A combo tower is sold as one cabinet, but ordering one sets off a chain of changes on the other side of the kitchen. Put the wall oven and the microwave into a single tall unit and the range becomes a cooktop, the microwave above it disappears, the space over the burners is free for a real hood, and the cabinet under the cooktop becomes a drawer base. A Fabuwood Galaxy Horizon combo oven cabinet is 33″ wide in four heights, GH OC3384C to GH OC3396C, at $1,677.00 to $1,836.25. This page follows the chain link by link and prices each link in this finish.
The cooking wall before and after
Most kitchens that consider a combo tower start from the same arrangement: a freestanding or slide-in range with an over-the-range microwave above it, sometimes with a countertop microwave as well. The combo tower takes the oven and the microwave out of that wall. Here is what replaces them.
| Position | Before | After | Priced in this finish |
|---|---|---|---|
| Oven | Inside the range, near the floor | In the tower, below the microwave | GH OC3384C–OC3396C, $1,677.00–$1,836.25 |
| Microwave | Over the range, or on the counter | In the top opening of the tower | Housed in the tower’s upper opening; the microwave wall cabinet drops off the order |
| Burners | The top of the range | A cooktop set into the counter | The counter and cooktop are bought separately |
| Under the burners | The range oven | A drawer base for pots and pans | GH DB30-2 at $835.25; GH DB36-2 at $1,017.25 |
| Above the burners | The microwave, doubling as a weak vent | A wood hood with its own blower | Shells from $2,418.00 for the 36″ GHZ RHA363021, plus a blower from $419.25 |
Link one: the tower itself
The combo tower holds a wall oven with a microwave or speed oven above it. Both appliances are chosen before the cabinet, and both installation guides are sent to us, because two appliances have to fit one cabinet. We confirm the fit from the model numbers and never quote cutouts ourselves. The four heights match the pantries and the other oven towers, so choose the one that lines up with the rest of the tall wall.
- GH OC3384C, 84″ tall: $1,677.00
- GH OC3390C, 90″ tall: $1,755.00
- GH OC3393C, 93″ tall: $1,758.25
- GH OC3396C, 96″ tall: $1,836.25
The tower also needs its own landing spot. Hot dishes come out of the oven and bowls out of the microwave, so keep a stretch of counter within a step of it. Our tall cabinet guide covers where towers sit in a layout.
Link two: the range becomes a cooktop over drawers
With the oven gone from the cooking wall, the burners become a cooktop set into the counter, and the space below it becomes storage. The best use of that space is usually wide drawers for pots and pans, which then sit directly under the burners they are used on. In this finish, the two-drawer bases are GH DB30-2 at $835.25 and GH DB36-2 at $1,017.25 on the base cabinets page, sized to the usual 30″ and 36″ cooktops.
One check before ordering: a cooktop drops some distance below the counter, and gas cooktops need room for their burner assembly and gas connection, electric and induction ones for their electronics. That depth can limit the top drawer. The cooktop’s installation guide says how much space it needs underneath; send it with the order and we will tell you whether a drawer base works or whether a door base is the safer choice.
Link three: a real hood where the microwave was

This is the link most people underestimate. An over-the-range microwave vents weakly, and removing it frees the space above the cooktop for a proper range hood. This finish offers wood hood shells stained to match the cabinets, from $2,418.00 for the 36″ GHZ RHA363021 up to the designer and curved-glass styles, on the hoods page. A stained wood hood becomes the focal point of the wall, and on this grey-taupe the grain carries up the chimney in a way paint cannot.
A vented hood is two purchases, the shell and the blower insert that goes inside it. Blowers in this line are the 250 CFM at $419.25, the 400 CFM at $903.50 and the 600 CFM at $1,787.50, on the internal blower page. Every insert fits every shell except one: the 250 is not offered for the 48″ RHA483021. Where the hood cannot be ducted outdoors, GHZ RHBB DCT at $263.25 is a recirculating kit rather than trim; it converts an insert to recirculating use with a charcoal filter, and GHZ RHBB FLTR at $71.50 is that charcoal filter’s refill. Our guide to range hood CFM explains how to size the blower and the duct.
