Most homeowners with basic DIY skills install the Sero in 2-4 hours with a helper. The kit includes a printed step-by-step guide, a 12-minute install video (QR code in the box), and free phone, text, and video support 8am-5pm ET, 7 days. The trickiest single step is lifting the glass panel into place - plan for two people.

Drill (with carbide masonry bit for tile), 4-foot level, tape measure, silicone caulk gun, painter's tape, Phillips and flathead screwdrivers, rubber mallet, and a helper. The kit includes all anchors, screws, seals, and the install template. No specialty tools required.

First-time installers average 2 to 4 hours from unboxing to first water test, including silicone application. Add 30 to 60 minutes if you're drilling through tile or replacing previous hardware. Plan 24 hours of silicone cure time before the first shower.

Yes - tile is the most common install scenario. Anchor through tile into wall studs or solid blocking using carbide-tipped drill bits on low speed. Confirm there's stud or blocking at the mounting points before drilling. Wavy tile or out-of-plumb walls add 30 to 60 minutes but require no tile work on your end.

Tempered glass cannot be recut, so we don't accept returns on cut-to-size kits - but we'll work with you. Call our DIY line use the size dropdown to switch to an in-stock size that fits.

A helper is strongly recommended for the Sero install - specifically for the glass-setting step (lifting and aligning panels into the hinges or track). Everything else (measuring, drilling, anchoring, sealing) is solo-friendly. Total time with a helper: 2 to 4 hours. Solo with workarounds: 4 to 6 hours.
