Rubi 3/16" Leave-In Tile Spacers (400 pc) — Grout a Day Sooner

Pulling spacers is a return trip and a time sink — and a tile that's drifted before you got back to it. These Rubi 3/16" leave-in spacers skip that step entirely. The leave-in design means you can grout right over them, so you grout a day earlier with no second visit to yank spacers out of a floor full of tile.

Beyond the time savings, they do real structural work: rigid plastic holds the tiles in position against floor contraction, helping prevent grout cracks down the line. They're calibrated with clean, uniform edges and built hard enough to hold against the weight of the tile, and this pack gives you 400 pieces to keep a floor moving. A trusted, simple way to set consistent joints and get to grout faster.

Why Tile Pros Choose It

• Grout a day sooner: Leave them in and grout over — no return trip
• Prevents grout cracks: Holds tiles against floor contraction
• Consistent joints: Calibrated 3/16" size with clean, uniform edges
• Rigid build: Hard plastic holds against the weight of the tile
• Big pack: 400 pieces to keep a floor moving
• No spacer-pulling: Skip the most tedious step of the set

Pro tip: Set them upright in the joint so they sit below your grout depth, and confirm your grout joint is deep enough to fully cover them. They're for floors where they'll stay buried — on anything where a spacer might telegraph through, use a removable spacer instead.