Fabuwood’s wood hoods ship with a full stainless steel interior liner, which protects the wood above the cooktop. The cabinet you no longer need is the one that used to hold the microwave: the 30″ microwave wall cabinets on the microwave wall page (GH MW3018 at $360.75, for example) drop off the order.
Link three and a half: setting the hood and the cabinets beside it
Once the hood is in, the wall cabinets either side of it need to agree with it. The hood’s height is set by the ventilation, not by the cabinets. The insert guide that matches Fabuwood’s 400 and 600 CFM blowers puts the bottom of the hood no less than 24″ and no more than about 30″ above the cooktop, and many gas cooktop manuals ask for at least 30″ to combustible material; whichever figure is higher wins. The flanking wall cabinets then line up with the hood, usually at the same top line under one crown, with the shell sitting lower between them.
That changes the wall cabinet order. A microwave wall cabinet, sized to sit above the range, drops out, and the flanking cabinets may change height to meet the hood’s crown line. Stained in the same finish, the hood shell, the flanking uppers and the crown read as one piece of joinery, which is the look a combo tower makes possible. The wall cabinets are on the wall cabinets page; send us the cooktop and hood choice with the tower and we will draw the whole wall together.
Link four: the counter you get back, and the power it all needs
If a countertop microwave used to live beside the range, it moves into the tower and gives back a stretch of prep counter. In a small kitchen that alone can justify the tower.
The electrical plan changes too. The wall oven usually needs its own dedicated circuit, the microwave in the tower needs a suitable outlet in the right place, the cooktop has its own supply (a gas line or a heavy electrical circuit), and the hood blower needs power at the top of the chimney. None of that is a cabinet question, but all of it has to be planned before the cabinets are set. Bring your electrician the appliance installation guides early.
Is the chain worth it?
For a kitchen that is being fully redone, often yes: the oven moves up to a comfortable height, the microwave comes off the counter, the cooktop gets drawers beneath it and a hood above it that actually clears the air. For a kitchen that is only getting new cabinets around the existing range, the chain is a large change for one tower, and a range with a proper hood above it may give most of the benefit for less.
If you want two ovens rather than an oven and a microwave, the double oven cabinet is the tower for that; a single oven goes in the oven cabinet. Pantries that share the tall wall are on the single door and double door pantry pages. The finish is in the collection, and a free 3D design will lay out the whole chain, tower, cooktop, drawers and hood, in your room before anything is ordered.
Common questions
- What changes when you replace a range with a wall oven and cooktop?
- The oven and microwave move into a tall combo tower, the burners become a cooktop set into the counter, the space below becomes drawers or a base cabinet, and the space above can take a proper range hood instead of an over-the-range microwave.
- What cabinet goes under a cooktop?
- Usually a wide drawer base for pots and pans; in this finish GH DB30-2 is $835.25 and GH DB36-2 is $1,017.25. Check the cooktop’s installation guide for the depth it needs below the counter, since that can limit the top drawer.
- Does a wood range hood need a separate blower?
- Yes, for a vented hood: the shell and the blower insert are sold separately. Blowers in this line are 250, 400 and 600 CFM; the 250 is not offered for the 48″ RHA483021. Where ducting is not possible, the RHBB DCT kit converts the insert to recirculating use with a charcoal filter.
- Is a combo oven cabinet worth it?
- In a full remodel it often is, because it improves the oven height, clears the counter and lets the cooktop have a real hood. If only the cabinets are changing and the range stays, the whole chain may be more change than the kitchen needs.
- How high should a range hood be above a cooktop?
- The insert guide matching Fabuwood’s 400 and 600 CFM blowers puts the bottom of the hood between 24″ and about 30″ above the cooktop, and many gas cooktop manuals require at least 30″; use whichever is higher. The flanking wall cabinets are then set to line up with the hood.
- How much is a Galaxy Horizon combo oven cabinet?
- GH OC3384C is $1,677.00, GH OC3390C is $1,755.00, GH OC3393C is $1,758.25 and GH OC3396C is $1,836.25. All are 33″ wide and ship assembled.
