Pick your thickness.
3/8" for premium feel and weight; 1/4" for lower price and easier handling. Same hardware and 1-year DIY warranty either way.
DIY Kit Overview
Same semi-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 Mona DIY kit is the same semi-frameless bypass slider as our installed builds - two sliding panels with minimal aluminum framing and removable side jambs, plus dual towel bars standard. What makes Mona unique is the choice of glass thickness: it is the only bypass slider we stock in both 3/8" and 1/4" tempered glass, so you can match the glass weight to your wall structure and your budget without overspecifying. Same hardware, same optional factory nano-coating - you just handle the install in 2-4 hours with a helper and save the install premium.
Want the same bypass layout in framed 1/4" only at a lower price? Vera may be the simpler fit.

Measuring guide
Approximate measurements are fine for a quote - but tempered glass can't be re-cut, so if your opening falls between stocked sizes, confirm with our DIY line before you order.
Measure the finished opening across the top, middle, and bottom. Use the smallest value - a 1/4" variation top to bottom is normal.
From the curb or shower floor up to where the top header track 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 track or guide.
Install Notes
Most homeowners install the Mona in 2-4 hours with a helper. Mona is a semi-frameless bypass with removable aluminum side jambs - the jambs come off to set the panels, then reinstall to true the enclosure, which makes the DIY panel set easier. 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 the glass panels onto the rollers.
Anchor the header track and bottom guide to the walls and curb using the included template, with the removable side jambs set in place.
Lift each sliding panel onto its roller assembly in the header track - the two-person step. Both panels glide past each other on the bypass track.
Fine-tune the rollers so both panels run smoothly with an even gap, then reinstall the side jambs to true the enclosure.
Fit the vinyl vertical seals and bottom sweep, silicone the wall and curb joints, and let it cure 24 hours before the first shower.

Project Inspiration
Q&A
Most homeowners with basic DIY skills install the Mona 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 Mona 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.
Yes - standard ground shipping to all 48 contiguous states. Alaska and Hawaii are available with a freight surcharge; contact us for a quote.
Inspect at delivery. If you see crushed corners or visible damage, photograph and refuse the delivery - we replace the kit at no charge. If you discover damage after opening, contact us within 48 hours and we ship replacements in 2 business days.
DIY Mona runs $520-$760; professionally installed runs $1,599-$2,099. 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 Mona 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.
