5-star hotel bathrooms where switchable glass / smart film goes clear↔opaque in 0.1 seconds — lifting ADR · RevPAR · OTA reviews · syncing Opera PMS · housekeeping scenes · compare Smart Film + Aquaris™ PDLC/PNLC (existing-room retrofit · batch 5 rooms/day) vs Smart Glass Tempered Laminated (new build · soft refurbish · safety glass · hotel insurance) · real projects: Pullman 662 rooms · Aman Nai Lert · Four Seasons Private Residences
Why choose Smart Film · see the comparison with Smart Glass below ·
Today's 5-star, resort and boutique hotel bathrooms aren't just functional — they're a signature amenity guests post to Instagram and Tripadvisor · Smart Glass (switchable privacy glass) or Smart Film (switchable PDLC / PNLC film) switches clear↔opaque at the touch of a button = an OTA-review lift that can raise ADR by 15–25% from junior suites upward.
But a hotel bathroom differs from a home one — showers run 24/7 at 99% RH, so it needs Aquaris™ Weather Resistance rated for spa-grade humidity · installation must not disturb guests (a low-season window) · sync the PMS (Opera · Mews) · housekeeping scenes · and the Safety Glass requirement of hotel insurance = Tempered Laminated EVA anti-shatter.
This page compares the two options with an estimate for a 6 sqm hotel bathroom (a junior-suite bathroom) + an ROI calculator for a 50- vs 200-room hotel · real projects include Pullman Hotel G (662 rooms) · Pullman Phuket · Aman Nai Lert Bangkok · Four Seasons Private Residences.
Clear ↔ frosted instantly · switch the moment a meeting starts or breaks · no need to draw blinds
Switch off instantly from wall switch / app / Smart Home · blocks light to protect furniture and TV screens
So seamless it looks like no film was installed · the hallmark of the InHouse install team
Thai brand owner · direct service with no middleman · Film 12+ · Glass 15+ yrs base · +50% Premium boost
Clear glass looks modern but creates new problems — Smart Film (retrofit) or Smart Glass (factory-built) solves the three key ones
Tripadvisor · Booking.com · Agoda · Google reviews · guests mention bathroom curtains/blinds as "feels dated" more and more often · a review score dropping 0.3–0.5 stars = an 8–12% fall in booking conversion · older un-refurbished hotels lose their competitive edge to rivals who invest in the Sexy Bathroom
A hotel bathroom at 70%+ occupancy × 365 days = the shower / tub runs every day · 99% RH around the clock · steam + soap residue + cleaning chemicals (chlorine bleach · vinegar) · ordinary PDLC smart film absorbs water and degrades in 2–3 years · needing replacement + disturbing guests = an engineering nightmare
An operating hotel can't close a whole floor/building to renovate · it has to batch within the check-out window (11:00–15:00) · drilling/grinding noise disturbs the adjacent room's guests · risking liability claims · Smart Film / Smart Glass has to install quietly · cleanly · with no dust
Glass in a wet-zone bathroom (a slip-hazard zone) must be <strong>Tempered Laminated EVA grade</strong> per IBC 2407 · NFPA 80 · ANSI Z97.1 · hotel insurance (Chubb · AIG · Allianz hospitality) mandates it · ordinary clear glass that shatters and falls = a large liability claim · Smart Glass Laminated = compliance built in · Smart Film depends on the existing glass (its certification must be verified)
Luxury hotels run Opera · Protel · Mews PMS + a Crestron in-room tablet + AI voice control + a housekeeping app · but the old bathroom curtains/blinds have no API · staff control them by hand · losing time hundreds of times a day · InHouse Smart Film / Smart Glass syncs with the whole system
Switch clear ↔ frosted in 0.1s to suit the moment — a Smart Film advantage that frosted film cannot match
glass 100% clear · lights 100% · welcome music playing · the guest opens the door to a Sexy Bathroom showcasing the design · an instant Instagram moment · a review-mention lift
glass opaque · warm lighting 30% · fresh towels folded · a chocolate on the pillow · piano music · ready for a bedtime spa routine
glass 100% opaque · candle lighting · spa music through the in-room speaker · the steam-exhaust fan starts automatically · the water temperature pre-set · privacy guaranteed
glass clear · the full Sexy Bathroom on show · marble tile · a Hansgrohe rain shower · a freestanding tub · = the signature photo every guest takes · an OTA-review upload
glass 100% clear · lights 100% · staff see every dirty corner · they clean faster · turn-around time drops 5–10 minutes/room · throughput rises
Both use the same PDLC/PNLC technology — the difference is retrofit (film) vs factory-built (glass)
InHouse engineer recommendation: In a hotel bathroom, where Smart Glass wins is the Tempered Laminated EVA grade that passes hotel insurance + IBC 2407 life-safety code · glass that breaks without falling is mandatory in a wet zone · this is why the Marriott · Hilton · Hyatt brand standards mandate factory-built switchable glass in new builds · but some Pullman/Aman properties choose Smart Film + Aquaris™ for a soft refurbish because a retrofit in an operating hotel can be done within the check-out window · with far less revenue impact than a new build.

