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 tempered glass.

Mona uses two 3/8-inch tempered glass sliding panels, a semi-frameless profile, and dual towel bars.

The substantial 3/8-inch tempered glass gives the panels a solid feel, while included aluminum wall jambs help true the enclosure on out-of-plumb walls.

All Mona hardware is finish-coated aluminum.

Why choose Mona with professional install

  • Substantial 3/8-inch glass. Mona uses tempered safety glass for a solid, premium feel in a semi-frameless bypass design.
  • 1-year warranty. Mona is a pre-made, standard-size door, so it carries 1 year, including when we install it.

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?

The installation visit itself typically takes 2–3 hours. Including measurement, the whole process typically takes 10–15 business days; after measurement, it is typically 7–10 business days. After a free consultation and quote, we measure at your home, then your door is prepared and installed.

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?

Usually, yes. If your old door can stay in place until installation day, our crew removes it and hauls it away during the installation visit. If it has to come off earlier, for example because it's in the way of measuring or you'd like it removed before installation, there's a separate charge. Older tile can occasionally crack as an old door comes off; if we need to come back for that, the return visit may be charged. Your quote confirms the details.

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 1-2 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.

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, order preparation and in-home installation, plus removal of your old door during the installation visit where possible. Get a same-day quote with no obligation.

Why pay for install vs. doing it myself?

Two reasons: (1) Professional measurement: we confirm the standard size fits your opening before installing. (2) Done in one visit by certified installers: most homeowners value the half-day saved over the install premium.

What does the warranty cover?

Mona is a pre-made, standard-size door, so it carries a 1-year warranty, including when we install it. Plastic seals and door sweeps are wear items handled as yearly maintenance. See our warranty policy for the full terms.

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.
