Why Mona
Why Mona Is the Best Bypass Shower Door
Built for homeowners who want a clean semi-frameless look, flexible glass options, and a smoother professional installation. It combines practical adjustability, stocked availability, and a polished custom-style finish.
Removable Side Jambs for Better Shower Door Alignment
Mona's removable aluminum side jambs help installers square and align the shower door, especially on out-of-plumb walls and remodel openings.
Semi-Frameless Bypass Design with Dual Towel Bars Included
Mona has a clean semi-frameless bypass design with two sliding glass panels, minimal framing, and dual towel bars included standard.
Mona Installation Overview
Mona Double Sliding (Bypass) Shower Door
A semi-frameless bypass shower door with two moving panels, dual-side entry, dual towel bars, and 3/8-inch or 1/4-inch tempered glass.
The only bypass sliding kit we carry in both 3/8-inch and 1/4-inch glass thicknesses, Mona uses two sliding panels, a semi-frameless profile, removable side jambs, and dual towel bars.
Match the wall opening's structural rating and your budget without overspecifying. The 3/8-inch or 1/4-inch tempered glass keeps the panel look clean, while included aluminum wall jambs help true the enclosure on out-of-plumb walls.
All Mona hardware is finish-coated aluminum. Add optional ClearShield coating at order time and the factory-applied hydrophobic layer helps reduce calcium and soap-scum buildup, so cleaning takes a microfiber wipe instead of a chemical scrub.
Why choose Mona with professional install
- Pick the right glass weight. We help you decide between 3/8 inch and 1/4 inch based on wall structure and budget - pros catch issues DIY misses.
- 1-year boxed/3-year custom warranty. In-stock Mona sizes carry 1 year; custom install builds carry 3 years on parts and labor, across both thickness options.
- Removable side jambs aid alignment. Mona's side jambs come off for panel setting, then reinstall - our crew uses them to true the enclosure on out-of-plumb walls.

A soft satin tone that warms Mona's semi-frameless look and hides water spots well on the header rail and towel bars.
Matte Black

Frequently Asked Questions
Common Mona installation questions
Answers to the install, service area, pricing, warranty, and support questions that come up before a Mona project moves forward.
How long does the whole Mona install process take?
5 to 7 days from quote to install. Day 1: phone consultation and same-day quote. Within 3 days: laser-measure visit at your home. Days 4 to 6: custom fabrication. Day 5 to 7: install in your home (typically 1 to 4 hours on-site).
What does the laser measurement visit cover?
A certified team member measures your shower opening with laser precision, captures every angle (out-of-plumb walls are common), confirms hardware mount points, and verifies curb or curbless setup. Free, no obligation, scheduled within 3 days of your quote.
Do you handle removal of my old shower door?
Yes - old door removal and disposal are included with every Mona install. Our team uncrates and removes the old fixture before installing the Mona, then hauls the old door away. No third-party hauler needed.
Can you install Mona on a curbless shower?
Yes - Mona is curbless-installation-ready. Our team handles the floor-mount alignment so the door tracks straight even on curbless setups. If you have a curb, our minimum curb width is 2-15/16 inches.
What's your service area?
Our professional install service covers the Washington DC, Maryland, and Virginia metro area - specifically Manassas, Silver Spring, Arlington, Baltimore, and surrounding communities. Enter your ZIP code in the availability tool above to check if your address qualifies.
What if I'm outside your service area?
If your ZIP isn't covered for pro install, switch to the Mona DIY kit - same glass, same hardware, ships in 2 business days from our warehouses. $300 flat nationwide shipping, or free pickup in Manassas, VA or Baltimore, MD. You install in 2 to 4 hours with a helper. 1-year DIY warranty (vs 3-year for pro install).
Do you install in HOAs, condos, or rental properties?
Yes - we work with HOAs, condo associations, and landlords regularly. We can provide certificate-of-insurance documentation, scheduling around association rules (quiet hours, elevator reservations), and itemized quotes for landlord approval. Let us know up front.
What's the price range for an installed Mona?
Installed Mona typically runs $1,599-$2,099 depending on size, finish, and any premium options. The quote includes glass, hardware, fabrication, in-home install, and old-door removal. Get a same-day quote with no obligation.
Why pay for install vs. doing it myself?
Three reasons: (1) the 3-year full warranty (parts AND labor) vs. 1-year hardware-only on DIY. (2) Custom-fit measurement - no DIY measuring guesswork that can lead to return shipments. (3) Done in one visit by certified installers - most homeowners value the half-day saved over the install premium.
What's covered under the 3-year install warranty?
Both parts AND labor for 3 years from your install date. Tempered glass, hardware, rollers, and the installation workmanship are covered for 3 years. Plastic seals and door sweeps are 1-year wear items handled as yearly maintenance - replacements ship at low cost and a quick look-over each year keeps water where it belongs. If anything else needs adjustment, our installers come back at no charge. Compare to DIY mode, which is 1-year hardware-only.
How do I get a quote?
Call (866) 452-7707 or use the Get Free Quote button. We give same-day quotes by phone - share your opening dimensions, finish preference, and ZIP. If you'd prefer in-person, we visit your home within 3 business days for a free laser measurement.
