Slabs are half-versions of their respective blocks.

Obtaining

Stone-type slabs and smooth blocks require a pickaxe to mine. Wooden slabs can be mined with anything, but an axe is quickest.

Natural generation

Smooth stone slabs can be found naturally in villages lining the roof of plains weaponsmith shops and inside the Plains Butcher Shop where they form counters. They are also found in strongholds where they are used in some of the stairs, ledges and torch pillars. Sandstone slabs can be found naturally in desert villages, desert wells, and desert pyramids. Double stone slabs can be found in villages, in the butcher's shop and in blacksmiths. A spruce wood slab serves as a table in igloo basements. Oak, birch, spruce, stone and cobblestone slabs can also be found in mansions.

Dark Oak, Cobblestone, and Mossy Cobblestone slabs generate in pillager outpost.

Smooth sandstone slabs generate in desert village.‌^{[BE & JE only]}

Stonecutting

Petrified Oak Slabs are the stone-type wooden slabs left from before Java Edition 1.3.1. They are now unobtainable in vanilla survival.

Usage

Placement

Slabs can occupy either the top half or the bottom half of a block, or both:

• Placing a slab on top of a block or on the side of a block in the lower half of the side surface will create a bottom slab
• Placing a slab on the underside of a block or on the top half of the side surface will create a top slab
• Placing a top and bottom slab of the same type in the same block will create a double slab block

Slabs cannot be oriented vertically.

Behavior

An example of how top slabs can make redstone travel compactly "up stairs".

Slabs do not block a vertical redstone connection as it is a transparent block.

Double slabs are handled as a single block instead of two different slabs; as such, breaking one will destroy the whole block and drop two slabs, as opposed to only breaking one slab within the block. "Double slabs" that are not aligned to the grid (i.e. a bottom slab on top of a top slab) are handled as separate blocks and are broken individually.

Redstone dust can be placed on a top slab, not a bottom slab. Redstone dust placed on a top slab receives signals from redstone dust one block lower and adjacent, but cannot transmit signals down to that block.

Mobs see a slab as a full block. Mobs can spawn on top slabs and double slabs, but not on bottom slabs. In Bedrock Edition iron golems will not spawn even on a top slab.

In Bedrock Edition, mobs standing on bottom slabs with air or another bottom slab below fail to pathfind correctly. They often end up spinning around in a small circle when they try to move.

Due to the way blast rays propagate from an explosion, bottom slabs provide extremely effective absorption to explosions directly on top of them.

Sneaking only reduces the player's hitbox height to 1.65 blocks in Bedrock and Legacy Console editions, and so does not allow the player to walk over a bottom slab with one block of air above it, which is 1.5 blocks of space. In Java Edition, however, a crouching player's hitbox is exactly 1.5 blocks, allowing the player to fit through such a gap. A player cannot walk from a block of soul sand directly up to a bottom slab without jumping – this applies not just to soul sand, but to any block ⁷⁄₈ of a block high or shorter, because the maximum step height of the player is 0.6 of a block. The player can walk off a bottom slab while sneaking, because the sneaking only prevents falling when the distance is higher than one half block.

If a slab is placed in a water source block, the empty half of that slab's block will be waterlogged. If a top slab is placed in flowing water, a pocket of air is created in the bottom half of the block. In this pocket, the player can breathe and see as clearly as from an air block.

Minecarts on powered rails will not be repelled from a slab. They will, however, be repelled by a slab with a minecart on top.

Falling block entities (like sand, gravel, and concrete powder) will turn into their dropped form if they land on a bottom slab, as when they fall on a torch.

Slabs do not block light in Bedrock Edition.

Fuel

Wooden slabs can be used as a fuel in furnaces, smelting 0.75 items per slab in the Java Edition and Legacy Console editions, and smelting 1.5 items per slab in Bedrock Edition.

Petrified Oak Slab

Petrified Oak Slabs are actually stone slabs with the wooden texture, so they have the same hardness as their stone counterparts. Currently, there are no crafting recipes for this special type of slab, and it can only obtained from the creative inventory or from commands.

