Learn how to attach a groundsheet to your Plex tent bathtub floor using the Groundsheet Attachment Kit. Step-by-step setup, common mistakes, and tips for a secure ultralight shelter.

Quick answer

Attach your groundsheet to your Plex tent by using the Groundsheet Attachment Kit: clip the elastic loops onto your tarp's attachment points and connect them to the bathtub floor's edges. This keeps the groundsheet from shifting or blowing away.

Why attachment matters for Plex shelters

Plex tents rely on a bathtub floor to keep you dry from ground moisture. Without a secure connection, the groundsheet can slide out of place or flap in the wind, compromising protection and comfort. The Groundsheet Attachment Kit provides a simple, lightweight solution that integrates with your existing tarp or shelter.

When to use the kit vs. other methods

The Groundsheet Attachment Kit is ideal if you already own a compatible bathtub groundsheet and a tarp with attachment points. It's lighter and more adjustable than sewing or using clips. However, if your tarp lacks loops or your groundsheet doesn't have matching edges, you may need to add aftermarket tie-outs or consider a different groundsheet.

Steps to attach your groundsheet

Lay out your groundsheet and tarp: Pitch your tarp first, then place the bathtub groundsheet inside, aligning its edges with the tarp's attachment points. Check that the groundsheet is centered and the bathtub walls are upright before attaching.
Identify attachment points: Locate the loops or tabs on your tarp and the corresponding edges on the groundsheet. The Groundsheet Attachment Kit's elastic loops are used to connect these points. If your tarp lacks loops, you may need to add them or use a different attachment method.
Connect the elastic loops: Thread each elastic loop through the tarp's attachment point and hook it onto the groundsheet's edge or grommet. Start with the corners to evenly tension the groundsheet. Avoid overstretching the loops; they should hold the groundsheet taut but not distort its shape.
Adjust tension and position: Fine-tune the loops so the groundsheet lies flat and the bathtub walls stay upright. Ensure no part of the groundsheet is bunched or twisted. A properly tensioned groundsheet should not sag or pull the tarp out of shape.
Test for security: Gently tug on the groundsheet to confirm it stays in place. If it shifts, recheck each loop and tighten as needed. In windy conditions, double-check that all loops are engaged and the groundsheet is fully secured.
