Measuring guide

How to measure your opening

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.

1

Width at three heights

Measure across the top, middle, and bottom. Use the smallest value - a 1/4" variation top to bottom is normal.

2

Height for the header

Measure from the curb or shower floor up to where the top roller-bar header will mount. This sets the panel height.

3

Check walls for plumb

Hold a level against each side wall. Minor lean is absorbed by the install; a severe lean is worth a pro measurement.

4

Confirm curb or floor

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

Installing your Luna kit

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.

  1. 1

    Mount the roller-bar header and bottom guide

    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.

  2. 2

    Hang both panels on the roller bar

    Lift each 3/8" glass panel and seat its rollers onto the exposed header so the two panels bypass each other freely.

  3. 3

    Adjust the glide and clearance

    Fine-tune the roller height so both panels hang plumb, slide with one-finger pressure, and clear the bottom guide evenly.

  4. 4

    Attach the dual towel bars

    Fit the full-width towel bar onto each sliding panel and snug the through-glass fittings - one bar per panel, standard on Luna.

  5. 5

    Seal and cure

    Run the vertical seals and bottom sweep, silicone the wall joints, and let it cure 24 hours before the first shower.

Q&A

Frequently Asked Questions

How hard is the Luna DIY install?

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.

What tools do I need?

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.

How long does the Luna install take?

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.

Will the Luna work on my tile or stone walls?

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.

What if I order the wrong size?

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.

Can I install solo or do I need a helper?

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.

How long does shipping take?

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.

Do you ship to all 50 states?

Yes - standard ground shipping to all 48 contiguous states. Alaska and Hawaii are available with a freight surcharge; contact us for a quote.

What if my package arrives damaged?

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.

What's the price difference between DIY and Install?

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).

Are there bulk or contractor discounts?

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.

What's the DIY warranty?

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.

Can I upgrade to professional install later?

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).

Where can I find install videos?

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.

Can I call for help during 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 vs. 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.
