Galaxy Linen sink base cabinets: budget the space under the sink before you pick a width
Reviewed September 2026 · Captivating Cabinets
Open the door on a Fabuwood Galaxy Linen sink base cabinet and you are looking at the one box in the kitchen that is mostly empty on purpose. Ten widths from 21″ to 42″, all 34½″ high and 24″ deep, priced $386.75 to $572.00 — and the figure that decides which one to order is not the length of the wall but the sum of everything that has to live behind that door.
What size sink base for a 33-inch sink? Add up the bay before the width

Most people size this cabinet by subtraction: the wall is so long, the range and the fridge take so much, and the sink gets what is left. That produces a 30″ box more often than not, which is fine for a bowl on its own and stops being fine the moment a disposal goes under one side of it and a filter or a trash pull-out wants the other. Coming at it from the sink end is better — a 33″ bowl sends most shoppers looking for a 36 inch sink base cabinet, which is the right instinct — but it still leaves out everything else that has to share the bay.
So budget it the other way. The interior is close to an inch narrower than the nominal width, because each side panel is ½″ thick; the face frame opening is narrower again, and that opening is what any bin or tray has to pass through before it can share the bay with the trap. A trade rule of thumb: take three inches off the nominal cabinet width and that is the widest bowl that will drop in without a fight.
| What goes under the counter | Comfortable box | SKU | Price today |
|---|---|---|---|
| Bar or prep bowl, no disposal | 21″ or 24″ | GL SB21 / GL SB24 | $386.75 / $403.00 |
| One 25″ bowl and a trap, nothing else | 30″ | GL SB30 | $461.50 |
| That bowl plus a disposal | 33″ | GL SB33 | $468.00 |
| Bowl, disposal and a pull-out bin | 36″ | GL SB36 | $490.75 |
| Double bowl, disposal and a filter tank | 39″ or 42″ | GL SB39 / GL SB42 | $526.50 / $572.00 |
These are planning allowances, not manufacturer clearances; the final check is the sink maker's template laid over the face-frame opening. Undecided between two widths? The wider one costs $6.50 to $45.50 more on this page and never gets regretted. GL SB27 at $442.00 fills the gap for a 24″ bowl with a disposal. Every width arrives assembled, with the Blum soft-close hinges already hung, so there is no flat-pack step between delivery and the plumber. For a bathroom, look at the vanity sink bases instead — they are shallower and lower.
What the false front is covering
The panel across the top of every one of these units does not open. Behind it are the underside of the bowl and the rim clips, which is why there is no drawer and no shelf: the bay is left clear so the trap can drop where the sink puts it. The panel is the same five-piece recessed front the drawer bases use, so on a run of this beige the shadow line of rail and stile carries across the sink without a break.
That continuity is why the SDF versions exist. At 33″ and 36″ the false front can be one uninterrupted panel — GL SB33SDF and GL SB36SDF, at the same $468.00 and $490.75 as the split versions. The neighbour decides: a three-drawer base has a single top drawer, so a single false front beside it keeps the line unbroken; two door bases with paired fronts want the split version. Read it off the elevation, not the price list.
If a blind panel bothers you, a tilt-out tray turns it into a sponge holder. Bins and trays that can share the bay are on the accessories page; our guide to pull-out organizers sorts the door-mounted ones from the floor-mounted.
The plumbing wall: four measurements to write on the plan
Galaxy ships assembled, so the back of this box gets hole-sawed on install day to suit whatever the plumber left in the wall. What you can control is where those stub-outs land. Four numbers, taken before the cabinet is set, prevent almost every sink-day surprise:
- Drain centre: height off the finished floor and distance from the nearest wall or cabinet end. It has to fall inside the footprint and high enough for the trap to clear the deck.
- Supply stops: both, same two references. A stop behind a side panel means notching the box on site.
- Disposal power: the outlet or switched leg, and which side of the bowl the disposal hangs on. That side of the bay is spoken for.
