Galaxy Indigo diagonal sink front: a navy door on a cavity built from the room

The Galaxy Indigo diagonal sink front, GI DSF36 at $149.50, is an angled frame with a navy shaker door hung in it and no box behind. An installer uses it to close off a corner sink cavity made from the two cabinet runs that meet there. Because there is no cabinet back, the inside of that cavity is the room itself, and most of what goes right or wrong with a navy front is about the surfaces around it.
A navy door in an angled frame, and the $100.75 floor beside it
The 36 in the name is the wall space each leg gives up, the same footprint as the complete diagonal sink base. The front arrives as a finished frame with a full-overlay Galaxy door already hung on Blum soft-close hinges: solid wood frame, ⅜″ MDF centre panel, painted in the same slate navy as the rest of the kitchen. Nothing else is in the carton.
GI DSFL36, the matching 36″ diagonal sink floor, is a separate line at $100.75. Front and floor together are $250.25, against $617.50 for the complete corner cabinet. The floor gives the cavity a finished deck to stand bins and a tray on; ask your designer to confirm what its carton contains before it ships.
People who order this part on purpose usually have one of two reasons. The bowl they want is too large for the factory corner box, and a cavity built from two full runs gives it more room; or they are a builder who sets corners this way on every job and wants only the navy face from us. If neither applies, the complete cabinet is simpler and the rest of this page does not concern you.
Open the door and you are looking at the wall
A factory sink base has a veneered interior. A site-built corner does not: the two sides of the cavity are the outside faces of the flanking cabinets, and the back is whatever the wall is, usually bare drywall with the plumbing coming through it. Every time the navy door opens, that is what you see, and it sits in the wettest spot in the kitchen.
Treat it as a surface, not a leftover. Before the front goes on, patch the holes around the stub-outs, prime the drywall with a moisture-resistant primer and paint it in a scrubbable finish. A light colour works best in there, because a pale back wall shows a drip or a stain at a glance behind a dark door where a navy interior would hide it. Seal around the supply and drain penetrations so a leak cannot run into the wall cavity.
Every surface a navy corner shows, and where each one comes from

A navy run is unforgiving of anything in another colour: a white toe kick or a raw plywood filler reads as a stripe from across the room. List every visible surface of the corner and make sure each one is either factory Indigo or deliberately something else.

The fillers, toe kick and scribe are on the decorative accessories page; the flanking cabinets come from the base range. Our guide to end panels, fillers and scribe molding explains where each one goes.
Why an opaque navy is forgiving at a cut edge
Every site-built corner involves cutting: fillers ripped to width, a toe kick mitred across the angle, a scribe shaped to the wall. Each cut exposes a pale edge, and against navy a pale edge is obvious. The good news is that Indigo is a flat, opaque paint with no grain showing through, so there is no wood pattern to match. A careful coat from the matching touch-up kit, GIN-TOUCH-UP-KIT at $62.40 on the loose parts page, blends a cut edge more completely than it would on a stained finish.
Colour every cut edge before the part is fastened, when it can be done flat on a bench. Edges that face the floor or the wall can be left, but anything visible from the room should be finished.
When a finished cabinet is the better order
If the corner does not need a site-built cavity, the complete diagonal sink base at $617.50 arrives with its own veneered interior and deck and skips everything above. A sink on a straight wall goes in a sink base from $386.75, and an apron-front sink in a farm sink cabinet from $806.00. The wall cabinets and the lighter finishes that pair with this navy are in the Galaxy Indigo collection.
Common questions
- Is the diagonal sink front a whole cabinet?
- No. GI DSF36 is an angled frame with the navy door already hung, at $149.50. The cavity behind it is built on site from the two flanking cabinet runs. The complete corner cabinet is GI DSB36 or DSB36FD at $617.50.
- What colour should the inside of a site-built corner sink be?
- A light, scrubbable paint over a moisture-resistant primer. The back of the cavity is usually bare drywall, and a pale finish there makes any drip or stain easy to see behind the dark door.
- Do I need the DSFL36 floor?
- In most corners, yes. GI DSFL36 at $100.75 gives the cavity a finished deck. Without it the floor is whatever the room has. Ask your designer to confirm what the floor carton contains.
- Can I touch up a cut edge on a navy cabinet part?
- Yes. Indigo is an opaque paint with no grain to match, so the matching touch-up kit, GIN-TOUCH-UP-KIT at $62.40, blends cut edges well. Finish each edge before the part is installed.
- Which navy trim pieces does a site-built corner need?
- Usually a toe kick (GI TK8, $55.90 per 8 ft), base fillers (GI BF3 at $26.00 or GI BF6 at $43.55), scribe molding where a wall is uneven (GI SM8-S, $39.00) and a base end panel (GI BEP, $149.50) on any exposed end.
- Is front plus floor cheaper than the complete corner cabinet?
- On the parts alone, yes: $250.25 against $617.50. Add the trim, the site labour and the painting of the cavity and the gap narrows. Build the corner on site when the factory box will not suit the sink, not only to save money.
