How to cover wet or humid windows

Steam, salt air, and damp rooms destroy untreated wood and some fabrics. Spec wipe-clean vinyl mini or PVC faux wood and keep real wood out of wet zones.

Common in: Houston · New Orleans · Tampa · Miami · Charleston

Moisture changes the product choice

If the glass routinely sees steam or coastal air, material matters more than style trends.

  • Bathrooms and laundry rooms
  • Coastal and Gulf interiors
  • Pool bathrooms and spa halls
  • Post-flood rebuilds (see storm guides)
  • Boat and cabin wet zones

Mounting by material & situation

Choose mount from depth and obstructions first, then pick vinyl, faux wood, or rollers for the room’s moisture and light needs.

1" vinyl mini blinds

View product line →

Wipe-clean vinyl for baths, secondary rooms, and moisture-prone openings.

  • Inside mount — adequate depth

    Measure width at top, middle, and bottom. Order the narrowest reading. Confirm ~1" clear depth for the headrail.

    Min depth:
    ≈ 1" clear
  • Outside mount — shallow frames

    When returns are thin or trim eats depth, outside-mount on flat casing with overlap on each side.

  • After water exposure

    Replace swollen or moldy treatments with vinyl — do not reinstall damaged fabric or wood.

2" faux wood blinds

View product line →

Moisture-resistant PVC faux wood for living areas — not untreated real wood.

  • Inside mount — living rooms

    Pro often used

    Needs more depth than mini blinds. Measure both top corners before assuming inside mount.

    Min depth:
    ≈ 1½"–2½"
  • Outside mount on builder trim

    Production casings sometimes leave uneven returns — outside mount keeps the headrail square.

Clean fabric lines for wide glass, sliders, and blackout sleeping rooms.

  • Inside mount cassette

    Pro often used

    Confirm unobstructed depth for the tube and brackets. Deduct per product rules when ordering.

    Min depth:
    Check cassette depth
  • Outside mount / face mount

    Use when mullions, handles, or shallow returns block inside mount — common on sliders and storefront.

Frequently asked questions

Are faux wood blinds OK in bathrooms?

PVC faux wood is built for moisture better than real wood. For small baths, vinyl mini is usually enough.

What if blinds already smell musty?

Replace them. Porous materials that held moisture are not worth cleaning for a permanent install.

Is this the same advice after a hurricane?

Yes on materials — see /guides/replace-water-damaged-blinds and /guides/blinds-after-hurricane for storm-specific steps.
