How to Make a Water Elevator in Minecraft Bedrock
Ladders are slow. Staircases take up too much space. And falling into your mine shaft hoping you'll land in that one-block water pool at the bottom is not a long-term strategy. Water elevators solve all of this: instant vertical travel, cheap to build, works in any direction, and once set up, never needs maintenance.
The build takes about five minutes and a handful of materials. Here's the full process.
Materials You Need
- Building blocks — glass, stone, whatever you like. Enough to make a column as tall as you want the elevator.
- Soul Sand — one block. Makes the elevator go up. Found in the Nether, especially in Soul Sand Valleys.
- Magma Block — one block. Makes the elevator go down. Found in the Nether, underwater ocean ravines, or ruined portals.
- Kelp — a bunch. Found in any ocean biome. You need one piece per block of elevator height. A 30-block elevator needs 30 kelp.
- Water bucket — one is enough.
- Signs or doors — to hold the water in at the entrance.
You will need Nether access for soul sand. There's no way around it. If you haven't been to the Nether yet, you'll need to build a portal first (10 obsidian minimum, plus a way to light it).
Building the Up Elevator (Soul Sand)
- Build the shaft. Create a 1×1 column of blocks as high as you want the elevator to go. Glass looks great and lets you see the bubbles, but any block works. Leave the inside hollow.
- Make the entrance. At the bottom, create a 2-block-high opening to walk in. Place a sign or open door on the inside of the entrance at the top block. This holds the water in without blocking your path.
- Place a temporary block at the bottom. Put any solid block (dirt, sand, whatever) at the very bottom of the shaft. This is where soul sand will go later, but you need a regular block here first so you can plant kelp on it.
- Fill with water from the top. Go to the top of the shaft and pour your water bucket into the top block. The water will flow all the way down. At this point, the water is flowing, not source blocks. That's the problem kelp fixes.
- Plant kelp from bottom to top. Swim into the shaft, start at the bottom, and place kelp on each block going up. Each piece of kelp converts the flowing water at that block into a source block. This is the key step. Every single block in the column must be a source block or the elevator won't work.
- Break all the kelp. Once you've placed kelp all the way to the top, go back down and break the bottom piece. The whole column of kelp breaks, but the water stays as source blocks.
- Replace the bottom block with Soul Sand. Break the temporary block and place soul sand in its place. You should immediately see a column of bubbles shooting upward. Step in, and you'll be launched to the top.
Building the Down Elevator (Magma Block)
Build a second shaft right next to the first one. Follow the exact same steps as above, but in step 7, place a Magma Block instead of soul sand. The bubbles will pull downward, dragging you to the bottom.
One thing to know: standing on a magma block deals half a heart of damage per tick. You can avoid this by crouching (shift/sneak) when you land on it, or by wearing boots enchanted with Frost Walker. Alternatively, step off the magma block as soon as you reach the bottom.
Why Kelp Matters (And What Goes Wrong Without It)
This is the part that trips up most builders. When you pour water from the top of a shaft, it creates one source block at the top and flowing water below it. Flowing water doesn't create bubble columns. Soul sand and magma blocks only generate bubbles through source blocks.
Kelp converts every flowing water block it touches into a source block. That's its entire purpose in this build. Skip the kelp step and your elevator will just be a column of still water that does nothing.
If your elevator isn't working after building it, nine times out of ten there's a flowing water block somewhere in the column. Place kelp through the entire shaft again, break it, and try again.
Alternative: No Kelp Method
If you can't find kelp (rare, but it happens if you're far from an ocean), there are two workarounds:
Water bucket method: fill multiple buckets with water and place a source block at every single level of the shaft, starting from the bottom. This is tedious for tall elevators but works.
Ice method: collect ice blocks (Silk Touch pickaxe on ice), place them in the shaft, then break them. Each broken ice block becomes a water source block. Faster than individual bucket placement.
Compact Two-Way Design
If you don't want two separate shafts, you can build a single 1×2 shaft with soul sand on one side and a magma block on the other. Step into the soul sand side to go up, step into the magma side to go down. Both columns need their own full set of source blocks, so plant kelp in both sides.
This saves space but can feel cramped. For most builds, two separate 1×1 shafts side by side is cleaner and easier to use.
How Tall Can It Go?
There's no height limit. A water elevator works from Y = -64 to Y = 320 if you want. The bubbles push at the same speed regardless of height. The only limit is how much kelp and building material you're willing to gather.
For very tall elevators (50+ blocks), the kelp step takes a while. Bring extra kelp. If you run out mid-column, you'll need to swim back down, get more, and continue where you left off.
Practical Uses
Mine shaft access. Build a water elevator from your base down to Y = -59 (diamond level). Instant travel that beats any staircase.
Mob farms. Use a magma block elevator to pull mobs downward into a kill chamber, or a soul sand elevator to push items upward to a collection point.
Multi-level base. Water elevators work as floor-to-floor transport inside builds. Connect your storage room, enchanting setup, and farm levels without ladders eating wall space.
Nether hub exits. Place water elevators at each portal exit in the Overworld for quick vertical travel to surface level.
Troubleshooting
"No bubbles appear." There's a flowing water block in the column. Place kelp through the entire shaft again, then break it. Every block must be a source block.
"Bubbles appear but I get stuck halfway." Same issue. One block in the middle is flowing instead of source. Swim to where you're getting stuck and place kelp at that exact spot. Break it and test again.
"Water keeps spilling out of the entrance." Your sign or door isn't placed correctly. Signs should be on the inside of the entrance at eye level (second block up from the floor). Doors work too, just make sure they're open so you can walk through.
"I take damage at the bottom of the down elevator." That's the magma block. Crouch when you land, or replace the floor block next to the magma with a regular block and step off immediately.
"Kelp won't place." Kelp can only be planted on a solid block at the bottom, and each piece places on top of the previous one. You can't place kelp in mid-air or on flowing water without an existing kelp plant below it. Start from the very bottom and work up.
