One heck of a steam machine!
This is an amazing steam generator! It wasn't exactly easy to install, so it's definitely not a DIY kind of project, but it sure makes a great addition to the house!

Easy to install
The Detal SimpleSteam Kit is sleek in design and easily fits under a sink or in a cabinet. Having the steam kit installed required basic plumbing skills.

Amazing but a little work to install
Luckily we are in the process of remodeling our bathroom, otherwise it would have been a lot more work to install. He have an older house, so this was a great way to upgrade our bathroom and make it feel like a spa. I love the essential oil reserve, after a stressful day it is an amazing way to unwind. We have hard water, so I am curious to see how it holds up over time.

Q&A
Need a coupler for the control wire for a 5p e5t07 pr
The coupler is supplied with the system. If you need to order a replacement part, use part# EP103494

Does the distance placement of the Steam generator unit effect how long it takes to deliver the steam? For example how long for steam delivery with 4 feet verses 20 feet distance?
Hello,
Yes, if you have a larger plumbing run it will affect the time it takes to produce steam. There will be additional plumbing that will need to be heated up before steam will enter the steam room.
Date published: 2024-07-09
How does this system do with well water?
It depends on how often the product is used, if there is an autodrain option installed and on the quality of incoming water from the well.
Date published: 2025-02-11
Can the generator be housed outside if protected by enclosure? If outside, is a drain pan still a better option? Is an auto drain a good option outside in the enclosure
No, the steam generator MUST be installed indoors, under the same conditioned air quality as other indoor products.
Date published: 2025-02-11
Can i use a condensate pump for the drain water? Since its not boiling hot anymore i would think it would be fine.
It depends on the temperature rating of the pump you are using and if an optional AutoDrain is installed. If there is an optional AutoDrain installed, then the water temp when draining will be under 130ºF.

Hello, I recently purchased and installed Simple steam 6kw system to replace a similar steamier unit. It gets the shower hot but there really is not much actual steam. The steam outlet drips water where my last unit did not. How can I get more steam?
Same issue here. How long should I expect the break in period to take?
Date published: 2025-05-19
What is the operating pressure of the steam outlet?
It is zero pressure. At boiling point steam is made and travels through an open steam pipe into the steam room.
Date published: 2025-12-16
Will the SimpleSteam system ever get the polished nickel finish?
Not at this time, however we have other Steam product lines which do offer a Polished Nickel trim, such as the Delta SteamScape system.

So the unit we got did not have fuses installed in unit. What type of fuses go inside? I thought inside it says .25amp but in manual it says 0.5 What amp and type is it please? Thank you
Inside the steam generator, on the circuit board, there are two fuses. They are 0.25amp, 250Volts, Normal Blow or Slow Blow are proper, just do not use fast-acting fuses.

What has replaced the SM- 11? Who is the local dealer and installation company in my area.
If you have a 60amp breaker, then this is the proper replacement system: 5P-EST12.
If the breaker is only a 50amp, then this is the replacement system: 5P-EST10.
We would need your location to see if there is a recommended installer in your area, vs using your local Plumber.

Does it have a self-cleaning feature? How do I keep the generator from getting clogged up with water deposits?
We offer an optional AutoDrain, which may be purchased separately. Product# 5GA-ADD-240

Can the Delta unit be used as a direct replacement for 1 year old Elite Steam unit? (Will controls and connections be the same?)
Hi JBurns719,
Yes, the Delta Simple Steam will be a direct replacement for the Elite Steam Product.

Electric specs says something line: Volts/Phase/ Max. Amps = 240/1/42 Question: can it be installed with two phases each around 110/120? (220v, what we usually have in Mexico)
This product will work on 220Volts in Mexico, however the output will be reduced from 10kw down. Delta offers 220Volt specific products for Mexico, please take a look at the Delta SteamScape product line, models: 5GE-SMP10-220-1 (steam generator) and 5CH-250T-PR (user control with steam head).