History

Java Edition pre-Classic
May 16, 2009					Notch mentions wanting to add "half-height tiles for stairs".
Java Edition Classic
May 17, 2009					Slabs were suggested on the TIGSource forums.
October 22, 2009					Dirt slabs were shown in a blog post.
October 23, 2009					Notch says the new half block has nearly been finished and gives a video.
0.26 SURVIVAL TEST					Stone slabs have now been introduced to the game.
					Stone slabs can be obtained by mining coal ore because of the lack of inventory and crafting.
					Slabs were originally called stairs.
Java Edition Indev
0.31		20100129			Slabs have now received a crafting recipe: 3 slabs from 3 cobblestone.
					Slabs are now no longer dropped from coal ore.
Java Edition Infdev
20100629					Renamed stairs to slabs.[verify]
Java Edition Beta
1.3					Added sandstone, "wooden" and cobblestone slabs as variants of the stone slabs. All had the same properties as stone slabs, apart from using different textures.
					The original wooden slabs have to be mined with a pickaxe to collect, were not affected by fire, and had stronger blast resistance than planks, making them a useful building material. On current versions, this slab can be obtained from the Creative inventory or by using commands. The item tooltip will now say "Petrified Oak Slab" rather than "Oak Slab".
					Before the additional slabs were added, a double stone slab would only yield one slab when broken. Since this update, all double slabs will now yield 2 of their respective single slabs when broken. Destroying double slabs with TNT, however, still only yields single slabs (when the slabs aren't simply destroyed by the explosion).
					Before Beta 1.3 came out, stone slabs were made with cobblestone instead of stone, but this update has now introduced cobblestone slabs to the game and changed the recipes for pressure plates and stone slabs, so that there wouldn't be any conflicting recipes.
1.7					Bottom slabs will now use the bottom half of the double slab texture rather than the top.
					The texture of the cobblestone slab has now been updated.
1.8		?			Added the stone brick, bricks, and smooth stone double slab. (Smooth stone double slab are only obtainable through inventory editing.)
					The sprinting feature has been added in this update. While stairs will cancel the player's sprinting, slabs allow a player to continue sprinting.
Java Edition
1.0.0		Beta 1.9 Prerelease 5			The textures of bricks and planks have now been updated, and by extension that of the slabs.
1.2.1		1.2-pre			All types of slabs are now able to be placed upside down and under blocks; these occupy the top half of their block space rather than the bottom half.
					The crafting recipe has now been changed, so that 6 slabs would be crafted rather than 3. The prior restriction was likely due to the fact that the slab types were differentiated by their damage values instead of by different data values, similar to wood, coal or charcoal, and colored wool.
1.3.1		12w17a			New slabs have now been added for the four different types of wood planks, replacing the old wooden oak/"stone" slab. These new slabs are vulnerable to fire, and can be collected faster with an axe than with a pickaxe. Wooden slabs already crafted or placed in the world will remain the old 'stone' type.
		12w21a			Sandstone slabs will now generate in desert temples.
		12w25a			Redstone (including repeaters, torches. levers and pressure plates) and rails can now be placed on slabs and stairs positioned upside down.
		12w26a			Mobs can now spawn on upside down slabs.
1.4.2		12w39a			Slabs will now interact properly with lighting.
					When slabs are placed upside down, they will now accept light from light sources themselves, and no longer block light to surrounding blocks.
					Slabs will now no longer cast the shadow of a full-sized block.
1.4.6		November 28, 2012			Jeb tweeted a picture of himself crafting nether brick slabs.
		12w49a			Added nether brick slabs, which has now caused the smooth stone double slab to change its data value to 43:7.
1.5		January 22, 2013			Jeb states that the "smooth stone full half-slab" will be re-implemented with a data value of 43:8. Other slabs with data values of 43:9-43:15 will also use the top texture on all sides, resulting in a "smooth sandstone block" with a data value of 43:9. He also stated that they may be obtained legitimately later.
