Best Steam Shower Conversion Kits and Tub Shower Upgrades
If you want a true steam shower, choose a steam generator kit such as the Delta SimpleSteam, VEVOR 12 kW, or Hapyvergo 6 kW. These generate steam but are different from standard tub-to-shower conversion kits, which add a shower to a bathtub without producing steam. The right option depends on whether you want a steam system or a conventional shower upgrade.
| Product | Best For | Type |
|---|---|---|
| Delta SimpleSteam 10 kW | A coordinated steam system kit | Steam generator |
| VEVOR 12 kW | Feature-rich steam control | Steam generator |
| Hapyvergo 6 kW | A smaller stated steam-room capacity | Steam generator |
| GBBNE 70-Inch Riser | A standard tub-to-shower upgrade | Shower conversion |
| DANCO Add-A-Shower | Clawfoot tubs | Shower conversion |
Delta SimpleSteam 10 kW System
Best for: Buyers seeking a named, coordinated steam kit with the generator, controls, and steam head included. The listed package contains a 10 kW generator, square digital control, and square steam head.
The generator is part of a range listed in 4, 6, 7.5, 10, 12, and 15 kW sizes. Its compact design permits installation in a vanity, closet, insulated attic, or basement, according to the product details. This is a steam system rather than a tub-shower riser kit, so it suits a project intended to add steam functionality.
Limitation: The supplied details do not state a room-volume capacity or installation requirements. Confirm sizing and the full installation plan before choosing a generator.
VEVOR 12 kW Steam Generator
Best for: Buyers who prioritize adjustable controls and automatic drainage. The listed features include temperature adjustment from 77°F to 131°F, a customizable 24-hour timer, touch controls, and automatic drainage.
The product information also lists protection against overheating, water shortage, and overpressure. It has a stainless-steel tank with a magnesium rod and segmented heating. The manufacturer describes steam generation within five minutes; treat that as a product claim rather than a guaranteed result for every installation.
Limitation: A 12 kW rating alone does not establish suitability for every steam-room size. Check the required capacity for the planned enclosure and confirm installation details.
Hapyvergo 6 kW Steam Kit
Best for: Buyers comparing a lower-output generator with a stated capacity of 212 cubic feet or 6 cubic meters. The kit lists an aromatherapy steam head, LED controller, and self-draining system.
The manufacturer describes an all-stainless-steel body and a tank with a magnesium rod. The automatic drain is intended to empty water after use. The instructions recommend installing the controller outside the shower because moisture may cause false-touch problems.
Limitation: The stated room capacity should be checked against the actual enclosure and installation conditions. Aromatherapy is an included feature, but it does not replace confirming the generator’s suitability.
GBBNE 70-Inch Tub Shower Kit
Best for: A bathtub without a built-in shower, when the goal is a conventional shower rather than steam. The wall-mounted kit includes a 70-inch riser, a 360-degree swivel shower head, and a pull-up diverter for switching between tub and shower flow.
The listed construction combines a SUS304 stainless-steel riser with ABS components. Its stated flow rate is 1.8 gallons per minute. The polished chrome finish is one of three listed finish options in this group, alongside brushed nickel and matte black.
Limitation: This product does not generate steam. Check the tub and wall setup against the product’s installation requirements before purchase.
DANCO Clawfoot Tub Add-A-Shower
Best for: Owners converting a clawfoot tub into a bathtub-shower combination. The kit includes a diverter faucet, shower head, pipe coupling, support hardware, and a 24-by-24-inch shower curtain ring. Listed faucet centers are 3-3/8 inches.
The shower head has a listed outer diameter of 1-7/8 inches, and the maximum stated flow rate is 2.0 GPM. The supplied hardware supports a clawfoot-tub-style installation, making this a more specific choice than a general wall-mounted riser.
Limitation: The listed package does not include the ceiling supports, curtain ring, faucet, or showerhead, despite listing the curtain ring and showerhead dimensions. Verify the exact package contents and required parts before ordering.
Buying Guide: How To Choose A Steam Shower Kit
Do you want steam or just a shower?
A steam generator heats water to produce steam for an enclosed shower space. A tub-to-shower conversion kit adds a shower head and related plumbing to a tub. The GBBNE and DANCO products are conventional shower conversions, not steam systems. Choose by function first to avoid buying a product that does not meet the main goal.
How should you compare generator capacity?
Compare the generator’s kilowatt rating with the room capacity specified by its manufacturer. The supplied details give Hapyvergo a stated 212-cubic-foot or 6-cubic-meter capacity, while Delta’s listed range describes available generator sizes. The VEVOR listing gives 12 kW but no room capacity in the supplied features. Do not select by wattage alone.
Which controls and maintenance features matter?
Consider whether the kit includes a controller and steam head, and whether it provides automatic drainage or operating safeguards. VEVOR lists temperature control, a timer, and several protections. Hapyvergo lists an LED controller and automatic draining. Delta lists a digital control and steam head. Confirm what is included and what installation components must be sourced separately.
What should you check for a tub conversion?
Confirm that the conversion style suits the bathtub. The DANCO kit is specifically described for clawfoot tubs, while GBBNE is a wall-mounted riser kit for tubs without a built-in shower. Check dimensions, mounting points, faucet arrangement, and package contents before purchase.
