What a Steam Shower Tub Combo Does
A steam shower tub combo is a prefab cabin that fits three things into one footprint: a jetted bathtub, a shower with rainhead and handheld, and a steam session. The enclosure is sealed glass and acrylic with a built-in steam generator behind the back wall. You bathe, drain, stand up, switch the control to steam mode, and the generator fills the cabin with wet heat. Rinse with cold water from the handheld. All in the same 4–5 foot footprint that a standalone tub would take up.
The appeal is simple: in most bathrooms, you pick between a tub and a shower — a combo doesn't force the choice. For a bathroom remodel where you want a soak and a steam session without dedicating two separate plumbing installs and two separate drains, this is the category. For a master bath with existing space for both, two separate units might still make sense — a combo is a space-saver first.
Mesa's Combo Lineup
Every steam shower tub combo we carry is built by Mesa. The combo models split by tub type (whirlpool jets vs air jets), configuration (corner vs rectangular), and handed orientation (left-hand, right-hand, or symmetric).
-
Mesa WS-501 Yukon: Entry combo. Compact corner footprint, integrated jetted tub, 3kW steam generator. Ships in white or gray interior. Good pick for a smaller master bath where a full walk-in combo won't fit.
-
Mesa WS-608A / WS-608P: Rectangular walk-in combo with a jetted tub. 608A ships with clear glass; 608P ships with blue-tinted glass — identical specs otherwise. One of the most popular combos in the line.
-
Mesa WS-609A / WS-609P: Similar walk-in combo format with slightly different interior layout. 609A clear glass; 609P blue glass.
-
Mesa WS-701A: Walk-in combo with a deeper tub and full rainhead. Larger footprint, more interior space.
-
Mesa WS-702A: Walk-in combo positioned between the 608 and 701 in size.
-
Mesa WS-807A: Walk-in combo with extended tub length and integrated jetted bath.
-
Mesa WS-905: Walk-in combo that ships in left-hand or right-hand configuration — the only WS combo with a handed orientation spec. Pick based on which side your plumbing supply and drain sit on.
All seven run the same 3kW steam generator, tempered glass, chrome fixtures, 6 body jets, rainhead, handheld, FM radio with speakers, aromatherapy reservoir, and LED chromotherapy lighting. The tub, layout, and glass tint are what differ.
Whirlpool Jets vs Air Jets
The tub side of a combo uses one of two jet systems — and they feel different:
Whirlpool (water) jets pump the tub water through a pump and back out through wall-mounted nozzles. The flow is focused and massaging, with adjustable pressure. Good for sore muscles, post-workout recovery, and the classic jetted-tub feel. Most Mesa combos ship with whirlpool jets.
Air jets pump pressurized air through pinhole outlets in the tub floor and sides. The result is a finer, bubblier, more diffuse sensation — closer to a champagne soak than a pressure massage. Air jets are easier to maintain (no stagnant water in the pump lines) and quieter.
Confirm which system a specific combo uses on its product page before ordering. If pressure-point massage is the priority, whirlpool. If softer, gentler bubbles and lower maintenance matter more, air.
Configurations: Corner vs Rectangular, Left vs Right
Most Mesa combos are walk-in rectangular — straight back wall, full-height single or bypass glass front, tub across the back of the footprint. The WS-501 Yukon is the exception and fits into a corner.
Handed orientation matters on the WS-905 specifically (and on a few other handed Mesa steam shower models outside the combo category). "Left" or "right" refers to which side the plumbing supplies and drain sit on when you face the unit. Match the orientation to your existing bathroom plumbing before ordering — swapping orientation after the unit arrives isn't practical.
Plumbing Considerations
A combo unit needs more plumbing than a straight steam shower because the tub adds its own supply and drain requirements. Three lines in total:
Tub supply: Dedicated hot and cold supply to the tub faucet, typically 1/2" lines. Pressure 30–70 PSI.
Shower supply: Same 1/2" hot and cold, feeds the rainhead, handheld, and body jets.
Drains: The tub drain and the shower floor drain are separate. Most combos run two 2" drain lines. Some units combine through a single P-trap; confirm on the product page. The tub drain needs to clear the tub's internal height, and the shower drain sits flush with the floor pan.
Electrically, a combo needs the same dedicated 220V/240V circuit with a 20–30A breaker as a standalone steam shower — plus wiring for the tub pump if it's whirlpool (the pump typically runs on a separate GFCI-protected circuit per code). Plan both circuits with a licensed electrician before the unit arrives.
Who a Combo Is For
A combo makes sense if:
- You're remodeling a master bathroom and want both a soak and a steam session without doubling up plumbing rough-ins.
- Space is tight — a 60" combo replaces a separate tub + shower configuration that would otherwise need 90"+ of wall.
- You want the full feature stack (steam, jets, rainhead, chromotherapy, aromatherapy) in a single install.
A combo is probably not the right pick if you have a large bathroom with space for a freestanding tub and a separate walk-in steam shower — two dedicated units give you more flexibility and better individual feature sets. In that case, start with a standalone steam shower and pair it with a separate jetted tub from the whirlpool and freestanding tub lineup.
Installation Complexity
Combo units are more complex to install than straight steam showers because of the additional tub plumbing and the tub pump circuit. Budget accordingly: plumbing rough-in for a combo typically runs 1.5x–2x a straight steam shower install. Electrical is similar if you already need a dedicated 220V line for the steam generator.
Assembly itself is comparable — pre-assembled panels bolt together in 4–6 hours with two people. The tub and cabin base arrive as one piece; walls and glass attach on-site. All hardware ships with the unit.
How to Pick a Mesa Combo
Start with footprint: corner (WS-501) or walk-in rectangular (everything else). Then pick tub type — most Mesa combos use whirlpool jets; confirm on the specific product page. Then handed orientation on the WS-905 specifically. Then glass tint (clear vs blue) on the 608 and 609. Feature stack is standard across the line, so you're not giving up steam performance or chromotherapy whichever combo you pick.
If Mesa's combo lineup doesn't match your space, the broader standalone steam shower lineup includes walk-in and corner units from Mesa and Ariel Platinum, and our full bathroom category pairs tubs, vanities, and fixtures.
