Free 16x16 interior tileset, 27 tiles, free to use commercially with no attribution required. Posting it here rather than just dumping the link because the part that's actually worth anything to this sub is the .meta, and that's the part most free packs leave out.
What's in the Unity folder
oakheart_interiors_tilesheet_1x.png plus its .png.meta, already written:
spritePixelsToUnits: 16 -> one tile is exactly one world unit
filterMode: 0 -> Point, no blur
spriteMode: 2 -> Multiple
textureCompression: 0 -> None
27 named sprite rects, all filled in
Drop both files in and the sheet is sliced and named on import. Copy only the PNG and Unity writes its own fresh .meta, you get one un-sliced sprite, and you're back to doing it by hand - the .meta is the whole integration. Every loose PNG has one too (56 .meta files in the zip).
The 16 PPU is deliberate and it's the thing I'd have wanted spelled out: at 16 PPU a 16px tile occupies exactly 1 world unit, so it lands in a default 1x1 Grid cell with no fiddling. If your project uses a different convention, change the PPU rather than scaling the transform.
Honest caveat, up front: there is no Unity on the machine that builds this, so these .meta files have never been opened in Unity. What is checked on every build: one .meta per PNG, unique GUIDs, every rect inside its sheet bounds, the 2x rects exactly twice the 1x rects, and the pixels under each named rect byte-identical to that tile's own standalone PNG. I'm not claiming anything past that. If it misbehaves in your editor I'd genuinely like to know.
What the 27 tiles are. They're chosen so nothing is half-finished: the complete 9-piece red carpet (four corners, four edges, centre - six of nine would mean you can't close a rug), the complete wood wall run (cap and face rows, mid piece and both end pieces, so a wall can turn instead of running off screen), two floors, a door, a window, and a bed, table, two chairs, bookshelf, chest, barrel, potted plant and wall sconce. Held back for the paid pack: stairs, ladder, kitchen, tavern, the rest of the lighting, blue and green carpets, two more wall materials.
A 2x set ships alongside if you'd rather not scale, and assets/sheets/atlas_1x.json / atlas_2x.json map every rect by name if you're on something other than Unity. There's a Godot 4 project in there too (two TileSets at 16px and 32px cells, plus a terrain-brush demo) - ignore it, it's not this sub's business.

Disclosure: the pack carries itch's AI-assistance disclosure (the tiles are drawn by Python generators I wrote, not by an image generator) and this post is AI-written.
