Available Finishes

A bright, reflective finish that keeps Mona's sliding hardware visually light and blends into most existing bathroom fixtures.

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

A bold contrast finish that frames Mona's clear glass and makes the sliding hardware read as a deliberate design line.

A warm, low-sheen accent that gives Mona's sliding hardware an upscale, modern-traditional feel.

Frequently Asked Questions
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.
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.
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.
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.

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.
