of the steam bath.
Do I need a special drain for a steam generator?
You need a way to drain and flush the generator. The auto drain kit in this list automates that process by flushing after each steam bath, which is especially useful in hard water areas. Without it, you should flush the tank manually on a regular schedule. A standard floor drain is not required, but a generator pan is recommended to catch any drips.
Can I add a Delta steam control to an existing shower?
Yes. The SteamScape control and steam head package is designed as an upgrade for an existing Delta steam system. It provides a dedicated wall control and a matching steam head in Champagne Bronze. If you already have a Delta generator, you can retrofit this control without replacing the generator, as long as the wiring and control connection are compatible.
