Crowne Tools Plug-Level — Plug the Drain and Level It in One Move Two things go wrong at the drain during shower prep: debris falls into the plumbing, and the drain ends up out of level — which fights your slope for the life of the shower. The Plug-Level handles both at once. It seals a bonding-flange drain against mud and thinset while a built-in bubble level, right at the drain, confirms the base is dead level before you pack the mud bed. Instead of juggling a makeshift plug and a separate level, this drops into the drain opening and puts the level exactly where alignment matters most. Verify level, then move on to waterproofing and tile knowing the drain won't quietly undercut your slope. It's built from durable ABS for repeated use, job after job. Why Tile Pros Choose It Two jobs, one tool: Plugs the drain and levels it Protects the plumbing: Keeps mud, thinset, and debris out Level where it counts: Built-in bubble right at the drain Bonding-flange fit: Made for bonded shower drains Durable ABS: Holds up to repeated jobsite use Because "I'll eyeball the drain" is how callbacks are born: Confirm it and move on Pro tip: Seat it before any mud or thinset goes down, confirm level in both directions, and leave it in place to keep debris out until you're ready to set the drain finish.
