DIY Kit Overview
Same fully-frameless bypass sliding shower door as our installed builds, shipped flat-pack to your door - same glass, same hardware, same 1-year warranty. Free phone, text, and video DIY support included.
The Luna DIY kit is the same fully-frameless bypass slider as our installed builds - two 3/8" tempered glass panels gliding on an exposed roller-bar header, with no framing around the glass and no wall jambs.

Same glass, same finish-coated aluminum hardware, same factory nano-coating - you just handle the install in 2-4 hours with a helper and save the install premium.

Measuring guide
Approximate measurements are fine for a quote - but tempered glass can't be re-cut, so a custom-fabricated build is the safer path if your opening falls between stocked sizes.
Measure across the top, middle, and bottom. Use the smallest value - a 1/4" variation top to bottom is normal.
Measure from the curb or shower floor up to where the top roller-bar header will mount. This sets the panel height.
Hold a level against each side wall. Minor lean is absorbed by the install; a severe lean is worth a pro measurement.
If your shower has a curb, it needs to be at least 2-15/16" wide to land the bottom guide; for a curbless install, note the floor condition.
Install Notes
Luna is a fully frameless bypass - two 3/8" glass panels glide on an exposed aluminum roller-bar header, with no framed channel and no bottom rail. Most homeowners install it in 2-4 hours with a helper. The rollers are adjustable, so the glide can be trued after the header is mounted. The kit includes a printed step-by-step guide and a QR-code install video - and free phone/text/video support if anything looks off. Plan for two people: the trickiest step is lifting each panel onto the roller bar.
Level and anchor the top roller-bar bracket to the studs or substrate, then set the bottom guide on the curb or floor using the included template.
Lift each 3/8" glass panel and seat its rollers onto the exposed header so the two panels bypass each other freely.
Fine-tune the roller height so both panels hang plumb, slide with one-finger pressure, and clear the bottom guide evenly.
Fit the full-width towel bar onto each sliding panel and snug the through-glass fittings - one bar per panel, standard on Luna.
Run the vertical seals and bottom sweep, silicone the wall joints, and let it cure 24 hours before the first shower.

Project Inspiration
Q&A
Most homeowners with basic DIY skills install the Luna 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 Luna 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.
Ships in 2 business days from our U.S. warehouses. Free pickup at either location. Local delivery within 30 miles is $95. Nationwide shipping is $300 flat per enclosure, anywhere in the lower 48. Standard ground freight runs 3 to 5 business days. Door-to-door is typically 1 to 2 weeks.

DIY Luna runs $570-$630; professionally installed runs $1,599-$1,999. The install premium covers laser measurement, fabrication-to-fit, in-home installation, old-door removal, and the upgraded 3-year parts+labor warranty (vs 1-year DIY hardware-only).
Yes - for orders of 5+ kits, contact us for trade pricing. We also offer Dulles Glass PRO accounts for contractors, designers, and bulk-purchase customers with consistent volume.
1-year warranty on glass, hardware, seals, and finish under normal use. Manufacturing defects are covered. Damage from improper install (over-torqued hardware, wrong anchor for substrate) is not - call our DIY line first if you're not sure.
Yes - if you're in our install service area and the kit is unopened, we'll credit the DIY purchase against an installed quote. Enter your ZIP on the install hub to check coverage, or call (866) 452-7707. Out-of-area orders stay DIY (we don't sub-contract installs nationally).
A step-by-step install video is referenced on the printed instructions (QR code) and on our YouTube channel. The Luna walkthrough runs about 15 to 20 minutes for the full install.
Yes - live phone, text, and video support 8am-5pm ET, 7 days a week. Best to call before drilling permanent holes if anything is unclear.
Compare to Sero
Luna and Sero are both 3/8 inch bypass sliders with dual towel bars. The difference is framing: Luna is fully frameless with an exposed roller-bar header; Sero is semi-frameless with minimal framing and included wall jambs that help on out-of-plumb walls. Luna also adds a Satin Brass finish - four to Sero's three.