		13w01a			Wooden Slabs can now be used to craft daylight sensors.
		13w02a			Added quartz slabs, featuring the top quartz texture on all six sides. The formerly unused slab type, known as the smooth stone slab, has now been removed from the game. Its data values have been replaced with the nether quartz slab.
		13w04a			The smooth stone double slab has now been re-implemented with a data value of 43:8.
					The smooth sandstone double slab has now been added, with a data value of 43:9.
					Seamless data values of 43:10-43:15 have now been added, but are unused and appear identical to their normal counterparts.
		13w09c			Quartz slabs and double slabs will now use the top, side and bottom textures of the block of quartz.
					The quartz slab's seamless counterpart, with a data value of 43:15, retains the top texture on all 6 sides.
		?			The texture of sandstone slabs have now been changed slightly.
1.7.2		1.7-pre			Added acacia and dark oak slabs.
1.8		14w02a			Stone brick slabs can now be used to craft chiseled stone bricks.
					Stone slabs can now be crafted using granite, diorite, andesite, or their polished counterparts.
		14w25a			Double stone slabs and double wooden slabs can now no longer be obtained as an item.
		14w32a			Added red sandstone slabs and double slabs, as well as smooth red sandstone double slabs.
					Armor stands are now crafted using any slab.
		14w32b			Armor stands can now only be crafted using stone slabs.
		14w33a			Stone slabs can now no longer be crafted using granite, diorite, andesite, or their polished counterparts.
1.9		June 22, 2015			Jeb reveals purpur slabs on Instagram, with the words "MINECON 2015 HYPE!"
		15w31a			Added purpur slabs and double slabs.
		15w43a			A spruce slab will now act as the middle of a table generated within igloo basements.
1.11		16w39a			Oak, birch, spruce, stone, and cobblestone slabs will now generate in woodland mansions.
April 17, 2018					Dinnerbone confirms that Java Edition 1.14 will contain many new stairs and slabs.
1.13		17w47a			The different variant block states for stone_slab, stone_slab2, wooden_slab, purpur_slab, double_stone_slab, double_stone_slab2, double_wooden_slab and purpur_double_slab IDs have now been split up and merged into their own IDs depending on variant.
					Old non-flammable wooden slabs, which are now called "Petrified oak slabs", have been re-implemented into the creative inventory.
					"Bricks slab" has now been renamed to "Brick slab".
					"Stone bricks slab" has been renamed to "Stone brick slab".
					<Wood type> wood slab has now been renamed to <wood type> slab.
					Smooth double slabs, now smooth blocks, have added to the creative inventory. Smooth blocks will now drop themselves, instead of slabs when mined.
					Prior to The Flattening, these blocks' numeral IDs were 43, 44, 125, 126, 181, 182, 204 and 205.
		18w07a			Added slabs for prismarine, prismarine bricks, and dark prismarine.
		18w10c			Water can now be placed on the same block as slabs.
		18w20a			Changed the name of "Prismarine Bricks Slab" to "Prismarine Brick Slab."
1.13.1		18w32a			Purpur slabs can now be crafted with purpur pillars.
October 10, 2018					Dinnerbone tweets that there will be 14 new slabs.
October 10, 2018					Polished diorite slabs are tweeted out by LadyAgnes.
1.14		18w43a			Added andesite, polished andesite, diorite, polished diorite, granite, polished granite, mossy stone brick slab, mossy cobblestone, smooth sandstone, smooth red sandstone, smooth quartz, red nether brick, end stone brick slabs.

Trivia

• Any light directed through a slab does not affect any block's light values north of the source.
• Whereas 1×1 dents in a flat floor using slabs are darkened as one would expect, 1×1 dents created using 2×1 or 2×2 stairs will darken less, due to having fewer surrounding solid blocks.
• When water or lava are on top of an upside-down slab, the water dripping particles will appear in midair below the slab instead of from the slab itself, this was fixed in Java Edition 1.13-pre7, but is an intentional feature in Bedrock Edition.
