Does Extended Slabs+ work with Fabric, or is it Forge only?

The downloads listed here are for Forge and NeoForge. Check the mod's CurseForge or Modrinth page to see if a Fabric version is available for your specific version.

Can I place vertical slabs next to regular horizontal slabs to make a full block?

Yes, vertical slabs work the same way regular slabs do. Place two vertical slabs of the same type in the same block space and they'll combine into a full block.

Will this mod work alongside other building mods?

Generally yes. Extended Slabs+ is a fairly lightweight block-addition mod and doesn't conflict with most others. If you run into issues, check if both mods are on the same loader version.

Does this add vertical slabs for modded materials, not just vanilla ones?

The mod adds vertical slabs for all vanilla slab types and also supports slabs from select popular mods. Not every mod is covered, but common building mods are included.

I downloaded the mod but the new blocks don't show up. What's wrong?

Make sure you downloaded the version that matches your Minecraft version exactly, and that Forge is installed and selected in your launcher profile. The mod file needs to be in the .minecraft/mods folder, not the main .minecraft folder.

Extended Slabs+ Mod (1.20.1, 1.19.4) - Vertical Slab Blocks

Extended Slabs+ fixes one of Minecraft’s most annoying building limitations: you can only place slabs horizontally. This mod adds vertical slab variants for every vanilla slab type, plus corner blocks and new materials like wood, mud, tuff, and dripstone. If you build anything more detailed than a box, you’ve probably wanted this mod.

What This Mod Adds

The core feature is simple. Every slab in vanilla Minecraft gets a vertical counterpart. That means stone slabs, oak slabs, quartz, brick, the lot. You can now place them upright, which opens up a ton of options for walls, columns, pillars, and cleaner edges on curved builds.

Block Types Added

Vertical slab variant for every vanilla slab material
Corner slab blocks for angled and rounded construction
New slabs for wood, mud, tuff, and dripstone blocks
Support for slabs from select popular mods

The mod is actively updated, so more additions are likely. It’s been around for a while and has gone through a lot of revisions to get to where it is now.