The glass wall between bedroom and bathroom in a junior suite · suite · executive room — a full frameless pane · opaque by default · clear in Showcase Mode · the most-photographed spot for social media
Shower glass of 2–4 sqm · sliding or hinged · needs Aquaris™ to withstand constant steam · Tempered Laminated for a Walk-in Steam Room (high temp + humidity)
Glass between the vanity area and the bedroom · partial privacy while doing make-up / dressing · Smart Film goes 100% clear so a couple using it together never feels cramped
A bathroom window onto a balcony / city view · Outdoor + Aquaris™ withstands UV/IR · blocks daytime light + takes in the night view · syncs a sunrise/sunset schedule
Junior suites and up with glass between the living area + bedroom · clear by default (open room flow) · opaque when the guest sleeps or a couple wants privacy
The glass door of a spa room on the wellness floor · opaque by default (treatment privacy) · clear when welcoming a guest during consultation

CLASSE Ratchayothin townhome, Lat Phrao District, Bangkok
The CLASSE townhome is designed with a spa-like bathroom, open with a clear glass divider, but in actual use I felt I could be seen from outside the house. So I wanted technology that turns the clear glass opaque in a single second, without losing the sexy-bathroom concept I love.
Switch to Spa Mode in 0.1 seconds / clear mode keeps the concept intact
"Once InHouse Smart Film was installed, the bathroom became the private spa I wanted, with 100% privacy in use. Clear when no one's around still shows off the beautiful design. The crew concealed all the wiring, and the remote is very easy to use. Very worthwhile."— Khun Peet (private individual)
The Rise Sukhumvit 39 condo, Watthana District, Bangkok
I want the clear-glass bathroom to be private in use. I don't want blinds because I worry about mold buildup and they don't match the room style. I want a material that turns opaque quickly and is easy to clean.
Easy to clean with no mold stains / press opaque to block the view instantly
"Far better than blinds — press opaque instantly with no pulling, no mold buildup, and it matches the room style perfectly. Natural light comes in beautifully, and the bathroom looks far more luxurious than before."— Unit Owner · The Rise Sukhumvit 39
The Noble Ekkamai 22 project, Watthana District, Bangkok
I like a clear, open glass bathroom, but in real use it feels too exposed and I'm not quite used to it. Adding blinds means scrubbing soap scum and the mold that loves to build up. I want something that makes the bathroom more private but cleans up with just a wipe.
Stains wipe off easily with no germ buildup / switch opaque or clear on demand, the room looks open and spacious
"It's been great in the bathroom — no more mold or soap scum, just a wipe and it's clean. Press opaque for privacy, and when clear the bathroom still looks open and beautiful as before. It's easy to use every day."— Homeowner · The Noble Ekkamai 22
TAIT Sathorn Twelve condo, Sathon 12 Alley, Bang Rak District, Bangkok
My condo bathroom door is clear glass. I want it opaque when I shower or have friends over, but I don't want blinds because I worry about mold and mustiness. I want a material that's easy to wipe and looks upscale to match the room's decor.
Easy to clean with no mold stains / press opaque instantly, and the room looks far more luxurious
"No more mold or mustiness — the bathroom door just wipes clean, and pressing opaque makes it fully private. The bathroom looks far more upscale; every friend who visits says it's as beautiful as a luxury hotel."— Unit Owner · TAIT Sathorn 12
Krungthep Kreetha 20, Alley 8, Saphan Sung District, Bangkok
I made my bathroom with a large clear-glass pane. I wanted to block the view while showering, but not go fully opaque. I heard there's a dimmer-type glass that gradually adjusts the frosting — that's what I want, so the room feels soft. And the material has to be strong and durable.
Dim the opacity as much as you like / strong, durable glass that's easy to wipe clean
"The dimmer system is excellent — I can gradually adjust the frosting as I like, and the bathroom looks soft when it's set to mid-level. The glass is strong and moisture-resistant; after all this use it still looks brand new."— Homeowner
Samsung Electronics Office, King Square Residence, 2nd Floor
We wanted the meeting room in the Flagship Store to reflect technological leadership. Beyond privacy, we wanted a solution that cuts equipment clutter — like a projector screen — so the room looks as clean and cutting-edge as possible.
The space looks clearly more modern and cutting-edge / the glass serves two functions, both privacy and a presentation screen
"The meeting room in the Flagship Store looks cutting-edge, befitting Samsung. The glass is both a projector screen and a private partition wall in one — press opaque for a confidential meeting, or project a presentation onto the glass. Visitors see real innovation, not just products."— Samsung Flagship Store Manager