Do you sell extensions to the control wire ? i need it to run about 40’
Yes. The product is supplied with a 35' cable. We offer 10' (part# 5GA-401) and 35' (part# 5GA-403) extensions, also a single 50' cable (part# 5GA-405).

What is the operating pressure of the steam outlet?
It is zero pressure. At boiling point steam is made and travels through an open steam pipe into the steam room.
Date published: 2025-12-16
Are the steam heads and generator self cleaning?
The product is maintenance free, however an optional AutoDrain is available for area with hard water.
Date published: 2024-07-09
Does the auto drain mix with cold water prior to activation? Does it cool the water to an acceptable temperature for discharge into PVC drain/waste plumbing?
Once one is done with a steam cycle, there is a 6-8 hour delay, before the optional autodrain opens, at which point the draining water temperature will be below 130ºF.
Date published: 2025-02-10
What size water supply this model should have
It has a 3/8" compression fitting on the water inlet.
Date published: 2026-01-19
Hello, is this the same model as the Steamist SMP-12 ?
Hi Siska,
The Delta Simple Steam is equivalent to the Elite Steam 12kw. The Steamist SMP-12 is equivalent to the Delta Steam Scape 5GE-SMP12-24-1

Hello - What is the rated energy efficiency of you 10kW electric steam generation unit?
In general, electric heat is nearly 100% efficient.
Date published: 2025-02-11
The autodrain comes with bare wires (no connector). The instructions show a terminal for connecting to the control board on the steam unit, but no connector on the autodrain wires. Also, the picture does not match the board. How to I make the connection?
The AutoDrain wires are connected inside the valve, the other end of the wires connect to a terminal marked "Drain", which is a green block with two screws in the lower right corner of the circuit board inside the steam generator.

Where can I purchase the controller ONLY?
The control ONLY, is a Delta Faucet part# EP103305BL. You may purchase it from any Delta Faucet dealer. Location of the dealers may be found on our Web site:

The controller overestimates the temperature inside the shower and turns off. The controller was installed away from the heating unit. Also getting both an E1 error code and E3 error code. Does this mean I need to replace the controller?
This has to be troubleshot further, please contact the tech support team at steam-product@deltafaucet.com or 800-394-6478. Questions will be, did this issue occur when it was first installed? Where is the control mounted in correlation to the steam outlet?
Date published: 2025-02-25
how difficult would it be to replace an old Steamist SM-5TC generator and controller with this unit?
The Old SM-5-TC has a larger KW Rating than the 5P-EST04. With the correctly sized unit, the unit swap out is straight toward. The control uses a different cable for connection. So a new cable must be run from the steam unit to the steam room.

I see mention of an aroma well on the steamhead but there's no instructions on how that should be used - how much to put in? what to put in it? how often?
You may add a few drops of Aroma Oil into the well and as it heats up, the oil will evaporate into the steam room.
Date published: 2025-02-11
Where is a good place to vent the relief valve line?
We recommend to route it to indirect waste. Some people run it to a slop/washer sink, others outdoors. Some run it on a separate pipe into the steam room and locate the outlet in a corner of the room, away from user space.

How do I descale unit
This product is maintenance free for residential applications. Descaling is not required. We do offer an optional AutoDrain Valve for it, in the event draining is needed.

Thinking about purchasing the Delta 5P-EST10-BL steam generator package. Wanted to know 1) how long does it take for the steam to fill up in the shower 2) how quiet is the generator 3) is the "auto drain" option the same as "auto flush" that I'm seeing
Hi Lisa,
The unit will take about 5 minutes before you start to get steam into the steam room. We state that you should raise the room temp by 25 degrees within the first 15 minutes.
We do not have a decible noise level.
THe auto drain and auto flush are the same feature.

Our unit will be installed in an unfinished basement close to a floor drain, does it need a drain pan? Also can it be mounted on a shelf and strapped to keep it from moving or a potential fall?
We do not require a Pan. Yes, it may be mounted on a shelf, back of the cabinet has punchouts to allow one to secure it to the wall.

Hi saddle,