- Dishwasher tie-in: the drain hose and supply cross in from next door through a side panel. Decide which side the dishwasher is on now, because the hole goes in that panel.
The hinges are Blum Quick-Release, so the doors lift off without tools — have the plumber take them off rather than work around them. Our kitchen dimensions checklist lists the rest of what to measure before ordering.
The deck under the trap is the part that ages first

A ½″ solid wood box, a veneered interior and a limited lifetime warranty are none of them a defence against a weeping compression fitting. Every other cabinet in the kitchen is dry; this one has three joints, a disposal gasket and a dishwasher hose in it, and it is opened for the trash bag and nothing else.
Three habits keep the deck out of that photograph. Put a moulded tray with a raised lip on the floor of the cabinet before anything else goes in, so a leak pools where you can see it instead of soaking into the veneer. Do not pack the bay to the brim — leave enough clear deck that a stain shows from the doorway. And if the worst happens, Fabuwood's Linen is a catalog finish rather than a custom match: a single replacement GL SB box lands the same beige as the ten-year-old cabinets on either side of it.
Our piece on how long cabinets last ranks which components go first and why this cabinet leads that list; the cabinet care guide has the wipe-down routine for a painted door around a wet zone.
Sink base, farm sink, diagonal base or diagonal front: which listing fits your sink
For a top-mount or undermount bowl on a straight wall this page is the end of the search. Three other listings in the same beige cover the sinks it cannot take.
| The sink | The listing | Price | Where people go wrong |
|---|---|---|---|
| Drop-in or undermount bowl on a straight run | This page — GL SB21 to GL SB42 | $386.75 – $572.00 | Matching the cabinet width to the bowl instead of clearing it |
| Apron-front (farmhouse) sink | Farm sink cabinet | $806.00 – $825.50 | Trying to cut a standard base down for it |
| Bowl in a corner, complete cabinet wanted | Diagonal sink base | $617.50 | Setting the dishwasher tight against it |
| Bowl in a corner, cavity built on site | Diagonal sink front | $149.50, plus $100.75 for the floor | Expecting a cabinet to arrive |
If none of the rows is obviously yours, a free 3D layout settles it before anything ships. The bases that flank this one are under base cabinets; the rest of the room is in the Linen collection.
Common questions
- What size sink base cabinet do I need for a 33 inch sink?
- A 36″ box — GL SB36 at $490.75 — is the safe answer, and it leaves one side of the bay for a disposal. The interior is about an inch under nominal because each side panel is ½″, and the face-frame opening is narrower again, so lay the sink template over the opening rather than trusting the three-inch rule alone.
- Can I put a pull-out trash can in a sink base?
- Yes, on one side of the trap, and only if there is a side left after the disposal. In practice that means a 36″ box or wider — bowl on the centre, disposal on one side, bin on the other. On a 30″ unit something has to give.
- What is a sink base with a single drawer front (SDF), and do I need it?
- SDF means the false front across the top is one continuous panel instead of two. Order it only if the cabinet beside it has a single-panel top drawer, such as a three-drawer base; it costs the same as the standard unit and exists at 33″ and 36″ only.
- What countertop goes with beige cabinets at the sink?
- Something warm. Cream quartz, butcher block, travertine or a stone with beige veining keep this finish looking creamy; a cool gray quartz next to it makes the beige go muddy, and the sink wall is where you would notice. Test a door sample against the counter sample in daylight.
- Does the sink base come with a shelf?
- No. The bay is open from the false front down to the deck so the bowl and the trap can drop in wherever the sink puts them. Storage inside comes from a floor-mounted tray or a door-mounted rack, not from a shelf.
- How much is a 30 inch sink base cabinet, and does it come assembled?
- GL SB30 is $461.50, and like every Galaxy cabinet it arrives assembled — dowel-and-glue and pocket-screw joinery, Blum soft-close hinges already hung. The full range on this page runs from $386.75 for the 21″ unit to $572.00 for the 42″, with the same ½″ solid wood box at every width.
